Chapter Four

"The country of a thousand vehicles has a thousand parts of its land, with a total of 90 billion steps. Ask its square geometry?"

This is a sample question in "Nine Chapters of Arithmetic". There are only simple unit conversions and the square root of billion-level digits. Naturally, it is not difficult. He answered easily, "310 six miles and 68 steps. You can get the square root directly. .”

"Kongsang has a sacred tree. It grows ten feet at the first year, half a foot at the next year, and half at every year. Ask, after a thousand years, how high will it be?"

Without hesitation, Dianzhi responded casually, "Two zhang."

Qingyun stuck out his tongue and continued to ask, "Today there is a round granary, six feet next week, seven feet last week, and six feet high. New rice will be entrusted, and the tip will be one foot taller. Ask, how much is rice?"

After listening to this question, Jizhi suddenly looked solemn, and turned to Chen Wenzan and asked, "Did your father tell Brother Chen that he must solve these questions before he can leave home?"

Chen Wenzan nodded, "My father specifically asked me to go through my husband's approval. Otherwise, I will have to supervise my studies and I can't travel far."

Ji Zhi sighed, glanced at the three of them, and finally stopped his gaze on Hu Caiting.

I saw the latter smiling like a flower, with a naive look on his face, and he didn't look like he could hide his thoughts at all.

I wish I was worrying too much, and I muttered in my heart, "I can't solve this problem. Brother Wen Zan still needs to ask my father for advice. I am also powerless about today's matter. Brother Wen Zan is afraid It's going to be missed."

Calculating the volumes of cones and columns was originally difficult.

But looking at the whole world, it can be calculated actuarially that those who are not bad in grains of rice are only ten fingers, and half of them may fall in the ancestor's family.

Chen Daoju was afraid that it was inconvenient to explain why, knowing that Qingyun could not be stopped this time, but he wanted to keep his son Wen Zan at home.

Zu Tingzhi often went out with his father to survey and map, and followed his master to collect medicine and make alchemy.

He thought to himself that the change in Tan Palace back then was, in the final analysis, an internal struggle between sects.

Therefore, it is hard to predict the good or bad luck of this trip to Wei, and the Hu Caiting whose master's background is unknown cannot be fully believed.

Perhaps Uncle Chen and his father had already been aware of today's situation. Uncle Chen had already guessed that Qingyun would come to find him when he left to calculate the scriptures, and his father "coincidentally" planned a trip to the Northern Wei Dynasty for him. It is an entrustment.

Thinking of this, there was an apologetic smile on Tinzhi's face, as if he was still thinking about something that couldn't be solved.

Unexpectedly, Chen Wenzan was very free and easy, "Hey. I don't know swordsmanship in the first place, and it's a burden for you to carry it. I'd better ask Mr. Zu for advice, and first improve my brain. My father also hopes that I can use this to make a name for myself in the future. , ask for a living."

Hu Caiting pursed her lips, and patted Chen Wenzan's head hard, "You need to improve your brain! Read more books, maybe you can become an emperor!"

Chen Wenzan shook his head, and choked out angrily, "Cut, last time, the teacher of Jizhi did a fortune teller for me. He said that my fate coincides with the Ninth Five-Year Lord, and my future blessings are endless. I shouldn't be too far away from the dragon chair." Mr. Huayang's hexagrams have always been very accurate, Brother Tun, don't you think so?"

Zu Tingzhi was also very helpless towards his optimistic disposition. He spread his hands, and the corners of his mouth slightly raised in a playful way, "I hope it will be right this time! Master also said that I can marry a princess. To be honest, apart from fortune-telling, I obey everything sir."

Cai Ting lightly rubbed Qing Yun's arm with his shoulder, and asked mysteriously, "Has Mr. Hua Yang calculated your fortune?"

Qingyun shook his head slightly, "Uncle Chen said that Yi Xue is the way of life, not the art of seeking good luck and avoiding evil, so..."

Chen Wenzan snorted coldly, "Brought my father out again. My father also said that Mr. Hua Yang is not an extraordinary person. Hearing what he said is better than studying for ten years."

Then he squinted his eyes and said to Caiting, "He is afraid that his fate will be too weird and scare you. Mr. Hua Yang said that brother Qing is the phase of 'nine dragons around the pillar'. He is the pillar, the pillar of the world , in his life, he will meet a lot of nobles with real dragon fortune to walk around him. Well, I am the first one. Haha~"

The fetters with the real dragon's destiny, meeting one, for ordinary people, it is a blessing in three lives.

Kowloon around the column?What kind of monster is this guy?

Hu Caiting murmured in his heart, no matter what, Luojing is now a tiger dominating a dragon, and an undercurrent is surging, maybe this fledgling boy is the fate of breaking the game?
What about your own destiny?What about the fate of the tribe?

Hey?Even if the emperors of the Northern and Southern Dynasties are counted, it is far from enough to count the Nine Dragons Surrounding the Pillar. Could it be that besides the Middle Earth, the barbarians and the five barbarians, future emperors will be intertwined with his fate?So……

"Hey, what are you thinking? Are you really scared?"

Looking at the surprised gazes from the three of them, Hu Caiting knew that he had lost his composure just now, so he forcefully said, "I think I'm a little tired. I've been running for a whole day without a break. I have to go on the road tomorrow."

Dian Zhi smiled knowingly, and placed Hu Caiting in the bedroom behind the courtyard to rest.

This star watching pavilion is not a meeting place, there is no guest room, the three big men can only spend the night in the pavilion.

In the early morning of the next day, the Hucai Pavilion was awakened by a rush of golden singing. In the dimness, the room was full of splendor and colorful colors. Several beams of light converged on a metal column on the inner side of the gable wall, reflecting the blazing white light. Can't look directly.

Caiting was startled and amazed, and suddenly woke up, but the beams of light suddenly disappeared, replaced by the soft natural halo in the morning light.

The three people in the pavilion talked a lot of gossip last night, and they were still in a dream at this time, but Hu Caiting rushed in shouting all the way like chicken blood.

The three of them rubbed their sleepy eyes reluctantly and smiled wryly.

Tinzhi yawned and said, "What, I said she would come early in the morning to wake us up so that you could go to bed early last night."

Qingyun laughed loudly, "She looks more nervous than when I first saw those damn things of yours."

"Are you guys just looking at my jokes purely, so you don't remind me to beware of those weird mechanisms?" Hu Caiting's face was sullen, with two willow eyebrows raised, like a pair of machetes, as if they would be cut off if they disagreed. Obviously irritated.

Ji Zhi waved his hand, "I don't dare to watch the girl joke, but if I remind you in advance, there will be no such sense of mystery, wouldn't it be a lot of fun? It's just a small trick to wake me up and dance the sword when the weather is fine. It’s not worth it, to put it bluntly.”

Hu Caiting knew that the other party didn't have any malicious intentions, and with the surge of curiosity, his anger was diluted, "How did you do that? Those light curtains are still... quite beautiful. At this time, the sun is just rising, can it automatically Perceive the sun?"

"That's right.

When making the dome mirror, my father and I took some leftover materials and ground it into an eight-sided concentrating mirror, which was hung under the eaves of the east window.

When the sun rises on a sunny day, these mirrors will focus the sunlight on the lead rods of the gable.

There are actually two lead rods, and the other one is in the mechanism room next door.

The two lead rods are roughly equal in height, supporting a wooden trough with an open end, and copper beads are contained in the trough.

Usually, the wooden groove is slightly inclined to the closed end, and the copper beads cannot roll out.

But concentrated light can generate heat, and the lead rod will stretch a little when it is heated.

In this way, when the sunlight comes in, it will raise the closed end of the wooden trough, and the copper beads will roll down from the opening on the other side, and hit the copper plate below, making a sound.

When all the copper beads fall into the copper plate, the mechanism will be pressed to close the condenser, stop heating, and the temperature of the two lead rods will gradually return to balance.

And every night at midnight, when the big leaker leaks and resets, it will trigger the mechanism to release the condenser lens, and fill the wooden tank with recycled copper beads, waiting for the next sunrise. "

Concentrating light generates heat, lead rises with heat, these principles are too unfamiliar to Hu Caiting.

Even though she only heard about it in a cloud, she also believes that the mystery in this pavilion is like a miracle, and there is only awe. "I, let's get out of this damn place as soon as possible. Every step here is full of tricks, and a wrong step is a fright. The lights in the corridor will be extinguished by themselves, the incense will be ignited, the tea will be cooked by itself, and even the toilet will be cleaned by itself... ..."

"These are not difficult. In fact, we only need to find the actions we are used to to trigger them, such as opening and closing doors, sitting, standing and walking..."

"Stop! This girl just wants to leave now." So she left and rushed out without looking back.

"You guys go, I'll help you look at the Guanxing Pavilion." Chen Wenzan waved his hands to the two, as if he had made a very happy decision.

"That's what I need to do." There was a junior to help record the star map, and it was natural for him to wish for it, so he finally let go of the last worry and said goodbye with Qingyun.

It is said that the three young people walked together all the way, so they couldn't stop talking.

Especially Qingyun, who had just learned about his life experience, kept asking about the situation in his sect and the general situation in the world.Caiting and Dianzhi also took the trouble to explain based on their knowledge.

There has been a saying about the Five Swordsmen in the world since ancient times.

According to legend, the five emperors established the country with martial arts, and each passed on its secrets.
Yellow Emperor Xuanyuan Sword,
Red Emperor male and female swords,
The Qing Emperor's Banished Star Sword,
Black Emperor Xuanwu Sword,
Baidi Spirit Ape Sword,
And for the ancient five.

The Xuanyuan Sword of the Yellow Emperor was lost for a time, and when the Chu and Han dynasties fought for hegemony, King Xiang got its fragments and proud of the world with the Overlord Sword.

Sun Jian of the Three Kingdoms also studied the remnants of the Overlord, and when his son Sun Ce died, the essence of Xuanyuan Sword was lost.

Ma Mengqi from Xiliang's Ma family is domineering and fierce, and looks like Xuanyuan, so he is one of the five sword sects, the Xizong sect.

But since Ma Chao's death, there are few masters who practice this method, and among the five schools, it is gradually declining.

The Red Emperor Sword was passed down to the Liu family. From Liu Bang's cutting of snakes to establish his prestige to Liu Xian's patrons' application of the law, it took shape during the 500 years of the Han Dynasty.

Liu Song of the Southern Dynasties welcomed his skills. After the fall of the Song Dynasty, Liu Chang, the nine princes, fled north to Wei and was named King of Song.

Although the King of Song is a false title, but Liu Chang built Zhan Snake Villa separately, claiming that the Liu family is the master. Compared with the emperor's family back then, the status in the world has not diminished, so he can claim to be the authentic sword sect.

The Qingdi sword was obtained by the righteous man Bian Sui, who was originally the number one general in the late Xia Dynasty.

When Tang attacked Xia Jie, he made peace with Bian Sui first, so the king of Shang won the world. He wanted to let the world belong to Bian Sui, but he refused with death.

Shang Tang felt his high righteousness, and took Bian's sword as his national skill.

This branch has declined since the death of Zhou Dynasty, and then flourished in Bian Zhuangzi, named Fenbafa.

Many people in the Spring and Autumn Guards practiced it, and there were many branches passed down, collectively called Dongzong, among which the Nie family and the Xiao family were the leaders.

Hei Di Hua Zhenwu was secretly passed down in Taoism.

Since Ma Mingsheng in the Han Dynasty created the Lightning Method, it was passed down to Yin Changsheng, and it flourished in Wudang and Qingcheng.

The current suzerain is Zu Tingzhi's teacher - Tao Hongjing, Mr. Huayang.

Although Daozong's momentum is not as powerful as Zhan Snake Villa, Tao Hongjing's swordsmanship is the best in the world, which is the consensus of the world.

Moreover, Mr. Qi is well versed in ancient and modern Vientiane, and he is proficient in everything from Qimen spells, Danshiqihuang, forging, casting and smelting.Therefore, the rivers and lakes also have to give up three-point thin noodles and Daozong.

As for the lineage of Baidi, since Baidi was expelled in the past, there is no descendant, only murals are left to explain his sword meaning.

It happened that there was a psychic ape man, whose practice of viewing paintings made him see the light of day again.

The spirit ape is passed on to Yue Nu, who was once the teacher of Yue State.

After Yue State was destroyed by Chu State, some clansmen fled north to Qilu, and the Yue Nv Sword was spread to the north.

King Wei of Qi set up the Jixia School Palace to give gifts, which was a great success, so he imitated his system to give swords, and worshiped Tanzi as the king of heaven, so there is a Tan Palace.

The result lived up to the prestige king's expectations, the Tan Palace has peaches and plums all over the world, and at the peak of its prosperity, half of the world's swordsmen came from this vein, and it was said that the world's swordsmanship came from Yue Nu.

The second king of the Tan Palace created the method of rising and falling, condensing the essence of Yuenu's sword spirit, and it was only for the family of the Qi king to pass on.

Wang Ju called himself Tangun for the merit of Tanzi.

Afterwards, all the masters of the Tan Palace were from this custom, and the title of Tangun could only be inherited by the branches of the Qi royal family.

Among them, the surnames of Tan and Wang accounted for more than half of them.

Among the Tanguns, Wang Jian of the fourth generation who served as the national teacher of the Jizi Kingdom, Wang Yue of the 27th generation of Tangun who was a teacher of Cao Wei Guoshu, and Tan Daoji of the 36th generation of Tangun, a famous general of the Southern Song Dynasty, are the most famous.

After the death of Qi, there was no Tan Palace, but the descendants still called themselves Tanzong.

And Tan Daoji was convicted because of the incident, and Emperor Wen of the Song Dynasty hated him for "supporting bandits and self-financing", and carried out a large-scale purge of Tanzong in the Southern Dynasties.

There is Qingyun's father, Qing Yihan, the No. 30 eighth generation Tangun, who led the disciples to regroup into forces in the Northern Dynasty.

In the Northern Dynasty, the Tuoba clan was from the Hu people of Xianbei. Qing Yihan did not want to see the country being taken over by the Hu captives, so he followed the example of his ancestors and assassinated the king of Wei.

Since then, Tan Zong has been reduced to a rebellious party in both the northern and southern dynasties.

More than ten years ago, the disciples who escaped to the south could only live a secluded life like Chen Daoju.

However, although people in the world still respect the Fenstrike method of the Eastern sect, the rising and falling method of the Tan sect, the Gu Ying method of the Jian sect, the lightning method of the Dao sect, and the shooting method of the Western sect, they are the five sects in the world.

But Tanzong and Xizong have been silent for a long time. If it weren't for the fact that there are no outstanding sword sects emerging in recent years, the two sects only rely on the legendary prestige, and the status of the preservation sect is very reluctant.

"My fathers used to be proud of the Jianghu back then, how can we just watch the 700-year glory of our sect fall to my generation! I want to fulfill my father's will, assassinate King Hu, restore rivers and mountains, and strengthen my Tanzong!"

Previously, Qingyun lived in seclusion and didn't know his troubles. Now that he first learned about the old affairs in Jianghu, he couldn't help being motivated and his chest heaving.

If no one pulls the rein, this kid is afraid that he will cause trouble, Zu Ting already had such a plan in his heart, "Brother Qing, don't act on your will.

When your father was alive, Tanzong's momentum was in full swing, and this matter was not yet acceptable.

Now the crowd has no leader, and a lot of waste is waiting to be done.

However, the Empress Dowager Feng of Wei Gong had passed away, and Tuobahong held the power alone.

One ebbs and another, hope is even slimmer.

If it fails, the individual's life is still small,

But Tanzong's remnants will inevitably have to endure another storm, and it will be even more difficult to rise in the rivers and lakes again. Wouldn't brothers Qing become sinners? "

Qingyun frowned, knowing what Tunzhi said was reasonable, but he had never encountered such an important decision before, and he didn't know how to weigh it.

"Although there are three households in Chu, Chu must die in Qin! Brother Qing, I support you!"

Cai Ting hooked Qingyun's shoulders, and patted it lightly a few times, his eyebrows were bent upwards like a crescent moon, and a flowery smile bloomed in front of Qingyun's eyes.

The orchid fragrance he spit out seemed to have entered his throat and penetrated directly to the bottom of his heart.

Qingyun's heart was already on fire, but at this moment, there was a stream of heat gushing out from the bottom of his abdomen.

What bold words, swearing and swearing, as if they were chewed up and held in the mouth, they came out all at once.

Schools, Hualu, Jiangshan, and righteousness are all blinding fly ashes.

And the real torrent behind him was still suppressed by Qingyun's lower abdomen, and he didn't let it out with his words.

Seeing this, Zu Tingzhi could only shake his head.

He is an outsider about the Tanzong matter, so it is not appropriate to persuade him at this time.

What's more, Fang Gang's blood is mixed with the young boy and girl's love, if he persuades him again, he may not even be able to sit in the position of brother.

Now that the current situation is turbulent and thieves are rampant, several people first chose the waterway in order to be safe.

But the boat has been sitting for a long time, it is not grounded, and it is inevitable to be boring.

First of all, Caiting couldn't sit still, and decided to buy horses in Xuzhou and change to the official road.

"I'm not a new Hina debut,"

Hu Caiting glanced at Qing Yun intentionally or unintentionally, but the latter could only pretend not to know, "I have been running business with my parents since I was a child. When I arrive in Wei State, there is no need to worry about me. There is a business in Xuzhou, and my parents have many There is a relationship. I can ask him to help us buy some Wei Guojun horses with imprints, those Jianghu Xiaoxiaos have seen each other, and they dare not make random decisions."

Seeing that she was serious, he also acquiesced.

"Junior Brother Qing, this Xuzhou is a dragon's den. In the past when ancestor Peng founded the country, Chu and Han fought for hegemony, Sun Cao and Liu divided the world into three parts, and now the Song and Qi aristocratic families in the Southern Dynasties, all the emperors are not unrelated to Xuzhou. Your appearance of the nine dragons encircling the pillars, in the Hang around here more, maybe you can catch a few real dragons."

"Senior Sister, you're making fun of me again." Although Qingyun evaded, there was no sign of any concern on his face.

"There seems to be some big event ahead, so lively. This kind of battle is rare in Guangling." If it wasn't for Tiezhi's reminder, neither of them paid attention to the dense crowd at the intersection of the street.

When the wayfinder asked him what was going on, it turned out that it was Xiaolong Wang Yuanfaseng who was looking for a martial arts teacher.

Little Dragon King's father, Jiangyang King Tuoba Zhongkui, is known as the number one warrior of the Tuoba Clan. He entered Zhongnan alone in order to quell the Gaiwu rebellion.

A pair of young sons left by King Jiangyang were adopted in the palace, and they met very kindly, but for some reason they were not granted titles after the coronation ceremony.

Yuan Faseng was only granted the title of General Longxiang, so he called himself the Little Dragon King.

It is a serious crime for the royal family to privately use the king's title, but the family tree of the little dragon king is quite respectable, two generations higher than the present, and Tuoba Zhongkui is one of the best warriors in the clan.

Therefore, the court treats Monk Yuanfa extraordinarily, and he doesn't take it as disobedience, and he even used this title on informal occasions, so the name of the Little Dragon King can be regarded as solid.

The Little Dragon King has been like a father since he was a child, and he is addicted to martial arts.

Emperor Wei Tuobahong promoted Han surnames, and Yi Tuoba became Yuan surnames. Yuan Faseng was the first to support them, because it was easier to get close to people in the Jianghu with Han surnames.

In recent years, he has hired martial arts teachers with high salaries. If he doesn't have the ability to make ends meet or has a desire to hide his secrets, he will naturally end up miserable.

But even if he taught him wholeheartedly, with the savvy of this little monster, he would be able to excel in a few years, and beat the teacher to death or injury.

Everyone knows that this job is a hot potato, no matter how high the salary is, no one worth a penny dares to take it, so every recruiting will attract a crowd of curious people, and it becomes a grand event, which is cheaper for businessmen.

"This little dragon king is so arrogant, who else will apply for it?" Qing Yun wondered.

"Hey, this little brother doesn't know anything.

The current governor of Xuzhou is Liu Chang, the king of Song Dynasty, the owner of Zhan Snake Villa, and the Yuan Fa monk was originally here for him.

But Song Wang naturally didn't want to accept this thorn, so he said he was sick and shirked.

But even if he shirks, how dare he turn a deaf ear to it, he can only use his connections in the world to find some strange people, and select capable ones for the little dragon king to choose.

The referees for this selection were Liu Chengwu, the son of King Song of Zhan Snake Villa, who represented the promoters of Jianghu, Prince Yuanyu of Guangling, who represented the clan of the Great Wei Dynasty, and the little prince himself. "

"King Guangling, your father's land has been confiscated by Emperor Wei." Qing Yun nudged Zu Dianzhi gently with his elbow, and whispered.

"It's rare to see, but it's strange. Now there are not a few states and counties controlled by the Wei State that were enfeoffed and remoted in the Southern Dynasty. Continue to watch your excitement!"

The three of Qingyun are all martial arts practitioners, so they found a higher building and climbed up.

It seemed that many comrades had gathered on the roof, everyone smiled at each other, and then turned their attention to the field.

Qingyun stretched his neck and looked carefully, and saw that there were still four people who were not eliminated, and each of them looked unpredictable.

One of the tower-like strong men came out first, and called out loudly, "Pei Duji, who opened the stele, show your shame to the little prince!"

"""""Knock on the blackboard time"""""

Since the new school of martial arts created by the three heroes of Jinliang Gufengchen in the 50s, there have been countless creations in the description of swordsmanship.Some are simple and stern, and some are wild and unconstrained, attracting countless readers to yearn for them.

In this work, the description of swordsmanship intentionally takes a more retro flavor, and boldly traces the origin of swordsmanship.

The so-called kendo first came from "Wuyue Chunqiu".The land of Wuyue is good for sword fighting, and famous swords are produced, and the swordsmanship of Yue girls is passed down to the world.

Sword fighting and sword dancing are already common accompaniment programs during the banquet. The well-known story "Hongmen Banquet" is a portrayal of the ethos of swordsmanship and fighting at that time.

Since the Han Dynasty, some famous swordsmen have appeared in official history, such as Chongda and Wang Yue.

Around the Song Dynasty, routine martial arts became popular.Routine martial arts is an important part of traditional Chinese martial arts. It mainly trains autonomic responses, similar to our modern training for driving and typing.Between the victory and defeat of high-speed confrontation, the vast majority of reactions are not made after brain thinking.Therefore, martial arts routines are not dross, but in actual martial arts confrontation, it is impossible to get rid of the constraints of physical fitness such as strength, speed, and impact resistance, and physical fitness is the core of modern competitive martial arts research.

It was also in the Song Dynasty that the kendo of the island country on the other side of the sea began to sprout, and the "one-sword style" that mainly practiced chopping methods just appeared.

The full flowering of Japanese swordsmanship was during the Ming Dynasty in China.It is recorded in the military essay "Zhenji" of the Ming Dynasty in our country: "There are skills in using swords."There are sword scriptures in the law, and swordsman in the art, so it is unpredictable.There are dozens of families who know it, but Bian Zhuang's twisting method, Wang Ju's rising and falling method, Liu Xianzhu's Gu Ying method, Ma Mingwang's lightning method, Ma Chao's shooting technique, and the swords of the five schools are mediocre.Scholars of Dasein seek it carefully and obtain its secret.

We can see that there were already dozens of sword techniques in China at that time, and the five ancestors were the most important.Among these dozens of "small sword types", there are also swordsmanship and martial arts that were mastered in the Ming Dynasty, such as Wudang sword, Taiji sword, and Bodhidharma sword.Now we have to respect the Five Patriarchs for all the martial arts classics that we play so well, so what kind of demeanor of the Five Patriarchs' sword should it be admirable?
Therefore, the basic setting of the Kendo sect in this work is based on the fifth ancestor of the sword sect.

p.s. In Chapter 1 of this work, the use of mechanical elevators was mentioned, and some readers left messages questioning the feasibility of mechanical elevators.In fact, based on the height of two floors, mechanically driven elevators are absolutely achievable.It is only necessary to cut/establish the connection between the elevator and the heavy object with the mechanism.Going upstairs depends on the weight falling to the ground to do work, and going downstairs depends on the frictional damping of the weight moving in the track to decelerate.Of course, due to energy conservation, the weight of the heavy objects carried when going downstairs will be less than that required for going upstairs.But it doesn't matter, the star gaze pavilion has a hydraulic device, which can trigger the mechanism to fill it with hydraulic power when the elevator falls and touches the floor.

Most of the writers you see are literary and bold, and it is really embarrassing for them to pay attention to industrial design.Fortunately, the author has a background in science and engineering, and has 20 years of manufacturing experience certification. Do you dare to say that the ancients could not make advanced devices with limited technology?nonexistent!Do not rely on time travel, go to the sky and enter the earth, black technology is everywhere.All the black technologies mentioned in this work either have a source or a reasonable feasibility analysis, let’s put it here for now, welcome to play!
