The Jin army besieged the city, and the Song emperor’s daughter died

In a remote small workshop in the Academy of Song Dynasty, Zhao Fujin saw a strange four-wheeled vehicle.

There is a platform above the wheel, and a large wooden box is connected to the platform. The wooden box is closed on both sides. The side facing the front has five rows and five columns, with a total of 25 small holes.

Look at the size of this small hole, which is about the thickness of the mouth of a bowl.

On the back side, there is a cabinet door that can be opened and closed.

Zhao Fujinjin opened the cabinet door curiously and wanted to see the structure of the box, but he did not expect that the box was empty.

Zhao Fujin looked at Mo Ming in confusion: "What is this?"

Mo Ming was stunned and said: "It's a car. Didn't the official see the wheels?"

As he spoke, he squatted down and patted the wooden wheel.

Zhao Fujin glanced at him sideways: "I know this is a car, but what I'm asking is what is the use of such a car?"

Mo Ming stood up and introduced with pride: "This kind of vehicle, I heard from our ancestors before, seems to be called a continuous crossbow shooting vehicle, which can launch a large number of large and small crossbow arrows in a short period of time, but during this time , I saw that everyone in the Academy of Sciences of the Song Dynasty was working on thunderbolts, so I thought, since it can fire a large number of crossbows in a short time, can it be improved so that it can fire thunderbolts? It is more convenient than throwing them by people, isn't it? "

Zhao Fujin walked around the car, turned back to the front of the car, looked at the 25 small holes, and fell into deep thought.

Good guy!
Zhao Fujin just wanted to exclaim, good guy, you are going to make a rocket car with continuous fire.

If this had been anyone else, Zhao Fujin would have thought that he was very clever, but remembering that the Mohists were good at mechanisms and were extremely proficient in mechanical principles, Zhao Fujin asked in confusion: "But there is nothing in your box?"

Mo Ming scratched his head and said with a smile: "The mechanism for firing crossbows and the mechanism for firing thunderbolts are definitely different. Thunderbolts have to be ignited, so I haven't figured out how to arrange the mechanisms inside. However, it is only temporary. , give me some time, I will definitely be able to think of a way."

Although Zhao Fujin felt it was unrealistic, he still didn't want to dampen a person's courage to explore.

Besides, how can you be sure that someone can’t do it?

Thinking of the Mohists, Zhao Fujin thought that during the Spring and Autumn Period and the Warring States Period, they had already conducted research on basic sciences such as geometry, optics, mechanics, and limit theory. Although they disappeared and never showed up again, who knew that they were close to 2000 How much improvement has I made in the past few years?

Looking at the two people in front of him, Shen Qiong seems to prefer tinkering with chemical things, while Mo Ming seems to be more hands-on.

That being the case...

Zhao Fujin came up with a bold idea: "Mo Ming, have you ever thought about a kettle?"

"Kettle?" Mo Ming was puzzled, what's so interesting about this thing.

"I mean, when the water is boiling, why does the lid of the pot get pushed up?"

A simple question made both Shen Qiong and Mo Ming stunned.

These small details that are common in life and taken for granted. If no one asks, who will care about these. But if others ask, they seem to think that there is a big reason for it.

"If the heat generated when a small pot of water boils can lift a pot lid, then if the entire Bian River water boils, what will it lift?"

Zhao Fujin smiled and patted Mo Ming on the shoulder: "You might as well think about this. With your hands-on ability, think about it. If you connect a connecting rod and a crank to the pot lid, and they are connected to something else, the water Can the heat in the car be used to push it... If you think about this thoroughly, it will be much more useful than a car like yours."

Mo Ming's eyes lit up, and he thought of endless possibilities in an instant.

Isn’t the biggest problem in Mohist machinecraft the problem of motivation?

If the problem of power is solved, what kind of mechanism cannot fly?
Zhao Fujin drew an extremely abstract picture for Mo Ming, a schematic diagram of a steam engine from a middle school textbook. He lay down in front of the desk in the small workshop and explained the principle of converting thermal energy into mechanical energy in detail to help them quickly find out. As for the idea, Zhao Fujin didn't understand what the steam engine was made of and what materials it was made of to ensure maximum efficiency.

But Zhao Fujin felt that as long as the principles were explained to them, shouldn't they be the ones to worry about the rest?
If only we could build a steam engine...

The sun and the moon are renewed!

It was already afternoon when he returned from the Academy of Song Dynasty. Zhao Fujin was in a good mood and his thoughts became more active.

Although she doesn't understand Mohist's mechanism skills, she still knows a lot about Mohist thought.

Among the hundreds of schools of thought at that time, the one who was most hostile to Confucianism was none other than the Mohist school.

Mo Zhai said: Confucianism is enough to destroy the world.

One: Disrespecting ghosts and gods will cause the gods and ghosts to be displeased.

Second: Keeping one's filial piety for three years is a waste of money and manpower.

Third: Paying attention to etiquette and music is only a lewd matter of a few nobles and has nothing to do with the common people.

Fourth: Knowing your fate and obeying it, everyone should stop working and wait for your fate, right?
Of course, these four points are direct criticisms, but they do not harm the foundation of Confucianism. What makes Confucians or the emperors who want to use Confucianism to strengthen their dominance the most unhappy is that your Mohist school actually advocates equality and even advocates The disadvantaged groups should demand their rights from the aristocracy and imperial power.

Confucianism, which preaches class, cannot tolerate it, and the royal family, which is endowed with imperial power, cannot tolerate it even more!

Obviously, although Mohist thought can stimulate the creativity of the people to the maximum extent, especially in the natural sciences, it will inevitably shake the foundation of imperial rule, and it is inevitable that it will be abandoned by the imperial power.

Zhao Fujin was wondering, at a time when Confucianism is at its most declining, can Mohist thought be improved and utilized to promote the development of natural science within a certain scope?

Of course, this problem is very systematic and cannot be figured out in a short while.

Not long after returning to the palace, this idea was temporarily shelved. Before reaching the imperial study room, I saw two people waiting in front of the door. One was Qian Bing from the imperial hospital and the other was Li Bangyan.

The two of them followed Zhao Fujin into the imperial study. Qian Bing said first: "Guan family, the Emperor has been sick several times during this period, with wind, cold, humidity, mosquito bites, and last night a grass snake climbed into bed in the middle of the night. It bit the Supreme Emperor on the chest. I just diagnosed and treated the Supreme Emperor. It’s nothing serious, it’s just uncomfortable.”

Zhao Fujin sneered: "I did it myself!"

Qian Bing smiled awkwardly and said: "What I mean is that it is also hot today. If the two doors of Longde Palace are not installed, when the summer heat invades the body and the cold and heat are added together, the yin and yang will be out of balance."

Zhao Fujin sighed softly: "How about forcing the king?"

Qian Bing smiled bitterly: "My whole body is full of bruises. In this weather, mosquitoes are very poisonous."

"They don't know how to burn fires to repel insects?"

Li Bangyan then said: "It was burned, but the wind direction changed and he almost choked the Emperor to death. The Emperor asked someone to come to see me a few days ago and asked him to go to Kaifeng Mansion Prison to stay for a few days..."

"Nonsense! I put my father and brother in prison? How do people in the world think of me? How can I educate people in the world?" Zhao Fujin was dissatisfied.

Li Bangyan hurriedly explained: "I also said the same thing. How can an official with benevolence and filial piety do such a treasonous and unethical thing? So he reprimanded the visitor and sent him away."

Upon hearing this, Qian Bing suppressed a smile and looked away.

Zhao Fujin cleared his throat: "Li Bangyan, are you and Qian Bing here to speak to the Supreme Emperor?"

Li Bangyan waved his hands repeatedly: "No, no, this is all an official's family matter. How can I talk too much? I'm here..."

Li Bangyan hesitated for a moment, looked at Qian Bing, and then at Zhao Fujin: "The official has a letter."

Zhao Fujin raised his eyebrows: "Believe it?"

Li Bangyan then took out a letter from his arms and handed it over: "The officials will take a look."

Zhao Fujin unfolded the letter and frowned more and more. After reading it, he picked up the envelope and shook it. A few pills fell on the imperial desk. Zhao Fujin went up to smell it and turned around and said, "What the hell is this? It smells bad."

Qian Bing took a closer look. Since it was a pill, it was within his area of ​​expertise. He moved forward, held it in his hand and looked at it carefully. He then brought it to his nose and sniffed it, and said with a puzzled look on his face: "What is this?" Yeah?" "Isn't it a pill?"

Qian Bing took it and looked at it again: "I am stupid and can't tell what kind of herb this is. I just think... I just feel that it smells bad, like rotten meat."

Zhao Fujin was startled and kicked the prince, who was sleeping soundly under the imperial desk, and held two pills in front of it. The prince just went up and smelled it, grinned slightly, and turned his head to the side.

If dogs don’t eat it, how can it be a good thing?

Zhao Fujin frowned and thought for a moment, then asked Qian Bing: "What is the symptom of catching wind-cold, weak spleen and stomach, vomiting and diarrhea?"

Qian Bing replied: "How long will this disease last?"

Zhao Fujin estimated the time: "It must be half a month."

Qian Bing sighed: "Cold and heat invade the body and damage the spleen and stomach. It is not a serious illness at first, but if you don't treat it properly and you still eat these things, it will cause damage to the body and dehydration, which will be life-threatening."

Zhao Fujin didn't understand the Chinese medicine term "dehydration", but he could understand it literally. It was dehydration caused by vomiting and diarrhea, which was indeed life-threatening.

"How to treat it?" Zhao Fujin asked.

Qian Bing smiled sarcastically: "Guan, this medical practice pays attention to seeing, hearing, listening, and getting the right treatment... You are asking me this, I really don't know at the moment."

"It's just wind-cold plus spleen and stomach, nothing different. How do you usually treat it?"

Qian Bing frowned and thought: "If there are no other symptoms, Huoxiang Zhengqi Pills will do."

Zhao Fujin then thought about it. He didn't know if he had kept the bottle of Huoxiang Zhengqi Pills that was given to the second prince as a national gift to treat heat stroke. If he kept it, why didn't he eat it?

Seeing Zhao Fujin's frown, Li Bangyan stepped forward and asked quietly: "But the second prince is sick?"

Zhao Fujin hummed, and after asking Qian Bing to step aside, he said to Li Bangyan: "This disease is strange. This old guy Wanyan Sheng wants to take this opportunity to get rid of Wanyan Zongwang."

If there had been civil strife in the Jin Dynasty before, Li Bangyan would have been so eager to do so, and he might even have recited a poem: "Your home has the best scenery."

But last time I heard what Gao Chong said, there seemed to be some problems between the official family and the second prince...

"Ah? Is there such a thing? As long as you ask the official, I am willing to take command again, and I will meet the Ning Mansion on horseback..." Li Bangyan was impassioned.

Zhao Fujin rolled his eyes at him: "How excited are you?"

"Save the second prince!"

"Why save him?"

"Ah... this... what do the officials think, should we save him or not?" Li Bangyan asked cautiously, recalling what happened every time he misunderstood and made random mistakes.

……

……

In Qingzhou of the Great Song Dynasty, the 5 troops under Zhang Jun's command have been deployed here for more than four months since Kaifeng.

The other two lines of defense deployed with him have already played their role.

Zezhou Yiyi, commanded by Liu Guangshi, the deputy general manager of the Ma Infantry Army in Yanyan Road, took back Taiyuan in one go on the second day after the Battle of Kaifeng started.

Cangzhou Road, commanded by Wu Jie, deputy general of Jingyuan Road, had been ordered to march into Yanjing some time ago and set up camp sixty miles south of Yanjing. They only waited for the imperial court to issue an order to target the Sixteen Prefectures of Yanyun.

And he had been in Qingzhou for more than four months, and the court seemed to have forgotten him.

This made Zhang Jun very unhappy. Everyone was leading the army, so why did Liu Guangshi take back Taiyuan City and become famous?

Not to mention Wu Jie, the imperial court wanted to give him the opportunity to become king, otherwise why would he be allowed to march into Yanjing?

"Zhang Tongzhi, we don't have to be envious. Wu Jie took Yanyun Sixteen States? Isn't it child's play?" the deputy general comforted.

Zhang Jun spat: "At this moment, the main force of the Jin army has been defeated by the officials. How can the Jin army stationed in Yanyun still have the fighting spirit? Wu Jie got a big advantage this time."

The lieutenant general still didn't believe it: "Why should the officials give such incredible credit to Wu Jie? I haven't heard that Wu Jie is close to the officials."

Zhang Jun was puzzled by the reason for this. He had been thinking about it a lot these days, but after thinking about it over and over again, he still couldn't figure out the official's intention. He just secretly made up his mind: "No matter what, if I return to Beijing again, I will You must spend more time with Li Xiangguo. If you can get acquainted with officials through Li Xiangguo, then...hey, you still have to learn more from Li Xiangguo."

With nothing to do, Zhang Jun came outside the station, looked at the water of the Yellow River where the ice and snow had melted, and couldn't help but think deeply.

A year ago, Li Bangyan was still a villain in Zhang Jun's eyes who could only flatter others.

But with everything that happened in the past year, Zhang Jun's view of Li Bangyan has greatly changed. To be able to prosper in the hands of Emperor Daojun and become the right-hand man of the current official family is to say that he doesn't have two brushes. ,How can it be?

It has been some years since Zhang Jun became an official in the court during his reign.

Suddenly I realized that the way to be an official is not to be arrogant and arrogant, but to be in harmony with the light and dust.

There is no shame in hugging your thighs.

While I was thinking, I suddenly saw sails in the west. I looked up and saw ten large ships flying the Song flag heading towards my station.

Not long after, the big ship anchored and landed. The person who stepped ashore on the ship was a middle-aged man wearing a uniform of the Forbidden Army. He had a dark complexion and muscular muscles. As soon as this man landed, he smiled heartily at the shore patrol and said, "Haha. Haha, who is Zhang Jun and Zhang Tongzhi?"

Although Zhang Jun didn't know who this person was, he saw the military uniform on his body and knew he was a general from the imperial court. He quickly took shape and strode forward to greet him: "I am Zhang Jun, who is the general?"

"The commander of the navy in the capital of the Song Dynasty, Cao Yanchang, has come to do a big thing with General Zhang according to the official order!"

Zhang Jun greeted him warmly: "Oh? What's the matter?"

Cao Yanchang was about to speak when he heard someone on the deck of the ship behind him scolding: "Are we here? We are finally here. If we don't get there, I will really die."

Cao Yanchang smiled for a moment and said awkwardly to Zhang Jun: "Zhang Tongzhi, wait a moment, I forgot about that little ancestor."

After that, he turned around and ran quickly towards the ship.

Not long after, Cao Yanchang came back supporting someone and introduced to Zhang Jun: "This is General Jin Jia Gao Chong."

Zhang Jun had not heard about Gao Chong's achievements carefully and was not familiar with him. Seeing Gao Chong's half-dead look, Zhang Jun chuckled and said, "Is General Gao in bad health? Does he still have to be supported?"

Before Gao Chong could speak, Cao Yanchang explained: "General Gao is not good at water and is seasick. He has been vomiting for several days."

Gao Chong was about to speak, but his stomach suddenly turned. He turned around and ran away, and started vomiting again.

Zhang Jun looked at Gao Chong, who was squatting on the ground and could hardly stand up straight, with disdain on his face, and fisted at Cao Yanchang: "General Cao is speaking in the tent."

Cao Yanchang pointed at Gao Chong: "Wait until General Gao finishes vomiting."

Zhang Jun chuckled and shook his head: "Such a body and bones... ha..."

Cao Yanchang hurriedly stepped forward and made a shushing gesture: "Hush, Zhang Tongzhi, Gao Chongzhiyong will talk to you in detail later. Don't think that he has a low military rank and a young age, but he is called an official." Damn it, so..."

Before Cao Yanchang finished speaking, Zhang Jun rushed behind Gao Chong in three steps and two steps. While patting Gao Chong on the back, he cursed at the sentry in the distance: "Are you all blind? Can't you see that General Gao is seasick?" I feel uncomfortable, why don’t you bring some water quickly!” (End of Chapter)
