Chapter 331 Yue Wang builds tools to survey geography
Snapped!
A hailstone the size of a walnut hit the exposed rock, bounced up to a foot high, and did not shatter.

Snapped!Snapped!
Occasionally, a few more hailstones crashed down.

Those hailstones showed a charming amber color under the light of the fire.

Li Daoyuan took a look, and his expression changed immediately.

"Sulphur! There is sulfur in the hailstorm.

We had to hurry on our way, the dust and fog were poisonous, and we couldn't survive without a ventilated bunker.

Now listen to my command! "

Li Daoyuan cut off the wooden sign indicating the height measuring point with a sword, and slapped it in half vertically with his bare hand.

"Jin Zha, you are responsible for carrying your younger brother, and don't worry about anything else.

Miss Hu, Miss Yin, you are in charge of stabilizing these two boards.

There are four people left, the Xu brothers are in a group, and Tangun and I are in a group.

The two groups took turns dragging the wooden board with a rope, ran with all their strength for a stick of incense, and changed to another group! "

At the critical moment, only an adventurer like Li Daoyuan who has traveled all over the world can have such quick wit.

The truth is not difficult to say, it is a sledge pulled by people, because the path to the top of Baishan has many cliffs that need to be climbed, so coolies such as dogs and horses cannot be brought up.

Li Daoyuan was able to obtain local materials in a hurry and deploy manpower reasonably, if he hadn't had the experience of surviving in outdoor dangers many times.

The Xu brothers were also polite, and immediately clasped their fists together and said,

"Okay, then let's go first!"

The two of them each cut off a few dead branches, tied two to the soles of their feet, and held two to their hands.

When the others finished packing up, the two put the rope on their shoulders, stretched out their arms vigorously, and started gliding at high speed on the snow field with the help of two dead branches on the soles of their feet like rowing a boat.

Such a single-person sledge is an essential skill for Baishan tribe scouts.

If the Xu brothers hadn't wanted to take care of the large army, they would have wanted to use this method a long time ago.

The two brothers moved like tigers, and their forward speed was no less than that of a healthy dog.

The hail and rain became denser and denser, and the people on the board hugged each other tightly.

In order to stabilize the center of gravity and the distance between the two sleds, Hu Caiting and Yin Seke straddled their horses very low.

Brother Jinzha was protected in the middle. Qingyun took off his fur cloak and signaled Li Daoyuan to spread it over his head to protect everyone from the hail and rain.

But the Xu brothers didn't have such good treatment. In order to move forward at full speed, they used both hands to support the pole, and had no time to protect themselves.

Fortunately, Master Li Hou reminded them to put hard objects on their heads for some basic protection.

But on the body and legs, the black and blue patches were smashed out, it was hard to count.

It was less than a stick of incense, and the two of them couldn't take it anymore, so they were replaced by the next group.

This kind of single-person sledge was unfamiliar to both Li Daoyuan and Qingyun.

Fortunately, one has rich experience and has practiced countless strange methods in all walks of life, and the other has superb martial arts, especially his footwork.

With a little adjustment between the two, they can control it proficiently.

Although their speed was not as fast as the Xu brothers', their stamina was much better, and they ran for two or three sticks of incense in one breath.

The huge puff of smoke, like a Ragnar exorcist, has turned into a soaring smoke column, and the top cannot be seen.

The air was filled with the smell of sulfur, and everyone had to take some necessary filtering measures.

When Wudou Midao set up the blood mist formation, he had used the filter device of Mole's Nose, and the current conditions were simple, but Qing Yun also knew how to poke the wine sac and stuff some wormwood to achieve a similar effect.

But in this way, they are tantamount to breaking the boat and betting everything.

Wangshan ran dead horse, although the dust pillar seemed to be in front of his eyes, but it would take a lot of time to really climb to the top.

Another piece of hailstone hit Li Houye's knee, and he roared and fell to the ground.

The Xu brothers rushed over to change shifts.

But not long after he left, his elder brother also collapsed, so he had to be the younger brother of the Xu family and Qing Yun to regroup.

The hail and rain were merciless, and the brothers of the Xu family couldn't support them for too long.

Hu Caiting and Yin Se could see that Qingyun's physical strength was also a bit exhausted, so they took the initiative to go up to take over.

At this time, Qingyun was not polite to them, he just talked about how to operate the single-person sledge, and then withdrew to the board to lift the fur for everyone.

When everyone was exhausted and bruised, the snow field finally came to an end.

There is an obvious depression on the top of the mountain, from which the smoke and dust spewed out.

The temperature in the center of the smoke and dust is extremely high, as if the field of vision has been melted and slightly distorted.

The hailstones were all burned up in the air and never fell to the ground.

Those who were melted by the terrifying high temperature were far more than these. Rocks and ore veins from the depths of the stratum, various embers of complex composition permeated the air, emitting a pungent smell, making it impossible for people to move forward.

"Is it really possible to live around here?"

Qingyun hesitated.

"Come with us!"

The Xu brothers limped ahead and led the way.

There was another muffled sound from the crater on the top of the mountain, and the whole Dabai Mountain was shaken.

Probably the nearby rocks have been baked until soft, and the foundation is also a little loose.

This time the huge earthquake actually caused a large-scale landslide, and the whole mountain suddenly tilted down towards the crater.

Brother Xu's leg had already been injured, but at this moment his foot suddenly went limp, he couldn't stand still for a moment, fell down with a thud, and rolled towards the center of the crater along with the sunken mountain.

The younger brother rushed forward to fish it, but he almost fell down. If he hadn't been supported by Lord Li, he might have followed in his brother's footsteps.

Qingyun hastily pulled off the rope on the pry board, shouted "Catch!", and threw the end of the rope out.

The long rope was thrown into the air, as if there was a violent friction with the air, and thousands of sparks were rubbed out.

The rope at the far end gave off a burnt smell, as if it was about to be ignited.

Brother Xu's beard, hair, and fur coat also started to catch fire, and his body was probably scalded, but his last survival instinct made him burst out with enormous energy.

He jumped up, grabbed the long rope, used his strength to roll over, and tied the rope tightly to himself.

Between life and death, this is the only correct choice.

The long rope spread out like a long-term rot, turning into a little bit of fire butterfly,
But fortunately, Xu's elder brother rolled quickly, and there were still some strong tendons wrapped around his body.

Mars gnawed away at the grass ropes and clothes like moths.

Qingyun pulled out his hands repeatedly, and pulled Xu's elder brother back before the whole long rope disintegrated.

Bang, brother Xu's body fell heavily to the ground, and was grabbed by Master Li and his younger brother.

My brother's face was scorched black, his throat seemed to be smoking, and he couldn't make a sound.

Lord Li Hou sighed, "I'll support him, my brother will lead the way, let's get out of here quickly!"

The whole group left with each other supporting each other, Hu Caiting and Yin Seke were at the end of the line.

The crater was still raging, roaring intermittently.

wow la la la~
Another large landslide.

Qingyun heard the voice coming from behind, so he quickly turned his head to look.

"No!"

Following his lung-piercing roar, Hu Caiting and Yin Seke swayed in the dust and slipped one after another.

As God's will tricks people, the two girls slipped in different directions and gradually drifted away.

Even if he Qingyun has the ability to reach the sky, he must make a decision immediately.

(Hahaha, learn to be a broken dog!)
"""""Knock on the blackboard time"""""

There are quite a few things to talk about in this section, so let’s take it a little at a time, hoping that the amount will be enough, and we can chew it thoroughly.

At the beginning of this chapter, Du Hui saw an indescribable existence, which looked like a god of death.Since this article is a serious historical article, why play ghosts?It is precisely because of seriousness that we should be in awe of the unknown.Overcoming the fear of life and death is the essential issue that this small plot wants to explore.What exactly did Du Hui see? As a character with an independent ending, we may not get the answer until the end of the novel. At that time, we will be able to read a more bizarre story recorded in an ancient book.

And Du Hui, which has appeared in this article so far, also has its prototype.His real name is Du Wu. See "Taiping Guangji Dao Shu II", it is said that Du Wu, the official to the Shangshu, once got medicine from the immortals in Changbai Mountain when he was not developed, and his face was not old.Shangshu is not a petty official, and the author will put aside the details here and wait until the episode.

Next we're going to talk about Lawrence.As mentioned earlier, they were originally Uyghur Northeast Yi, with the Han surname Xiao, which was the well-known Xiao family in the Daliao period.This is not over yet, the Shulu family joined the gold after the death of the Liao Dynasty and changed its name to the Shimo family, which is also a prominent family.Later, the Jurchens rose up, and they were called the Shu Mulu clan, and they became one of the oldest tribes of the Jurchens.Shu Mulu's clan branch, Sinicization changed the surname to Shu, Xu.It sounds quite casual, and it seems that it has nothing to do with the Xiao family back then, right... Big mistake!Xiao, Shu, and Xu are all surnames derived from the surname Ying. During the Spring and Autumn Period, Xiao State was adjacent to Peng State (now Pengcheng), and was annexed by Xu State. However, with the rise of Song State, it became a vassal of Song State.And "Spring and Autumn" also records that Shu State died in Xu State, rose from Chu, and reattached to Chu.But all three surnames share a common origin.From the Liao Dynasty to the Qing Dynasty, a hundred years later, the sinicized surnames of this family can maintain such a mysterious connection. Is it a coincidence, or... You know, although there are many surnames derived from the Ying surname, they are not as good as Ji Jiang after all. Pick three at random The surnames are all descendants of the Ying surname, the probability of this is really slim.This section mentions here, in fact, just to explain one of the key historical concepts emphasized in this book, that there is no barbarian side in China, and the four seas share one family.The distinction between Hua and Yi is a Confucian interpretation based on the regional structure.But from the perspective of true blood ethnology, no matter the barbarians, the barbarians, the barbarians, or the rong, they are all descendants of the three emperors and five emperors and the eight surnames in ancient times.

The same is true for the four mountains. Therefore, the Yue family entered the Central Plains in the Song Dynasty and was also a descendant of the Huaxia clan.But why not Liaojin?

Siyue's Sishan technique seems to be a bit of a black technology.There are some, but it is not an exaggeration.First of all, the instruments for determining the longitude and latitude first appeared in China in history, and the international academic community does not seem to have much disagreement about this point.The theodolite divides longitude and latitude into scales, which proves that the ancients had a comprehensive and profound understanding of the earth's circle.Yes, no doubt!
The round sky and the earth are Confucian concepts, while hanging like chicken eggs is advocated by Taoism. There has never been a distinction between these two concepts in ancient times, because scientific instruments such as armillary spheres, theodolites, etc. fully illustrate the philosophical status of the theory of round earth in ancient China.From "Lunheng", "Laozi Heshang Gongzhangju", "Sanwu Lizheng", "Hanshu", "Suishu", "Huainanzi", "Baopuzi", "Yunji Qizhu", "Shi Shuo Xin Yu and so on, etc., all of these books have expressions of the theory of the circle of the earth.In the previous article, we said that the round sky is used to measure the earth, and the longitude and latitude of the sky are used to measure the sky. This is exactly what the ancients did.

The round sky and the earth are definitely not dross. He made ancient Chinese map drawing stand out.We have already exaggerated the ancient Chinese cartography in the previous article, but we only made a comparison of the timelines, and have not carefully explained how far the ancient Chinese surveying and mapping has been approved.

As a practical application of a round sky and a square place, planing squares was first proposed by Pei Xiu, a cartographer during the Three Kingdoms period.The so-called mile drawing square is to convert the actual measured mileage into a fixed-sized square on the map, which is now the so-called scale.The map drawn in this way is infinitely close to modern drawing.The "Topography and Abbot Map" drawn by Pei Xiu with one inch as a hundred miles has been lost, and the earliest square map handed down is the Southern Song Dynasty stone carving "Yuji Map" (see Easter Egg Chapter).

It is an indisputable fact that "Yuji Tu" surpassed Western cartography for hundreds of years.

The compass is an essential tool for field surveys and has a very long history. "Children Learning Qionglin": Zhou Gong made the compass car, and the compass is his legacy.Tells about the origin of the compass.The compass made in Han Dynasty is not as complicated as the compass made in Qing Dynasty, and it is mainly used to mark the direction.In ancient times, the correction of the compass was indeed done by turning around the mountain on the spot.

As for the Yue Wang Zhong, it is a product with a bit of black technology.Similar to the current altimeter.

The key principle of the altimeter is to measure air pressure. There are many ways to measure air pressure now, and the native method of water column and mercury column will definitely not be used.Wait, wasn't the Torricelli experiment that proved the atmospheric pressure for the first time done by the Italians in 1643?
Will the West teach you with ancient Chinese books?
As early as the Spring and Autumn Period, "Guan Yinzi" has already described the concept that atmospheric pressure can push up a water column.Guan Yinzi said: There are two orifices in a bottle, fill them with water, if one is poured and closed, the water will not go down.

In fact, it is also mentioned in the "Huangdi Neijing", but the words are not detailed and will not be quoted as evidence.

The phenomenon of atmospheric pressure is mentioned here, but the height of the water column that atmospheric pressure can lift is not mentioned.Don't worry, people in the Tang Dynasty had more accurate experiments.This experiment is similar to the Ji Zaixing siphon we mentioned earlier to build a water wall.In this operation, the water is directed upwards, how to do it? "Tong Dian" says: Take water from the mountains, connect the male and female in large bamboo tubes, do not let it leak, seal it with hemp paint, push it over the mountain, put the water in the tube, enter the water five feet, that is, at the end of the tube, take pine birch hay, When the tube is set on fire, the fire gas will dive into the water, and it will go up.

What do you mean?It is to connect the pipes so that there is no air leakage, and then heat it next to the cylinder (reduce the air pressure), and the water will naturally be sucked up. This method can divert water over mountains.

The maximum altitude allowed for one operation is actually atmospheric pressure, 9.8 meters of water column.Since ancient times used this method to divert water and climb mountains, it must be used to the extreme.Therefore, it was feasible in ancient times to use this method to measure atmospheric pressure and then know the altitude.

Here are a few details.First of all, in extremely cold places, water will condense, so it is necessary to use high alcohol instead of water.Even if the standard atmospheric pressure is converted to mercury, it must be 76 centimeters high, so it is impossible for a small instrument to be completely weighed with liquid.Therefore, the liquid part of the device mainly plays the role of pressure transmission. Water, alcohol, and mercury are all good, and the key is the counterweight on the liquid surface.

As long as there is a hole at the top of this Yuewang Zhong, put the counterweight smeared with stone grease into it to discharge the air, then seal the hole, fill it with water (wine) and pour it into the sink.Since the stone grease prevents the anti-leakage of water, the counterweight can only be pushed on the water surface, and the simple air pressure device is ready.As long as the corresponding scale has been calibrated at different heights, it can be used for rechecking next time.

Finally, the author added a little easter egg.What is Ragnar Nuo Master?This is a meme that shows its age.This stalk is really related to volcanoes, lava, and sword casting... Because of a coincidence, the author randomly incorporated it into the article.
