She paused and continued: "It is also because there are many natural magnets here, which also made the court's master choose this place as the concubine's concubine. ”

"Of course." She looked at everyone: "At the moment, we can only guess that this is the case, if we want to verify my guess, we only need to look at the control. ”

After that, she looked at the many painting boats that were constantly cruising in the outer mercury canal: "Looking at it now, most of these painting boats can keep cruising, most of them are also related to magnetism, we only need to intercept the next painting boat, and we can probably verify what I said." ”

It was a matter of the mystery of the coffin hanging in the air, Yue Guanchao and the others packed up all kinds of utensils hanging in the air and returned to the Huangquan Bridge.

He and several guards pulled up the rope, grabbed a boat that was cruising directly, and after fixing the rope to the railing, the boat immediately stopped in place.

Walking to the canal, they lifted the beaded curtains around the pavilion of the painting boat, and in the cabin were stone figurines kneeling in front of and behind the square table, similar in shape to terracotta figurines, looking like two stone dummies.

Look closely, the stone statue is about half a person high, kneeling like a fat boy, the clothes and clothes are very real, the eyebrows, eyes, mouth and nose are vivid and detailed, and the whole body is like carbon black, like a charred living person.

Song Siyuan picked up an iron shovel, and after approaching the stone man, she could really see that the iron shovel was adsorbed on it, and it took a lot of strength to get rid of the magnetic adsorption.

"In this way, let's turn the boat in a different direction and see how the other ships react."

Yue Guanchao grabbed the hull of the boat, swapped the bow and stern back and forth, and after parallel to the river, behind the captured boat, some painting boats began to be repelled by an invisible force, and they could never get close.

Song Siyuan observed the current situation, and her eyes lit up: "That's right, the stone statues in these paintings are magnets, representing the positive and negative poles respectively, when we flip the bow of the boat, the two bows of the same sex are repulsive, and they can only be pushed away by each other." ”

"When we turn the bow of the ship in the opposite direction, even if the positive and negative poles of the bow return to normal, under the different magnetic forces of the burial platform and the caisson well, the positive and negative electrodes are constantly pulled by the positive and negative electrodes, so that the hull of the ship is captured by the magnetic force and rotates around the burial table, and it looks like the ship is floating on a pool of mercury."

Speaking of this, her eyes lit up: "Just now, I always thought that these painting boats were actually driven by some mechanism gears under the hull to rotate, but now I look at it, it is actually more exquisite than I thought, and it can make the painting boat flow for thousands of years without the power of any mechanism." ”

Yue Guanchao thought it was her random speculation just now, but seeing that the magnetic attraction came true, a bigger question followed: "But this thing is too advanced, you just said, four years ago, German engineers first discovered the principle of electromagnetic levitation, and applied for what patent they made, it was at least eight hundred years from now, did the ancients know what electromagnetic induction principle at that time?" ”

"I can't be sure of that, but don't underestimate the wisdom of the ancients."

Speaking of this, her eyes lit up: "The ancients just lacked knowledge, but that doesn't mean they weren't smart, especially in ancient dynasties, some craftsmen may inadvertently discover some new application techniques, although they are limited by knowledge and can't know what the principles are, at least it is okay to apply them with experience." ”

After a pause, she continued: "For example, the oil used in our cars today was probably discovered by travelers in the Han Dynasty to name it stone paint, which means paint as black as a stone. ”

"From the Han Dynasty to the Tang Dynasty, the ancients have deepened the record of stone paint, and even have begun to be applied to lighting, ink making, and disease treatment, "Dayuan One Unification Chronicle" records, Yanchang County South Yinghe, there is a well of oil drilling, its oil is combustible, and the treatment of six animal scabies, in the Song Dynasty before the Yuan Dynasty, has been used to use bamboo tubes, drill bits, long bamboo poles to penetrate the formation, chisel stone paint, formed a set of tools that can be used."

"However, it is Western scientists who really make full use of the role of oil."

"And that's not all." Song Siyuan continued to explain: "You know that Zheng He went to the West. ”

Yue Erpao nodded, he went to see the Western scenery, and his favorite thing was the story of Zheng He's trip to the West.

In the past, Zheng He was ordered by the Yongle Emperor to drive 200 large and small huge ships to the ocean, called to find foreign civilizations, but in fact it was the little emperor Jianwen who disappeared in the search for Jingjing, Zheng He went to the West seven times, and traveled countless Western foreign states along the way, and the tributary trade made the foreign countries know the wealth of Zhu Ming, and also spread the national prestige of the Ming Dynasty overseas.

"Don't you wonder why Zheng He was able to sail to the vicinity of the Cape of Good Hope in present-day South Africa with a wooden boat?"

Song Siyuan didn't want to sell Guan Zi either, and continued: "According to historical records, his ship was probably equipped with a steam boiler, and it was the development of this steam boiler and watertight cabin technology that allowed Zheng He's hundreds of fleets to sail smoothly several times, making the Western countries regard Zhu Ming as the superior kingdom of the Celestial Empire. ”

"This kind of steam boiler is actually the first industrial innovation of steam engine technology, but when Zheng He applied the principle of steam work, it was in 1405 AD, and the appearance of Western steam engine technology was in 1776, nearly 400 years later than Zhu Ming."

Yue Guanchao had already figured out the meaning of his words, and continued to ask: "Since Zheng He has discovered the steam engine technology, why is there no shadow after that!" ”

"That's the important message I'm going to say."

Song Siyuan looked at everyone: "The wisdom of the ancients cannot be underestimated, and the new application technologies they have discovered are much more than we understand today, but most of the technologies are only in the stage of empirical application, and because there is no scientific thought and overall discipline, they are often distributed in a single piece, rather than systematized......

It's like a boat, the ancients only knew that the boat could float on the water, and they also knew how to make a faster and bigger boat, but they never delved into the effects of buoyancy, gravity, drag, wind, and water speed on the boat.

It is equivalent to saying that all the knowledge of the ancients is scattered and unsystematic, without in-depth study of principles and underlying logic, and often relies on experience to pass on to future generations.

It's a pity that experience is like a folk remedy, with the change of dynasty, war and migration, and the inheritance of offspring, experience is constantly lost, and even the details are distorted, and in the end, the difference is thousands of miles, and it is basically an abandoned experience.

Back then, as early as the Tang Dynasty, the ancients studied the technology of iron, this thing is now high-quality steel, the Tang Dynasty long-handled Mo knife made of iron, but where you can take it in your hand, you can fight a hundred, the blade is broken everywhere, it is extremely sharp, it can be said that it is the first knife in the medieval world.

Wang Zhonghe, a general of the Tang Dynasty, once led the soldiers of Hexi to attack some small countries in the Western Regions, but when the Hu people saw the Tang army holding a Mo knife, they would definitely tremble like chaff and surrender the city.

This powerful knife forging technology has been lost in the Song Dynasty, the Song people believe that the iron is the weapon of the gods, made of the poop pulled by the divine beast unicorn, it can be seen that if there is no systematic discipline and application principle, the circulation of experience will be greatly wrong and distorted!

After the previous dynasty entered the customs, in order to ensure that the Manchus ruled the Han people, they directly closed the country, and the coastal plates were not down to the sea, Kandi had always communicated with the Westerners, and also knew that the earth was round, and the Qiandi was very good at mathematics, and also knew that the Westerners were engaged in industrial innovation at the same time.

The upper rulers of the previous dynasty never minded scientific knowledge, but were willing to learn it, and they were afraid that the people at the bottom had mastered scientific knowledge and threatened their rule.

In order to fool the people into ruling the Han people, they deprecated all science and technology as strange and ingenious skills, only let the scholars study the ancient books and scriptures, and let the peasants and laborers work hard all day but could not fill their stomachs, thus bringing about the most feudal and oppressive world.

Their obstruction to science was so deep that until the end of the previous dynasty, many people heard for the first time that the earth was round, and they were still shocked, and almost all of the wisdom of the upper and lower five thousand years was deliberately destroyed by the previous dynasty.

Song Siyuan said this and took a deep breath: "Although I am surprised to find the application of magnetic force here, I don't think it is ridiculous, after all, the ancients in the Sui, Tang, Zhao and Song dynasties were very smart, and if they really perceived the application of magnetic force, it would be reasonable." ”

Song Siyuan's words from the past to the present made everyone stunned, and Sun Daqiao praised him: "Wonderful, wonderful, there are some things that we still can't see clearly in this mountain, and only a scholar like you can see the truth." ”

Sun Tianqi listened to her words, and couldn't help but appreciate it for a while, and asked: "If this is the principle of magnetism, then, how can we go up, we can't fly, anything metal will be captured, I'm afraid it will be difficult to fix the grappling hook on the coffin with a bow and arrow." ”

"Use heat!"

"With heat?"

The crowd was curious about this statement.

Song Siyuan explained: "I have read a report in the Science Labor Daily, this electromagnetic levitation technology, need to keep the absolute cold of the magnet, I guess that heat will destroy the magnetic force, high heat is likely to make the magnetic force directly fail, the ancients probably also knew this, it is mercury used to cool the tomb." ”

"The whole tomb is built on water, probably also has the meaning of cooling, mercury is an inert liquid metal, although it will volatilize at room temperature, but compared to the evaporation of water, it is almost negligible, the flowing mercury takes away the heat to reduce the temperature, and also makes the tomb always cold, we feel the coolness, most of the mercury cooling, this low temperature in disguise supports the stability of mercury, so as to cause thousands of years of magnetic force is not damaged."

"Since high heat will destroy magnetism, then we might as well heat the things we use to a high temperature first, and fix them on the caisson with a bow and arrow before the temperature drops, so that we may be able to avoid magnetic interference as much as possible, of course, this principle has only been proposed for four years, and I am just guessing."

"What do you think?"

Song Siyuan would only say what she meant, or she still wanted them to make a decision, Yue Guanchao nodded at her and said approvingly: "You can explain what happened thousands of years ago, how can we have this ability, it must be like this, or we will just roast the metal claws and use a bow and arrow to pierce them directly into the caisson, and when it cools down, we will climb to the coffin along the rope and open the coffin first." ”

Some people died, but not completely......
