She paused and continued: "It is also because there are many natural magnets here that Master Chao Feng chose this place as the tomb of the concubine."
"Of course." She looked at everyone: "At present, we can only guess that this is the case. If you want to verify my guess, you only need to observe the control object."
After that, she looked at the many painted boats that were constantly cruising in the peripheral mercury canal: "Looking at it now, these painted boats can continue to patrol, which is probably related to magnetism. As long as we intercept the next painted boat, we can probably verify what I said."
Regarding the mystery of the hanging coffin, Yue Guanchao and the others packed up the various hanging utensils and returned to the Huangquan Bridge.
He and several nurses pulled up the rope and directly grabbed a cruising boat. After fixing the rope on the railing, the boat immediately stopped in place.
When they walked to the water channel, they opened the beaded curtains around the pavilion. In the cabin, there were stone figurines kneeling in front of and behind a square table. They were similar in shape to pottery figurines and looked like two stone dummies.
If you look carefully, you will see that the stone statue is about half a person tall, and it looks like a fat boy sitting on its knees. Its clothes and accessories are very realistic, its eyebrows, eyes, mouth and nose are vivid and detailed, and its whole body is as black as charcoal, like a burnt living person.
Song Siyuan picked up a shovel and approached the stone man. As expected, she could see that the shovel was attracted to it. It took a lot of effort to break away from the magnetic attraction. She then tried it again on the opposite side, and it was indeed able to be attracted.
"In this way, we will change the direction of the ship and see how other ships react."
Yue Guanchao and the others grabbed the hull of the boat and switched the bow and stern back and forth. After the boat was parallel to the river, some boats behind the captured boat began to be repelled by an invisible force and could never get closer.
Song Siyuan observed the current situation and her eyes lit up: "That's right. The stone statues in these boats are magnets, representing the positive and negative poles respectively. When we turn the bows over, the two bows will repel each other, so we can only Being pushed away from each other.”
"When we turned the bow around, the positive and negative poles on the bow returned to normal. Under the different magnetic forces of the burial platform and the caisson, the positive and negative poles were continuously pulled by the positive and negative poles, causing the hull to be captured by the magnetic force and revolve around it. The burial platform rotates and looks like a ship floating on a pool of mercury."
When she said this, her eyes lit up: "Just now, I had always thought that these boats were actually rotated by some mechanism gears under the hull. Looking at it now, it turned out to be more sophisticated than I thought and did not require any mechanism. Its power can also make the boat circulate for thousands of years."
Yue Guanchao just thought it was her random guess. Seeing that the magnetic attraction theory came true, a bigger question followed: "But this thing is too advanced. As you just said, German engineers first discovered electromagnetic levitation four years ago. Principles, and what kind of patents were applied for them? It was at least 800 years ago. Did the ancients know the principle of electromagnetic induction at that time?"
"I'm not sure about this, but don't underestimate the wisdom of the ancients."
Speaking of this, her eyes lit up: "The ancients just lacked knowledge, but it does not mean that they were not smart, especially in the ancient dynasties. Some craftsmen may inadvertently discover some new application technology, even though they are limited by knowledge, It’s impossible to know what the principle is, but at least it’s OK to apply it based on experience.”
She paused and continued to explain: "For example, the oil used in our current cars was probably discovered by travelers during the Han Dynasty and named Shiqi, which means paint as black as stone."
"From the Han Dynasty to the Tang Dynasty, the ancients' records on stone lacquer continued to deepen, and it even began to be used for lighting, ink making, and treating diseases. "Dayuan Yitongzhi" records that there was an oil well dug in the south of Yanchang County. , its oil is flammable and can also cure scabies in livestock. In the Song Dynasty before the Yuan Dynasty, bamboo tubes, drill bits, and long bamboo poles were used to penetrate the ground and dig out stone paint, forming a set of tools that can be used."
"However, it was Western scientists who really made full use of the role of oil."
"That's not all." Song Siyuan continued to explain: "You know Zheng He's voyages to the West."
Yue Erpao nodded. He went to see the Western scenery. His favorite was the story of Zheng He's voyages to the West.
In the past, Zheng He, under the orders of Emperor Yongle, sailed 200 large and small ships to the oceans. The name was to search for foreign civilizations, but in fact, he was searching for the little emperor Jianwen who disappeared during the Battle of Jingnan. Zheng He made seven voyages to the Western Ocean, walking all the way. Countless Western foreign countries and tribute trade made foreign countries aware of Zhu Ming's wealth, and also spread the Ming Dynasty's national prestige overseas.
"Aren't you curious as to why Zheng He was able to sail to what is now the Cape of Good Hope in South Africa with a wooden boat?"
Song Siyuan didn't want to sell it off, and continued: "Historical records show that his ship was probably equipped with a steam boiler. 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 All Western countries regard Zhu Ming as the supreme kingdom of heaven."
"This kind of steam boiler is actually the steam engine technology of the first industrial innovation. However, Zheng He applied the principle of steam power in 1405 AD, while Western steam engine technology appeared in 1776, which was completely later than Zhu Ming. Nearly four hundred years.”
Yue Guanchao had already figured out the meaning of his words and continued to ask: "Since Zheng He discovered steam engine technology, why has there been no trace of him since then?"
"That's my big message."
Song Siyuan looked at everyone: "The wisdom of the ancients cannot be underestimated. The new application technologies they discovered are much more than what we understand today. However, most technologies only stay in the stage of empirical application. Due to the lack of scientific thinking and Coordinating disciplines are often distributed in a single piece rather than in a systematic manner..."
This is like a ship. The ancients only knew that the ship would float on the water, and they also knew how to make a faster and bigger ship, but they never delved into the effects of buoyancy, gravity, resistance, wind force, and water speed on the ship.
In other words, all the knowledge of the ancients was fragmented and unsystematic. There was no in-depth study of the principles and underlying logic, and they often relied on experience to be passed down to future generations.
It is a pity that experience is like folk remedies. With the changing dynasties, wars and migrations, and the inheritance from generation to generation, experience is constantly lost, and even the details are distorted. In the end, when it is passed down, the difference is thousands of miles away, and it is basically classified as being passed down. Abandoned experience.
Back then, as early as the Tang Dynasty, the ancients had developed the technology of iron and iron, which is now high-quality steel. The long-handled Mo Dao of the Tang Dynasty made of iron and iron can defeat a hundred people in one hand. Wherever the blade touches, people and horses can be defeated. It is both broken and extremely sharp. It can be said that it is the best knife in the medieval world.
Wang Zhongsi, the general of the Tang Dynasty, once led Hexi soldiers to conquer some small countries in the Western Regions. Whenever the Hu people saw the Tang army holding Mo Dao, they would tremble like chaff and surrender in the city.
This powerful knife forging technology had been lost by the Song Dynasty. People in the Song Dynasty believed that iron iron was a weapon of the gods, made from the cakes pulled by the mythical beast Qilin. It can be seen that without systematic disciplines and application principles, the spread of experience would be extremely difficult. Big fallacy and distortion!
After the previous dynasty entered the Pass, in order to ensure that the Manchus ruled the Han people, they closed the country directly and prevented coastal areas from entering the sea. Emperor Kangdi had been communicating with Westerners and knew that the earth was round. Emperor Kangxi was very good at mathematics and also knew about the contemporaries. The West was engaged in industrial innovation.
The upper-class rulers of the previous dynasty never cared about scientific knowledge, but were willing to learn it. What they were taboo about was that the people at the bottom mastered scientific knowledge and threatened their rule.
In order to fool the people and rule the Han people, they denounced all science and technology as strange and obscene skills, and only let the scholars study ancient books and scriptures, and let the farmers and workers work hard all day long without enough to fill their stomachs, which brought about the most feudal and oppressive world.
Their obstruction of science was so deep that until the end of the previous dynasty, many people were still shocked when they heard that the earth was round for the first time. Almost all the wisdom of 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 magnetism here, I don't think it is ridiculous. After all, the ancients in the Sui, Tang, Zhao and Song Dynasties were very smart. If they really noticed the magnetism and applied it, , which makes sense.”
Song Siyuan's reasoning from ancient times to the present made everyone dumbfounded. Sun Daqiao praised him and said: "Wonderful, wonderful, there are some things that we still can't see clearly in this mountain. Only a knowledgeable person like you can See the truth.”
Sun Tianqi couldn't help but feel admiration after hearing her words, and asked: "If this is the principle of magnetism, then how do we get up? We can't fly. Any metal object will be captured. I'm afraid it will be difficult to use a bow and arrow to grab the grappling hook." Fasten it to the coffin."
"Use heat!"
"Use heat?"
Everyone was very curious about this statement.
Song Siyuan explained: "I have read a report in the Science Labor News. This electromagnetic levitation technology requires keeping the magnet absolutely cold. I guess heat will destroy the magnetism. High heat is likely to cause the magnetism to directly fail. The ancients probably also knew this. It was mercury that was used to cool the tomb chamber.”
"The whole tomb is built on water, which probably means cooling down. Mercury is an inert liquid metal. Although it will volatilize at room temperature, it is almost negligible compared to the evaporation of water. The flowing mercury takes away heat and lowers the temperature. The tomb is always cold, and the coolness we feel is mostly due to the cooling of the mercury. This low temperature supports the stability of the mercury in a disguised form, thus maintaining the magnetic force for thousands of years."
"Since high heat will destroy magnetism, we might as well heat the thing to high temperature first, and use bows and arrows to fix it on the caisson before the temperature drops. In this way, we may be able to avoid magnetic interference as much as possible. Of course, this kind of The principle was proposed only four years ago, so I’m just guessing.”
"What do you think?"
Song Siyuan would only tell her what she meant, but she still wanted them to make a decision. Yue Guanchao nodded to her and said in approval: "You can explain things that happened a thousand years ago. How can we not have this ability? This must be what happened. How about we do it?" After heating the metal claws, use a bow and arrow to pierce it directly into the caisson. While it is cooling, climb up the rope to the coffin and open the coffin first."
Some people died, but not completely...
