Most of the people present were old men, and their bodies were relatively weak, so they didn't dare to get too close to the ice coffin. Professor Fang asked people to use a camera to zoom in on the text on the stele, and everyone read it on the computer.

The more Kong Lao and the others looked, the more they were surprised, this was actually Cao Cao's real tomb, and the most fake tombs in history were placed by this person. Everyone recalled the previous situation and found that Cao Cao was implicated in many places.

"I didn't expect that! He actually set up his own tomb under another emperor and used others as a shield. Yan Lao said.

"It's a pity! Or was discovered. He left too many hand tails, it is difficult not to make people suspicious, the so-called smart is mistaken by cleverness! Xu Lao smiled.

Kong Lao nodded: "No wonder you can take out Hua Tuo's relics and lay down so many traps." I really didn't expect that this person was even more terrifying than recorded in the history books, and he actually hid so many treasures. It's a pity that he couldn't crack the contents of the Book of Heaven, otherwise the Three Kingdoms might be unified under his conquest. ”

"What is the origin of the ice in this ice coffin, after a thousand years, it still emits such a strong chill, and there is no trace of melting. And those eight headlights, when did they start burning, what is the fuel in them, and how long can they burn? Li Lao frowned.

These words made everyone ponder, the character of Cao Cao is really amazing, and he can leave so many mysteries to future generations after death. Especially the ice coffin, such an example is definitely the first time in ancient and modern times. I often hear the lamp that never burns, but everyone has never seen a lamp that has really burned for thousands of years.

"I don't know the situation of the ice coffin, the fire is also weird, some like the ancient legend of the 10,000-year-old lamp, all blue. Just according to the legend description. This 10,000-year-old lantern is burned by extracting the grease of a mysterious creature in the East China Sea, and it is very resistant to burning, but it is said that there is only a wisp of blue flame, which is not that big. There is another possibility, and that is the everlasting light that everyone often hears. Kong Lao said.

Kong Lao said that the 10,000-year-old lamp is not well known. The ever-bright lamp is no stranger.

The ever-bright lantern, also known as the continuous lantern, or the endless lamp, is the lamp that is always bright day and night before the Buddha. Since ancient times, every household has lit a lamp on Chinese New Year's Eve. Once lit, it cannot be blown out until the oil is exhausted and the candle finally extinguishes itself, which is an ancient traditional custom. Everlasting lamps will also be placed in the tombs of the kings of the Middle Kingdom, hoping to be as brilliant as the palaces in their lifetimes.

The so-called ever-bright lanterns on the night of the folk Chinese New Year's Eve are not mentioned for the time being, that is, the ever-bright lanterns in the ancient tombs are not uncommon, and they can indeed burn for a long time. However, the length of the pole is also limited, and it is impossible to achieve the point of immortality for thousands of years.

According to the results of previous research, a kind of permanent lamp is a double-layer structure, and a container inside is filled with lamp oil, and the wick is soaked in vinegar. The outer layer is filled with water to cool the lamp oil; This is a great invention, because the oil consumed by the oil lamp is not mainly ignited, but volatilized by heat, and the wick soaked in vinegar is not easy to keep the temperature low, and the water outside the oil jar can also effectively prevent the oil temperature from rising. But Changming is an ideal wish after all.

In the excavation of the Dingling Tomb in the capital, there is a celadon vat in the main hall of the mausoleum, which contains wax lamp oil. There was also a wick, which was the Everbright Lamp, but apparently the lamp went out not long after the mausoleum was closed, due to the lack of air needed for burning in the closed mausoleum.

Not only in China, but also abroad There are many legends and discoveries about the ever-bright lantern.

There are grave robbers all over the world, and they want to do whatever it takes. Going to ancient tombs to steal gold, silver and jewelry that have been buried for thousands of years, ancient tombs are often isolated from the rest of the world. So that the treasure has been preserved quite well after thousands of years. In this ancient tomb that does not see the light of day all year round, tomb robbers usually think that they should not be able to reach out and lose their fingers. Sometimes, however, they were horrified to find that on the vaults of some tombs, a bright lamp cast a faint light. …,

During the Roman Empire in Western Europe, in Syria, Eastern Roman soldiers discovered a lamp lit in a pass alcove, which was covered by an elaborate hood, which seemed to be used to keep out the wind. According to the inscriptions found at the time, the lamp was lit in 27 AD. When the soldiers found it, the lamp had been burning for 500 years. Unfortunately, the savage soldiers quickly destroyed it, and the mechanism of this mysterious lamp is no longer known.

The never-extinguishing lamp is a natural topic of debate in academic circles. Some people believe that the records of the ever-bright lamp in various countries in the world are enough to make people affirm that there is indeed such a lamp that does not go out, or a lamp that burns for a long time, but the technology is lost, and our people can't understand it. Most of the people of insight in the Middle Ages believed that such an unextinguished lamp did exist, and that it had some kind of magical power.

Others believe that although there are so many records of the ever-bright lamp, in reality there is not a single ever-bright lamp in plain sight, and the energy problem of this lamp seriously violates the law of conservation of energy, so this kind of lamp that does not go out should not exist. There are also many who believe that this may be a clever joke made by the ancients in the book.

But in any case, the everlasting lantern has left a mysterious imprint in the hearts of the world.

As for the 10,000-year-old lamp in Kong Lao's mouth, in fact, he was very skeptical of the legend of the 10,000-year-old lamp, because the record had said that it was a kind of merman's grease at the bottom of the sea, and he didn't believe that there was really such a thing as a merman in this world.

"Tianbao, what do you think?" Kong Lao asked, after all, this guy always likes to delve into these bizarre and strange things, maybe he really knows.

Hong Tianbao pondered for a moment and said, "Judging from the flames alone, there is actually no problem, many of the flames are also blue. I have a guess, though, that it might be natural gas in it. And it's not the ever-bright light that everyone guesses.

First, if we look closely, we will see that the fuel inside is gas.

Second, there are actually a lot of gaseous fuels that we are more common, but in the natural state, it is natural gas.

Third, we may all be guessing when these eight lamps started burning. If I'm not mistaken, they do burn for thousands of years. It is very likely that there is a natural gas field below, and Cao Cao directly came up to ignite it.

If we look at it objectively, the construction here is really breathtaking, the ventilation system is so well done, eight large flames are burning together, and the oxygen is still available. And if it's like I'm guessing, the drying technology here is also very good, after all, natural gas burns, and water vapor is generated. ”

Hearing such an insight, everyone was shocked again.

"Was the gas discovered at that time?" A young man said.

"It's not surprising! Oil was discovered in the Han Dynasty in China, and it was used to a certain extent, but it was not used on a large scale. Professor Fang said.

Professor Fang's words are well-founded, natural gas and oil have been recorded in classics for a long time.

Our people discovered and used oil for the earliest time in the world. When it began, according to the audit, it began more than 3,000 years ago at the latest.

The earliest record of the discovery of oil comes from the Book of Changes: "There is fire in Ze", "Fire on the fire and Ze on the bottom". Ze refers to lakes and ponds. "There is fire in the swamp" is a description of the phenomenon of oil vapor catching fire on the surface of lakes, ponds, and marshes. This book was compiled in the Western Zhou Dynasty, more than 3,000 years ago.

The earliest ancient book to understand the performance and record the origin of oil is the "Book of Han" written by the Eastern Han Dynasty writer and historian Ban Gu 1,900 years ago. Geography. The book reads: "Gaonu County has water that is combustible." Gaonu County refers to the area of Yan'an, Shaanxi Province, and Weishui is a tributary of the Yan River. The origin of the oil is clearly documented, and it is stated that oil is a water-like liquid that can be burned. ..., "Actually, why bother to speculate? Find someone down and identify the composition of the gas. I just think natural gas is the most likely. If there is a gas field down there, then we are actually very dangerous. Because the gas field itself is a bomb, if you are not careful, everyone will fall into disaster. Hong Tianbao said.

Kong Lao and the others nodded, and in this analysis, they were more willing to accept Hong Tianbao's point of view rather than the 10,000-year-old lantern in ancient legends.

Professor Fang also asked technicians to analyze the chemical composition of the gas. Everyone continued to look at the ice coffin: "What happened to the ice coffin?" And why is everything here going up? ”

Hong Tianbao smiled slightly: "Did you notice the top of this place at the exit above just now?" ”

Kong Lao and the others frowned, and someone shot a flashlight on it, but it was too high, and they didn't find anything. Professor Fang seemed to remember something, and said, "I was also strange at first! There seems to be some small hole in the top. ”

Hong Tianbao nodded: "Let's think about what is on it." ”

These words reminded everyone of the tomb above, which contained a large amount of mercury, and when they thought of this, everyone felt a chill all over their bodies, and this trick could not be described as poisonous.

"Whew! It's a good thing we didn't mess with anything here, otherwise ......," one expert couldn't go on.

Professor Fang glanced at Hong Tianbao and praised: "Not bad! Observe carefully. ”

"Aren't we really in danger? Below is something that will explode, and above is mercury that can be poisoned. A young lad exclaimed.

"So! Cao Cao is a person who does not leave any chance for tomb robbers. Hong Tianbao smiled.

He looked at the ice coffin and pretended to frown, "Have you ever heard of the Yin Cave?" ”

At this time, the old qualifications such as Kong Lao and Professor Fang woke up. The earth has yin and yang points, which is the concept of Feng Shui. It is said that the yin acupoints continuously produce yin qi, and the yin qi is extremely cold. But it doesn't seem to have the power to keep the ice from melting for thousands of years, right?

"If there is a yin cave under the ice coffin, it means that this is a place of absolute yin." Hong Tianbao continued.

Everyone can't say for sure about these questions, and Hong Tianbao has no convincing evidence, so everyone has to put it aside. Professor Fang asked people to take pictures of all the words on the stele for research.

Kong Lao, Yan Lao and the others watched those treasures, but they didn't dare to move. Professor Fang searched cautiously, hoping to find out the mechanism inside, and everyone didn't have to worry about it.
