John Hua nodded at them: "Okay, I also agree with what you said, I don't see that the time is too early today, so let's go back first, and we will set off for the snow mountain early tomorrow morning." ”

Yue Guanchao continued: "There is another matter, we have already helped you find out the direction of the snow mountain, where is my family now?" ”

"Please rest assured." John Hua waved his hand at them: "Your family is safe, already in the inn, since we have reached a deal, then I will definitely abide by the details of the deal, and you will be able to see him when you go back." ”

They collected their things and returned to the ancient city of Yasa, and when they returned to the inn, Yue Qingshan was already in the room.

"Old man, they didn't do anything to you, did they?" Yue Ercang asked with concern, although Yue Qingshan didn't seem to have any problems on the surface, he still had to ask.

"Hey, kid, I'm an old man, what can they do to me? It's nothing more than locking me up to eat and drink, and I guess they don't want my life either, otherwise there are so many opportunities on the way, and they wouldn't all be missed in vain, and they should threaten you with me. ”

He paused, and his eyes became strange: "Now that you can see me, it means that you have reached a deal, old man, I am more curious, what does he want to blackmail you to do?" ”

Yue Qingshan had been the shopkeeper of the Golden Rat Society, and he still had points for the rivers and lakes, and now that he could see these descendants, he already understood what kind of deal they had probably reached with John Hua.

Song Siyuan interjected: "They want me to help them find the mausoleum of Jieli Khan, and the approximate location of the mausoleum has been determined today, but the specific location has not yet been determined, and we plan to go to the snow mountain tomorrow." ”

"Do you have a clue then?" Yue Qingshan knew that the deal they reached was definitely not to provide such vague clues, but to really find the ancient tomb, and now it was the most dangerous to just have a clue.

Sun Daqiao sighed: "This difficulty is not small, the last time we looked for the Ancestral Vein Soul Palace, in fact, it was not our own credit, but the Tang family gave us a set of incisions, so that we could successfully find the location of the Soul Palace, and now, with our own hands, I am afraid it is difficult to find the tomb of Jieli Khan." ”

"Still."

Sun Daqiao's words changed: "Song Qianjin has one point, Yuan Tiangang and Li Chunfeng can calculate the major events in the next two thousand years, and they can definitely calculate that the mausoleum of Jieli Khan will be turned into frozen soil, and the old man is thinking that if Jieli Khan's mausoleum really wants to exist in the frozen soil, it will take more than half a star." ”

Yue Guanchao hugged the old man's neck and said, "Sun Daqiao, don't sell Guanzi, hurry up, I didn't get to the point." ”

Sun Daqiao trembled and said: "The permafrost snow mountain only exists in the snowy plateau, except for the snowy plateau, the frozen soil in most places is frozen in winter and spring, completely melted in summer and autumn, between the frozen thawing, the frozen soil will definitely be soaked with water, every winter and spring when the flowers bloom, there is a possibility of mudslides, from a high place directly down the slope, I am thinking, this situation is completely unfavorable to the mausoleum."

When building a mausoleum, it is often necessary to choose a place with excellent feng shui, and one of the factors is to find a stable earthwork environment or a rocky environment for the mausoleum, and to avoid swamps as much as possible in places with loose soil structure.

Because the loose soil structure is completely unable to support the structure of the tomb, it is possible that within a few years the soil will collapse due to the frozen soil layer, and the entire mausoleum will be destroyed directly.

When Yuan Tiangang and Li Chunfeng were looking for tombs, they should not deliberately look for peaks that would become frozen soil in the future, and if they safely placed the tombs under such peaks and soil layers, would it mean that they had solved the problem of thawing permafrost or collapsing soil?

To solve these two problems, the first way is to find permafrost, and the second way is to start from the material of the tomb.

Let's start with the first case!

If you want to find permafrost, this means that the frozen soil will not melt at all for 2,000 years, and it will not change at all, in this case, the hard frozen soil will add a lot of help to the solidity of the mausoleum, but such mausoleums often do not appear outside the snowy plateau.

The snow-capped mountains they see can only be regarded as seasonal snow-capped mountains, frozen in winter and spring and thawed in summer and autumn, from December to May every year there is a half-year freezing period, and after May, it will not completely thaw until November, and when this time period comes, summer and autumn will come.

The annual half-year freezing period and the half-year thawing period are equivalent to the permafrost thawing once a year and then freezing again, which is completely unsuitable for permafrost.

Song Siyuan also said that from the early years of the Tang Dynasty to the beginning of the previous dynasty, in the past two thousand years, the cold ice period and the warm period alternated, which also means that the frozen soil of these snow-capped mountains may have thawed, and then froze through the cold air, and so repeatedly thawed and frozen.

If they hadn't solved the problem of frozen soil, the mausoleum might not have existed at all, because the mausoleum had long been completely crushed and brittle in the collapse and melting of the frozen soil.

It is completely impossible to meet the conditions of permafrost, of course, it is impossible to be chosen by Yuan Tiangang and Li Chunfeng, but if the process is reversed by the result, they can choose to build tombs here, which shows that it is very likely to achieve the second situation - that is, to solve the problem of thawing permafrost, give the tombs a more stable structure, and ensure that these tombs will not be harmed by the collapse of the soil even if they have experienced thousands of years of permafrost thawing and freezing.

Speaking of this, everyone became curious, and Song Siyuan asked, "Can this kind of problem be solved?" Or, to put it another way, will they be able to find a mausoleum structure that can stabilize even if the permafrost melts? ”

Sun Daqiao obviously knew how to do it, lowered his voice and nodded, his face became more and more mysterious: "When I was walking the rivers and lakes, I also saw some Mongolian merchants from the grassland, the more you go north, the more you can touch the thawed and solidified frozen soil, and even the good soil layer will become frozen soil after three or five years of ice, snow, wind and frost, and once it melts, it is destined to become wet mud." ”

The grassland people could not distinguish when the frozen soil appeared and when it melted, and gradually developed hanging pile burials for the frozen soil according to local conditions!

This kind of hanging pile burial needs to dig a deep pit when the frozen soil is hard, and then use wood to build a huge square burial chamber, and before this burial chamber is put into the burial pit, many wooden piles more than ten meters long need to be inserted on the four sides of the burial chamber.

The stakes are arranged like combs and are completely fastened to the outside of the tomb with angle irons, making them look like huge wooden boxes covered in thorns.

Then the burial chamber is completely sunk into the burial pit, and at this point it is already time to seal the soil, and the frozen soil that has been dug out will be completely melted by the baking oven, and then after melting, pour in glutinous rice syrup and stir evenly, and pour it completely into the wooden pit before it is completely solidified.

After a day or two, the soil will become very hard after it has completely solidified, and they themselves are frozen soil and glutinous rice milk, even if they are hammers and rods, they may not be able to chisel through them, and of course they will protect the huge burial chamber.

When it melts in the spring of the following year, it has the stickiness of glutinous rice milk, and the frozen soil is like a ball of rice cakes, and although it becomes soft, it does not collapse directly downwards like ordinary frozen soil.

In the process of thawing the permafrost, because wood is tougher and malleable than stone, it can maintain the integrity of the tomb to a large extent, which is equivalent to an extra layer of stakes to fix the frozen soil outside the tomb, which directly and completely supports the tomb, so as not to collapse the tomb due to the thawing of the frozen soil.

After this kind of frozen soil melts, it is easy to change the form, these Mongolian people in order to find the mausoleum, will kill the little camel in front of the old camel, and when worshipping, you can lead the old camel to find the tomb, let the old camel sniff the blood to find the location where the baby camel died, so that you can also find the accurate burial place.

When Sun Daqiao said this, he nodded at them: "I wonder if Yuan Tiangang and Li Chunfeng used this method to keep the entire tomb dynamically stable in the frozen soil, and with this huge wooden tomb, maybe it can really maintain stability in the frozen soil." ”

"That being said, didn't they expect wood to rot too? After thousands of years, these woods are likely to rot in 10,000 years. Yue Guanchao questioned.

Sun Daqiao nodded: "I just said that, I don't know if this kind of hanging pile burial is true or false." ”

He paused, and then said: "Although this kind of hanging pile burial may be fake, I remember that there is a form of tomb that was indeed adopted by the nobles of the Yuan Dynasty, and that is the secret burial system of the suspected tomb. ”
