"So how deep do we have to dig to discern the difference in the subsoil?"

I don't know when, Hu Qi had already finished observing the surrounding situation and walked to our side, looking at Lin Zi with some high interest, and asked Lin Zi. Pen, fun, pavilion www. biquge。 info

Lin Zi's explanation is very general, he just said that it will vary from grave to grave; Because we don't know the size and depth of the tomb, the map is not deliberately marked. Moreover, according to Lin Zi, because the "flower soil" is easy to expose the target, the ancients also came up with a method, that is, when digging a burial pit, the excavated soil is stacked from the bottom to the top in different orders, and then backfilled when the soil is sealed.

The mausoleum of the emperor of the Yuan Dynasty has not been found so far, and such a secret burial is directly related. At the time of the secret burial, the Mongols dug the pit very deep, but the soil could not be dug up, it had to be clumped. The clods of soil should be carefully placed in order, and after the coffin is buried, the clods should be put back in their original position.

At this time, I knew that the principle of the Jieling faction using iron drills to explore ancient tombs turned out to be such a method, and I couldn't help but feel sincere admiration for the high-level IQ of the tomb robbers' predecessors! Recall that we Han people didn't think so far ahead, and it seemed to be informal. Not only is it not a secret burial, but also for fear that the world will not know, the old and high graves are piled up for people to watch. This kind of carelessness, whether intentional or unintentional, has provided excellent targets and opportunities for tomb robbers for thousands of years.

Lin Zi's statement basically determines the scope of the pit we want to dig, because the top of the mountain is at the highest point of the tomb, and we don't know how big the tomb inside is, and it is difficult to say that we can't see the top of the tomb if we dig a hole of more than ten meters; At the foot of the mountain, it is more inconsistent with the characteristics of the tomb, so we chose the relatively more likely halfway up the mountain, and according to the drop, we can find the position of the top of the tomb very accurately and time-saving.

Mausoleums generally built in the belly of the mountain, in order to prevent the collapse of the mountain and water seepage, the tomb roof will inevitably be built; The soil used in the top of the tomb is generally white plaster mud with high viscosity and trihexin, which is composed of lime, clay and fine sand, and its actual ratio depends on the sand content of the soil. It has a certain strength and water resistance after layering and tamping, and it is said that the ancient Sanhe soil is harder than cement.

However, there are more prohibitive anti-tomb robbery methods on the Sanhe soil, the most famous is the eight major moves in the tomb of Qin Shi Huang;

The first trick "crossbow shooting": "Let the craftsman make a crossbow arrow, and shoot those who are close."

The second trick is "live and pit killing": "Those who close up the craftsmen and those who come back will not come".

The third trick "tomb poison poisoning": "use mercury as a hundred rivers and seas, and instill the machine".

The fourth trick: "bury in the sand".

According to the records of the Records of the First Emperor of the Qin Dynasty (Volume 6), there is also a "hole digging trick": it means digging deep into the tomb so that ordinary tomb robbers cannot dig it at all, and it is called "piercing three springs" in the book. "Iron bucket move": In short, the underground palace is made as strong as an underground air-raid shelter, even if the tomb is dug, it is not easy to open, this saying is also called "under the copper and to the coffin". "Camouflage move": After the completion of the tall sealing of the earth, the soldiers and laborers who built the Mausoleum of the First Emperor carried out strict camouflage on the mausoleum, so that the living people will only think that it is just a mountain bag after looking at it, and will not suspect that it is a tomb, which is the so-called "trees, grass and trees like a mountain".

Lin Zi told us a lot about the construction of ancient mausoleums and about anti-tomb robbery, and it can be seen that he has learned a lot of useful knowledge under the pressure of the old man, at least for now, it is very useful to us.

At this time, it is already sunset, in order to avoid unnecessary trouble; We've changed all of our work to night operations, so all we need now is to recuperate! There is nothing on the bare mountain buns, and the rabbit meat eaten at noon still feels a little unfinished; It's just a pity that the good days often pass quickly, and we are now about to start munching on this dry, tasteless compressed biscuit, which is really sad to look back on......

We relied on the huge rocks to set up tents as temporary camping sites, and did a good job of division of labor early; At night, Hu Laoqi sat in the base camp to guard the base area for us, while Lin Zi and Hu Qi and I were hard-working laborers, going to the halfway point of the mountain that had already been marked to dig one by one to find the location of the tomb.

Although we walked all the way, we didn't feel how tired we were at this time; I suddenly discovered why so many people like to go on adventures with nothing to do, and many people around the world know the famous answer, in 1924, when a New York Times reporter asked Mallory why he wanted to climb Mount Everest, he said, "Because it's there." ”

The night came quickly, and gusts of cold wind hit, even though I was wearing a world-famous American special forces combat uniform, I felt a little chilly on my body; I was nervous and excited, and I was a little at a loss under the five tastes.

The once well-known Luoyang shovel has been replaced by our folding sapper shovel. Again, it's ironic that this is the equipment of the world's top troops, and now it is used by us to rob tombs. When it was completely dark, Lin Zi and Hu Qi set off one after another, carrying all the tools we could use, and walked towards the halfway up the mountain.

I suddenly wondered, is it safe to leave Hu Laoqi alone in the tent? But then I gently put that thought out of my mind; There are two reasons, first, the location we selected is not very far from the camping place on the top of the mountain, if we encounter any unexpected situation, Hu Laoqi will definitely fire a warning shot, so we have enough time to rush to help; Second, Hu Laoqi, as a perennial "person who has come over" who has been out and fighting all year round, must have his own killer skills, and should have the ability to defend himself in the face of sudden crises.

Soon, we reached the nearest marker; Hu Qi was the first to throw away some of the things he was carrying that he couldn't use for the time being, and then took out a sapper shovel made of stainless steel and dug it on the ground; I have to say that Hu Qi's digging speed was very fast, and within a few minutes, a circular pit with a diameter of seventy or eighty and a depth of more than one meter was dug out by him. If I come, it is estimated that I will not be able to dig half a meter, intentionally or unintentionally, I suddenly remembered Xinghuayan, his speed is much faster than Hu Qi, right? Don't know where he is now? When will we meet again?

I shook my head so that my mind no longer flew around, and in the night, the woods around me grabbed the soil dug out by Hu Qi from time to time, and became an inspector, identifying the only way to enter the tomb for us; But judging from his unchanged face, it seems that nothing has been discovered!

The surroundings are very quiet, and we can only hear the sound of Hu Qi digging a thief hole, which looks so distressing in the dark night; Further down, you need the help of the people above, I put the prepared bucket inside, and Hu Qi below loaded all the wet soil with nowhere to put it into the bucket, and then I and Lin Zi transported it outside, the whole process was boring and boring!
