I didn't think much about it, so I just shook my head and said no, and Fat continued: "Look, you stupid people won't believe it, so do you think that person might take such a big risk for something with a head and no tail?" ”

"Hey ......"

I was about to have a seizure, but was hurriedly stopped by the fat man: "Tell the truth, talk about the business...... the fat man paused: "If I just give you a message, of course no one will believe it, so he must have got something that can confirm it." ”

"What's that?" I asked.

"Then how do I know, you have to catch that person."

The passage is artificially built, not cement, and it seems to be completely artificially excavated in the mountain, which is difficult to complete in an era when there were basically no live tools. In fact, to make a comparison, in ancient times, there is no difference between the construction method of the Republic of China, the Han tomb of the Western Han Dynasty actually does not look very big, open the mountain for the tomb, a straight road splits the mountain, and continues to chisel out the tomb on the wall, this kind of tomb with an area of only one or two hundred square meters, but it takes more than ten years or decades to chisel out. The same is true in the Republic of China, digging a road in the mountain can only be done by hand with chisels, because this kind of relatively delicate project cannot use explosives.

The road is very long, and it is difficult for us to think that this is the work of the black lama. This kind of huge amount of work is not the work of hundreds or thousands of people, not to mention that these people are not all workers.

In response to my question, the fat man's statement was that this was actually a mining process in a mine, using a small amount of explosives to blast at a fixed point. The passage can be opened layer by layer, and the length of the tunnel is based on the number of explosives and the design structure. According to common sense, as long as there is enough explosives, the structural design will not collapse easily, and this corridor can be extended all the time.

But this theory was immediately refuted by the old generation, we did not find traces of high-temperature glazed glass caused by explosives blasting on the wall of the corridor, even if it was a small amount of blasting at a fixed point, this kind of wall is not as polished as it is now.

The two of them argued endlessly, each with their own reasons, anyway, I am on the side of the old generation, I don't think that the black lama will spend so much effort to build such a long road just to hide the treasure, the reason is not only the value does not match, but also the relationship of the news blockade, to build this road, even if it is as the fat man said, it will be no less than 100 people, then even if the black lama is so mad that all of them are slaughtered, then this kind of news will definitely spread some.

As I walked forward, I counted my steps at the same time, and when we reached about 180 steps, our flashlight shone at the end of the road.

"No way?" The fat man scratched his head and said in surprise.

I also thought it was very strange, but I still walked up, even if there was no way, I firmly believed that seeing is believing, and finally it turned out to be just my own perspective. At the end of the tunnel is an arc-shaped depression inward, and there is a shaft down the hollow, and when we get closer, we find that there is no rope, but on the wall at the end of the corridor, there are two stone buckles in the shape of cow nostrils. The original purpose of this place was supposed to be for a rope ladder, but I saw that there were still debris in the gaps, and the fat man pulled them out, which should have been rotten rope sleeves.

"Did the kid fly down?" The fat man glanced down the shaft.

He didn't care about the rubber bands on the Caucasian people before, so he asked this, and it just so happened that I had the two rubber bands used to tie me and the fat man, and then took them out: "Maybe it's this thing, he still has more than a dozen pieces on his body, I don't know what this thing is, one meter at a time, and it can be pulled to a length of four or five meters." "I looked down along the light, but found that I couldn't see the bottom, and I noticed for a long time that the bottom was not high, only fourteen or fifteen meters, and it was only because the color of the ground at the bottom echoed the light of the flashlight, so I saw it as foggy.

The fat man took the rubber band in my hand, this rubber band is specially treated, the surface is burnt brown, and the metal fasteners are very neatly installed at both ends, one end is male, and the other end is female, so that not only a single one can be wound into a ring, but several separate ones can also be connected to each other as an extension length.

The fat man took the rubber band and weighed it in his hand a few times, he pinched two of the ends, and tried to pull them apart, and sure enough, the rubber band was pulled away several times in a row. The fat man looked at me and said, "This is the horned cow's tendon, specially treated, if you keep using it, it will become stronger and stronger, if you put it for a long time, if you store it in the wrong way, then it will soon become a dry branch." ”

"You know?" When I saw that he was talking about the Word, I asked.

The fat man shook his head: "I have heard that the tomb robbers use, their group of people is called the upside-down hanging pockmarks by other factions, and they generally use this elastic cowhide band to tie their bodies, make an opening on the top of the tomb, and hang them directly upside down, without touching any part of the tomb, they can take away the dead weapons in the tomb, take things, and with the strength of their waists, they can bounce back by themselves." But it seems that you have to control your weight, otherwise the rubber band will not rebound, and the rubber band will collapse directly. ”

"Where did you hear that?"

"Do a line, love a line, these things can be used or need to be studied and studied." The fat man replied.

We looked at the shaft structure, and it was very simple, it was a straight road, which was much straighter than the one we were walking on. Looking back at the Yongdao, you can't see his longitudinal deviation with the naked eye, and it can basically be determined that it is straight. But at the level, the bunker is higher, so the drop is estimated to be at least two meters.

When I turned my head, I noticed that the old man was squatting in the corner and didn't know what to do, and then I remembered that after we arrived here, he had not said anything.

I approached the fat man and saw him clasping something through a few narrow crevices in the corners of the ground. Seeing that he was digging something, I asked, "Is there anything?" As I spoke, I squatted down and saw that he was using his fingernails to pull out the contents of the cracks.

Immediately I realized that the things were still gray-white sand powder: "This ......" I wondered, not understanding what he meant.

The old generation was surprised to see me and the fat man, so he picked up a small lump of sand powder in his palm and explained: "There is also that strange sand powder here, I estimate that the entire corridor is filled with this kind of powder." ”

"It's useless to fill it with this kind of thing, and you should use stones to block the door." I said.

After listening to my words, Lao Dai shook his head: "It's not what you think, the use of this sand may not be what we imagined, I want to ......" As he spoke, Lao Dai slapped the sand powder he was holding on the wall, and then saw him rub it hard.

At this time, the fat man and I were even more confused, we looked at each other, and the fat man shook his hand in front of the old generation: "Are you okay?" Isn't there anything wrong with it? ”

The fat man's words drew back the rolls of the old generation's glances, but he still didn't stop, and continued to rub the wall until all the powder in his palm and in front of the wall was scattered, and he didn't stop.

The old generation patted off the dust on his hands and wiped the dust off the walls. There were many tiny scratches on the walls, and he wiped them a few more times before he wiped them clean.

"Give it a try." Lao Dai said.

We didn't know why, but we still reached for the wall, which was still smooth, but the wall that had been rubbed was very rough, full of sunken scratches. I scratched it with my fingernails and found that the walls were very hard, and they looked like whole granite. Until this time, I still believed that this was not a project that could be excavated by the Black Lama's people, at least tens of thousands of people could spend decades or hundreds of years to excavate.

I turned my head to look at the fat man: "I think you are still wrong, this kind of granite can't be blasted for construction, at least they don't dare to blast for construction, and such a long road, I don't know how long it is below, I estimate that it is impossible to dig it out in twenty or thirty years." ”

The fat man was a little unconvinced, and wanted to move out some construction methods to refute me, but was immediately stopped by the old generation: "Don't argue, our guesses are all wrong, and the way this road is excavated is very likely to be another way." ”

I asked with the fat man, and the old man raised his palm that was holding the sand powder just now and said, "That's the sand." ”

"Sand? Do you chisel a wall with this sand? The fat man felt even more ridiculous when he heard it, he was already very resistant to the original manual excavation with his bare hands, but now the old generation said this magical result, which made him even more convinced of his blasting theory.

"It's grinding, similar to the diamond powder used in cutting high-strength steel. The powder of this sand is similar to that of a cutting aid, and it can easily leave marks on the granite. As he spoke, he pointed to the rough wall that had been rubbed out.

When the fat man thought about it himself, he seemed to have figured it out immediately, after all, he was not a person who was too stubborn, and he knew that this method was indeed possible, and a large number of similar abrasive powders appeared here, so now it is basically to find fault with more doubts.

Historical civilization for tens of thousands of years, a variety of large-scale projects are heavy, a large number of consumables are stones, and those huge stones are a very huge problem when mining, hundreds of quarrying processes, similar to the old generation proposed, in ancient times also often had luck, and there is a written record, is the cutting of the huge stone of the Egyptian pyramids.

They used the canal to transport the quarried huge stone to the construction site, and then used a flat-edged saw to draw a mark on it, the flat-edged saw does not play a cutting role, the real force is actually sand, they put the fine sand under the saw, pull the saw will drive the sand to rub against the granite, the depth of the notch will gradually widen, as long as the fine sand continues to be poured in, you can quickly divide the huge stone, and the pyramid construction of a large number of strip stone cutting, basically used this way.
