With this important situation, Chen Ziyang came to the spirit, he hurriedly took the sapper shovel he bought, and after walking along the west wall, Chen Ziyang chose a place with more cracks in the wall, ready to start.

There are many cracks in the wall, which proves that the ground here is sinking more severely, and it is very likely that this is the center of the previous passage, and at the same time, Chen Ziyang looked at the mountains in the distance, this place is exactly at the foot of a mountain peak.

The reason why the mountain range is formed is because of the action of the plates squeezing each other, and the extrusion force of the place where the mountain range is formed is relatively large, so the soil and rocks in the plate are squeezed to protrude from the ground, and the mountain range is formed. So in general, it is not possible for the ground to collapse in the place where the mountains are formed, unless the soil below them passes.

Chen Ziyang recalled the news he had seen before, and said that in some areas, there were large areas of cavities due to excessive groundwater pumping or excessive mining of underground veins. Over time, the ground here will collapse for no reason, in fact, because of the effect of these underground cavities.

Thinking of this, Chen Ziyang was even more sure of his thoughts, judging from the area where the ground was sunken, the passage that was dug out here before must be very wide, at least ten meters in diameter. Having roughly found the center of the depression, he started digging down, shovel by shovel.

Chen Ziyang uses the fast excavation method, which is simply digging down quickly in one place, not digging holes, because he wants to confirm whether his idea is correct, which can only be confirmed after digging up the surface soil.

At this time, Chen Ziyang thought of the Luoyang shovel, an artifact for exploring the tomb, although he had never seen or used the Luoyang shovel, but there was a detailed record of the use of the Luoyang shovel, which belonged to part of the recipe.

After all, the Luoyang shovel can quickly show a few meters below the surface, or even more than ten meters of soil in front of people, this time is the time when the Luoyang shovel wields its due effect, but because of the relationship in the northeast, Chen Ziyang has not had the opportunity to get a Luoyang shovel for practice.

The so-called work must be sharpened if you want to do a good job, and the reverse is the same, if a good tool is not used in a place, then this tool will not be of due use.

The mountainous areas of Tohoku are mostly stone mountains, and the soil layer is very thin. Therefore, the large mausoleums in the Northeast are relatively few, after all, the amount of work to open the mountain and build the mausoleum is too huge, and the Northeast region has not had any strong political power, although the Tang Dynasty that opened the mountain as a mausoleum has dealings with the ancient Bohai country in the northeast, but the national strength of the ancient Bohai country is too far worse than the Tang Dynasty, and it is impossible to build a relatively large mountain mausoleum.

Therefore, the large mausoleums in the Northeast are basically built on the natural cracks in the mountain, or the underground space naturally formed in the mountain, or the remaining underground waterways after the water from the underground water system is drained.

Although the previous Bohai Palace borrowed from the Tang Dynasty to open the mountain as a mausoleum, the natural mountain cracks were reinforced with stones, and molten iron was poured into the cracks of the stones, but after all, only a small part of the area did this. If all the Bohai Palaces had been reinforced in this way at that time, the mountain would not have collapsed completely because of the roar of the huge golden bell.

Chen Ziyang was thinking about the matter of the Bohai Palace, and at the same time sped up the degree in his hand. This sapper shovel is really very easy to use, especially the head of the new shovel is sharper, and after a while, Chen Ziyang dug to a depth of more than three meters below the surface. At this time, Chen Ziyang, who was tired and sweating profusely, had a strange thing, and the soil here was a little strange.

Normally, if you dig down from the surface, the deeper you dig, the tighter the soil will be, and the wetter the soil will be. The surface soil is often exposed to sunlight, so the moisture of the surface soil is steamed away, so the surface soil is drier, and it is more labor-saving to dig at the same time, because most of the soil that lacks water is in a sandy state, and the adhesion between the particles is relatively low, making it easier for tools to insert.

But as the depth of the surface deepens, the sunlight cannot reach that deep, so the moisture in the soil is preserved, so the more you dig down, the stronger the adhesion of the soil, and the more water it contains in the soil, because it contains water, the darker the color of the soil.

Even in the jungle, there is a way to get water from the soil, which is to use the fact that the soil contains water. In the jungle, even during the dry season, there is a lot of water under the soil. When people living in the wild are short of water, they can find a shady place, dig up the top layer of soil, and dig down more than a meter to reveal the soil containing water.

At this time, you only need to wrap the water-rich soil with a highly absorbent towel, and wait quietly for a period of time, and the water in the soil will be absorbed by the towel. Then you just need to wring out the towel vigorously, and the water absorbed in the towel will drip out drop by drop.

But the more Chen Ziyang dug up, the more he felt that something was wrong, he had dug to a depth of more than three meters below the surface, but the soil here was still very dry, and there was no moisture at all. It's not a jungle, but the soil shouldn't be devoid of moisture.

After digging for so long, Chen Ziyang really couldn't dig anymore, he grabbed a handful of soil at the bottom of the pit, and then climbed out of the three-meter-deep pit with difficulty with a sapper shovel. Chen Ziyang, who was sitting on the edge of the pit, carefully looked at the handful of soil he had grabbed from the bottom of the pit and compared it with the soil on the surface.

Except that the soil at the bottom of the pit is more compact, the two soils look exactly the same, both the color and the size of the sand grains are very similar, Chen Ziyang feels that something is wrong.

Even if the area is backfilled, the morphology of the soil below three meters and the surface soil should not be so close. When the backfill was just made, the soil of the two must have been exactly the same, but more than ten years have passed, and how much rain will seep into the bottom of the soil in these ten years, and the soil below three meters will definitely have some residual water, and it will not be so dry.

And Lao Lu said before that after the huge diamond fell off from his hand, it went deep into the ground like a drill bit, as if the soil would avoid the diamond by itself, and when the diamond was drilled deep underground, a large amount of clear water gushed out from the bottom of the deep pit.

When Lao Lu and Chen Ziyang discussed this matter, the two of them also briefly studied, it is very likely that this diamond has any characteristics, it will neutralize the composition of the soil, when the diamond falls to a deep place, it should be the hole caused by this diamond connected to a certain underground water vein, so the water gushes out.

The amount of water gushing out was very large, and the current was also very fast, so when Lao Lu and the others escaped, the underground mausoleum was about to be flooded. If you look at it this way, the soil below here should be moister than the soil in other places, so it shouldn't be so dry.

Grabbing this handful of sand, Chen Ziyang looked at it carefully, and he poured it back and forth between his left and right hands. While pouring, Chen Ziyang was thinking about the strangeness of this soil. This place is really strange, why is the soil here so dry?

Chen Ziyang couldn't figure out the truth, so he sighed and said to himself: "There are too many strange things encountered on this trip to Shaanxi, and one after another, I can't figure out the truth." Shaanxi ...... Shaanxi? Shaanxi! My dear, this is a place to raise corpses! ”

There is such a record: the land in Shaanxi is thick and dry, and it is often dug for three or five feet without seeing water. This type of soil is the most susceptible to zombies. Because of this, in some areas of western Shaanxi, funeral customs are peculiar, and people cannot be buried immediately after death, and the body must be exposed to the air. Until the flesh is exhausted, leaving the white bones and then buried, it is to prevent the corpse from becoming a zombie after being buried in the corpse breeding ground.

No wonder the soil here is so strange, more than three meters below the surface, and you can't see the moisture in the soil, this should be a place to raise corpses, after figuring out this layer, Chen Ziyang instantly understood why there is no dragon vein here at all.

Before, he had looked at all the trends of the nearby mountains, but now there was no dragon vein here, and Chen Ziyang comforted himself, thinking that there was some error between the location of the mountain villa and the location of the mausoleum, because of the relationship between the terrain of the mountain villa was artificially selected.

But then the more Chen Ziyang thought about it, the more wrong it became, the distance of one kilometer is not short, but it is not long, especially in the mountains, the distance of one kilometer is almost negligible.

Even if the location of this mountain villa has a relatively large deviation from the location of the dragon's lair, but standing on the top of the nearby mountain range, you should be able to see the trend of the dragon vein, but there is no sign of the dragon vein nearby, Chen Ziyang has been unable to figure it out, and now he understands that the construction of this tomb before was not the dragon vein chosen, but the chosen place to raise corpses. It's no wonder that there are no traces of dragon veins around.

Thinking of this, Chen Ziyang hurriedly got up, grabbed the sapper shovel and ran in the direction of the car he rented. Li Bojian, who was sitting in the car, saw Chen Ziyang running briskly and thought that he had something important, but Chen Ziyang, who was sitting in the car, said a word that extinguished Li Bojian's just budding hope.

"This is a corpse breeding ground, my previous preparations were very inadequate, it seems that you will have to wait a few more days, I need to get some tools to dig up the mausoleum, you wait for me for a few more days."

"What is a corpse ground?"

"To put it simply, the corpse breeding ground is that the soil here is relatively dry, and the people buried here have not decomposed for many years, and it is easy to become zombies, which is just the opposite of the ant farm, the environment of the ant breeding ground is relatively humid, and it is very easy to breed snakes, insects, rats and ants, so the corpses buried there will quickly decay.

Forget it, I can't say a word and a half, anyway, it's getting dark, let's go back today, you give me a few days, I have to prepare, this tomb is not so easy to get into. After Chen Ziyang finished speaking, he moved the car and drove back along the dirt road in the mountains.

"Now I think more and more that you are a liar, and you are still getting zombies out, trying to dispel my thoughts? Let me tell you, I don't believe in these feudal superstitions at all, and your method can't dispel my thoughts, so you should withdraw your thoughts about deceiving me as soon as possible. ”

Li Bojian's words almost spewed out a mouthful of old blood from Chen Ziyang. Good guy, Chen Ziyang thought in his heart, in the past few years alone, he has experienced a lot of strange things, it is a corpse demon and a bloody corpse, and there are letters or something, but now these things have become feudal superstitions in this woman's mouth, forget it, it will never be clear to reason with women, so Chen Ziyang simply kept silent, but concentrated on driving his attention.

Because this dirt road is relatively simple to build, and because it has fallen into disrepair, and there have been no vehicles on the road for more than ten years, the road is overgrown with weeds, and the outline of the road is basically no longer visible. Chen Ziyang had no choice but to slow down the car and judge the position of the road by virtue of the contours vaguely higher than the surroundings.

There is a section of sand on the road, probably because of the soil quality, there are no weeds growing on the road surface in this section of the road, and after the car slowly drove through this section of the sand road, Chen Ziyang suddenly stepped on the brakes. The sudden sudden braking made Li Bojian's body lean forward sharply, and her head slammed on the panel in the cab, and in an instant, a large bag arched from her forehead.

While rubbing the big bag on his forehead, Li Bojian scolded Chen Ziyang, just saying a few words to him, why is it so torturous. But Chen Ziyang turned a deaf ear to Li Bojian's words, and his eyes were rolling in his sockets, as if he was running his brain in an enclave, thinking about something. Immediately afterwards, Chen Ziyang Xun opened the car door, ran to the outside of the car, and ran in the direction of the villa.

Chen Ziyang's sudden strange behavior stunned Li Bojian, and she quickly got out of the car and looked back. Li Bojian saw Chen Ziyang squatting on the section of sand and gravel road he had just passed, staring at the road carefully.

Li Bojian, who felt strange, also leaned over, and after staring at the road for a while, he couldn't see the reason. So she asked Chen Ziyang: "My big feng shui man, what are you staring at, is it because you feel guilty for deceiving me, and you have no face to see people?" ”

"Don't talk, we seem to be being followed!"
