Seeing the plank and the steel pegs on it, both of them knew what it meant. This proves that the two of them were completely correct in their previous guesses, and this place has indeed been excavated before, and the planks and steel nails are the strongest proof of this.

Umbrella Shishuai thought for a while, and pulled the flashlight in Chen Ziyang's mouth, this time the force was very great, obviously Umbrella Shishuai was very excited, and almost tore off Chen Ziyang's front teeth, and Umbrella Shishuai took the flashlight and plunged into the thief hole.

He specializes in the art industry, and he is still the best at digging the soil, so Chen Ziyang did not rush to ask him what he was doing in there, but stayed outside the robbery cave and carefully studied the wooden planks and the steel nails on the wooden boards, hoping to find some clues from them.

The texture of the wooden board is very hard, Chen Ziyang is not very familiar with the wood, so he doesn't know what kind of wood it is, the edges of the wooden board are already a little rotten, making the originally sharp edges and corners rounded. The steel nails are relatively well preserved, except for a little rust stains where the steel nails come into contact with the wooden board, the rest of the places are very bright, and it is no wonder that they will reflect the beam of the flashlight.

The surface of the steel nail is yellow, and it seems that this is a high-quality steel nail, and the surface should have a layer of anti-rust plating. But even so, the steel nails are still rusty, and it seems that the time buried under the soil layer is not short, at least two or three years. Wood planks are susceptible to moisture, and when the planks absorb the moisture from the surrounding soil, they will conduct this moisture to the top of the nails, so the nails will rust where they come into contact with the boards.

There are many grooves on the nail body of the steel nail, and these grooves are one after another, extending from the tip of the steel nail to the round head of the steel nail, and it can be seen that whether it is this wooden board or this steel nail, it will never appear here by accident, which is obviously carefully prepared, using these wooden planks and steel nails to bear the load and prevent the cave from collapsing.

Just when Chen Ziyang had just finished studying this plank, with a large amount of sand, Umbrella Shishuai came out of the thief hole, and at the same time he was holding two other planks in his hand.

Umbrella Shishuai stood at the entrance of the cave, looking left and right, looking at the surrounding mountains and rivers, and from time to time leaning down to grab the broken soil and gravel he dug out of the thief hole and looked carefully. After studying for a long time, Umbrella Shishuai threw down the things in his hand, patted the sand on his hand and said to Chen Ziyang:

"There have been excavations here before, you see the environment around here, the slope of the hill is very gentle, and the soil here is very soft, digging holes in such places is most likely to collapse, so it is very necessary to use these planks to build a simple load-bearing device, which I ignored before."

Chen Ziyang understood what Umbrella Shishuai meant, in fact, it was not that he was careless, but that the previous few people were not fully prepared at all, even the place where the thief hole was dug was demarcated by himself not long ago, so Umbrella Shishuai made a hasty move without investigating the surrounding environment, and it was understandable that this kind of mistake occurred.

Although several people went down to three tombs in the past two years, they actually only had one experience of digging a robbery hole, that is, the robbery hole they dug outside the shallow water in the Yuhualong tomb when they robbed the tomb for the first time. However, at the time of the excavation, it was in the mountainous area of Tohoku, where almost all the mountains were rocky, and it was difficult to dig a hole there, so there was no need to worry about collapse.

Looking at the wooden board in his hand, Chen Ziyang was thinking about who was digging here before, but no matter what the identity of these people was, there was definitely a master among them. This is not Chen Ziyang's boasting, just in terms of the ability to find dragon points, there will definitely not be more than 20 people in the world who can surpass him.

I have been passed down by the old way of eating in vain, plus I have eaten it thoroughly, and I have looked at the methods of countless tomb robbers for more than 1,000 years, combined with the longevity of their respective families, and their own unique method of yin and yang eyes to see qi to have today. Even so, it took a lot of effort to point out the acupoints before, and I redrew five or six sketches alone.

The vegetation in this vicinity has not been destroyed on a large scale, and it is not said that a pit on the left and a ditch on the right have been excavated in a net-like manner. Therefore, the people who dug here before must have found the hole at once, just like themselves, so there is definitely a master of finding the dragon point in this group. I just don't know if this gang succeeded, and it is unknown whether this robbery hole was buried by them before, or whether it collapsed naturally later.

Having learned a lesson, in order to avoid the collapse of the robbery hole, the umbrella stone shuai asked to find some supports, and also like the previous people who dug this hole, digging and reinforcing it, so that the robbery hole can be dug for a long time. But where can you find a support similar to a plank in this barren mountain?

After all, the grassland area is short of materials, so the herders living on the grassland often replace what they need with some unique methods and nearby things. Ness suggested that they use the coffins they had dug up as supports.

As soon as this idea came out, Chen Ziyang and Umbrella Shishuai hurriedly gave him a thumbs up. Yes! Those urn coffins have been buried here for so many years, and they are still very strong, even if the umbrella stone marshal has to spend a lot of effort when he smashes the urn coffin. Moreover, the fragments of these urn coffins are curved in shape, which is also best suited for support.

This principle is like that of an arch bridge, where the curved thing is particularly effective in bearing the pressure from the arc surface. So a few people drove back to the place where the urn coffin was dug before, picked up some large pieces of urn coffin fragments, filled a full car, and rushed back to the thief hole.

may be because of the guilt of his previous careless mistakes, this time Umbrella Shishuai dug the hole to steal extra hard, and extra carefully. Every distance he dug up, he supported himself with the fragments of the urn coffin to the left and right of the cave and above it. Although the speed of excavation is slightly slower, the excavated hole is unusually strong, and with the support of these urn coffin fragments, several people's hearts are also a lot more steady.

Because the two of them really don't understand this kind of work, and they can't help much, Chen Ziyang and Nice can only help the umbrella Shishuai transport the excavated sand and other wood fragments that have been dug out inside and outside the thief hole.

According to Chen Ziyang's previous calculations, it was necessary to dig down a distance of about 30 meters to reach the hole, so several people were ready to fight for two or three days, but in the evening of this day, when the sun had not yet set, the umbrella stone handsome Hu Ran came out of the thief hole and told them that the thief hole had been dug through.
