After a long time of testing, the few people felt that there was not much danger, so they entered the tomb again and came to the edge of the passage.

The passage is very deep and strange. The beginning of the passage is reinforced with blue bricks, but further down there is loess, which looks like a thief hole.

"Look, the areas where there are no blue bricks down are shovel marks. This is what we dug together." Zhang Haike said, and he leaned closer to smell it. "Aura is death, and we should be the starting point here."

"Didn't it be dug in from outside?"

"It shouldn't be, but I can't see the end and don't know where it leads. It's hard to say." One person said, "I'm blunt, this is really not like a tomb. If it's a thief, how could there be a mechanism that can be closed in the opening? It's impossible for someone to dig directly into the secret passage of the tomb's mechanism, so I think this is definitely not a tomb."

"Not a tomb?"

"This is not even a grave," said the man.

"Then what do you think is this place?"

"This place was not built by dead people, but by tomb robbers."

"This is a pro card," the man continued.

The direct card is a temporary underground rest station set up when tomb robbers find a particularly difficult to access to the ancient tomb. They will hoard food and equipment in it and operate for a long time underground.

Most of the cards are very simple, like adobe house, but if it is some super difficult to access to ancient tombs or super-large fortress-style tombs, the cards will be built very finely, because a card may take five or six or even more than ten years to excavate such tombs.

If this is a pro card, it can explain something, but what's going on with the things above their heads?

"Lend your shoulders to use it." Zhang Haike shouted, flew up and stepped on his companion's shoulders, and fired a fire and saw what was hanging on the roof.

This time he went to see the junction between the ceiling and the coffin by himself, and then looked at the other thing hanging upside down on the side. His face changed. He turned over and said seriously: "Everyone, this is really a pass card."

"How could the Pro Card look like this?" said the others.

Zhang Haike said: "They have no choice but to make this place look like this." He patted the ground: "There is probably a big guy under this room, which is difficult to deal with."

"All designs are due to vibrations," said Zhang Haike. "This way of hanging things is very similar to a hammock hanging on a sea boat. The sailors sleep in the hammock. No matter how the boat bumps, they will not turn over, so they can rest well."

"Is it worth it to hang things so high for vibration? It's not easy."

"If this vibration is large enough," Zhang Haike said, "It is large enough and frequent enough. Perhaps, it is more than ten times a day, then it is necessary to have a safe way to protect the underworld weapon he just stole."

"What about this agency? How do you explain this agency? Will you set up an agency in your own rest station?"

"I can't be sure, because we can't go back in the past and ask the people who built this place what happened, but I think this mechanism is not a mechanism, but an alarm."

“Continue.”

"This mechanism is very sensitive and reaches the ground. If there is a violent vibration here, then people will be in danger. They cannot only protect the underworld but not themselves. So they have made a vibration detector here. As long as there is a vibration, the mechanism will be triggered, and the hole will be opened immediately. Perhaps it will be safer under this thief."

"It's safer under the hole?" said one person, "It's a bit far-fetched. I think it's possible that the senior who entered the hole was alone, and the hole in the hole might not be safe if it was not closed. Something would climb up along the way. So he did this mechanism, and after he went in, he closed the secret door. When he came back, he kicked the door panel, and when he was shocked, the door opened."

"If you kick the rice dumplings, you won't kick it?" said the other person, and then looked at Zhang Haike, "How did you come to the conclusions just now?"

"The hooks that hook things on them are all living hooks. I looked at the bottom, and there were springs made of steel bars. These parts usually make these things look like they are growing in the ceiling, but when they encounter vibration, they can greatly absorb shock. Also, why are the bricks and bluestone slabs here pressed upside down like the whole thing? It is because all the materials are probably dug out from the ground. The bluestone slabs are too heavy, so they lay them to the bottom, and the bluestone tiles are used to build this place. So I said that there must be a large ancient tomb under the head of the card, which must be very large in scale, so they will use materials on the spot and build such a rest station here."

"It makes sense." These people nodded. Zhang Haike was no longer proud and continued: "This door is guarded by heavy troops, which may be the reason for the existence of this card. This thief hole located on the floor and the hole is protected by the mechanism. It seems safe, so we must go in and explore it."

There is no need to talk nonsense, all of my confidence returns to the Zhang family children all at once. A few people look at each other, let’s go. Zhang Haike is the first, and the others follow him, jumping into the thief hole one after another.

The hole was almost straight down. They used their feet as the brakes to slide down and quickly slid to the bottom of the hole.

This process slid for four or five minutes, and then looked up. It was pitch black and the hole was completely out of sight.

There is a circular cavity at the bottom of the thief hole, and another brick wall appeared in the loess cut across the other side, which has been broken. What is strange is that the broken hole is only the size of a fist.

"This hole is not enough for voyeurism." said one person.

Zhang Haike kicked the ground and found that there were many blue bricks under the loess. He said, "No, it seems that the person who came last time wanted to block the hole again, but in the end, the hole was left but the raw materials were still scattered here."

The hole was too small, and the light of the fire slash could not penetrate inside. Zhang Haike bounced a fire slash and entered. With a "punch", it seemed to hit something, and then fell down and was extinguished in an instant.

"Extend one hand in." Zhang Haike said, looking around at the people behind him, "Who is the turn?"

"That little devil. But I'll do it." One of them said, and he took off his coat and exposed his arms. Zhang Haike took out a horse's leg cutter from his backpack, stuck the hole, pressed on his whole body's strength, and asked, "How many inches left?"

"At most, one palm." The man said, and then stretched his hand into the hole and began to grop.

Everyone held their breath and dared not speak. This was a very dangerous move. Once there was any change in the hole, Zhang Haike would press down on the horse's leg cut, cut the man's hand, and abandon the pawn to protect the car.

But the man touched him a few times and nothing horrible happened, so he shrank his hands back. Everyone saw that his arms were covered with green and black soil, and it seemed very wet inside.

"What did you touch? What was against such a wall?"

"It's a person." The man said, "The other side of this wall is leaning against a man, and there is a corpse of leather, and it is full of this mud."

"Sure?"

"I touched something." The man rubbed the sludge on his clothes, spreading his hands out of dirt. They rinsed it with water and found it was a pocket watch.

The pocket watch was completely broken. Zhang Haike turned it over and saw a unicorn carved on the steel cover behind the pocket watch. He turned on the cover and saw that the needle inside had stopped leaving. There was a photo on the inside of the cover. There was a strange man in the photo. He looked at it, but frowned.

"What is the movement of a corpse?" someone asked next to him.

"Look on the wall, face inward."

"That's good, it means he was not sealed inside." The man said with relief.
