After a long time of probing, they 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 first part of the passage is reinforced with green bricks, but further down is the loess, which looks like a robbery hole.

"You see, the places below that don't have green bricks are full of shovel marks, which were dug by our peers. Zhang Haike said, he leaned in and sniffed, "Qi is dead air, we should be the starting point here." ”

"Didn't you dig in from the outside?"

"It shouldn't be, but I can't see the end, I don't know where to lead, it's hard to say. "With all due respect, this really doesn't look like a tomb, and if it's a robbery hole, how can there be a mechanism on the mouth that can be closed?" ”

"Not a burial chamber?"

"It's not even a grave. "That's human.

"And what do you think this place is?"

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

"It's a Pro Card. The man continued, Linka is a temporary underground rest stop set up when tomb robbers discover a particularly inaccessible ancient tomb, where they will stock up on food and equipment and work underground for a long time.

Most of the Linka are very simple, like an adobe house, but if it is some super difficult to enter tombs, or super large fortress-like tombs, Linka will be very carefully built, because a Linka may take five or six or even ten years in this kind of tomb excavation.

If this is a temporary card, it can explain something, but what about the things above their heads?

"Lend it on your shoulder. Zhang Haike shouted, flew up and stepped on his companion's shoulder, and lit a fire to look at the things hanging on the roof.

This time he went to see the combination of the ceiling and the coffin, and then looked at the other thing hanging upside down on the side, his face changed, and he turned over and said, "Everyone, this is really a temporary card." ”

"How could Linka be like this?" said the others.

Zhang Haike said: "They have no choice, they have to make this place like this." He patted the ground, "I'm afraid there's a big guy under this room, and it's hard to deal with." ”

"It's all about the vibrations. Zhang Haike said, "This method of hanging things up is very similar to hanging hammocks on a sea ship, where sailors sleep in hammocks, and no matter how the ship is bumpy, they will not turn over, so they can rest well." ”

"Is it worth it to hang things so high for the sake of vibration? ”

"If the shock is loud enough. Zhang Haike said, "Big enough, and frequent enough, perhaps, more than a dozen times a day, then, you need a safe way to protect the artifact you just stolen." ”

"What about this mechanism? How do you explain this mechanism? You would have a mechanism in your rest stop?"

"I can't say for sure, because we can't go back in time and ask the people who built this place what happened, but I don't think it's a mechanism, it's a siren. ”

"Go on. ”

"This mechanism is very sensitive, and it extends to the ground, if there is a violent vibration here, then people will be in danger, they can't just protect the artifact and not protect themselves, so they made a vibration detector here, as long as there is a vibration to trigger this mechanism, this opening will be opened immediately, maybe it is safer under this thief hole." ”

"It's safer to steal the hole?" said one person, "It's a bit far-fetched." I think it's also possible that this senior who entered below was alone, and the entrance of this thief hole might not be very safe if it was not closed, and something would climb up, so he made this mechanism, and after he went in, he closed the secret door, and when he came back, he kicked the door panel, and the door opened as soon as the top shook. ”

"You won't kick the zongzi?" said the other human, looking at Zhang Haike, "How did you come to those conclusions just now?"

"The hooks that hook things on the top are all live hooks, and when I look at the bottom, there are springs that hit the steel bars, which are the parts of the shock absorber, and these parts usually make these things look like they grow in the ceiling, but when they encounter vibration, they can greatly absorb the shock. There are also bricks and bluestone slabs here, why they are turned upside down as if they are turned over, it is because all the materials are probably dug out of the ground. The bluestone slabs were too heavy, so they spread them to the bottom, and the bluebricks were used to build the place. So, I said that there must be a large ancient tomb under this Linka, and the scale must be very large, so they will use local materials and build such a rest stop here. ”

"Makes sense. These people all nodded, Zhang Haike was no longer complacent, and continued: "This door is heavily guarded, and it may also be the reason for the existence of this Linka. This thief hole located on the floor and going down is protected by a mechanism at the entrance, so it is safe to think of it, so we must go in and explore it. ”

There is no need to talk nonsense, all of a sudden, the confidence returned to this group of Zhang family children, and several people looked at each other and left. Zhang Haike was the first, and the others followed, and Yuguan jumped into the thief hole.

The thief hole went almost straight down, and they used their feet as brakes to slide all the way down, quickly sliding to the bottom of the thief hole.

This process slid for a full four or five minutes, and when I looked up, it was pitch black, and the opening that came down was completely invisible.

At the bottom of the cave was a circular cavity, and a brick wall appeared in the cross-cut loess on the other side, which had been broken, and strangely enough, the hole was only the size of a fist.

"This hole, voyeurism is not enough. "One humane.

Zhang Haike kicked the ground and found that there were a lot of green bricks under the loess, so he said: "No, it seems that the people last time wanted to re-plug this hole, but the remaining hole was not completed in the end, and the raw materials were still scattered here." ”

The hole was too small, and the light of the fire fold could not penetrate inside, Zhang Haike flicked a fire fold into it, and with a "pounce", it seemed that he immediately hit something, and then fell down, and it was extinguished in an instant.

"Reach out and go in. Zhang Haike said, he looked around at a few people behind him, "Whose turn is it?"

"Zhang Qiling. But I'll do it. One of them said, saying that he took off his coat and exposed his arms, Zhang Haike took out a horse leg scissors from his backpack, stuck the hole, pressed the strength of his whole body, and asked, "How many inches do you keep?"

"A palm at most. The man, as he spoke, put his hand into the hole and began to grope for it.

Everyone held their breath and didn't dare to speak, this was a very dangerous move, once there was any change in the hole, Zhang Haike would press down the horse's leg scissors, cut off the man's hand, and abandon the pawn to protect the car.

But the man touched it a few times, and nothing terrible happened, so he withdrew his hand, and everyone saw that his arm was covered with greenish-black dirt, and it seemed to be very damp inside.

"What did you touch, what is it against such a wall?"

"It's personal. "On the other side of this wall, leaning against a man, is a leather corpse, and it is full of this kind of mud." ”

"Are you sure?"

"I touched something and came out. The man rubbed the sludge onto his clothes, and when he spread his hands out there was a cloud of dirt, which they rinsed with water and found a pocket watch.

The pocket watch is completely broken. Zhang Haike turned it over and saw a unicorn carved on the steel cover behind the pocket watch. He opened the lid and saw that the needle inside had long since disappeared, and on the inside of the lid there was a photograph of a strange man. He looked, but frowned.

"What is the movement of the corpse?" asked someone on the side. "Leaning against the wall, face in. ”

"That's good, it means that he wasn't sealed alive inside. The man was relieved.

"What a fart, he was not only sealed alive inside, but when he was sealed, he was not the only one in it. Something was chasing him behind him, so he had his back against the wall. Zhang Haike put the watch into his arms and said, "No matter, open this wall, it's a mule or a horse, let's take it out." ”
