The entrance to the tomb is at a depth of less than ten meters, so the tunnel dug by Zhang Housheng is in the shape of a slope. The three of them came to the door of the tomb with their waists bent, and the space here was much larger, and the three of them stood here side by side, which was more than enough.

To the right of the entrance to the tomb, there is also a tunnel that leads to the farmland behind Zhang Housheng's house outside, and the entrance to the cave has been carefully concealed by him, so that it will not be discovered. In addition to being used for ventilation, this tunnel can also be used to escape from here if there is an emergency.

When he arrived at the entrance of the tomb, the third said to Zhang Housheng with a smile: "Big brother, this time I will go down first, if I have an accident, I hope you can help me take care of my mother and children!" ”

Zhang Housheng patted him on the shoulder and solemnly promised: "Third child, don't worry, I have something to eat, and I will definitely not let them go hungry!" ”

The third child nodded, and then with the help of Zhang Housheng and them, he tied one end of the rope around his waist, and then he put on a gas mask, and by the light of the miner's lamp, he climbed into the tomb step by step along the soft ladder, and after a while, his figure disappeared.

At this time, Zhang Housheng and the fourth child were quite nervous, and with the previous two accidents, they were afraid that the third child would have another accident. If there is really an accident, even Zhang Housheng, who is bent on hollowing out this tomb, will definitely retreat in his heart.

After more than ten minutes, the rope didn't move again, which made the two of them nervous, and quickly pulled the rope, to their celebrity, the third child inside immediately gave them a response, so it seems that there should be no accidents.

After about a quarter of an hour, the third child crawled out of the tunnel. Zhang Housheng hurriedly asked, "How is the situation inside?" ”

The third child said with some excitement: "It is estimated that after eight or nine minutes of climbing, you can get to the outer room." The outer room is very spacious, and the main door can be seen from the entrance of the passage. ”

I heard the third child say this. made the other two happy, but after Zhang Housheng was happy, he immediately reacted and asked, "What about the organ?" What happened to Lao Jiu before? Did you encounter a rope hanging stone? ”

The third child was a little gloomy when he heard this: "It is indeed an iron cable hanging stone, Lao Jiu is also unlucky, the other iron cable hanging stones are useless, and the stones have also fallen to the ground, he should have thought that the mechanism has failed, and the result is ......"

Zhang Housheng and the fourth child heard that this was the case. sighed and shook his head gently, this tomb robbery is a job to lose his head, not only if he is caught, he may lose his head, if he is not careful, he will be caught in the path of the mechanism in the tomb, and he will also lose his head.

After sighing, Zhang Housheng immediately asked, "The third child, what about the other organs?" Have you noticed? ”

The third child hesitated for a while and said, "I saw that from the entrance of the tomb to the gate. There are all stones hanging from iron cables, and there are probably no mechanisms on the ground, right? ”

Hearing this, Zhang Housheng asked, "You didn't go in to have a look?" ”

The third child replied: "The ground is full of stones, and it will take me a little time to go in." I'm afraid you'll be in a hurry, so I'll come out first. ”

Zhang Housheng nodded, pondered for a while, and said, "Fourth." The third child and I will go in and have a look now, and you are here to pick us up. What do you think? ”

The fourth child hurriedly said that there was no problem, and then Zhang Housheng went down the tomb with the third child.

Zhang Housheng followed behind the third child. Slowly crawl towards the end of the tomb. He looked around as he climbed, the material used to build the tomb was stone, and there was nothing unusual about it, and there was a dark red mark on the ground, needless to say, this was the blood stain left by Lao Jiu before.

As the third child had estimated before, after eight or nine minutes, the two climbed to the end of the tomb.

When he came to the outer room, Zhang Housheng suddenly felt that his eyes suddenly opened up, stood up, and after a little movement, he began to carefully observe the surroundings.

The walls here are also made of stone, and from their position to the ground in front of the gate, it is indeed all stone, as the fourth child said, so that there is no need to worry about it, and you will encounter the mechanism on the ground again. And on a stone at the door, there were all dark blood stains, needless to say, this was left by Lao Jiu.

The third child signaled to Zhang Housheng, and began to set off towards the gate, he turned over the boulders with fear, and there were no accidents along the way, allowing him to arrive at the gate of the ancient tomb safely.

The material of the gate in front of the third child is also stone, and it is also a folio structure, maybe it was very tight at the beginning, but after more than 2,000 years of vicissitudes of life, the gate at this time has a gap of three or four millimeters.

The third child pushed the door in front of him, but he didn't move, and then he pushed with all his strength, still like this. This made him a little strange, so he double-checked the door, and then a surprised expression appeared on his face.

"What's wrong?"

Zhang Housheng saw that the third child arrived at the door of the tomb safely, and confirmed that it was safe, so he rushed over while the third child was checking the gate.

The third child replied with a wry smile: "This door is actually a tap stone!" ”

Tap stone is an anti-theft measure in ancient tombs, and there are generally two situations.

The most common tap stone is used in stone strips, the principle is this, the craftsmen first make the upper and lower ends of the stone door shaft into a spherical shape, and then in the middle of the two stone doors in the same part of the door seam, carved out a surface protruding groove, and then in the door axis not far from the stone paving ground, chiseled out a shallow front and deep groove.

Before closing the stone door, people first put the stone strip with considerable width in the groove in the ground, and slowly lean forward to make it contact with the stone door.

When people withdraw from the underground palace, the stone bar, with the help of its own inclined pressure and the "ball" action of the shaft end of the door shaft, automatically pushes the stone door to close, until its top falls into the convex groove of the stone door on both shoulders. At this time, whoever wants to push the stone door open from the outside can only be wishful thinking.

The second type of tap stone is the stone ball, which was originally also behind the door, digging a pit and putting the stone ball inside. The difference is that there is a horizontal groove from the position of the stone ball behind the door to the final position, there is one on each side of the horizontal groove, there is a pit at the beginning and the end point, and there is a certain inclination angle, and the pit at the end point is lower.

Since the door was starting to block, the stone ball would not move. As the door closes gradually, the stone ball will roll down the groove and eventually land in the pit behind the door, blocking the door. For example, if you open a door, there is usually a stone ball and a horizontal groove on each side, and when it is finally closed, there is a stone ball behind each of the two doors.

Speaking of which, everyone must understand that it is more difficult to open the second type of tap stone than the first one.

If it is a stone bar, the method of cracking it is quite simple, first, you need to take a relatively strong steel bar, then bend one end with a large hook, and then insert the steel bar along the crack of the door.

After inserting the steel bar, turn it horizontally so that the hook can resist the big stone bar, and then push hard to make the stone bar stand up, so that the tap stone will not resist the door, and the door will naturally open.

As for the stone ball, if it is a single stone ball, it is okay, just use one end of the thin steel wire to make a trap slightly larger than the stone ball, extend the trap from the gap in the middle of the stone door into the door and cover the stone ball, hold the other end of the thin steel wire in your hand, xiangshang lift, raise the stone ball and leave the stone trough, and push the stone door open at the same time, you can do it.

But there are stone balls on both sides, so it's troublesome, because you can't see the location of the stone balls through the crack in the door, and it's not so easy to get the stone balls.

Zhang Housheng was stunned at first when he heard this, although the principle of the tap stone is also simple, but he really didn't expect that this kind of ancient tomb in the pre-Qin period would also have this kind of device, and when he came back to his senses, he hurriedly asked: "What kind of tap stone, is it a stone ball or a stone bar?" ”

"Judging from the crack in the door, it should be a stone bar."

When Zhang Housheng heard that it was a stone bar, he immediately breathed a sigh of relief, and when he opened the first kind of tap stone, he needed to get a steel bar that met the requirements.

"Let's go, let's go back first!"

The third child hesitated for a moment when he heard this, and said, "Big brother, why don't we blow it up!" My heart was beating so hard that it was like something was going to happen. ”

Zhang Housheng frowned and said, "Third child, it's not me saying you, if something is going to happen, then we have to be calmer." If, as you said, we blew the door open with explosives, not to mention that we might shatter or smack the treasure inside, wouldn't it be even worse if the sound came out and alarmed the others? ”

Speaking of this, he patted the third child on the shoulder and said: "The third child, I also know that you are thinking about our safety, but there is a way that you can't eat hot tofu in a hurry, tomorrow I will go to the Wu blacksmith in the town to get a tool, tomorrow night is the time for us to harvest, we are not in a hurry at this time, don't you say?" ”

The third child felt that Zhang Housheng's words were also reasonable, so he said: "Well, big brother, I listen to you." ”

Zhang Housheng smiled at him when he heard this, and then the two returned to the ground along the same path.
