The final choice was to move towards the black group, but Liu Shi's will swayed more and more strongly, and it was not until another shock came that there was a change.

I don't know when, a stronger vibration struck, and the sudden vibration made Liu Shi fall to the ground, and the steady downward force still couldn't support it. didn't have time to think about where the vibration came from and what it represented, Liu Shi's first thought was to rush forward, and that front was naturally the position of the black group. With the arrival of a strong earthquake, Liu Shi felt that the distance from the black group was closer, and he couldn't explain this, but Liu Shi believed in his feelings, and quickly turned over and quickly sprinted towards the black group, inexplicably feeling that time was pressing, maybe at the moment when the earthquake disappeared, the black group would become ethereal again.

Finally, Liu Shi came to the position of the black group, this time he did not pull the distance away, without the slightest hesitation, stepped into the black group, almost at the same moment, the shock disappeared, and a force suddenly struck around, binding Liu Shi, wrapped in strong pressure, the blood almost stopped flowing, the body was red and pale, and the consciousness was a little scattered. For a few seconds, Liu Shi was in an unconscious state, and it only lasted for a few seconds, the power of restraint disappeared, and the person immediately came to his senses. Hurriedly looked around, it was still pitch black, it seemed that the situation had not gotten better, but worse, and there was at least some visibility before.

Suddenly, Liu Shi thought of a problem, and immediately squatted down and groped around in the dark, and felt a flashlight behind him, not knowing what was wrong, and could no longer release the light. Liu Shi relied on his feelings, took out the spare flashlight from his bag, although he fell many times, the things in the backpack were still not much damaged, the spare flashlight was quickly found, and the light suddenly dispelled the darkness nearby.

The mysterious black fog has all disappeared, and the location I am in now is a road, which I can be sure that I have not been here before, because the road is made of stone masonry, and there is not a single blue brick. Behind Liu Shi is a dead end, and the road stretches all the way forward, twisting and turning, and there is no end in sight. Not in a hurry to move forward, Liu Shi thought about how he got in, and his last memory stayed at the moment when he stepped into the black group, but he always felt that he had forgotten something, and the lost memory was very important. After thinking about it for a long time, he didn't recall the lost memory, Liu Shi also looked up and checked the top of the road, and didn't find that there was a secret passage or a hole, even if a person fell down, there must be a hole passage.

No matter how much he thought about it, he couldn't find the answer, so Liu Shi had to walk towards Yongdao. The road under his feet is very flat, and it is also very safe along the way, Liu Shi's speed continues to increase, about ten minutes later, the road suddenly becomes larger, expanding four or five times, Liu Shi found that on the left side of the larger space, there is a layer of silver substance, and the air has also changed, making people feel a little dizzy. Liu Shi held his breath and stepped forward to check, the silver substance could basically be determined to be mercury, and he had done a lot of homework before coming to the underground palace, and he had a certain understanding of mercury, and he believed that the judgment would not be wrong. Due to the temperature in the corridor, and there is very little mercury, it is only covered with a thin layer on the ground, and the content of toxic gases in the air is very small, and it will not cause any harm if it comes into contact with the skin, as long as it is not too long, so Liu Shi dared to stop and check, and he didn't even need to wear a gas mask.

In the legend of the underground palace of the Mausoleum of Qin Shi Huang, there is a large amount of mercury, and a gas mask is also prepared for this purpose, but no trace of mercury has been found after entering, and I did not expect to find it in this unknown place. There is too little mercury here to prevent tomb robbers, so what is the purpose of this small amount of mercury here?

Liu Shi took off the small shovel and dug down at the position of the mercury, only to dig about ten centimeters, and found that the content of mercury increased significantly, and it seemed that a layer of mercury on the ground of the tunnel seeped out from the ground. Digging down continuously, Liu Shi's guess was verified, but as the depth increased, the mercury smell in the air became more and more intense, the poisonous gas became bigger and bigger, breathing became obviously difficult, and his head was a little dizzy. Liu Shi wanted to clean up the mercury, but now was not the time, so he had to give up the excavation, immediately put on a gas mask, and continue to walk towards the front of the road, if he didn't go, the situation would get worse and worse.

Walking forward quickly, I have not encountered the trap, or to a certain extent, there is a degree of relaxation, with the increase of mercury in the air, the speed also increases, and when I suddenly see that there is a dead end in front of me, my mind is suddenly shaken, and suddenly I step on the air, and the whole person loses balance. Liu Shi's reaction was not unpleasant, the first reaction was to encounter the trap, quickly flipped his body, and at the same time supported the trap wall with his right hand, the whole process was completed in one go, and he rose into the air with incredible difficulty, and then rolled to the side, out of the trap range.

The whole process happened in a very short period of time, although Liu Shi was able to escape, but the palm of his right hand was cut, the blood kept flowing, he didn't care about carefully bandaging the wound, wrapped it in clothes at will, and immediately went to check the trap, a deep pit three meters deep and about one meter long and one meter six wide, except for the soil, no other sharp weapons were seen, like a naturally collapsed pit. This is already an underground palace, at least hundreds of meters underground, how can there be a collapse? Liu Shi immediately thought of a possibility, that is, under the Yongdao, there was an underground palace, and due to the previous earthquake, there was a collapse here, so there would be a subsidence, instead of encountering a trap. Liu Shi observed the surroundings and encountered a dead end again, and the location of this subsidence may be the only way out.

Thinking like this in his heart, but Liu Shi will not choose to fall into this road for the time being, now he is sure that there is no danger for the time being, he needs to solve the injury of his right hand first, there is a medical bag in his backpack, and he will take some hemostatic medicine first, if there is too much blood, the person will become weaker and weaker. When taking medicine, Liu Shi found a strange phenomenon, at the end of the Yongdao, the Yongdao is actually round, there will never be such a deviation, there is only one possibility, the end is round, it is specially designed, what special meaning will it have? Or is it just a random change, just to confuse the tomb robbers who enter the dungeon?

Doubts kept appearing, and Liu Shi also had no intention of bandaging the wound, seeing that the blood on his right hand had stopped, and there was no bandaging for the time being, he began to carefully search the end, hoping to find some clues. Thinking like this in his heart, there was really a clue, and suddenly the top of his head collapsed, and the stone fell, but fortunately, Liu Shi maintained enough vigilance and dodged at the first time, but he was scratched by some small stones. After falling a part of the stone, it quickly calmed down, Liu Shi breathed a sigh of relief, and at the same time felt a little surprised in his heart, because some cyan spots appeared on the top of his head, and if he looked at the spot carefully, it was not a stone, and there should be something hidden behind the stone. This is definitely a clue, Liu Shi even thought that all the stones above his head had fallen, and he could fully see what the cyan thing was.

This time the idea came true again, the stone above the head began to fall again, I thought that I had avoided the falling rock, and it was safe, Liu Shi didn't expect that he would come whatever he wanted, so he could only continue to dodge, but then his feet began to vibrate again, shaking so badly that it became difficult to even stand firm, and at the same time, with the vibration, the falling rock intensified, compressing the space for dodging, and there was a deep pit behind him, and he was hit many times by the falling rock in a short period of time, and the only thing he could do was to try to avoid being hit in the head. Many stones with sharp edges and corners, special clothes can not avoid damage, were hit several times, when I thought it was a desperate situation, at this moment, a ray of light appeared, not the flashlight in Liu Shi's hand, but from the top. Liu Shi looked up, the light from above was a little dazzling, but he saw a vague shadow, as if it was a human leg, was there someone on it? There is also light coming, could it be Han Wei and them? Thinking of this, Liu Shi was excited in his heart and hurriedly shouted, but the dust was everywhere, coupled with the impact of falling rocks, the shouting was extremely weak.

The time is too short, I can't see anything more, the vibration continues, and even the body can't be stabilized, how can I have time to observe, and the shouting can't be far at all, Liu Shi can only play up twelve points to avoid falling rocks, only when people are safe, they can only be useful when they see Han Wei. The falling rocks quickly stopped, the vibration quickly disappeared, Liu Shi was finally able to stabilize his body, his body was already scarred, and he didn't care about the injuries of his body at all, and immediately called out Han Wei, Li Hua, Lin Xue, and the continuous shouts were not answered, the light projected from the top before was still there, and a bronze round object could be seen, which was actually volleyed, and then looked at the bronze round object below, and it was a bronze product, and the two had a distance of dozens of centimeters, Liu Shi guessed whether it was a tripod, a huge bronze tripod, and the tripod cover was pulled up. Liu Shi didn't know that the speculation was close to the truth, and he was only thinking about how to leave, not only to leave safely, but also to solve many mysteries, but also because he was eager to join Han Wei and the three of them as soon as possible.

There are many stones falling around, layer upon layer, forming irregular steps, climb up along the steps, you should be able to climb out, so you act immediately, the process is very smooth, when you are about to reach the top, the left hand first buckles the edge of the tripod, which is stained by mercury, exuding a silver light, and the right hand is full of blood stains, in a special environment, it is particularly eerie. Liu Shi naturally didn't know, so he almost scared the fat man to death, thinking that he had encountered a ghost, and finally fainted.

Liu Shi didn't see Han Wei, Li Hua, and Lin Xue, at least he saw Han Tian and the three of them, waiting for the three of them to wake up, asking about the specific situation, so he had to wait in the palace, and tried all kinds of methods, but they couldn't make the three of them wake up, Liu Shi didn't have the mental power, the only thing he could do was wait.
