I helped Xiao Lei to Sun Ping and Xiao Tian, who was busy filling Dr. Chen. Dr. Chen's eyes were closed, his face was gray, and he didn't know where his glasses had gone, but his lips opened and closed slightly, and he should still be saved. I sat down next to him and reached out to feel his pulse, which was a little weak, but strangely enough, there was a fainter pulse, beating much slower than normal. This condition usually only occurs in pregnant women, but it is completely impossible for Dr. Chan.

I looked at it carefully, in addition to beating slowly, it is still very different from the pulse of a normal person, not so much beating, but like the waves gently lapping on the beach, one advance and one retreat is very regular, if it is a wave, it must be at high tide, obviously the strength of the ashore is greater.

I didn't have time to think about the reason, so I took out a reassuring pill from my body, poured out a red pill from the compartment of the brocade box, handed it to Sun Ping, and motioned for Sun Ping to give it to Dr. Chen. I remember Dr. Chen telling Xiao Lei that there were signs of liver and spleen poisoning in the pulse of the spontaneously combusted miner, which may be the situation I encountered in front of me. Cinnabar Baidi Pill is a medicine that refines more than a dozen flavors to dispel evil and ward off poison, which can effectively block the erosion of internal organs and blood by toxins. I don't know if it's going to work, but I really don't have a better way at this point.

"Xiao Lei, how is your health? What is the abnormality? Tell me what happened?" I settled Dr. Chen, although I was also anxious to go into the depths of the tunnel and find the Cao team in the depths of the essence, but reason told me that I still had to listen to Xiao Lei after introducing what happened below, especially how they met with Dr. Chen, and then go in to save people to be more sure.

Xiao Lei sat down beside me and leaned against the cave wall, his face was pale, and cold sweat was dripping, but he still spoke with great spirits.

Xiao Lei, Liu Xiaowu, and Lao Qin climbed along the tunnel all the way in, and after turning the right-angle bend, they found that the walkie-talkie was interfered with, and when they reached the cave blocked by Dai Mine Chief and his gang, they could hardly receive signals from the outside world. They had planned to turn back and get in touch with the outside first, but Liu Xiaowu found that the only filling that blocked the cave was that the outer side was blocked with some large stones, and the inside was all loose slag and soil. began to clean up with a sapper shovel, and everyone discussed digging through the tunnel and then calling the Cao team to come down.

Unexpectedly, the blockage was cleared very smoothly, plus Liu Xiaowu and Lao Qin were both experts in this area, and in less than ten minutes, they had cleared the cave that could accommodate a person in and out.

Liu Xiaowu was the first to get in, and arranged for Xiao Lei and Lao Qin to clean up the cave and explore it first. At this time, they suddenly found that after the cave extended forward for dozens of meters, a two-way intersection appeared, and one of the forks revealed a faint light.

Liu Xiaowu and the others guessed that this must be Dai Mine Chief's people, and they didn't have time to turn back and call Cao Team for them, so the three of them chased down the bright roadway.

Xiao Lei said this, I asked him, that fork in the road, do they go on the left or the right?

Xiao Lei thought about it and said it was the right side. At this time, I knew in my heart that the two groups of us here had embarked on two different paths.

Xiao Lei and the three of them walked all the way down the fork on the right, and they didn't go far before they found a bunch of bonfires in the middle of the roadway that had not been burned out, and it seemed that they had not been trampled on for a long time.

Sure enough, after walking a few steps forward, I found a one-person high and more than two meters deep hole on the cave wall on one side, which contained food, water, and tools, and the key was that half of the space was used to pile large and small black stones, which were much heavier than coal, but they were crystal clear. Although Xiao Lei has never seen coal essence jade, he has probably guessed what these things are after listening to us talk about them before.

Several people were extremely excited, ignoring the potential danger, and accelerated their pace to chase all the way.

After walking not far away, there was a three-way intersection in front of him, this time, Xiao Lei really made a difficulty, lying on the ground and searching, hoping that Dai Mine Chief's group of people could leave some clues on the road, so that he could make the right choice. It's a pity that the ground is full of chaotic rocks, and Xiao Lei didn't make any useful discoveries.

Liu Xiaowu, on the other hand, took out a palm-sized, bowl-shaped metal funnel from his backpack, put it on the stone wall and listened carefully, and then leaned on the ground to listen to the laneway, so that he listened to the three forks one by one, and finally confirmed that it was the leftmost one according to the size of the footsteps he heard. Xiao Lei immediately understood that this was an ancient method of listening to the sound and asking for directions, but it was strange how Liu Xiaowu could be so well prepared.

On the way, Liu Xiaowu told Xiao Lei that this is a necessary tool for his cave exploration, which can mainly identify the location of underground water flows, mountain cavities in the lava terrain, and can also find some hidden passages through the sound of underground animals marching.

But after all, every time they arrived at an intersection, they had to stop and listen to it, and the speed was greatly reduced, even though the three of them kept speeding up, but after walking out for more than ten minutes, they lost the footsteps that had been helping them identify the laneway.

This time, Xiao Lei regretted a little that he left in a hurry and did not leave some marks on the way here. But Liu Xiaowu told Xiao Lei that along the way just now, the sound he heard from the metal funnel, in addition to the faint sound of footsteps, there was also a sound similar to the waves tumbling, but it was different from the underground river he had encountered before, he really couldn't figure out what it was, but it was obvious that the previous footsteps were towards the strange sound, indicating that it was the direction of Dai Mine Chief's goal. Now, although the footsteps are gone, the strange sound is still there, as long as the strange sound is getting louder and louder, it proves that the general direction is right. It's just that judging the fork in the road is, it won't be so accurate, and it may take some wrong paths.

The three of them continued to walk forward like this, and Xiao Lei didn't dare to be careless at this time, and began to leave some marks on the rock wall of the tunnel he passed.

They walked for more than ten minutes, and Xiao Lei found that the temperature in the alley was getting higher and higher, and the oxygen content was getting lower and lower, so everyone had to slow down the speed of progress, and Liu Xiaowu's brows were also screwed together. He took out an instrument and looked at it, telling Xiao Lei that the depth was almost a hundred meters now. Lao Qin advocated that we hurry back, because this depth far exceeded the depth of the test mine, and we did not see the transfer platform, nor the shaft, and we did not argue the direction, so we must have taken the wrong road, and Bao Buqi had already entered the mine of the Ming Dynasty.

The old mine of the Ming Dynasty is said to have the roadways below that no one can figure out the path at all, and it is inevitable to get lost in it without a map, and it is difficult to get out again. Liu Xiaowu was also very hesitant, after all, the footsteps had disappeared, and no one knew where it would take us just by relying on the direction of the strange sound. In particular, the increasing temperature and humidity of the underground and the rapid reduction of oxygen levels carry significant risks.

Xiao Lei and the others were discussing the next step of advancing and retreating, when suddenly the miner's lamp above their heads, the flashlight in their hands suddenly emitted a dazzling white light, and then with a burst, the alley was dark.

All this came so suddenly that everyone froze in place, Liu Xiaowu and Lao Qin were busy looking for spare flashlights from their backpacks, but Xiao Lei lost his sense of direction in the dark. He had just put his backpack on the floor of the alley a few meters away from him, when he felt the rock wall in the darkness and took a few steps forward. He didn't expect his feet to suddenly empty, and if he wanted to adjust his posture again, it was too late, and all he could reach was the smooth rock wall, and he rolled into the endless darkness with one heel.

Little Thunder rolled down in the darkness. This hole is at the bottom of the tunnel, the diameter is not large and it is very hidden, so the people who have been hurrying forward did not pay attention. Fortunately, this hole is not straight up and down, Xiao Lei knew that he couldn't stop himself from slipping, so he simply curled up, protected his head with both arms, and let gravity fall and roll him, trying to reduce the damage. Rao was like this, rolling down on the hard stone floor, and it still made him feel like he was falling apart.

This cave extending diagonally below is nearly 100 meters long, very steep, and when Xiao Lei was stopped by the wall at the end of the cave, he was covered with bruises, and his ribs were painful for a while, and it was estimated that one or two were broken. When he was leaning against the cave wall panting, Liu Xiaowu above turned on the flashlight and shone on the position where Xiao Lei was. Seeing that Xiao Lei could still move his body, Liu Xiaowu and the others were relieved.

But the slope was too steep and it was difficult to climb down, so Liu Xiaowu asked Xiao Lei to wait below, link the rope he carried with him, find a place to fix it, and then come down to save him.

The bottom of this stone cave is connected to two lanes, Xiao Lei did not have any lighting tools in his hands, and he was injured, so he had to sit down in place and wait for Liu Xiaowu and them to come down. The oxygen level at the bottom of the cave was much lower than above, and the air was filled with the smell of sulfur, and Xiao Lei's breathing became heavier and heavier, and his brain began to fog.

(Husband, infinite quantity, endless time, impermanence, no reason.) Therefore, the great knowledge is far and near, so the small but not the little, the big but not the much: the knowledge is infinite. Prove to the present, so far away but not boring, but not staggering: know the time endlessly. Observe the surplus and void, so the gain is not happy, the loss is not worried: the impermanence of knowing the difference. Knowing and being frank, so life is not spoken, death is not a disaster: knowing the end of the beginning is not a cause. Counting what a man knows is not as good as what he does not know, when he is born is not as good as when he was not born, and seeking the greatest domain of his smallest, he is confused and cannot be satisfied. From this point of view, how can we know that the slightest is enough to determine the fine, and how can we know that the heaven and earth are enough to be poor to the great domain --Zhuangzi)
