After carefully checking around one side, Yushan found that there should be a passage here connected to the outside. If the predecessors came down from the vertical shaft nearly hundreds of meters underground, they took a torch, and then climbed into a small pipe hole that was difficult to find, and it would be almost impossible to come to this place.

And no traces of torches were found along the way, only in this hall.

This makes people feel very confused. Even if they climb to the top of the slope, Yu Shan was still unwilling to give up. There seemed to be room at the top of the front, but it was very dangerous in the past.

After giving Qian Xiaohao a few instructions, Yu Shan lay on the cliff and slowly cut across.

Qian Xiaohao looked down at him, unable to protect him. He was a little worried and kept reminding Yu Shan to pay attention.

If you accidentally slide down in such a place, the result will be very miserable.

There is also a steep slope in front to lie up, without any grasping points. Fortunately, there is a rock wall opposite the slope, which can be supported by hands, then pedaled by feet and moved up carefully.

After climbing to the top, Yu Shan was immediately shocked because there were many large bats piled up at the entrance of the cave.

After taking a closer look, it seemed that all the bats were dried up. Yu Shan touched them with his hands, and sure enough, they were all dead.

"This is not a bat cemetery, right?" I thought of the pangolin's tomb I discovered, which is very similar to that here, but one is deep underground, and this one is indeed on a cliff.

After rummaging through for a while, it was full of dead bats. Yu Shan collected two of them intact and put them in his backpack, so he didn't look at them anymore.

After wandering around for a few times, I found that this small hole was just a dead hole, and it was not the path to enter the hall below.

In order to determine whether it would be a collapsed passage, Yushan used a lighter flame to glance at the small holes around him. The flames stood up, indicating that there was no air flow, and there would be no space opposite the holes, and there was no access here.

After wandering around for a long time, Yushan discovered that this hall was a confined space. If the bats lived here, I didn’t know which exit to fly out.

If he couldn't find it, Yu Shan stopped searching and he returned along the same path.

Qian Xiaohao went to the top space at the edge of the cave hall. When Yu Shan rushed over, he was hanging in the air on a cliff, feeling dangerous to go up and dangerous to come down.

Qian Xiaohao said: "If you work hard, you can climb up here."

But after climbing up, he couldn't get down without a rope, and Yu Shan couldn't pick him up and could not help him.

In this way, Qian Xiaohao will be trapped at the top of the cliff in the cave hall. Unless there is really a passage leading out there so that he can get out, he will be trapped on the top of the cliff in the cave.

Yu Shan carefully observed it around. At the corner of Qian Xiaohao's cliff, there was a sharp small crack corroded by water. The cliff outside the crack turned out to be an empty shell, like a piece of paper.

People lie on it but can withstand it. This gap is at a 90-degree angle to the cliff next to it, but Qian Xiaohao said that he had climbed over just now and it was difficult to climb up and could not climb up.

There are many sharp stone blades under the cliff that stand like a knife edge, which seems even more dangerous, but Yu Shan wants to give it a try.

The empty rock wall in this gap can be grasped with hands, and the feet can be pushed between two vertical cliffs. The rock wall is a wall flowing stone, with great friction. When you stick the body on it, its friction force hooks people like a barb.

In this way, Yu Shan's body was close to the rock wall, his hands and feet moved up little by little, and climbed up the steep cliff step by step.

Qian Xiaohao looked nervously below and told him to be careful that he could not protect such terrain below.

Yu Shan was also very nervous. He knew in his heart that at such a height, there was a stone blade stretching up like a knife at the bottom of the cliff, and he must not fall down inadvertently.

At the top of the cliff, there is a small cave hall as big as a bedroom. If you climb up a few meters, the cave will end, but there is still no access.

It seems that there is really no access in this hall, so where did the charcoal ash from these torches come from?

The two returned to the bottom of the hall and followed the traces of the water to the top. What was strange was a downward cave.

"I know here that leads to an underground cave where there are many pangolins." When I saw the downward cave, Yu Shan knew where it was.

At this time, Yu Shan discovered that the hall where they were wandering around just now was actually separated from the place where they discovered Ye Mingsha, which was separated by a wall, so a bat tomb appeared there.

And here is the pangolin's tomb underground. All this does not seem like a coincidence, but rather it seems to be a deliberately arranged by someone, because one is air-dried and the other is a cold storage that can be reused.

Yu Shan led Qian Xiaohao to the underground tomb of the pangolin and saw the pangolin buried there.

"Can these pangolins be eaten? At least these scales are still useful." Qian Xiaohao fiddled with the corpses of the two pangolins and found that the scales are still bright.

"Be careful, these scales are not only useful, but also sharp." Yu Shan reminded Qian Xiaohao that he had seen with his own eyes how the living pangolins hunt.

Looking at the erect scales, Qian Xiaohao touched them.

"Ah!" Just by accident, a small hole was cut in Qian Xiaohao's hand.

"I have reminded you a long time ago." Yu Shan complained.

After helping Qian Xiaohao bandage the wound in a hurry, the two of them focused on the pangolin again.

"These pangolins have turned into jerky meat, and their muscles have contracted, so the scales are standing like a knife, right?" Qian Xiaohao used the flashlight in his hand to pull a pangolin.

"Living bats and pangolins should be able to eat, but dead ones may not be the case." Yu Shandao.

Qian Xiaohao looked at Yu Shan in surprise and said, "Have you seen a living person?"

Yu Shan nodded and said, "I have seen pangolin hunting bats, and I took two of them with me. We went to other places to check it out. I found that the area of ​​this underground cave is not very large. We are just wandering around within a certain range."

Each of them put a pangolin away and put it in their backpack, and walked out of the cave again.

"We definitely haven't walked this road here." Climbing back into the hall, Qian Xiaohao used the compass to immediately determine an unknown route.

This cave is only as big as a human, tilting downwards about 60 degrees, reaching below the ground, with the opening and the hole covered with damp silt and sand.

From the traces of the flowing water, it can be seen that during the rainy season, water rises from the ground along the hole, but there is no artificial garbage around, which means it is not connected to the flowing water outside.

Will it lead to another space outside the cave? That is, the original owner here comes into the cave.

The cave is too small, full of damp mud and sand. Qian Xiaohao was unwilling to climb over, so Yu Shan decided to go over and give it a try.

Yu Shan brought a shovel and had to shovel some of the sand so that people could enter. They had to lie flat before they could slide down by themselves. Otherwise, they would be stuck, but they could not lie flat completely. Otherwise, the whole person would be slid into the hole, and there was a deeper cliff or a deep pool under the hole, which was unknown.

For safety, you must hold the top of the cave with your hands and control the speed of your sliding down.

When Yu Shan had just gone down for a while, the damp mud and sand were all drilling into his clothes and into his body, and it felt very uncomfortable.

Yu Shan hesitated for a moment and decided to give up. Judging from the cave, there should be a pool below it, because it is only a 3 or 4 meters high drop from the water surface of the cave outside, so it is impossible to get through to the bottom.

I just found a reason for myself. Yu Shan left and didn't want to make it too painful. If I really want to check here, at night, my soul will come out of my body and check it out.

The two crawled out of this pipe cave and returned to a quiet pool at the uppermost stream of the Yin River. The water flowed very slowly and looked like a pool of stagnant water.

Yu Shan tried many times and did not find any creature in the pool. He thought to go down to explore the end of the pool, and whether there was still a passage.

Walk a few meters forward and the water will flood your hips. You can climb a rock through the cliff above the pool, but it still cannot reach the end.

It seems that I can only swim past. The weather is a little cold in November, and it is even colder here. The water in this cave flows in from the cave. Its water temperature is the temperature on the surface, which is really cold.

Qian Xiaohao took off his clothes, Yu Shan tied the auxiliary rope he brought to his chest and tied it to the other end on the mountain. Because the mountain pulled the rope, Qian Xiaohao slowly put the rope while swimming. If there was danger, Yu Shan pulled the rope and pulled him back.

This reminded Yu Shan of the movie that it was a skeleton frame when pulled back. If that were the case, Qian Xiaohao would be in a miserable state.

The water was so harsh that Qian Xiaohao jumped into the water and thrust a few times and shouted that he couldn't stand it. The temperature here must have reached several degrees below zero.

Yu Shan carefully placed the rope, keeping it not tight or loose, observing his movements, listening to his movements, ready to pull him back at any time.

Qian Xiaohao swam to the end. The pool turned two bends, and there was still a dead hole at the end. It seemed that the space of the cave was under the water and you had to dive before you could pass.

Back to the bottom of the sinkhole, we came to the Yin River with mud and sand, and the river that bounded the Yin River without mud and sand.

Several huge stones blocked the river channel. The river channel hid behind the stone wall and could not see its waterway.

The flashlight shone in from a gap between two huge stones. Opposite the river was a wide watery beach. The flowing water was not obvious and the direction of the water flow was not visible.

There is a space along the middle of two huge rocks that can go down to the river, which is very deep silt.

Yu Shan judged that there would be Yinhe opposite, so he could not give up this time.

Yu Shan was walking in front and Qian Xiaohao was walking behind. As soon as the two of them walked a few steps, the mud fell to Yu Shan's buttocks, and there was no solid ground under their feet, and the sinking mud was still there.
