When Yu Shan wanted to pull out his other leg, the speed of sinking accelerated.

Yu Shan is sinking very quickly, if it weren't for Qian Xiaohao behind, maybe Yu Shan would have disappeared here.

Qian Xiaohao's eyes were quick, and when he saw Yu Shan sinking rapidly, he immediately pulled Yu Shan out.

"If only one person is stuck in the quagmire, how can he save himself? It's like a swamp, it's dangerous. "Yu Shan's heart has palpitations.

"Let's go! Get around here. Qian Xiaohao was also in a cold sweat, he had been going smoothly for the past two days, and he had forgotten that there was still danger.

"Wait, I seem to have stepped on a low just now, otherwise you wouldn't have been able to pull me in." Yu Shan recovered for a moment, and immediately grabbed Qian Xiaohao, who wanted to leave.

"Stepping on the end? It doesn't look like it's very shallow. Qian Xiaohao said with a look of disbelief.

Yu Shan looked at the quagmire and said thoughtfully: "But I did step on a hard thing." ”

"Dig it up and see, it's not difficult anyway." Qian Xiaohao immediately made a decision.

Qian Xiaohao took out a folding sapper shovel from the side of his backpack, packed it up, and immediately excavated.

Yu Shan also had one on his backpack, and the two of them were on the edge of the quagmire, slowly cleaning it up, and in just ten minutes, a cross-section was dug up.

"This is a soft-shelled turtle? Haha, your luck is the same as stepping on ****. Looking at the things curled up in the mud, Qian Xiaohao immediately laughed.

"It's not just a soft-shelled turtle, what do you think it is?" The place where the mountain was dug forward is a little ahead. There's a lot of water oozing out of the mud.

Looking at the pale yellow thing that meandered and swam in the mud like a snake, Qian Xiaohao said in surprise: "Yellow eel? ”

Yu Shan shook his head and said, "It's not Huangshan." It's a loach, the same thing we saw yesterday in that pool. This thing has a lot of jumping ability. ”

"Such a big loach?" Qian Xiaohao was a little surprised.

Yu Shan said: "I'm curious, what are these loaches doing in the mud. ”

"It looks like hibernation, but the loaches in the waterhole over there are alive." Qian Xiaohao is also a little strange.

Yu Shan looked around and said, "Maybe the environment here is different, dig it again, maybe you can find a soft-shelled turtle, catch a few more, and you can make money this time." ”

The two dug for another ten minutes, but this time they didn't find any soft-shelled turtles. Instead, they caught a lot of grass shrimp trapped in small puddles of silt, and the size of these grass shrimp is not small, the smallest one is more than ten centimeters long, and it is absolutely big.

In this way, the soft-shelled turtle was not found, and a few catties of grass shrimp and more than a dozen loaches were found.

There was no more to gain, and the two of them could not continue digging.

"Get over here and move on." With a little gain, the two of them can't give up halfway.

There was no way, the two of them could only lie down. Press down on the mud with your chest, arms, and entire body area, lift one leg up, then pull the other out, and then hold this position. Swim yourself out like a swim.

Anyway, it's covered in mud, so it's not bad to crawl over it like this.

Bypass the boulder. Go straight to the pool from the upstream and go down the waterway. Soon the two of them entered a wide beach.

The water in the pool flooded to the waist, and it was bitterly cold. Luckily, it won't be like a quagmire that keeps you in and out.

The cave in front of me was relatively low, so I had to go over it with my waist, and after a while I reached the mudflat, and entered the muddy area where the thighs were buried.

At the end of this tidal flat, another river was found, which flowed quietly, and there was no sign of it at the position next to the boulder just now.

However, Yu Shan found some aquatic creatures under the water, including loaches, grass shrimp and some small fish, and there were not many of them, and Yu Shan would not make a fuss.

Continuing to move forward, there was indeed another underground river, which confirmed Yu Shan's original judgment.

The silt of the Yin River is very low, the highest point is less than a meter high, and the thick silt buried in the ground makes it even shorter.

It is painful to walk in the mud, unable to straighten up, with a cat bent on the waist and supported by hands in the mud of flowing water.

I was so tired that I had to lie on my stomach or kneel in the mud to rest, this damn low hole, it had always been so short, and it was getting shorter and shorter.

The two of them had climbed many holes, and they had also climbed very low water holes, but it was the first time they had climbed very low holes, and the ground was still full of silt and flowing water.

Sometimes, it was so short that his face was almost touching the water, and after walking forward for a long time, there was no sign of the cave space getting taller.

On several occasions, the quagmire suddenly became so deep that it almost submerged to the waist, and they had to be in front of one person, making sure that after fully stepping on solid ground, the other person followed, and the first person was trapped, and the latter pulled him out.

Therefore, when exploring, wisdom is more important than knowledge and skill, if the two of them are reckless men with only spinal cords and no brains, they may both sink into the mud and wait for destiny.

There's a section in front of you, and the silt is deep underneath, but the surface of the silt is stronger, so it's fun to walk fast and trot over it.

But if you are not careful, you will step on it, and the whole person will fall into the quagmire, Qian Xiaohao's weight is relatively heavy, and the mud shell can't bear it, and they have to cross to the opposite side, because the mud is too deep on this side, and they will be trapped in it.

The two of them tried it for a while, and finally came to the conclusion that kneeling on it would bear a larger area, and they would not fall into it.

Qian Xiaohao then knelt on the mud shell, and when he knelt on one leg and was about to exert force on the other leg, the mud shell suddenly broke, kneeling him into the mud, revealing a head on it.

Yu Shan was nervous, and he stepped on the solid ground under his feet, and both of them couldn't help laughing, such a wolf bèi, it was really funny.

It was very difficult to walk and dangerous, but they gritted their teeth and finally reached the end of it.

It suddenly became a very high space, even as if it was the bottom of a shaft, but if you look closely, you can't see the outside space from the top.

The cave ended in this very high and narrow hall, and the water came from the bottom of the rock wall, which was also the underground flow under the cave, and the mud and sand were so buried that even diving could not exceed the height of a person's space.

"Have we been to this place before?" Seeing this shaft, Qian Xiaohao was a little stunned.

Yu Shan smiled and said, "Aren't you the best at determining the direction?" ”

Qian Xiaohao immediately took out the location map he had drawn, and laughed out loud after a while.

Seeing that the entire drawing was connected, Yu Shan knew that they had indeed walked through all the caves that could be passed underground.

The complete cave map was drawn, and the two of them could clearly see that the entire cave system should have been explored by them, and there may be some small branch caves that they hadn't walked to, but the main cave, they must have walked through, which made the two of them feel very relieved.

Their expedition was also a success, solving several doubts and gaining a lot, but all of them were local products.

It was still about six o'clock in the afternoon, and neither of them wanted to move anymore, so they decided to go out tomorrow and have a good rest in it tonight.

Yu Shan and Qian Xiaohao's clothes and shoes were all thick mud, and they didn't have any clothes to change, so they took a bath in the Yin River to wash clothes and shoes, which was too difficult to wash, and they washed for more than an hour.

It's better not to wear soaked clothes, put them aside, and cook naked.

It's still too cold, and I have to run on the rocks while munching on compressed biscuits while keeping warm, and I can't lose my temperature here.

Pang Tong, who stayed outside the cave, was too caring, and threw a lot of roasted sausages for the two of them, and fell on the pile of human bones.

However, the bag containing the cake in mid-air was smashed apart by the rock wall, and the two men searched for a long time and only found two, and one of them could not be found, and one of them fell on the human bone.

The two-story pile at the bottom of the shaft made Yu Shan curious, and there were human bones, a lot of stones and dirt inside.

Qian Xiaohao didn't want to touch these things, and the bones of at least 70 people were buried here.

Yu Shan didn't have any scruples, he decided to dig it and see if he found anything.

Qian Xiaohao had already gotten into his sleeping bag, he didn't have a good rest last night, and he planned to sleep well today.

Yu Shan thought about digging up two skulls and placing them next to the head of his sleeping bag, and when he woke up in the morning, he would suddenly find a skull on one side, which must be very funny.

It seemed that the rain was falling on the shaft, and on this pile of human bones, rubble, and other earth, tree branches and leaves, etc., Yu Shan searched all over with a strong flashlight, and found only human thigh bones and some pieces of pig iron.

In addition, a snake was found, which seemed to be hibernating and did not move when touched, as well as a few spiders, as well as centipedes and scorpions, so it can be said that there are all five poisons here.

After digging with a sapper shovel for a while, Yu Shan knew the hard work of archaeology, and this sapper shovel dealt with the stone piles here, as if he was cutting down a big tree with a pencil knife.

After digging for a long time, there was no progress, and Yu Shan had no patience, and he originally wanted to go out of his body to explore, but thinking of all kinds of strange animals here, Yu Shan also let go of this thought.

It's not too early, it's time to go to bed.

After getting up in the morning, continue to eat compressed biscuits, it is really difficult to swallow, drink water and pour it down, and it is vomited out, and then swallow it back, you must eat more, and the climb back is very difficult to consume physical energy.

After talking to Pang Tong, who was staying on the ground, Qian Xiaohao carried a bag on his back and hung a reloaded rope bag, and went on first.

Yu Shan closed the rope, and finally went up, when Qian Xiaohao was rising, Yu Shan left the mouth of the shaft, closed his eyes alone in this silent underground cave, and listened carefully to the movement here.

Without the disturbance of the outside world, any sound that happened underground seemed to be amplified countless times, and it was heard clearly by Yu Shan.

The sound of running water, the sound of water droplets falling into the water, and even the sound of a dog barking, if you look closely, you can even hear someone singing and moaning in the depths of the cave.
