Mr. Mao's analysis is like this, and I have thought it a little more thoroughly. Pen? Interesting? Pavilion wWw. ｂiquge。 infoIf these cavemen are really highly intelligent human beings, they live in this isolated cave basin, and what do they do most of the time except to solve the problem of food and clothing? Go to bed? Idle?

There is neither Wi-Fi nor books here, even if the old cavemen have many stories, there is a day to finish them, if the average age is 60 years old, in these 60 years, in addition to eating, sleeping and telling stories, what are they spending the rest of their time for, except for the length of life, how can they live the breadth of life in this claustrophobic space?

There is no doubt that if they really master a certain spiritual method, then they will definitely spend the rest of their time cultivating. The source of food is relatively stable, and the rat factory does not consume their manpower and material resources at all, they do not need to cultivate, only harvest, then, they must have a lot of time left, it is impossible to sleep all of them, they always have to find something to do, no matter who they do, they will go crazy.

I said to the people,

"It seems that the cavemen here have really mastered some spiritual cultivation methods, but being able to cultivate to the extent of penetrating the wall sounds very terrifying, and I don't know, what other magical skills have they practiced through spiritual cultivation? However, I think that there must be only a few people who can control the technique of piercing through the wall, otherwise, why would that palace still have a door, just leave a wall! ”

Yang Xue said:

"Not necessarily, we don't know the exact age of the construction of the palace above, but it shouldn't have been built recently, because without the aid of any tools, how could such a magnificent crystal palace be built? That must be a very distant thing, so far away that this underground river has not yet been submerged, could they be the descendants of those ancient absenteeism? ”

I said that this possibility is not impossible, those few mines have a history of at least hundreds of years, maybe because of the sudden surge of the underground river, so that a large number of miners were trapped in this cave, they had to enter this underground basin to breed, and later in order to resist the threat of the bat people, the use of mining tools, after decades or even hundreds of years of efforts, built such a huge palace, it seems that the structure of this palace is not as simple as we seem, in the underground of the palace, There should also be a very complete living area, and those cavemen may live in underground palaces.

Boss Chen pointed to the wall and said:

"What should I do? Do we still want to save Xiao Li? If he dies, how will I explain it when I go back? ”

I was about to ask Boss Chen what to explain, but Mr. Mao suddenly stood up and said:

"We don't have any tools at the moment, and we're running out of explosives to break down this wall, so I think we'd better go up first. The so-called Taoist nature, spiritual cultivation is such a thing, it is originally one with all things in heaven and earth, using the mind to control one's own energy, if these cavemen have really cultivated to a certain height, we had better not provoke them. ”

I was curious, so I asked Mr. Mao about spiritual practice, is it easy?

Mr. Mao shook his head and said, "It's difficult! Not to mention the cultivation of the realm of the unity of heaven and man, even the simplest cultivation of Buddhism is extremely difficult, and it cannot be done by a monk who has attained the Tao. ”

I said how hard it is to die, isn't it death? No matter how difficult it is to die, I can do it in minutes.

Mr. Mao glared at me and scolded: "The kid doesn't understand, he dares to make a big fuss!" This Buddhist family passed away, but he killed himself with his mind, you try? ”

I couldn't help but be taken aback when I heard this, and said in my heart that I would kill myself with my mind, how could such a thing be done?

We didn't dare to argue any longer, and for now we had to go along that passage and see if we could find a way to get Captain Li out, if he was still alive. However, Yang Xue said that this water eye of the rat's nest is very likely to be connected to the underground dark river, and if we really can't find any trace of Captain Li, we can dive into this water eye and maybe find a way out. We all nodded in agreement, and we didn't dare to hesitate, and followed the rope back down the hallway, rested a little, and continued along the dark path.

This cloister is like a tombway, very neatly repaired, and each crystal brick is also made to a well-proportioned size, if only simple tools are used, how much time and effort will it take?

I didn't go far, and I found the same room, and there were several similar farms, and it seemed that the number of cavemen here would not be small, otherwise how could they need so much food.

On the wall of the passage, at intervals, there was a torch placed diagonally in the wall, which we lit in turn, and the passage was illuminated by the fire. We went down two more stairs along the passage, and did not find any secret passages that led to the ground, but in a semi-artificial cave, we found a shaft, the diameter of the mouth of the shaft was two meters away, narrow and deep, and there was no end in sight when we used a flashlight.

The walls of the shaft are extremely smooth, however, at intervals there are protrusions on each side that can be climbed to settle down. We discussed it, and Mr. Mao volunteered to go down and take a look, this shaft seems to be the residence of the cavemen, and they usually enter and exit through this shaft. We persuaded him that this shaft was too narrow and it might be dangerous to go down rashly, but Mr. Mao insisted on going his own way, and seemed to be extremely worried about the safety of Captain Li's life, and he didn't know what their relationship was in private.

We tied the rope and slowly put Mr. Mao into the shaft, I watched his thin body slowly disappear into the darkness, the light of the headlamp became more and more dim, and an ominous premonition rose in my heart, this place is too fucking weird, and I don't know if those cavemen are cannibals, not interested in human flesh?

When the rope was put down 50 meters, Mr. Mao suddenly stopped, he pulled the rope, opened his throat and shouted to us:

"There's a side passage down here, it looks very deep, I'll go in and have a look!"

Before we could stop it, Mr. Mao untied the rope tied to his body and entered the passage sideways, and in the blink of an eye, even the faint light disappeared without a trace.

Yang Xue, Boss Chen, and I looked at each other, and we had no idea at this time, so we had to stay where we were and wait.

After waiting for about half an hour, I still didn't see Mr. Mao come back, I looked at Yang Xue's appearance, a little shaken, and Boss Chen's face was also ugly, so I said that it looks like Mr. Mao can't come back, I think we should withdraw, right?
