"Okay, fortunately everything is fine. Let's go back quickly. We have to find another place to get fresh water from now on." I said.

After this scare, no one dared to stay any longer and hurried back to the camp, not daring to speak along the way. They also got closer to me, fearing that they would be left behind. Therefore, the distance between them and me had already exceeded the safe distance, which seemed very ambiguous. After all, they were so close that it was not much different from the intimate relationship between lovers.

I could hear their anxious breathing and even the gulping sound of them swallowing.

When we got back to the temporary camp, everyone looked very terrified. Seeing them like this, I could only arrange them in shifts of two to keep watch.

The Song sisters were a little surprised. Yunwen and I were better, so they went to bed first, and the two of us were responsible for guarding the campfire.

There are more mosquitoes in summer nights, especially in the wild wasteland with camphor trees in the mountains. Without mosquito coils, we will be bitten all over. We can only endure it as much as possible. Fortunately, the night wind is cool, and the occasional sea breeze while we are on guard is a bit of enjoyment.

I was already feeling hot and irritable and couldn't sleep, and I didn't feel sleepy at all when I was on guard. I was thinking about these strange things in my mind, feeling anxious and uneasy. I always felt that we were like a small fish in a calm pond, and we might be devoured by piranhas at any time.

"You are thinking about the piranha, right? We also saw the churning water in the underground river in the cave, but the piranha did not attack us. But it suddenly appeared tonight. You are confused about this, right?" Yunwen suddenly asked.

I nodded immediately. I was worried that no one would share these things with me. Thinking about them alone always felt very tiring. And I am an impatient person. If I don't think of the answer at the first time when something happens, I will feel uncomfortable.

"Yeah, it's so weird. They either bite people when they see them, or just hide in the water. I don't know why they behaved so strangely tonight. This is not in line with the characteristics of this creature. After all, they are more impatient than me." I said.

"Actually, I know something, but I don't know if it's right or not. It was mentioned in the burnt pages. The general meaning is that the piranhas in the worm hole don't like to eat people. They are used to a certain kind of food, so they don't attack people. Their interest in people has decreased, and they would like to eat things in the cave more. As for the piranhas in the pool just now, they like to eat people, but it should be you who stirred up the water surface and caused large waves in the water, which attracted them." Yunwen said.

This possibility is indeed greater. Moths and piranhas have already formed a unique food chain. The eggs laid by moths may fall into the water and be eaten, and the larvae may also fall into the water and be chewed up in an instant. Moths generally cannot survive certain low temperatures and will die before wintering. It is also possible that they fall into the water in the cave and are eaten.

Therefore, the piranhas there are accustomed to eating this kind of food. Once the food chain is formed for a long time, it will slightly affect the natural selection of organisms. It is like leaving a person to survive in the wild from infancy. In the end, it will be difficult for him to return to the human world, integrate into society and start a new life.

The moths and the underground river piranhas have undergone subtle changes over generations, resulting in different habits, while the piranhas in the pond still retain their original habits and will attack and eat people, but they will also express their irritability, excitement, and presence by churning up the water in the pond.

"It seems that the people in the Milong Camp are more powerful. They understood the situation immediately. This makes me curious about what else is said in the remaining pages. Also, did Li Mufeng escape with his brothers later? Where did they escape to?" I asked.

"There is no record of this part. The record on the last page is that Lord Li Zihu said: 'If you want to live, you must obtain the supreme treasure, and then you can live. If you cannot die, you can be sent back to your hometown in glory.'" Yunwen said.

"What do you mean?" I asked a little embarrassedly.

"That is to say, if you want to survive and don't want to die, you have to go find the supreme treasure. Only then can you not only survive, but also return with success and fame." Yunwen said.

After that, we talked about some other things. I accidentally let out something about the hallucinations I had, and talked about some of the things that happened in the hallucinations, which made Yunwen laugh continuously. I asked her why she was laughing, and she said that it was impossible for her to kiss me on the plane during her working hours, and she would not even call me by name or ask me to follow her, as these were not allowed during her work.

If she didn't want to be scolded by the captain, she would never do that. Then she immediately changed the subject and said, "But if you want to kiss me here, I will agree."

As she spoke, she couldn't help but lower her head. Her pretty face looked red, perhaps because it was roasted by the bonfire.

I struggled with it for a while and really wanted to suggest continuing the kissing scene in the dream, but when I was about to say it, I saw that she was a little dozed off, so I took my words back and said, "I just can't sleep, you go to sleep first, I'll watch over you."

She felt a little embarrassed and said, "How about that, let's just follow the old rules. Call me when you're sleepy."

I nodded.

She once again lay on my legs skillfully, hugged my waist without any hesitation, put her face on my abdomen, and said before going to sleep: "Zhou Bo, I think what Senior Li Zihu said is right. Maybe the supreme treasure is the key to solving our survival problem. Whether it is the mysterious beast you mentioned or the piranha, they may be related to it. As the saying goes, no matter how things change, they still have their roots. If you understand the roots, you can also overcome all changes, right? You can consider it."

Not long after she finished talking, she fell asleep, and I thought about it. The piranhas that were twice as big as usual, the giant moth known as the white devil, Bigfoot, the evil leopard, the poisonous eagle, and the unknown giant bird in the sky, all these abnormalities seemed unrelated, but there seemed to be some correlation. Maybe Yunwen was right.

One move can break all methods, but you should also consider what Senior Li said: "If you want to survive, you must obtain the supreme treasure."

After that, I stayed up until three o'clock in the morning, woke up the Song sisters, and then took Yunwen to sleep in the tent built with wooden sticks and animal skins. She rested her head on my chest, leaned on my arms, and stuck close to me, feeling like a couple who had been together for a long time.

There were fewer mosquitoes in the makeshift tent, and I fell asleep soon.

The next day, we got up as usual, just like yesterday. We asked Bai Lu to stay at home to watch the bonfire and do some logistics. After Yunwen and I finished our work, we came back to find a new residence together. The Song sisters also nodded in agreement.

Yunwen's little face rested on my arm last night, and it's still a little numb. I woke up earlier than her in the morning and stole a few glances at her, so my neck also feels a little uncomfortable, but mentally I'm quite happy with this discomfort.

I walked down the iron steps, groped for the pull gate on the wall, and pulled it down. I expected the iron gate to open automatically, but I found that the door was stuck and could not be opened no matter what. I kicked it a few times in a hurry, but it didn't work. I thought about finding another way out, but I found that I had to jump five or six meters to get from the top of the mountain to the mountain road along the city wall.

"It seems that there may be a problem with the circuit. I'll go find the cause. You wait here." I said to Yunwen.

She nodded and said, "I'll do as you say."

The power wires of the switch were hanging on the right side of the mountain top and extended forward. I walked up the iron steps back to the top of the mountain and followed the direction of the power wires all the way to the right, wondering if the wires had been broken because they had not been used for too long, or if there was some problem with the power supply.

I walked along the rotten wire for a long distance, and suddenly I saw a fox gnawing on the wire. I hurried over to stop it, but it was aware of me and just looked at me, then walked away leisurely and ran into the bushes.

I walked over and was about to fix the wires, but was immediately stunned by the scene in front of me. There was a crashed helicopter in front of me, and that helicopter seemed to be transporting some supplies. Next to it, there were cans all over the ground. Behind the crash, there was an underground entrance, and I could vaguely see the same iron steps as outside.
