Hurried footsteps sounded behind him.

At first, we thought it was a shadow, but when we looked back, we realized that it was not a shadow, but a person who made the three of us feel short of breath at the same time.

It turned out to be Mr. Peng, who had died in Yinyu Village, which we had seen before.

At this moment. Suddenly, when Mr. Peng appeared here, the three of us retreated one after another. Feng Tiansong and I protected Xiao Qicai behind us, and at the same time put on a fighting state, and if Mr. Peng had the intention of attacking us, we would strike first without waiting for him to get close.

At this time, I carefully observed Mr. Peng's every move. I saw that he walked quite normally, not like the tip of his nose and the tip of my nose when the corpse had changed before, but it was just an unconscious, breathing walking corpse.

What was happening in front of me made my head a little unconscious, and for a while I couldn't figure out what Mr. Peng was. It wasn't until he came to a stop about a meter away from us that I was still a little bit incredible.

At this time, Mr. Peng spoke like an ordinary person. As soon as he spoke, we were all taken aback.

"Hello, three young men!" Mr. Peng said.

Xiao Qicai stared at this person, and said with an expression of disbelief, "You...... Aren't you already dead? ”

Mr. Peng was silent for a long time, and suddenly said, "When you enter the village, you must die, and the dead can run rampant!" I've reminded you many times, and it seems that you don't understand the true meaning of this statement! ”

As soon as this statement came out, we were all a little surprised. I didn't expect this weird ballad to be sung by Mr. Peng, but at that time, in such a strange environment, everyone felt extremely depressed, who can really understand the true meaning of this sentence?

But in fact, Mr. Peng didn't answer Xiao Qicai's question, so she quickly asked again. "Why can you die and be resurrected?" "Mugou begging.

Mr. Peng said, "This is not the place to speak, please come with me." ”

We all stood and didn't move.

Mr. Peng made a gesture and said, "Please believe me." And we don't have much time, so they might be here when. We've got to hurry, and then, I'm going to get you out!" ”

This sentence makes us confused. First of all, they? Who are they? What does it mean that there is not much time? For a while, we couldn't figure out what Mr. Peng really wanted to say, so we still stood and didn't move.

Mr. Peng still doesn't trust him very much when he sees us. So he took a deep breath, looked at Feng Tiansong, and said, "Twenty years ago, you came here. Remember me? If you think about it, at that time, you were still a child. ”

Feng Tiansong looked at Mr. Peng in front of him, showing a puzzled expression.

Mr. Peng looked at Feng Tiansong and said in a soft tone, "At that time." The rainy village in front of us was not a rainy village yet, because the two of us were the first people to arrive here at that time. Later, you were taken to a cave by the second group of people who arrived here, and some experiments were done on your body, remember? Those people were originally members of Unit 731. ”

Feng Tiansong's body shook involuntarily and fell into memories. For a long time, Feng Tiansong seemed to remember something. With a somewhat frightened expression, he said, "Those people...... Where did the people who took me away go? ”

"It's too complicated, and this is not the place to talk, so you have to trust me, we really don't have much time. If they come, you won't be able to go back. ”

"Then let's kill you first!" Suddenly, another voice behind me interjected.

We immediately looked in the direction of the sound, only to see that the shadow did not know when it started, and it also came over. Maybe she was impatient to wait over there, so she came over to see what was going on.

At this time, as the shadow spoke, the peculiar scimitar in her hand had already shone out, and the whole person exuded a solemn murderous aura from the inside out!

But Mr. Peng didn't mean to be scared at all, he didn't even move the eyebrows on his face, and he didn't look back, "It's useless to kill me." Even if you have a way to get out of here, these two friends of yours ......" Speaking of this, he pointed to me and Feng Tiansong, and said, "They are already very human. If you don't mind, you can kill me and find a way to get out of here, but their lifespan will definitely be affected. ”

"I don't have any friends!" The shadow said lightly. Although she said this, the knife in her hand did not take any action immediately. Seeing this, Xiao Qicai hurriedly walked in front of the shadow, blocked the shadow's sight with her body, looked at Mr. Peng, and said, "You want to take us there?" Is there any way you can save these two people? ”

Mr. Peng shook his head slowly and said, "No one can save them." The only one who can save them is themselves. But I can help you. The premise must be based on complete trust in me. ”

Xiao Qicai hesitated, and I winked at her. With a shadow by our side, if Mr. Peng really has malicious intentions towards us, we should be safe. And if Mr. Peng really met Feng Tiansong 20 years ago, I think there must be some origin in this that we don't know. In order to find out the secret here, I think I should trust Mr. Peng for the time being.

So I nodded and said, "I trust you." Hurry up and take us there! ”

"Good!"

Mr. Peng nodded, didn't look at the shadow, turned around and left.

I immediately strode to follow, and Xiao Qicai pulled Feng Tiansong to follow behind. Looking back, the shadow stood there and hesitated for a long time, and finally followed unhurriedly. I'm sure Shadow must have been curious about this place too, and if the order she gave her above was to protect us, she must follow it now.

After a while, Mr. Peng took us through the "tropical" area to the cold zone, and he took us all the way in one direction (I'm sorry, at this time, in this mysterious place, I can't tell the difference between southeast and northwest, so I can only follow Mr. Peng all the time)

Eventually, he passed through the narrow stone pinnacle layer by layer, and kept moving forward.

At that time, the path was very strange, the further you went inside, the narrower it became, and in the end there was only a narrow passage left in some stone crevices, and you had to crawl to get through. It feels like walking through a crack in a stone, the space is very aggrieved, and at the same time, I feel like I have become an insect and want to drill into the stone.

Fortunately, we moved hard in the stone for a while, I don't know how many stone crevices we walked through, and finally our vision became wider again, and the temperature changes along the way, high and low, although not as hot to the extreme and cold to the limit as before, but also extremely uncomfortable, the skin and pores seem to be blocked, breathing is also difficult, and the whole body is uncomfortable.

At this time, I had the feeling that we had been walking "down", and that feeling made me inexplicably afraid. I always feel that following Mr. Peng will go directly to the lowest and lowest place in the world, and I don't know why I feel this way, but the feeling of moving down all the time is very unforgettable.

Finally, I don't know how long later, Mr. Peng led us to a dark and empty area. It didn't take long for countless rays of light to shoot overhead. It looks like a cave with light in all directions. However, the air here is thinner than before, and as soon as we arrived here, we immediately felt a sense of extreme depression, and we were a little afraid to speak out loud, which was very difficult.

Mr. Peng stopped, and everything around him suddenly became extremely quiet, as if we had come to a place of death, where no living thing could survive.

At this time, Mr. Peng whispered in a voice that we could just hear clearly, "This is the middle ground, the only safe place I can find." ”

In the darkness, I couldn't contain my curiosity and asked, "What the hell is this place?" ”

I thought Mr. Peng would say, "This is the mysterious fourth dimension!" Or "another dimension".

However, even if I thought of many unusual answers, I could not have imagined that Mr. Peng would say, "This is the center of the earth, the middle ground between the earth's inner core and the outer core!" ”

After saying this, everyone was greatly surprised!

Xiao Qicai's emotions were a little irrepressible and excited, "How can it be the center of the earth?" As far as I know, the deepest part of the earth's outer core alone will reach 5,000 kilometers, and if it is the middle of the earth's core, it should be about 5,100 kilometers deep. ”

Mr. Peng said, "Yes, the interior of the earth starts from the surface of Gutenberg and goes all the way to the center of the earth, which is called the core. The Earth's core accounts for 31.5% of the Earth's mass and 16.2% of its volume. To put it simply, the Earth's core is larger than Mars in the solar system. Since the Earth's core is in the deepest part of the Earth, it is subjected to much greater pressure than the crust and mantle parts. In the field core, the pressure has reached 1.36 million atmospheres, and in the core it has increased to 3.6 million atmospheres. ”

Speaking of this, Mr. Peng paused for a moment and said, "It is difficult for people to imagine such a great pressure on the surface of the earth. We have previously experimented with the hardest diamonds to become as soft as butter at a pressure of 1,770 tonnes per square centimeter. But...... Since I came here in that mysterious area of Lop Nur, all my research and all my scientific knowledge have been turned upside down! ”

Mr. Peng said this, and did not go on. I think we need to understand and digest it for a while before we can understand what Xiao Qicai and Mr. Peng mean.

In fact, if we describe it in a very simple way, it means that there should not be any humans or other creatures here, because the pressure and temperature here will cause all living things to be crushed into a "cake" shape, or simply destroyed. However, it is still the same old saying, what is obviously impossible to happen, but now it is happening vividly in front of us.

I believe that Mr. Peng must have a deeper understanding of the research here, so at this time, I forced myself to suppress the shock in my heart, and waited for Mr. Peng to continue to speak.
