I could see that the rest of the people were scared and ran back, while Zhao Tiesuo and I stood still and didn't move.

Sister Hua turned around and shouted to the two of us while running: "You two run quickly, what are you doing standing there stupidly?" Then he said to Fat Brother, Yan Qiu and Lu Shan: "Look at your feet, don't fall into the cage." ”

I'm not afraid, I'm frightened, when I came face to face with this big bat just now, I had already planted a shadow in my heart, and now when I see it, I'm so frightened that I can't walk, and my two legs don't obey the call at all, as if they have grown roots and are fixed on the ground. I wanted to ask for help from others, but I couldn't open my mouth and couldn't speak.

Zhao Tiesuo stood beside me, picked up the pistol, and first two gunshots rang out, hitting the bat's heart, and then another, hitting the bat's head. Then there was the sound of the magazine falling to the ground, and then he casually replaced it with a new one, holding the gun and not continuing to shoot.

The big bat was still in the shape of a large unfolding, but it seemed to be frozen, and it didn't move again. After a while, I heard a shrill sound like ringing in my ears, which shook my head with a pain. The chirp ended, and the bat fell straight backwards.

I also fell to the ground with it, and sat on the ground with my ass, sweating all over my body.

Zhao Tiesuo ran to the bat in a few steps and kicked it twice, but the bat was motionless and dead.

The fat brother shouted: "Good marksmanship." ”

The four people who had run away walked back again.

Zhao Tiesuo smiled and said, "What good marksmanship?" It's so close, and it's so big, anyone who can use a gun should be able to hit it, but I don't know if the heart of this thing also grows there, and after I fired two shots, I remembered that I had another shot in the head. ”

Lu Shan and Yan Qiu came to study me, who had frozen, and the two of them alternately waved their hands in front of me.

I came back to my senses, stood up and didn't say a word, just patted the dirt on my buttocks, and the horrible picture just now is still playing back in my brain.

They all gathered around the bat's corpse and kicked the bat with their feet, still studying how the bat could grow so big.

I deliberately bypassed the bat, not wanting to look at it again, and walked down the slope inside the tunnel mouth.

It is not a tunnel inside, just a downward slope, the two sides are very wide and you can't see the edge, the top of the head is also very high, with a flashlight, you can see clearly that it is a soil top, and there is no trace of artificial carving, hundreds of meters long slope is the land, loess mixed with the soil of sand.

Descending to the bottom of the slope, the roof of the cave is no longer visible, probably because we are going down, and the distance from the top of the cave has been shortened.

In this huge space, we feel a little lost, we don't know which direction to go, we just blindly move forward. I had a vague feeling that this was not a cave dug out by hand, but a large hollow cave formed naturally.

With no walls around, we feel like we are on the Gobi Desert at night, except that there are no stars or moon at night.

Yan Qiu confirmed my guess, she said: "This place is not like it is artificially excavated, but like a natural hole, such a big hole, I don't know how it was formed?" ”

What I think in my heart is not the formation of the cave, but why the ancients connected the many mechanisms to this cave, what kind of secrets are hidden here, or what kind of dangers are hidden? If the big bat is just the beginning, then what we will encounter later, with the remaining two shuttle bullets of Zhao Tielock, can it be settled?

After walking a short distance, the fat brother pointed to something on the ground and said, "Look, what is this?" ”

We walked a few steps closely, and found that in front of the fat brother's feet, there seemed to be something buried in the soil, something like a shell, I used my hand to remove the soil next to it, and picked it up, it was a conch.

The conch is spiral-shaped, with white patterns distributed on the reddish-brown carapace, which spread backwards along the direction of the conch's growth.

Lu Shan snatched it up, looked left and right, and then stumbled and said, "This, this, this is, it's a nautilus." ”

"What happened to Nautilus?" I asked disdainfully, expressing my displeasure at her rude behavior of snatching something from my hand just now.

Lu Shan didn't care about my tone, but continued: "Nautilus, a living fossil, endangered, a first-class protected animal. ”

We all don't care, it's a protected animal now, not necessarily a protected animal in ancient times, and the possibility of a nautilus burial object is not impossible.

A few steps further, I felt that my thinking was a stern mistake, because what appeared in front of us was a large piece of nautilus remains, mixed with other kinds of shells, fish bones, and insect beetles, half-hidden by the sand. What is the reason for the emergence of a large number of marine organisms? None of us are conclusive.

The fat brother said in surprise: "Cao Cao built an aquarium here? ”

Zhao Tiesuo shook his head and said to the fat brother: "How could there be an aquarium in ancient times? ”

The fat brother said: "It's a place to raise fish, it's not called an aquarium, I don't know what it should be called." ”

Lu Shan said: "These animals should live at the bottom of the sea, about 100 meters deep, if they are brought here alive, then this hole will be big." ”

I still think it's a scattered funeral item, and we have to walk forward to see what the situation is.

Going further, several of us were completely stupid, and we could no longer speak, because as far as our eyes could see, there was an extremely shocking picture, not horror, not horror, but real shock.

Right in front of us, there were scattered large skeletons, which were bent like ivory, neatly arranged, standing symmetrically on the ground in pairs, and there were seven or eight groups that could be seen.

The fat guy shouted, "Dinosaurs." And he ran over.

When we got closer and looked closer, there was a long vertebrae in the middle of the big bones standing, and there was a huge skull in front of it, which really looked like a large dinosaur, and it remained the same as when it was dead, with different shapes, not like it had been placed by someone.

The others were also curious, and Sister Hua said excitedly: "Huo, we have come to the dinosaur ruins, right?" Jurassic Park? ”

As soon as she said this, I trembled a little, a bat is enough, if there is a Tyrannosaurus rex that is not dead, who can deal with it?

Lu Shan said: "This is not a dinosaur skeleton, no matter how you don't understand it, you should know that dinosaurs have legs, right?" ”

As soon as I heard this, it made sense, that there were no limbs around these big bones.

"Is this a fish?" Yan Qiu asked Lu Shan.

Lu Shan nodded and said, "Yes, this is a whale, a big whale bone." ”

I don't think it's strange to see dinosaur bones here, if this cave is a place of refuge for dinosaurs, and there are living dinosaurs that continue to survive in the dark, but to say that this is a whale bone is a bit sadistic. Seeing that there is a school of whales, how much sea water does it have to be here for the whales to survive here?

Is there someone who keeps whales here, or is this the ocean in the first place? Lu Shan didn't know it at all.

I took a few more steps forward, looking for other clues, trying my best to find evidence, trying to overturn Lu Shan's speculation, but if I went further, I couldn't convince myself anymore, there were patches of strange rocks in front of me, the strange stones had many holes, shaped like cacti in the desert, no need for Lu Shan to say, I knew that it was dry dead coral.

As the number of shell remains on the ground gradually increased, I seemed to see what this place looked like before it dried up, and what appeared in front of my eyes was clearly a thriving underwater scene. I can't believe my thinking, I always feel that something is wrong, the sea is not fresh water, the underground river is reasonable, if there is an underground sea here, then the land above, our entire Central Plains, is not in the ocean?

I immediately thought of Yan Qiu, so I went to consult Yan Qiu: "Is there a record of our continent under the sea in history?" ”

Yan Qiu explained: "In the early days of the formation of the earth, it is very possible to say that we are here for the ocean, but since the historical records of the Chinese civilization, and even the unwritten era when there are legends, there will definitely be no ocean here. ”

As soon as she said this, I came to a serious conclusion, which is that the people who had instructed the builders of this place had brought a sea for their burial. Thinking of this, the muscles in my face began to twitch constantly.
