By the time we got over, the man had already run to the turn of the ramp leading to the previous level. Even though I had predicted it, we had seen it more than once, but I was still shocked to see his back.

The person who opened his feet and ran up was wrapped in a long-haired shawl, wrapped in a piece of broken felt that he couldn't tell whether it was animal skin or made of plant fibers, and carried Lin Xian'er's hiking bag behind his back, and the bare feet and the bones on the calves of the two halves were all visible.

Just looking at the legs and feet is enough to make people scared, not to mention the face, maybe how terrifying! Lu Keqin and Lin Xian'er slowed down significantly. We were scared, but we knew in our hearts that we had to catch up with this person. Of course, not only because he was the murderer of Hu Xiaoming, but also because the fact that such an unknown person living in such a place is a mystery in itself.

The ramp from the upper level to the top is much steeper than the lower level, and the section is slightly slower before the turn, and the road climbs up at an angle of almost 70°. The man was very fast, and if it weren't for the limited distance on the ramp, we would have lost the man.

Using both hands and feet, Lu Dachuan was the first to run out of the well-like passage and came to the ground above. I thought that the upper layer would be like the two floors below, with caves connected to passages, and passages connected to caves, but I didn't expect that what appeared in front of me was a large platform like a square.

The man who ran up first ran diagonally towards the left wall. Lu Dachuan didn't bother to carefully look at what was on the platform, and ran forward after him. Liu Changleg and Liu Fashan did not fall behind. I was dragged by Lu Keqin, I was anxious but I couldn't run fast, so I simply slowed down and looked at the platform in front of me carefully:

The platform is oval as a whole, the entrance at both ends is narrow, the middle is wide, the dome height is more than ten meters, the upper, middle and lower three layers of caves on the right stone wall are irregularly arranged, and the caves on the left stone wall are also divided into upper, middle and lower three layers, and the arrangement is also irregular.

I looked at the holes left and right, and it dawned on me that the caves on the left and right sides were originally one, just like the one below, but now I saw the huge space in the middle of the cave that someone had dug up all the middle parts of the cave above. ――I couldn't control my excitement and thought: Oh my God! That's a lot of money!

Seeing the outline of the entire platform, I lowered my head and saw that the flat stone floor beneath my feet was densely lined with countless thin knife marks, which spread like marching ants into the distance. I thought it was a trace left by digging a cave, but when I looked closely, I realized that it was all words that I had never seen before.

Seeing the words, I was so excited that I was sweating, and I didn't care about chasing them, so I immediately squatted down and touched the ground with my hand to look carefully, but when I saw the words clearly, I was dizzy, although I am not a lover of ancient characters, but I still know a little bit about the fonts of several ancient characters in the world, and the words in front of me not only have no similarities with the Chinese oracle bone inscription and tadpole inscription, but also have no similarities with the ancient Egyptian papyrus, the Babylonian clay tablet, and the Yama script of the American Indians.

I watched it for a long time, not to say that I knew it, and I couldn't even figure out which strokes were a word, because all the strokes of the words on the ground were at equal distances, and none of the two strokes were connected together......

"How can anyone write like this? It seems that the legend that they are aliens is true! ”

Seeing that I was squatting for a long time and didn't leave, Lu Dachuan and the others ran farther and farther, Lu Keqin and Lin Xian'er were in a hurry, and dragged me to chase after me.

We ran diagonally across the square to the hill wall, where the man had already run through four holes in a row and plunged headlong into the fifth. Lu Dachuan and the others should have been afraid of danger, so they didn't dare to rush in, standing at the entrance of the cave and looking inside. We ran over and stopped beside them, and saw that the hole in front of us was unlike anything we'd ever been in. First of all, there is an ashlar wall of doors and windows about two feet inside its entrance, and although there are neither windows nor doors on it, the size and orientation of the window and door frames are clear at a glance. Then I looked into the cave from the outside, and the bottom of the cave was full of things.

We exchanged glances with each other, and the expressions on our faces were full of excitement. Maybe what's inside the cave in front of us doesn't necessarily solve the mystery in our hearts, but having something in such an empty place is enough to give us hope. What's more, a mysterious person ran into the cave.

"Let's go inside!" I couldn't wait to go into the cave and find out. Others are looking forward to it.

During the time we were at the entrance of the cave, it was quiet in the cave. Lu Dachuan shook the flashlight pillar, and saw that the person who escaped disappeared like coal particles falling into the coal pile, and finally couldn't hold his breath anymore, pulled out his scimitar, stepped through the door frame, and walked into the cave. We rushed in for fear of being left behind.

The hole is narrow in front and wide in the back, like a fallen flask. Everything we saw outside was piled on top of the ground in a wide area behind us.

As I walked up, I saw that most of the containers on the floor were like water tanks, a few of them were still covered with lids, and those that fell on the ground were wide open, and there was a layer of white substance on the inner wall of the floor; Others are small containers such as pots and jars. Although these things are placed in a mess, the surface of the wood grain of each item is glowing with black oil, as if someone is wiping it every day.

I wanted to see what was in the jar with the lid on it, so I walked up to one of them, reached out and lifted the round lid that was half a centimeter thick and sixty or seventy centimeters in diameter and had the same wooden texture glowing with black light, and I didn't lift it at once: "Good fellow, what kind of wood is this so heavy!?" ”

Lu Dachuan gently knocked on the lid twice with the back of the knife, but the wooden lid that looked like it made the sound of metal being struck. He knocked on the cylinder again, and it was also a metallic sound. However, the sound is a little dull, probably because there are things inside.

Knocking on those pots and pots again, the pots and cans were all metallic. We were completely shocked. But what shocked us even more was the opening of the large jars with lids, some of which contained water, some of which contained a viscous substance, and one of which contained a small half jar of dried plant rhizomes.

Water we naturally know. We judge the viscous substance to be an oil, but we don't know if it's animal fat or what kind of plant it's extracted from. Roasted dried rhizomes, we don't recognize what kind of plant they are.

We are not archaeologists and are not in a position to do further research on these things, but to simply discuss what they might be.

Lu Dachuan looked at the water in the tank, grabbed a handful of plant rhizomes and put them under his nose and sniffed them, saying: "The water in the tank is crystal clear, and the rhizomes of plants have not deteriorated. ”

Just now, we were still discussing the truth about the materials of these containers and the contents inside, when suddenly Lu Dachuan turned the topic to the identity of the person who killed Hu Xiaoming and stole our food, which surprised us.

I said, "Impossible, right?" The appearance and clothing of the group at the foot of the mountain are so well preserved, they look like people from the sixties and seventies, even if someone hadn't died at that time, there was food and water here and they wouldn't have survived now. ”

The others didn't speak, but they had obvious expressions of disbelief on their faces.

Lu Dachuan looked at me: "Are you saying that it is impossible in time, or is it impossible to survive for a long time in this environment?" ”

"I don't think it's possible."

Lu Dachuan said firmly: "I think it's completely possible. First of all, there is nothing to doubt about the time, I remember Daddy Boba said that if his father hadn't replaced him, he would have been a member of the expedition, which means that it would not be a problem for the survivors to live to the present day if they were the same age as Daddy Boba; Speaking of the environment, this is the place where the ancestors of the big-headed villain lived, and since they can live here, why can't we, the later ones? ”

I listened to Lu Dachuan's analysis, but I still felt that it was impossible, so I thought about it for a while and said: "I guessed it in terms of age, you are right, but I still can't agree with your speculation, this is where they have lived, but living in a group and living alone are completely different things, not to mention that in such a dark place, it is crazy to let a person not deal with people for a long time outside." And the fact that they choose to live here doesn't mean they won't go out for the rest of their lives......"

"What if that person has a nervous problem?" Lu Dachuan interrupted me.

"Killed someone, and robbed us of food, you say he's a madman?"

Lu Dachuan nodded: "If he is mentally normal and has lived in this kind of place for a long time, what will happen if he sees someone coming?" I think the normal reaction should be to be surprised, like seeing a loved one. But he kills and robs food. Lu Dachuan deliberately paused when he said the word "food", emphasizing that he only grabbed food, not other property, "This is the first place where I think there is something wrong with his nerves, and the second is the place where he fled to after we found out." Lu Dachuan pointed to the things in the metal vat in front of him, "Judging from these things, this is where he usually lives, there are caves extending in all directions outside, he runs so fast, he can find a place to hide, but he didn't go anywhere, and took us straight to his residence, isn't it too abnormal?" ”

I was somewhat convinced: "Maybe you're right, but what about others?" ”

Lu Dachuan pointed to the depths of the cave and said, "There is nowhere to go here, so I can only hide in that cave." ”

I looked at the place where Lu Dachuan pointed and saw that there was a hole in the wall of the cave inside.

"How can you be sure that's where he lives? If it is the same passage to other caves as below, we have been delayed here for so long, he won't run early! ”

"Isn't it, just go in and see. If everything doesn't go according to my expectations, we'll have a great harvest in it. Lu Dachuan ended our discussion and walked towards the small hole in the front wall of the cave hall that he had seen for a long time.

"What's the big catch?" I muttered to myself, but didn't ask.

We will be suspicious and follow Lu Dachuan. Suddenly, I felt uneasy again. After entering this cave and seeing the well-preserved water and unnamed food, I made a guess in my heart that it was similar to Lu Dachuan, the difference was that Lu Dachuan thought of the members of the scientific expedition team, and I thought of my father. Before, Lin Xian'er said that if that person was my father, he should come out to recognize him, instead of killing people and stealing things, so I dispelled this idea, but Lu Dachuan deduced that that person might have become a madman, and I thought it might be my father.

The back wall of the cave wasn't far from where the stuff was stacked, and in less than a minute we were there. Lu Dachuan stopped at the entrance of the cave, made sure that there was no danger inside, and walked in. We followed behind, and none of us looked back at the cave.

It is said that none of us are sloppy people, especially Lu Dachuan and Liu Fashan, but after discovering that person, we seemed to be fascinated by ghosts, and completely left the other two groups behind.

Originally, we were going to be the yellow finch behind the praying mantis, but we didn't expect that because of this serious negligence, we became someone else's turtle in the urn.
