Just in case, we held the QX16 rifle in our hands and stuck the flashlight in the position of the handguard of the gun bodyguard, so that we didn't have to hold it in our hands, and we didn't have to wait for emergencies.

The passage is not very wide, at most about two meters wide, I walked in front, observing every move around me, the surroundings were surprisingly quiet, except for the sound of me and Huayu's breathing and footsteps, I could no longer hear any sound.

Not long after we walked, Hua Yu said to me in some surprise, "Do you feel like we are going downhill?" ”

I also felt it, I always thought it was because we tied the gun to the handguard of the rifle, and the body of the gun was weighted off the illusion of our moving footsteps, but Hua Yu's words confirmed my suspicions.

"Since it's a downhill road, it means that the smell of corpses we smelled before is not an illusion." I crouched down and looked at the passage ahead, drew my dagger, and then prepared to split a piece of the stone wall next to me to test the momentum.

My hand just raised and didn't hit it yet, when Hua Yu behind me suddenly said, "Wait a minute." ”

I turned my head to look at Hua Yu in surprise, only to see that Hua Yu's eyes were not on the ground of this passage at the moment, but looked at the situation around the wall with an extremely shocked expression.

"Any questions?"

Hua Yu pointed to the wall in front of me and said, "Look at the wall. ”

I hurriedly turned my head to look in the direction that Hua Yu said, and under the illumination of the flashlight, I clearly saw that a large mural appeared on the wall on the right.

Judging from the figures on the murals, it should be some of the older Western history of the carvings, and the murals are carved with dense pictures of ancient times, and under the illumination of the flashlight, the end of the mural cannot be seen at all.

I took another picture of the mural on the left, and there was nothing on it, still the same as when we entered the passageway.

The situation at this moment made my scalp a little numb, and I said to Huayu in a deep voice: "No, why didn't we see these murals when we just came in, why did the murals appear as soon as I squatted down." ”

"I don't know, I'm wondering, but looking at the murals on this, it seems that the old and new ones are different, some of the murals have been carved very early, and even the colorful pictures on them are different."

Hua Yu said that he was about to touch the murals on the wall with his hands, but I hurriedly grabbed her and said, "Don't touch them, these murals are very weird, be careful." ”

The murals on the walls are artificially carved, but judging from the shape of the people on the murals, they are all the same size as normal people.

Some of the murals depict people working in the fields, some at home, and some seemingly playing.

The carvings on the walls can be said to be lifelike, and with the colorful drawings, we have a sense of immersion.

We kept going inside along the murals, and the more we went inside, the more hairy my hearts and I became, because the time of these colorful carving strokes was getting newer and newer, and Hua Yu deduced that these murals were probably half a year ago.

I looked at the murals in front of me and said suspiciously: "Why did Samochi carve so many murals here, what is his purpose, could it be that he just likes it?" ”

Hua Yu said, "Maybe, let's continue to walk inside." ”

The murals on the walls can be said to be different from each one, and from beginning to end it seems that these murals are all about the evolution of human beings.

When the mural reached a corner, it was gone, so I raised my flashlight and took a picture behind the corner, and found that the road behind me was a downward staircase, but there was still no end in sight.

The murals on the wall are gone, and Huayu and I don't pay attention to the murals anymore, and we turn on the flashlights and walk down.

After walking for more than ten minutes, we came to the end.

After walking the last step of the stairs, there is an empty underground building in front of me, there is nothing in the building, it is a hole in the ground that has been dug artificially, and judging from the time of excavation, it has been some years.

The empty cavern was hemispherical, about fifty meters in diameter, and there were a few things placed right in front of us.

I hurried to the front to look, and found that all the tools that were piled up here were some of the tools used to dig caves, and the rest was gone.

Hua Yu shines in the cave with a flashlight, trying to find some clues from the cave wall, but there are other things in the cave except these tools used to dig Shandong.

"Looks like there's nothing left here, or let's go back the way we came." I said with some arrogance.

Hua Yu was different from what I thought, and said to me while looking for it, "Don't you think something is missing?" ”

"What's missing?" I looked at the empty cave, I really couldn't remember what was missing, and just when I was about to say nothing, a bad premonition came to my mind: "Why are there no corpses here?" ”

I hurriedly took off my gas mask, raised my nose and sniffed it, although I could still smell the smell of corpses, but the smell here was already very faint, and if I didn't pay attention, I wouldn't be able to smell it at all.

Hua Yu said: "Yes, when we first entered the passage, the smell seemed to be close at hand, but now it is gone, we have not found any other way along the way, but the smell of corpses is gone, which is really unacceptable." ”

My heart is like ten thousand strands, and I really can't find any reason to convince myself, and the actual situation is in front of us.

I said to Hua Yu: "Judging from the smell of corpses, the distance is very far from us, but when we first came in, there was only this way, and when I came out, there was nothing left when I came out of the row of murals that suddenly appeared. ”

"A mural, it's a mural." Hua Yu seemed to think of something as soon as I was reminded of it, and hurriedly beckoned me to go back.

I also thought that something was wrong, and since the smell of corpses came from the direction from which I came, it must still be there.

However, we did not find a single corpse, which means that the smell must have come from the people on the mural.

But why does the carved human painting smell of corpses, this is completely unreasonable.

The doubts in my heart have risen to a new level, but the passage we have entered has been unable to tell the doubts, and no one can say how much is behind it.

Hua Yu and I were in a hurry to go back, so we also quickened our pace, trying to confirm whether the smell of those corpses was coming from the stone man murals on the wall.

But in the hurry, I didn't pay attention to my feet, I stumbled and fell to the ground, Huayu turned his head and saw me fall to the ground, and hurriedly turned back to help me.

I wondered in my heart, when the road was so smooth, something would trip over me, could it be that we didn't pay attention when we came in?

But when I think about it, I don't think it's right, Hua Yu walked in front of me, how could she be fine, but I tripped up.

My knee hurt even more, and if it weren't for the loose ground on the ground, I'm afraid my leg would have been ruined.

The rain lifted me up from the ground, and as soon as I stood up, I felt that my ankle was wrong, as if someone was pulling my ankle, looking down, and looking down at the pillar of light of the flashlight, the cold sweat behind me was pouring out layer by layer, because it was a white Sensen's human hand that grabbed me at this moment.
