I dragged Cui Hao to move through the bookshelf, he walked in front of me to help me find my way, and I was in charge of drawing the map.

"Keep an eye on your surroundings and listen carefully, if the gears turn again, these shelves will most likely move again."

I thought about it, but I couldn't stop it.

We can only continue to explore and draw a road map according to the current layout for the time being.

Cui Hao nodded at me and walked in front of me to carefully observe the situation around me.

The bats above us all shrank back and hung from the roof. The two of us kept our voices as low as we could, so as not to alarm the again.

I watched the bottom of the bookshelf, looking for the entrance. When the mechanism was activated, the bookshelves with increased height at the bottom had already been mixed with the bookshelves and disappeared.

I reached out and tapped at the bottom of the shelf, trying to find the one with a hollowed-out underneath and a secret passage.

It's a pity that most of these bookshelves have been heightened, and the patterns on the supports below are all carved consistently, so there is no way to lock on to the target at a glance.

I can only tap my hand and make a sound when I pass by these bookshelves to determine if it is hollow.

Every time I made a sound, I stared at the black bats above me in horror, for fear that they would fall from the sky and attack me and Cui Hao.

Luckily, the whole process went relatively smoothly, and the bats didn't attack us again, as long as I hit the bookshelves a little more slowly and at longer intervals, I wouldn't alarm these guys.

Cui Hao and I walked through the entire underground bookshelf again, only to find that the entrance was gone.

It must have been a bookshelf that was moving to block the entrance and seal the place. It seems that wanting to go back the way you came has become a luxury.

"What to do? I can't even find the entrance, so we won't be trapped here, right? ”

Cui Hao was more anxious than me, he kept picking at the walls around him, but whenever there was a bookshelf close to the wall, he would try to move the bookshelf to see if he could find the entrance blocked by the bookshelf.

I shook my head and stopped Cui Hao.

"I don't know where we touched the mechanism, and as a result, the two of us were locked here, but we still have a chance to live. It's the hollow bookshelf, and if we find it, maybe we'll find a way back. ”

I took a breath and pointed around.

"Fortunately, there is still air here, we don't have to worry about being suffocated here, but the most important thing is that we must go down as soon as possible, otherwise we will have to be trapped here sooner or later."

Cui Hao nodded and looked back at me blankly.

"Haven't we all gone through it all? Every bookshelf was knocked, and the hollow one seemed to be gone. ”

I shook my head and followed the route drawn on the paper, going back the way I had come.

"No, when we first started drawing, there were still a few bookshelves that we didn't find, and I think it should be one of those ones. Let's go back as soon as possible and find a way out of this hellish place. ”

I always felt like the bats were moving above my head, as if they were about to pounce on me.

And they're becoming more and more active, and they're becoming more and more responsive to the sounds we make.

Even Cui Hao, who has a big heart, already feels that something is wrong.

"How do I think these bats above are moving more and more, and even if we make a small sound, they will shake their wings."

I nodded, my heart became more and more anxious, and I dragged Cui Hao to speed up.

I had the same hunch, and I always felt that if we didn't find an exit, these paralyzed bats might actually attack the two of us.

Depending on their intensity, if they attack us, the two of us will inevitably be gnawed into white bones.

I sped up and didn't care about the sound, and quickly rushed to the bookshelf where we came, dragging Cui Hao to the side of the bookshelf.

"Quick, knock, see which one is empty."

I looked up and saw that the bats had already opened their eyes, and the dense scarlet eyes locked on the two of us.

They slowly stretched their wings, as if they had not yet woken up from their sleep, but I was covered in sweat from such a huge amount of coercion.

Cui Hao hoarsely voiced, quickly grabbed a row of bookshelves, and banged.

I'm on the other side, looking for the entrance.

"Click!"

Just as I knocked on the last shelf, I heard a familiar voice again.

"Here, Cui Hao, come here."

I immediately locked on to the target and quickly called Cui Hao from another row of bookshelves.

Cui Hao turned to look at me, his face was extremely pale, he made a shushing gesture at me, and stretched out his finger to the top of our heads.

Look up.

The bats had already come down from overhead, hovering low in the air, about to fly over us.

I immediately stopped what I was doing and avoided making any noise.

I suppressed my anxiety and carefully observed the bookshelf in front of me, searching for the location of the entrance.

I saw an inkstone at the top of the bookshelf, hidden behind a few books, extremely inconspicuous.

If I hadn't been observing, I wouldn't have seen anything hidden here.

There was no such configuration on the other shelves, so I pulled out the books and reached out to retrieve the inkstone.

It's just that when I didn't want to do it, I found that this inkstone was inlaid on it, and there was no way to take it down directly.

But when I tried to turn the inkstone, it was able to move freely.

I immediately realized that this might be the switch, and I quickly turned the inkstone, and immediately the sound of gears turning could be heard under the bookshelf.

In the next second, an entrance to a black hole nearly half a meter high and a meter wide opened under the bookshelf.

By this time, the bats overhead had gotten rid of their drunken state, and had apparently targeted me and the fat man.

"Fatty, come on."

I let out a low growl, quickly turned and slipped into the passage.

Cui Hao followed closely behind me and slipped into the secret passage of the bookshelf.

The two of us didn't dare to stop at all, and we kept crawling forward in the secret passage.

The moment the two of us entered it, there was an overwhelming sound of wings vibrating outside, and the bats all fell from the sky and flew down in circles towards the ground.

Luckily, the two of us were quick to dodge, and before they could get close to the ground, the two of us had already gotten into the bookshelf and successfully entered the dark tunnel.

I looked back, and the bats were hovering and flying in front of the tunnel, and they didn't move, as if they were very afraid of what was in there.

My heart sank.

Their performance outside made me even more uneasy.

There must be something more powerful up ahead, and if it weren't for the fact that we really couldn't find a way out, I wouldn't have been able to go to this place.

Cui Hao was lying behind me and saw me stop and push my ass.

"Go on! This place is suffocated, climb forward as soon as possible to see if the space can be larger, fat man, I am about to be unable to climb. ”

I nodded, and immediately picked up speed.

The narrow passage gradually expanded as we crawled forward, and gradually the upper and lower spaces became more than a meter high.

We could barely straighten up and crawl forward, and I breathed a sigh of relief and looked back at Cui Hao.

At the same time, I shone a flashlight at the entrance where we had just crept in.

Since the passage is not straight, we made two turns, so the entrance was completely out of sight at this point.

But I didn't see those strange bats chasing after me.

I breathed a sigh of relief and couldn't help but turn around and lie on the ground, taking a breath for a while.

"Fatty, don't climb yet, let me catch my breath. I almost couldn't breathe from the bats just now, and I want to rest for a while. ”

Cui Hao obviously had an idea, and when he saw me lying down, he also turned over with me, and just lay down in the underground passage.

"Who made this place, how could they dig up a palace like this, and make it weird. If this is the emperor's tomb, wouldn't it be better for him to make some gold, silver and jewelry, and build this place magnificently, than in such a dark and narrow place? ”

I shook my head, how can these people now grasp the thoughts of those emperors.

I can tell that this is definitely an imperial tomb.

Otherwise, with the identity of other people, it is absolutely impossible to build such an underground palace underground, and there is a large hall in front of it, and even the scene of a hundred officials and courtiers is built.

But which emperor's whim was here, because there is no written record, so I can't check it.

It's just that it seems that this emperor must have his own plans when he built such a place.

After resting for nearly a few minutes, I also temporarily cleared my mind and my body was much more relaxed.

I patted Cui Hao beside me.

"Let's go, keep crawling. This place is not to be left for long, it is too cold. ”

Although it was comfortable to lie on the ground, the passage under the ground was extremely cold, and I couldn't help but shiver from the cold.

I don't know where to keep pouring a cool breeze into it, and I can't help but shiver a few times when it freezes.

However, there is wind, and it seems that there should be a way out ahead.

If you want to keep climbing, you will definitely be able to find the exit.

Cui Hao barely got up from the ground under my urging, and then continued to climb forward with me.

Neither of us dared to waste time, and as fast as we could, we made several more big turns along the passage.

Faintly, my flashlight shone at the end of the narrow passage in front of me, and a little light seemed to appear.

"Ahead, front seems to be an exit."

It's just that this bright light instantly caused me to feel uneasy in my heart, this is a hundred meters deep underground, and there is no living action at all.

How can there be a bright light ahead?
