Cui Hao glanced back at me, his eyes full of inexplicability.

"What's wrong?"

I stretched out my hand and pointed the way.

"Do you think that the lights on the road when we came here seemed to be a little dim, and why do I feel as if some of the candles have gone out?"

As I spoke, there was another dark patch in the road ahead.

Cui Hao's eyes widened.

"I'll go, as if the candle really went out."

Cui Hao hurriedly cleaned up the four treasures of the study on the table, quickly stuffed a batch into the backpack bag, and held the flashlight and didn't move forward.

"Let's go, let's see. Most likely, the candle is too short, and it should be burned to the end at this point. Let's go refill the candle and don't get lost again. ”

Cui Hao has a point.

The two of us have been here for nearly half an hour, and it is true that it has been a bit long.

It's not impossible that those thumb-sized candles will go out and burn out.

But for some reason, the warm yellow candle light coming through the shadows of these bookshelves made me feel uneasy.

The candle went out so strangely, as if it had been blown out by something, not quite like it was extinguished naturally.

Thinking of this, I took two steps forward, walked to Cui Hao's side, and grabbed his arm.

"Don't worry, the two of us will go together, in case of danger, we can take care of each other."

Cui Hao didn't say anything, nodded and continued to walk forward with a flashlight.

The nearest candle next to us had burned half the length of its knuckles, and it was still about two-thirds of the way down.

As we walked forward, the candle in front of us went out again.

Cui Hao quickly led me around the corner, around the two rows of bookshelves, and pointed the flashlight at the extinguished candles.

My heart sank, and I quickly drew my dagger and aimed it at the darkness ahead.

Cui Hao also immediately took out his weapon and pinched it in the palm of his hand.

In front of us.

The candle on the ground was clearly half the length of a knuckle, and it hadn't burned to the end, but it was extinguished.

It was clearly blown out by something.

Cui Hao's voice was all trembling.

"Who's up ahead?"

He carefully pulled out his lighter and lit the candles as he passed them to light them again.

There was a thin layer of ash on the original ground, which was covered with the two of us' shoe prints after being stepped on a few times.

But now there are still several chaotic paw prints scattered on it.

"Those rats!"

With just one glance, I immediately realized that it was probably the rats who blew out the candles.

Cui Hao nodded, following those messy paw prints.

The paw prints soon disappeared into a row of bookshelves and disappeared.

"They got into the shelves, got out of the cracks?"

Cui Hao turned around and quickly turned to the other side of the bookshelf.

I followed, but I saw Cui Hao's back stiff, and he was stunned and motionless.

"What's wrong with you?"

I looked over his shoulder to the ground.

I was shocked to find that there was only a column of footprints of me and Cui Hao here, which were left by us when we passed by before.

Other than that, the ground was clean, and there was no trace of the rats.

Cui Hao turned around and asked me stiffly.

"Are these rats fine? There are no footprints in the direction of the bookshelves on both sides, so could it be that these things will settle down in the bookshelf? ”

Cui Hao loves it more seriously, so he turned around and went to this row of bookshelves from top to bottom, touching the back of each book.

But naturally there is no gain.

His face suddenly became even more ugly, but I smelled something unusual in it.

"Fatty, don't worry. I think it's more good than bad for us, and if you think about it, these rats can't just disappear into thin air, so there's something wrong with this shelf. ”

I reached out and tapped on the wooden lattices on either side of the bookshelf, listening carefully to the sound inside.

"The support under the bookshelf is about half a meter high, and the outside is carved with lifelike patterns, I only thought this thing was just a special decoration of the bookshelf."

I crouched down and gently tapped on the lower edge of the tree, only to hear the hollow crunch of what seemed to be a half-meter-high support layer of solid wood at the bottom of the shelf.

I looked up at Cui Hao.

"What else is there not to understand? It's empty here. ”

I roughly estimated the height of the support layer under the bookshelf, and more than half a meter was enough to drill into one person.

No wonder we can't find a way out, and these rats are haunted.

They didn't just punch through the walls and dig holes for themselves.

Even the bottom of this bookshelf was deliberately hollowed out, leaving a special passageway.

It would have been almost impossible to spot this unless I had looked closely.

Cui Hao was suddenly thoughtful.

"I'll go, what kind of people dug a passage here, and where is the entrance?"

He also squatted down with me, reached out and knocked on the support layer, and it was really empty.

Cui Hao's eyes were full of excitement.

"This makes sense, otherwise such a large building, how could it be just these three houses, it seems that there is no room here. Let me look and see, where is the entrance? ”

Cui Hao excitedly knocked left and right, trying to find the direction of the entrance.

I followed him and observed.

As we focused our attention on the bottom of the bookshelf, neither of us noticed that the candle flame behind us had dimmed slightly.

Whew.

The surrounding light suddenly vanished, leaving only the two of us with the glow of flashlights illuminating the space in front of us.

The candles were all extinguished at the same time.

"Cui Hao, be careful."

I shouted, and quickly pulled Cui Hao to hide in the corner.

Raising my flashlight, I pointed it in the direction I had come.

The candle on the ground, which we had just lit, was extinguished again.

And this time it was not just one that went out, but all the candles in the whole room.

We don't dare to breathe.

Except for the slight gasping of the two of us, all that was left was our heartbeat.

It was a long time.

There was no other abnormality, Cui Hao couldn't help but shake his body, and the friction of the clothes made a rustling sound.

At the moment when the voice sounded, it was as if something had been flipped on a switch.

Suddenly the sky was overwhelming above us, and groups of dark shadows crushed down on us.

"Run."

I grabbed Cui Hao, quickly chased the candle on the ground and turned around and ran out.

Although the candle has been extinguished.

But the traces of wax on the ground still helped us point the way out.

However, the moment the two of us left the corner, the sound of the mechanism suddenly sounded around us.

The sound of clattering mechanical parts rubbing against each other is incessant, as if thousands of troops are gathering and rushing here.

"What the hell?"

I was so anxious that I didn't dare to stop dragging Cui Hao, and quickly rushed forward.

As I looked around on either side, there was a thud and I hit a bookshelf.

The momentum was too strong, knocking me to pieces, dragging Cui Hao and falling to the ground.

Cui Hao rubbed his ass and muttered complainingly.

"How can this still hit the bookshelf? Aren't all bookshelves arranged in a north-south direction? ”

I quickly grabbed Cui Hao and crawled backwards, away from the bookshelf in front of me.

The moment he said this, he also realized something, his face was pale, his hands were squeezing my arms tightly, and I grinned in pain.

"Fatty, you are smaller. You're so strong that you're about to break my elbow. ”

I shouted, and he came back to his senses and slowly let go of his hand.

Cui Hao dragged me up from the ground, and looked at the bookshelf in front of me.

"How is that possible? How is this possible? This bookshelf is all facing north and south, how can such a bookshelf suddenly appear in an east-west direction? ”

I looked down and shone my flashlight on the ground.

A cloud of wax oil was spread out in front of me in the middle of the floor, half of it was crushed under the bookshelf on its back.

Apparently, the bookshelf had been moved to this place, which covered the candle oil that had been scattered here.

"Cui Hao, this bookshelf will move. It seems that the sound of the machinery we just heard should be the bookshelf moving in its position. ”

I looked around, dragged Cui Hao to raise the flashlight, walked around a bookshelf, and walked to the other side.

My heart sank.

"As expected, look at this. The layout of the bookshelves has also changed, which means that all of the bookshelves have been relocated. It's impossible to go out again with the markings we made earlier. ”

Cui Hao's face was gloomy, and he hurriedly pointed to the candle traces on the ground.

"Then let's look for the traces of these waxes, and maybe we can find our way out through these marks."

I nodded, not wanting to break Cui Hao's confidence. But in fact, I have thought about this method for a long time, but I don't have much hope in my heart.

The bookshelves here have changed, and we don't have pen and paper around us......

"Fatty, give me everything you just hidden."

I immediately beckoned to the fat man and reached for his backpack.

I almost forgot.

The fat guy had just stuffed all those four treasures of the study into his bag, and he could just hold things to mark them up now.

Cui Hao reluctantly opened his backpack and took out a jade pen from it.

He pinched the jade pen and refused to let go for a long time.

"This thing is very expensive, if you use it, maybe it will be discounted, I ......"

Before he finished speaking, I snatched the pen and took out the ink table in his backpack.

"Don't talk nonsense, we'll use this to mark the shelves around us later. You can also find a blank piece of paper and draw a rough top view of the place. ”

Although I don't know the layout of this place yet, I have already walked with the fat man here twice before.

So you have a rough idea of the original space, as well as the number of rows of these bookshelves.

Nowadays, even if the position is shifted, I can use pen and paper to roughly draw the distribution space under the ground.

As long as they don't continue to displace, sooner or later they will be able to find their way out.
