"Do you remember, do you suspect there is an invisible secret room in this attic?"

My breathing was suffocated and I immediately looked up at the rooftop.

The black smoke that had crawled into the crack of the door had completely floated to the roof. At this time, a ball was gathered above our heads. Only in the gap between the thick smoke, could we barely see the hidden door on the roof.

I said, "You said—where?"

He didn't say anything, and looked up at the rooftop.

The thick smoke was getting more and more, almost filling it with all the tops. Those who were rushing to avoid the hot temperature of the roof and the flames that crawled into the cracks from the door from time to time went up and were choked so hard that they could hardly breathe. I even saw many people fainted.

If this continues, everyone will die!

I hurriedly looked back at Xiao Yusheng: "Yusheng, do you know what is on the roof of this book collection loft?"

Xiao Yusheng was also stunned for a moment, looked up and said with a complicated expression: "There is indeed something on this library, but the master has never told us, and he doesn't let us touch it."

Even he didn't know.

If it is really as we guessed before, there is a secret door on it, which is a cleverly designed cladding, then it is possible that the entire library will fluctuate due to the cladding being opened!

but--

I turned around and looked around. The flames were not only burning through the cracks in the door, but even from the walls in all directions. All the students were trying hard to rescue the ancient books, and even their clothes were burned by fire. The smoke was rolling and the fire was burning. At this time, it was already a critical moment of life and death!

I gritted my teeth and said, "Okay, let's have a gamble!"

Wei Yang behind him was stunned: "What are you betting on?"

"Let's find a way to open the secret door on the rooftop, and maybe there's a glimmer of life!"

"That secret door?"

"right!"

"But, we don't have the key!"

Xiao Yusheng immediately said: "No one has ever seen that key!"

My heart also became ruthless: "I can only find a way to force it open! Now there is only this road."

Wei Yang looked solemn: "Then, what will be inside after opening it?"

“…”

No one can answer this question, and even Qinghan’s guess just now was just a guess. If the secret room does not really exist, if there is a secret room, but there is nothing inside, then our last little hope will be wiped out.

But we only have this hope now!

Seeing the flames around him getting more and more, Wei Yang also gritted his teeth and said, "Okay, let's have a gamble!"

After saying that, he turned around and pushed the people around him away to run up the stairs. Xiao Yusheng immediately stopped him: "Don't go up, even if he runs to the roof, he can't touch the secret door. We brothers have tried it a long time ago, no!"

Wei Yang's steps stopped again.

Indeed, we had all reached the roof before, and we couldn't touch the roof even if we stretched out our hands, let alone the secret door in the center of the roof.

When Chang Yanbai heard that he probably understood, he tried his best to protect the prince: "What should I do now?"

Wei Yang looked up again, and he walked back, walked to the center of the bottom of the building, looked up, then slowly squatted down, touched his boot with one hand, and pulled out his boot knife from it.

As soon as I saw it, I immediately understood.

He wanted to use his boot knife to open the secret door on the rooftop.

But--

I looked up at the top. The library was so high, and we could see clearly before. There was indeed a place similar to a keyhole on the secret door, but it was too small, almost only two fingers wide. At such a long distance, it was not easy to hit such a small keyhole?

Moreover, without the corresponding key, can a knife force the mechanical skeleton on the roof of the building be forced to open?

Qinghan also said worriedly: "Is this really OK?"

"We have no other choice!"

Wei Yang pinched the boot knife in his hand, and a little cold light shone with his fingertips. He looked up at the rooftop, and the black clouds pressed over the top, almost filling half of the attic.

Those who climbed up the stairs were choking and some even fainted. But the bottom was not feeling well. The door was burned red. We were like a few pieces of meat in an iron pot. Not only could we breathe, but the hot temperature also had to light up the clothes on our bodies. As the saying goes, Bai and the old Mr. Qi were the oldest, and at this time, they could no longer hold on. Nian Shen and their men immediately dragged the two old men back up the stairs.

Wei Yang still didn't take action.

He looked up at the top and could just vaguely see the secret door as the smoke rolled, but now, the black smoke has condensed a thick layer and there is no way to see the situation on the roof.

Now he can only do it based on his previous memory.

Sweat dripped down from his face one by one, and everyone was roasted to the point of blooming flesh. At this time, he slowly closed his eyes.

My breathing was also suffocated at this moment.

In an instant, all the sounds around seemed to disappear, and those who kept hitting the wall and shouting for help also disappeared, leaving only the rolling smoke in their sight.

And behind the thick smoke, the small keyhole, perhaps also the mechanism of the entire library, is completely invisible.

At this time, I also clenched my fists.

At this moment, Wei Yang suddenly opened his eyes and waved his hand suddenly!

A cold light flew out from his fingertips. It was his boot knife that instantly turned into a lightning bolt. Before we could even see clearly, we had quickly penetrated into the thick smoke above our heads, and even stirred a whirlpool in the center of the smoke.

It was that vortex that pierced the thick smoke above the head.

I suddenly opened my eyes wide, and in an instant, I saw the small hole in the center of the roof, and the cold light was already shooting at it quickly-

At this moment, my heartbeat stopped.

Everyone also held their breath and heard a sharp sound from the air, which was the sound of the hard friction between the iron tools, which was so sharp that it was uncomfortable. When they looked again, the boot knife was actually pierced in the tiny hole!

Falled!

Falled!

I could hardly contain the ecstasy in my heart and immediately grabbed Qinghan's hand. He was sweating profusely, as if a man who was about to drown had seen a life-saving straw, his eyes glowed.

With that harsh sound, we immediately saw that the roof of the library seemed to tremble slightly, and with a muffled sound, countless dust was shaken off.

Success?

Turn on that machine?!

We were all extremely nervous, but after that muffled sound, everything returned to tranquility.
Chapter completed!
