Anyway, it's better to inform my brother about this soon.

I ran to my brother's area in charge of the search, and quickly found him, pulling him over and briefly explaining the situation.

But when I returned to the place I had just made, I found that the books that had just been piled up on the ground were now strangely gone. Not only that, but the original empty shelves have now been refilled. And the books that were filled back were not those biological simulation books that were placed on the ground, but books related to electronics and telecommunications that were serious and should have been placed here in the first place.

That guy didn't leave?! But I didn't see anyone just now?!

And restore these books...... In less than a minute since I came back, what the hell did the other party do?!

"Is there really something left here? It's not that sister, you read it wrong? My brother tilted his head and looked at me a little strangely.

"No, it's really here." I hurriedly explained to him, "A large row of books, probably from the 10th floor, has been moved here. ”

"But there's nothing here." The younger brother looked at the empty ground, "It's not that I doubt you, sister, but where do you say that such a large row of books will be moved?" ”

"I don't know." I scratched my head in frustration, "If I had known, I wouldn't be where I am now." ”

"At least you're still holding this note proving that the pile of books existed." My brother pointed to the crooked note in my hand, "Do you think it's better for us to be obedient and obedient, or go to the tenth floor to see what is going on?" ”

I shrugged my shoulders: "I don't need to ask, with your sister's curiosity, I won't sleep well at night if I don't go to see it." ”

"Me too," the younger brother narrowed his eyes and nodded, "then what are you waiting for, let's go." With that, he pulled me up and walked in the direction of the elevator.

"Wait, isn't this floor going on to search? Maybe the guy who put the book is still around. I hurriedly pulled my brother forward.

"But after searching here, maybe we'll miss some good show on the tenth floor. I think it's better to go straight to the tenth floor and see what the other party is hiding or trying to catch than to catch someone who can magically play tricks in front of us and get away with it. The younger brother pouted, and did not stop for a moment.

I thought it was reasonable, so I nodded and hurried to the elevator with him - the library was still powered normally for some reason, maybe it was because the "Mom and Dad" who came earlier had already done something.

Both elevators are on the 10th floor. We hesitated, pressed the up button, and stood there waiting.

The staircase on the right reacted first, with a downward arrow on the display, while the elevator on the left did not move.

"Hey, you said ...... There will be nothing. My brother swallowed and poked me.

I shuddered: "It's hard to say...... Why don't we climb the stairs. ”

The younger brother shook his head: "That's a lot of time, it's better for us to hide." ”

I gave him a blank look: "How to hide?" What if it's 'Mom' who comes down? You'll be found hiding anywhere, bet? ”

My brother also glanced back at me: "Isn't that just right?" Isn't that what we're here for? ”

"That was before discovering the book you saw." I sighed, "Mom is a 'mother' who can commit a crime at any time, and maybe she will ...... us too."

"So what do we do now, it's not that we can't find them, it's not that we can't find them." The younger brother flattened his mouth and looked a little tangled.

“…… The only way to do that is to find them first, and find out what they are doing with us while trying to make sure of their own safety. If you can't do it, you can follow them secretly. Anyway, we can't let them 'get lost' with us like this, so let's gamble." I rubbed the watch on my wrist and muttered with my eyes down.

"Well, I agree." The younger brother nodded and glanced at the display screen on the top of the elevator on the right, "Sister, it's almost down." ”

I also glanced at it, and it was already the 5th floor.

"No matter, it's obvious that the things in here won't be normal, so let's hide. It's better than standing here as a living target like this. "I must be godly, grab my brother and run behind the bookshelf closest to the elevator.

As soon as we turned into the back of the bookshelf and hid it, we heard a "ding" sound and the elevator arrived.

We look carefully in that direction through the gaps between the books.

Luckily, it came all the way down unimpeded, otherwise we would have had to think about it again if we stopped on some floor in the middle.

The elevator doors opened under our burning gaze. Inside...... Empty.

But there is a closed cardboard box in the center.

But to be honest, it's great that no one is here, and I don't really know what to do if "Mom" does come out.

But there was a cardboard box...... What kind of trick is this? What kind of medicine is sold in the gourd?

I look at my brother, will I go? What if it's a trap? If you don't go, it's not a good idea to stay here, we have to go up to the tenth floor.

And, what the hell is in that carton...... I always feel so concerned.

Finally, my brother and I agreed through eye contact, and together we ran towards the elevator, and successfully intercepted the elevator at the last moment when the elevator was about to close.

After entering the elevator, I asked my brother to press the "open door" button all the time, while I carefully prepared to open the box - this would ensure that if there was something strange in the box, we could rush out of the elevator as soon as possible.

I carefully picked open one side of the carton with one finger and took a sharp step back. When I realized that nothing special was happening, I took another step forward and jerked up the other side of the paper cover.

The contents of the cardboard box are actually boring, neither dangerous nor interesting - they are two books.

But the title of one of the books is intriguing.

It's called "Curiosity Kills the Cat".

Another book is called "Bayberry".

To be honest, neither book is of much use to us now......

"It should be that person who is expressing to us that it is better to give yourself a break and be more relaxed." I cried and laughed and held the book of "Bayberry", turned my head to my brother and said.

"Why do you say that?" Seeing that there was no danger, my brother released the "open door" button on the elevator, turned his head to look at me and asked suspiciously.

"Because I read this book, when I was in junior high school." I tapped the book rhythmically with my hand and watched my brother reply, with a hint of distantness on his expression.

Suddenly, there was a feeling of reminiscing about my youth, and I felt very nostalgic.
