My younger brother pressed the elevator button on the tenth floor while listening to me half-reminiscingly finish telling him about the content of "Yangmei", and then pouted disdainfully: "So such a roundabout warning method must not be 'Dad', it is very likely to be 'Mom'." ”

I was in a trance and pulled out of my deep memories, thought about it for a while, nodded, squinted my eyes and tilted my head to ask my brother, "Anyway...... You said that the person who deliberately disturbed me on the fourth floor just now, could it also be 'Mom'? ”

The younger brother thought about it and analyzed it seriously: "Although it is very possible, it cannot be determined. That routine and boring way of doing things also fits the style of 'Dad', doesn't it? ”

I pondered it again and immediately agreed: "Indeed, 'Mom' doesn't look like she would do such a thing. ”

"But since you told Mom and Dad that you read the book, and I don't even know about it, then I can basically determine that the person who did the thing about putting the cardboard box in the elevator is 'Mom and Dad', not someone else who might be ambushed in this library." The younger brother touched his chin and said.

My eyes widened, "yes, there's probably someone else here." I've forgotten about this possibility. ”

The younger brother twitched the corners of his mouth helplessly: "...... As a science student, can you not be so unrigorous? ”

At this time, the elevator "ding" sounded, indicating that we had arrived on the tenth floor.

"Stick to both sides first, lest there be danger." My brother stood on the left side and motioned for me to hurry up and stand on the right side of the elevator like him.

I did. When the elevator door was fully opened, it turned out that nothing had happened, and the outside was a little abnormal.

And it turns out that the high floors really have good lighting. This floor deliberately uses floor-to-ceiling windows on the whole side, with a clean and simple design, a large amount of sunlight spilled through the glass, printed with an unobstructed view of the city of F, which makes people feel extremely comfortable.

"This layer should be more dangerous, let's not go our separate ways, it's better to stay together." I said to my brother in an airy voice.

My brother nodded in agreement, and we cautiously stepped out of the elevator together, heading to the left side of the elevator first.

This floor is divided into two large areas, on the left is a reading room and a study room where you can pick up any books, and on the right is an exhibition room where many biological specimens and valuable records and data are placed.

We weaved through the shelves and still didn't find anything out of the ordinary. Even every book was neatly arranged, and the entire reading room was so quiet that it was as if no one was there.

"Why don't we take a look at the exhibition room, it feels like they must have done something unspeakable in the exhibition room." The younger brother suggested softly.

That's what I mean. After all, it is an exhibition room with many precious specimens, and now that the caretaker is gone, it means that these specimens can be accessed at any time, and there are indeed many things that can be done.

We immediately turned around and walked towards the exhibition room. On the way there, I accidentally caught a very unnatural spot out of my eye.

I hurriedly stopped my brother, who was walking forward in a hurry: "Wait, look, it's so strange there. I pointed to a floor-to-ceiling window behind several rows of bookshelves in the distance and said, "Why are there curtains in front of this window?" ”

The younger brother also noticed. Indeed, only this floor-to-ceiling window is covered with a soft, semi-transparent green curtain, which softens the light in the vicinity.

He immediately showed an interested expression: "Let's go, let's take a look." ”

So we changed direction and walked towards the curtain. After bypassing the rows of obstructive bookshelves, we finally arrived at the curtain.

"Looks like there's something behind?" The younger brother squinted his eyes and frowned, and said, I have to say that the light here is extremely dazzling even if it blocks the curtains.

I quickly took out two pairs of sunglasses from my bag and put them on my brother and me separately - in fact, when I took these sunglasses at that time, I thought that the introduction next to these sunglasses said that they could protect against most rays and radiation, and I always thought it was very useful in case I encountered a chemical storm in the future, so I brought them with me. Don't forget to bring an extra pair for my younger brother next to me.

I didn't expect it to be used so quickly.

The younger brother put on his sunglasses and pulled back the curtains.

The glass window behind the curtain has the word "PH-03" written in large lipstick.

What does that mean......? My brother and I looked at each other for no apparent reason.

In short, deliberately hiding it will generally be useful. I pulled out my phone and set the light to capture the scene - it was a bit reflective, and I had to change the angle several times to focus on it.

"Alright, nothing else, right? Let's go to the exhibition room. "I put my phone away.

My brother looked around again, and after making sure that there was nothing there, he followed me again in the direction of the exhibition room.

We quickly left the reading room and came to the front of the exhibition room.

In front of the exhibition room there is a very ornate leather door that needs to be pushed open. But in this case, the design is very unfavorable for us. Because you can't figure out what's inside, you may encounter some danger in the process of pushing the door if you are not careful.

It is even possible to be injured by the infected wandering here, because as my brother said before, there may be other people in ambush in this library, and no one can guarantee that there are no people in it.

"I'll push the door, sister, you're standing behind me." My brother turned to me.

I shook my head resolutely: "You call me sister, why am I still willing to stand behind you obediently?" I'm here, and the elders should come first. ”

The younger brother's eyes rolled: "That's it, otherwise let's guess Ding Ke, one game and one win, whoever wins will push the door." ”

I flattened my mouth unhappily, shook my head and said, "No, it's not that you don't know that I am easy to lose when I guess Ding Shell from childhood to adulthood, which is not fair at all." ”

The younger brother rolled his eyes: "Then change it to whoever loses and who pushes the door, so that you have nothing to say, right?" ”

I thought about it for a moment and nodded approvingly: "Well, that's pretty much it. ”

As a result, I came out with rocks, and my brother came out with scissors.

"How so? Obviously, I'm still very confident that I will lose...... "I was a little bit struck and couldn't accept the result with my mouth open.

The younger brother triumphantly moved the scissor hand to his face and grimaced: "Who told you to come out of the stone every time the first hand, and then the second one will definitely come out of the cloth." I have seen through the way of thinking, and it is not up to me to control whether I win or lose. ”

I immediately jumped to my feet: "If you don't take you like this, isn't that cheating?" It's a foul, it doesn't count, let's do it all over again. ”
