"No fun." My brother shoved me behind him, "It's a good game." We don't have time anymore, do we? ”

I struggled for a while, still pouting and standing behind him very unwillingly, but I couldn't hide the worry between my eyebrows.

"Don't worry, who am I, your brother. It's going to be fine. My brother comforted me, then put his hand on the doorknob, "I'm going to open it." ”

"One, two, three!"

The younger brother pushed open the door.

However, the world behind the door is much cleaner than we imagined.

No...... It should be said that it is too neat.

Because all the biological specimens are gone. Even the formalin-filled bottles that kept them were clean.

My brother and I were dumbfounded. To be honest, we have imagined many situations, but we never imagined that the one that would really appear in front of us would be the one now.

"Huh? Sister, look at this. The younger brother suddenly pointed to a place on the empty shelf.

I turned my head to see that it was a shelf facing us right on the side, but there seemed to be something on the shelf, and it was a little protruding from the side.

My brother and I looked at each other, cautiously entered the room, and walked slowly in the direction of the shelf.

The angle slowly expands...... When we finally saw what the protruding thing was, we couldn't help but smile wryly.

It's a row of books. Another row of books.

And...... It seems that they are all books related to chemistry, and the titles of the books are "150 kinds of metal cutting fluid formulation and production", "caustic soda production and operation", "200 cases of metal surface treatment agent formulation and preparation", "practical organic synthesis process research and development manual", "development and application of corrosion inhibitors", "coal indirect liquefaction" and "application of microreactor in organic synthesis and catalysis" and so on.

Is this playing with us?

"Chemistry...... I remember that the chemical books were on the seventh floor. The younger brother shrugged his shoulders, then frowned and asked, "Where have all those specimens been moved?" What are the specimens of the entire exhibition room for? ”

There was a hint of concern on my face: "Don't you think there are so many strange things going on in this library?" First, the books on the shelves were restored in front of me in a way that was simply unattainable, and now the entire exhibition room has been directly removed, leaving another row of books. It seems to be guiding us to the seventh floor, should we be so obedient and go over there to see the situation? ”

The younger brother shook his head: "I don't think it's impossible to do, it's just that we haven't figured it out yet, so we think it's amazing." Anyway, it's all here, so let's go to the seventh floor to have a look, we can't let the clues just break off, right? ”

I sighed, "I don't know if it's a clue or a trap." Maybe it's better for us to 'go back sooner' as the note said......"

My brother patted me on the back comfortingly: "What should I do if I go back to 'Mom and Dad'?" Don't worry, I'll protect you if you have something, and if you give up here, you'll definitely regret it later. Let's go over there and have a look, let's be a little more careful, okay? ”

I thought about it, but nodded helplessly: I really can't just leave "Mom and Dad" here.

So we walked to the elevator again, and our expressions were heavy.

Strangely, this time both elevators stopped at the seventh floor in unison.

It's really weird.

"How did I start to feel like I was on the scene of a horror movie." When the younger brother saw the number of floors of the elevator, he shuddered suddenly and muttered in a low voice. I couldn't help but feel a chill in my back.

"Otherwise, let's take the stairs, it's on the side, and it's only three floors anyway, so let's go downstairs." I proposed, somewhat uneasily.

"No, maybe there's something in the elevator this time. I'm going to see what 'Mom and Dad' are selling. The younger brother pursed his lips and pressed the downward button, then stood there quietly with his hands on his chest and his head down.

I hesitantly glanced at my brother and then at the elevator, opened my mouth, and finally said nothing, standing next to him with my hands folded and my head bowed quietly.

This is the elevator on the left. There was a "ding" sound, and my brother grabbed me and ducked to the side.

The elevator doors opened. Or nothing happened.

I mustered up the courage to look into the elevator. It's still a cardboard box, quietly placed in the center of the elevator.

"It's definitely playing with us." The younger brother gave an affirmative sentence.

I motioned for him to step back with my eyes, and then I stepped forward and gently picked the lid on the cardboard box.

This time, it was not a book, but a specimen. A specimen soaked in a bottle full of formalin, something familiar to me.

- Not a precious biological organ, but a rounded antennae with bone spurs.

A tentacle of Ono.

I sat down on the floor.

My brother was so frightened that he hurriedly stepped forward to help me, and then couldn't help but glance into the cardboard box.

His eyes widened instantly, and then he immediately reacted and comforted me: "This doesn't have to be Ono's, maybe it's other infected people?" Didn't you say Ono had changed back? ”

I shook my head, my face turned pale, my lips trembled and I didn't say anything for a long time: "...... The potency of the drug was unstable, and he could change it back at any moment. After a pause, he took a few deep breaths before adding, "And...... There are really very few infected people with bone spurs. You also said in Ye Yiming's 'friend's villa that only he and Ono's mutant form had bone spurs, so they could break the experiment box and escape from our school's laboratory. I've secretly observed in the lab before, and it's true that the tentacles on the other infected people in the lab are smooth and thornless. "And Ye Yiming is already dead, and when he died, he was still in human form, so this tentacle has ...... It's only Ono.

"......" the younger brother was also silent. After a while, I suddenly started to ask again, "You say...... Could there be a possibility, that is, Ye Yiming is actually not dead? In fact, Ono saw the past feelings, let him go, and didn't give him the final blow? "Because when we were in that villa, we were all wrapped in Ono's body, and we didn't see anything, and when we finally came out, there were only bloody corpses left around, and I couldn't recognize who was with whom, and he was fully qualified to really let Ye Yiming go.

"Impossible, Ye Yiming is the murderer of Sister Ono, how can Ono still let him go." The younger brother pursed his lips and immediately denied.

The light in my eyes immediately dimmed: "So, Ono really ...... him"
