A group of air men walked silently through the corridor, the black and white tiles on the floor stretching forward. The glasses girl had been standing at the metal door staring at us, and I couldn't help but feel a little sympathy for her. The doctor didn't seem to pay attention to what was behind him, and his breathing began to grow rapid, and his steps became a little faster. When he got to the metal cylinder, the doctor stopped.

"What the hell do you think these metal cylinders are?"

No one understood what he meant. At this life-or-death juncture, does the doctor finally feel afraid? The doctor didn't wait for an answer from the crowd and went on.

"I think this metal cylinder is a garbage bin. Everyone has seen it on TV or in movies, and in the future of more advanced technology, garbage bins have become robots. There is no need for sanitation workers, only a few low metal cylinders with long wheels running around, and whenever they encounter any garbage, they will be caught and stuffed into the garbage can. ”

What the? Are these metal cylinders garbage cans? It is true that in terms of shape, it is a bit similar, and some people have made similar conjectures at first. But will it be of any use to our future trials? Besides, if the metal cylinder is a garbage can, then what are the sportswear men and others who were "eaten" by the metal cylinders before?

At this time, the girl in the baseball cap sneered and spoke.

"Do you want to delay everyone's time? I'll admit that what you're saying can be thought-provoking, but if we don't go any faster, we might not be able to catch up with the sun before it sets. ”

The girl in the baseball cap gritted her teeth as she spoke, unable to suppress her hatred for the doctor any longer. The ambition to be the leader of the rest and the desire to live are intertwined, and her young heart beats violently. The doctor didn't look as nervous as a girl in a baseball cap.

"Are you so expecting me to die?"

"What are you talking about? I don't understand well. "It's not my wish, it's everyone's unanimous request." Didn't you agree with it before? ”

"Let it be so."

The doctor shrugged his shoulders and moved forward to take the first step. His steps looked wobbly, almost difficult to get to a straight line, which couldn't help but be reminiscent of the stride of a drunkard. Because the doctor was constantly shaking in the hallway, it took longer than everyone expected to get to the metal cylinder.

The metal cylinder did not move.

The doctor swaggered in front of the metal cylinder, but it remained motionless. What's going on, is it broken? Or is it true that after eating a person, you won't eat people again?

"Sulfona, look at the soles of his feet!" Riko whispered to me.

I watched intently at the doctor's feet, and gradually, I saw a pattern in what seemed to be a chaotic pace. The doctor walks on the lattice on the floor as he can, and never steps on the line between the lattices. To be precise, the doctor will only step on the black lattice, but avoid the white lattice. Could it be that the doctor won't get the attention of the metal cylinder? I thought carefully about the deaths of the previous people.

The man in the tracksuit who died at the beginning, he died on the way to chase the male high school student, and I can clearly remember the male high school student wailing and then retching. But he couldn't spit out anything, only sticky saliva spilled on the white tiles. Wait, so it seems that the man in sportswear died on the white floor tiles. To be precise, the corridors of the hall are all white tiles, and the interior of the hall is all black tiles. If we set a rule to make an inference: the person standing on the white floor tile will be attacked, and the person standing on the black floor tile will be ignored. That way everything seems to make sense.

Because the inside of the hall is all black tiles, even if the girl with glasses sits in the trash can and looks at the LED screen, nothing will happen. But the man in the tracksuit, who had passed through the white floor tiles, was brutally eaten. So as long as we follow the doctor's example and walk on the black floor tiles, then will we be fine?

Thinking of this, I took a step.

"Sulfona!"

Riko shouted my name loudly and tried to grab my hand. I shook my head at her, there was no room for obstruction during the trial, or I might be punished by the gods. I followed the doctor's instructions and carefully avoided the white tiles. Sure enough, the metal cylinder also ignored me. The doctor looked back at me, nodded slightly, and walked on.

If you look closely, there is no pattern to the distribution of black and white floor tiles on the floor, but if you walk carefully, you will always find a continuous path. However, if you don't choose the path well, you may encounter "islands" surrounded by white floor tiles. I looked at the doctor with some admiration, and he was able to go on without hesitation. In fact, walking on the floor tiles still requires a high IQ, and the intelligence is too low to operate.

In fact, there are three ways to pass through this metal cylinder. The first method is to rely on his physical ability to force a roll past the metal cylinder like the man in black. The second is like the doctor and me, who carefully walk the black squares and don't step on the white squares. The third might be to cleverly organize everyone again, like a girl in a baseball cap, and then keep electing the victims.

- The scales of black and white are always swinging, giving equal weight to wisdom and strength.

Is the black and white balance worth it for these weird tiles on the ground? Then these three methods may just differ in the emphasis on wisdom and strength. The man in black completely relied on physical strength through the metal cylinder, and the doctor relied on intelligence to observe the law through the metal cylinder, so what about the method of the baseball cap girl? I think it's both. The girl in the baseball cap needs to use her wits to "dominate" the remaining air people, and at the same time, her body must not be too weak, otherwise she will be prioritized as a sacrifice for everyone. Or is it that the so-called "right" can actually be counted as a type of power?

Before I knew it, I had walked through the area near the metal cylinder. It seems that while I am thinking, my brain is also subconsciously choosing the right path to move forward. The doctor stopped where he was, and he looked at me.

"Looks like you've found out too."

Riko had told me that she couldn't talk to the doctor, but now I don't think there's anything wrong with it. There were just two of us, and the doctor couldn't interfere with my progress, so I didn't think he could harm me at all.

"Yes...... Will you be fine as long as you walk on the black floor tiles? ”

"To be precise, we should only go for black tiles." The doctor's expression was much kinder than before, "Do you remember the second rule of law?" ”

"I remember it...... All things should be in their proper place, and the judged must complete a migration. It is only when they recognize themselves that the door opens and the migration begins. ”

"That's right, the meaning of this sentence is that we air people should only exist on black floor tiles. When we recognize the fact that we can only walk with black tiles, the metal door will open. ”

"But people don't know to walk with black tiles, or no one will die. So why did the metal gate open? Halfway through my speech, I suddenly realized, "Could it be that the door is open because you think about the black and white floor tiles?" ”

"I think maybe that's it. It was because of this that I had the courage to test my conjecture in front of the metal cylinder. ”

"Then why don't you tell everyone? Tell everyone, no one will die here! ”

"If no one tries it themselves, will anyone believe it?" The doctor smiled wryly, "Besides, those who only want to run forward won't follow my advice." ”

I regained my composure, and the doctor was right. If it is a man in black, even if he knows the rules of black and white floor tiles, he may choose to break through for the sake of time and efficiency, because he is very confident behind him. Those who followed him probably felt the same way.

"You're willing to try to come along, I think you're amazing."

Hearing this sentence from the doctor, I couldn't help but be surprised.

"How so? I've always felt like I'm sluggish, and I'm just going along......"

"It is also a kind of wisdom to follow decisively." The doctor stared at me for a moment, "You and the girl next to you don't seem to want to reveal yourself. ”

"That's ......"

My heart jumped, and it wasn't until now that I remembered what Riko had said. If you accidentally catch the doctor's attention, it will be troublesome afterward. I don't care about myself, I can't let Riko be dragged in. This trial was not used at all, and everything was my fault.

"It's okay, I'm not interested in your purpose." The doctor seemed to see that I was nervous and waved his hand at me, "In this trial, there is no use in hiding. No matter what you do, you have to show your whole self when it comes to life or death. So I was prepared from the start. ”

"Is it a matter of life or death?"

"That's right, so you don't have to be presumptuous." The doctor smiled at me, "Everyone here has their own flaws, and if you want me to think a little more than others, you will stand in the same position as me." ”

Same position as the doctor? Does that mean leading everyone and making everyone listen to themselves? I can't imagine myself like that. However, there are other things in the doctor's words that make me care.

"What do you know more than anyone else?"

"I don't know, I guess it's just my guess." The doctor rubbed his temples, "Why do you think we can only stand on the black floor tiles?" ”

"Or we'll be eaten by the metal cylinder?"

"Then why is it doing this?"

Why? Isn't that a rule set by the gods? Like Riko said, this might be like a video game, so we had to go with the black tiles. But this is a trial, not a game, so is there any meaning in it?
