A few minutes later, the people who had been stripped of their clothes had been driven into the showers, and the soldiers had been evacuated from inside.

"When the door closes, these showers on the ceiling will spill the water down, so hurry up and have only five minutes to shower." As one soldier said this, the door between the shower and the changing room was slowly pushed shut by the other soldiers. Most people don't notice the anomaly, but Ayumi realizes that something is wrong.

The sound of the door closing...... Are there heavy rubber pads? She asked Chiha.

"Well, as for the effect, you'll see it soon." Chiba looked in the direction of the roof, but Ayumi didn't know what he was paying attention to.

The picture goes pitch black — presumably because the "bathhouse" doesn't have windows to let in light or any light sources like electric lights — but then a large number of human bodies are supernaturally translucent and reversed, providing an extremely good line of sight for Chiba and Ayumi standing between them.

"Click-" At that moment, there was a crisp sound of an object falling to the ground.

"It's on," Chiba whispered. "Look carefully at the people around you."

"Around?" Ayumi only saw that some people were a little uneasy because they were in the dark and kept colliding with the opposite sex with their naked bodies, but they didn't see anything else.

But then, an old man, who was still a little restless, suddenly began to moan. "Ah......h

"Hmm, poison gas!" It was a somewhat dull warning sound from another strong man after he hurriedly covered his mouth and nose.

Within seconds, everyone who had grown old enough to know what was going on was panicking.

And the youngest of the four children fell to the ground crying and distressed in such ignorance and without protection—this child was not as old as Ayumi and Chiba.

"What is this?" Ayumi hurriedly asked Chiba.

"Zyklon B, a powder form of an insecticide. Of course, a more familiar name might be cyanide, which translates to air to produce such a gas. Qian Yu looked coldly at the corpse that fell to the ground and explained. Don't be distracted and look at the emotions of the living. ”

Two men and a woman ran to the door, apparently trying to pull it open – but the door was deliberately not designed with a doorknob that could be opened from the inside, and the edge of the door was sealed with rubber pads, so there was no way to get started.

The old man gritted his teeth and hugged his granddaughter tightly in his arms, but the child could not bear the pain of suffocation, so he could only bite the old man's wrist to suppress his desire to breathe.

The outcome of death is the same, but the way in which you should resist torture before death is different.

"Why do you want to do it this way?" At this moment, the voices of female officers and male researchers who should not have been here rang out again - they should be outside this house at this time, so Chiba and Ayumi should not have heard them anyway. "Doesn't it affect the speed to poison them in this way, and then take the trouble of exhausting them?"

"And what are you going to do?" The researcher was stunned for a moment, and then asked rhetorically.

"For example, wouldn't it be nice to shoot them all en masse and kill them all?" The female officer asked such a question in a very pure voice, and then added an onomatopoeia. “biubiubiu！”

"This is actually the method we ruled out in the first place," the scientist said, and the slight sound of his hand stroking his long hair began. "Because it's so cruel."

"Cruel? Isn't it cruel to kill them with poison gas? Ayumi frowned, very dissatisfied, questioning the source of the sound that didn't really exist here.

"Cruel? Does it have anything to do with us when the means are cruel to them? Or should we care that the means of killing them are too cruel? And this was the question that the beautiful female officer continued to ask in her innocent voice.

"Huh?" Ayumi was taken aback. "This ......"

"No, no, no, you misunderstood, it's not that it's cruel to them - that's okay at all - it's that it's difficult for our soldiers to carry out such a mission for a long time." The researcher continued to touch his wife's body, smiling and explaining. "Killing two or three thousand people may be fine, but if you carry out the purge of hundreds of thousands of people, you will have to rotate many, many soldiers to avoid psychological problems. After all, in fact, even the special operations teams that have previously carried out relatively small mass shootings have had a psychological barrier in this regard: although they can understand our cause, they have killed about ...... per capita In the 300s, there were still quite a few cases where it was very difficult to continue to persevere. Although the rate of killings has not been affected much, the need for psychological counseling has increased significantly. ”

"And there's also the problem, as you know, it's easy to break up the body when you shoot it, and it's too cumbersome to clean it up at that time. That's why we ruled out the possibility of killing all of these Tutsi dogs with bombs in a confined space: even if the confined space doesn't cause the corpses to scatter and splash around within a radius of tens of meters, it's very difficult to clean up one by one, but it's still too inefficient. Moreover, explosives are also very expensive strategic materials and should not be wasted on such meaningless things. ”

As they did so, a nearby researcher motioned for them to turn their attention. "Section Chief, it seems to be over, and you can get ready to start a strong convulsion."

"Can't we go in now?" The female officer was puzzled. "I remember you said before that the means used by this group should be ......"

"Hydrocyanic acid, hydrogen cyanide gas generator."

"yes, but isn't that a poison gas, why don't we just put on gas masks and go in......"

"At high concentrations, you can also take the skin pathway, let alone if you have a wound or something." The researchers reminded each other. "Don't worry, this time the ventilation system is very powerful, wait a few minutes and you can get in."

"Cut," the female officer pouted. "Still waiting...... Now the corpse that goes in is still hot and soft, and it will be cold after a few minutes, which is not fun at all. ”

…………

This is not a historical material, but a neta [final plan]. As for the reason? Because Chiba pulled Ayumi over not to understand history, but to help her inject feelings when singing, so she specially chose one in Rwanda...... The superior slaughtered, and used more impactful content to make an impact on Ayumi.
