A few minutes later, the people who had been taken off their clothes were driven into the bathroom, and the soldiers had all evacuated from it.

"After the door is closed, these spray heads on the ceiling will sprinkle water. Take the time, and there is only 5 minutes to take a shower in total." With a soldier's speech, the door between the bathroom and the locker room was slowly pushed up by other soldiers. Most people did not notice the abnormality, but Ayumi realized that something was wrong.

"Is there a heavy rubber pad for this sound of closing the door?" she asked Qianyu.

"Well, as for the function, you will see it soon." Qianyu looked at the direction of the roof, but Arimi didn't know what he was paying attention to.

The picture was pitch black - probably because this "bathroom" did not have a window that could transmit light, nor any light sources such as electric lights - but then a large number of human bodies were supernaturally translucent and anti-white, providing extremely good sight for the Chia and Arimi who stood between them.

"Pick--" At this moment, a crisp sound of an object falling to the ground came.

"It's started," Qianyu said softly. "Look at the people around you."

"Around?" Ayumi only saw some people feeling uneasy because they were in the dark and constantly colliding with the opposite sex with their exposed bodies, but they did not see any other abnormalities.

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

"Well, poisonous gas!" This was a somewhat dull warning sound from another strong man after quickly covering his mouth and nose.

Within seconds, everyone who had grown enough to understand what this was was panicked.

The one among the four children who were too young fell to the ground while crying and distressing, and was not as ignorant as he was without anyone to protect him. This child was not as old as Arimi and Chiayu.

"What is this?" Azumi asked Qianyu quickly.

"Zikron B, the powder form of an insecticide. Of course, the more familiar name may be cyanide. This thing can be translated into air and can generate such poisonous gas." Qian Yu looked at the corpse lying on the ground and explained this way. "Don't distract yourself, look at the emotions of the living people."

Two men and a woman ran to the door, seemingly trying to open the door - but the door was specially designed without a door handle that could be opened from the inside, and there was also a rubber pad seal on the edge of the door, so there was no way to start.

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 bit the old man's wrist tightly to suppress his desire to breathe.

The results of death are the same, but the ways in which to deal with torture before death are different.

"Why do you need to use this method?" At this moment, the voices of the female officers and male researchers who should not appear here rang again - they should be outside the house at this time, so Chia and Arimi should not hear these sounds no matter what. "Isn't it very much that I have to poison them in this way and then exhaust them with trouble. Will it affect the speed?"

"Then what are you going to do?" the scientific researcher was stunned and then asked back.

"For example, if you kill them in a group, wouldn't it be better if you kill them?" The female officer asked such a question in a very pure voice, and then added an onomatopoeia. "biubiubiu!"

"This is actually the first method we ruled out," the scientific researcher said, and the slight sound of his hand touching his long hair immediately rang out. "Because this is really cruel."

"Cruel? Isn't it cruel to kill them with poison gas?" Azumi frowned and questioned the sound source that did not really exist here with dissatisfaction.

"Cruel? Does the cruelty of the means to them have anything to do with us? Or should we care about the cruelty of the means to kill them?" And this is the question the beautiful female officer continued to ask in her innocent voice.

"Hey?" Azumi was surprised. "This..."

"No, no, no, you understand it wrongly, it's not cruel to them - it doesn't matter - it's hard for our soldiers to perform such tasks for a long time." The researchers continued to touch their wife's body and explained with a smile. "It may be fine to kill two or three thousand people, but if the cleaning of hundreds of thousands or millions of people is carried out, many soldiers must be rotated significantly to avoid psychological problems. After all, in fact, even the special handling team that had carried out small-scale collective shootings before had had psychological barriers in this regard: although they could understand our career, when the per capita kills about 300 people, there was still a considerable number of cases that were very difficult to continue to persist. Although the speed of killing was not affected much, the demand for psychological counseling increased significantly."

"And there is another problem, you also know that shooting will easily destroy the body, and the cleaning work will be too troublesome at that time. This is also the reason why we ruled out that we used bombs to kill all these Tusi dogs in confined spaces: even if the body is not splashed in a confined space within a radius of dozens of meters, it is very difficult to clean one by one, but the efficiency is still too poor. Moreover, explosives are also very expensive strategic materials and should not be wasted on such meaningless things."

Just as they explained this, a researcher next to them signaled that they would turn their attention. "The section chief seems to be over and can be ready to start a strong excitement."

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

"Hydrocyanic acid, hydrogen cyanide gas generator."

"Yes, but isn't that a poisonous gas? Why don't we just put on gas masks and go in..."

"You can also go through the skin path at high concentrations, not to mention if you have a wound or something." The researchers reminded the other party. "Don't worry, the exhaust system this time is very powerful, and you can get in after waiting for a few minutes."

"Tsk," the female officer curled her lips. "I have to wait... The body that entered is still hot and soft. It will get cold after waiting for a few minutes, and it is not fun at all."
