"Your theory can only barely make sense."

Meng Fei's arms were always tied behind the chair, which made him feel sore, and his head also hurt.

"But there is one thing I don't understand. Even if the murderer is me, what is the motive? I have never met the deceased and have no grudges. Random killing? Why should I kill?"

In fact, Meng Fei already had a guess about what they thought was the "motive", but he just hoped that the other party would speak out and confirm his idea.

"Is it possible that a magical mental illness that specializes in killing people is popular here?"

"You are right, and the problem is very serious. It started to appear a month ago when the Palace of All Things was established."

The administrator in yellow had no intention of hiding anything from this guy who was about to be detained and could no longer speak.

"Such murders occur in all residential areas. Some are quickly extinguished, while others break out out of control and may even lead to the complete closure of the entire residential area.

"The murderer is often not the same person. It seems to be some kind of contagious disease. Once infected, the infected person will have two possible symptoms.

"One is to suddenly become violent and kill people indiscriminately. We call them 'berserkers'. This situation is easier to deal with, and the security team will handle it quickly.

"I only believe in a simple truth: since there are only two people at the scene, one is the deceased, and the other is naturally the murderer."

"This is because sleepwalkers cannot distinguish between red and green, so you are trying to find all sleepwalkers in this way?

"But the proportion of red-green color blindness among humans is already very high. The proportion of red-green color blindness in Xizhou people is even higher than that of Qingmang, as high as 10%. It's impossible to arrest people just because they see something wrong.

"You are right!

"That person is definitely not the deceased. Because when I entered the No. 4 compartment, the bloody steel piece was already inserted into the paper barrel in the No. 4 compartment, and the deceased was already dead.

"When I entered the cubicle, I found that cubicles No. 1, No. 2, and No. 3 in the first row were all red.

"When our people entered the restroom, only the knobs on the doors of compartments No. 3 and 4 were red. The doors of compartments No. 1 and 2 were not what you said, they were both green.

The administrator shook his head regretfully.

"Although we don't understand how it spreads, no matter which residential area it is, it starts from zero and gradually increases. If all possible infected people are not quickly isolated, the number of homicides will increase exponentially.

Managers answered cautiously.

Every time he wanted to slap the other person's self-righteous thoughts in the face, Meng Fei wanted to cross his legs in a cool way. Unfortunately, his feet were tightly tied with restraints and he could not move at all.

"The other type of patient behaves the same as usual, but sometimes he will do everything possible to kill indiscriminately and will try his best to cover up his crimes. We call them 'sleepwalkers'."

The manager's face was hidden behind a mask, and Meng Fei couldn't see his expression, but there was a hint of surprise in his tone.

The administrator's tone became solemn.

"Toilets and bathrooms are places that everyone must go to. Set up mirrors and surveillance cameras along the way. Once someone turns into a violent person, the surveillance can easily detect it, and security can take control immediately.

"So those people who can correctly choose the color of their clothes during the day, but whose route to the bathroom is disrupted by red arrows at night, will be caught by you, right?"

Meng Fei shook his head and answered with a smile.

"There are indeed traces of being climbed over on the top of the isolation board between compartments No. 1, 2, 3 and 4. But we think those are traces left by you climbing over.

"Because surveillance will record everyone's entry and exit, and there are no other exits in the health area, the suspicions will be concentrated in a small area.

"I was in cubicle 4 and heard a noise in cubicle 3 next door. I didn't pay attention at the time. But now that I think about it, it was the sound of someone climbing over the top of the cubicle and jumping from one cubicle to another.

“But there are so many mirrors and surveillance cameras placed on the way to the bathroom, and there are security guards lurking behind the mirrors to attack at any time.

But the question was meaningless and the other party couldn't admit it, so he swallowed his words and just asked with a smile:

"Can it be transmitted through killing? Is it a bacterium or a virus? How is it transmitted? Contact? Droplets? Is there a vaccine? Can it be cured?"

"At that point, all residents in the entire residential area will either be detained for treatment or killed. Other residential areas will also be affected."

"The technical department has not yet made a conclusion, but it is speculated that it may be some unknown virus that can affect the nervous system, which may be similar to rabies virus, but a more advanced type.

"Monitoring shows that sleepwalkers usually plan and implement murder plans after falling asleep. In some cases, they will be awakened. After waking up, they will not remember anything related to the murder.

"It means that this kind of change can be detected by surveillance. Once discovered, the infected person can be quickly arrested. So I guess, these mirrors will cause the infected person to become violent?"

While Meng Fei was recounting his speculations, he was observing the subtle information revealed in the movements and tone of this guy who was fully protected.

"As for what you want to do, I don't need to care.

"Not only that, even some infected people escaped the filtering of the mirror and completed the murder in the bathroom.

Meng Fei couldn't help but twitch the corner of his mouth. What he wanted to ask was, are you sure it's not a side effect of your master using nuclear radiation to try to change everyone's consciousness?

"These rules are indeed intended to detect and promptly isolate 'sleepwalkers' among ordinary residents. But you must also know that these alone are not enough. Otherwise, murders would not break out from time to time."

"But I know that when you rushed in, besides the deceased and me, there was another person in the bathroom."

"So the murderer can only be you. As for whether you completed it while awake and then denied it, or whether you completed it while sleepwalking, I really don't know. I can only leave it to our psychiatrist to confirm."

"We call it 'Contagious Sleepwalker Murder Syndrome.'"

"The pathogen has not been found, so there is no vaccine for the time being. As for treatment, there are already some effective treatments, but they are still in the experimental stage."

“No no no.

"An infected person may become a berserk when they see themselves in the mirror. The berserker will kill immediately. Therefore, using mirrors in residential areas is dangerous.

"If I'm not wrong, these patients have other symptoms. For example, they may not be able to distinguish between red and green when they are sleepwalking?

"The "Code" specifically emphasizes that residents can only wear green clothing, and the use of red items in the entire residential area is strictly prohibited. However, in the cabinet that supplies clothes, red clothes are clearly provided.

"After being arrested, sleepwalkers will strongly deny that they have done anything related to killing. It is as if they did not have self-awareness when they killed, and they were sleepwalking.

"The surveillance video recorded that the only people who entered the health area one after another were the deceased and you. We counted all the other residents in the residential area and they all slept peacefully in the residential area.

"You do seem a bit smart."

"So there must have been a third person in the bathroom at that time!"

The hissing camera above the gas mask was pointed at Meng Fei again.

"Since residents are prohibited from using it, it is obviously because the mirror will cause some kind of change that is not beneficial to the residents, such as an infection outbreak, or other problems.

"Real sleepwalkers cannot distinguish between red and green only when they are sleepwalking. And sleepwalking is most likely to occur at night.

"So you also installed mirrors. Residents are prohibited from using mirrors. But the only way to the toilets and bathrooms is covered with mirrors and surveillance cameras.

"And your situation is clearer.

"Oh, it's a pity that nothing you said can be confirmed."

"There are also arrow directions for the restroom at night. The "Rules" say you can only follow the green arrows, but sometimes some arrows turn red.

The other party had already explained this, so Meng Fei decided to talk openly to see the other party's reaction.

"All security guards have surveillance cameras on them to testify. And the security guards immediately searched all cubicles to confirm that no one was in any other cubicles.

"In other words, these compartments seem to be occupied, but in fact there are not. This means that someone deliberately closed the doors inside to lure me into compartment 4.

"The facts are not as simple as your mind. If I were the murderer, it would be too easy to escape your search."

"Whether it's surveillance or search, you can only identify ordinary residents wearing resident clothing.

"You can't and won't even think about identifying security personnel wearing the same uniform, carrying the same weapons, and wearing the same masks, right?

"What would happen if the murderer dressed like your security personnel and mingled among them?

"You can't even find it!"
