Chapter 657 The Third Person
"Your theory can only be considered barely plausible."

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

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

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

"Could it be that there is a magical psychosis that specializes in murder?"

"You are right, and the problem is very serious. It has started to appear since the establishment of the Palace of Everything a month ago."

The administrator in yellow didn't intend to hide anything from this guy who was about to be detained and could no longer speak out.

"This kind of homicide has happened in all residential areas, some were quickly extinguished, and some outbreaks were out of control, and may even lead to the complete closure of the entire residential area.

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

"One is to suddenly go berserk and kill indiscriminately. We call it a 'berserker'. This situation is relatively easy to deal with, and the security team will deal with it quickly.

"Another type of patient behaves the same as usual, but sometimes tries every means to kill indiscriminately, and tries to cover up his crimes. We call them 'sleepwalkers'.

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

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

"We call it 'Contagious Sleepwalking Homicide Syndrome.'"

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

But this question is meaningless, and the other party can't admit it, so he swallowed his words back, and just asked with a teasing smile:
"Is it a bacterium or a virus? What kind of infection? Contact? Droplets? Is there a vaccine? Can it be cured?"

"The technical department has not given a conclusion yet, but the guess is that it may be some unknown virus that affects the nervous system, which may be similar to rabies virus, but of a more advanced type.

"No pathogen has been found, so it is impossible to have a vaccine for the time being. As for the treatment, there are already some effective treatments, but they are still in the experimental stage."

The manager answered cautiously.

"I don't know how it spreads. But no matter which residential area, the Internet is gradually increasing from zero. If you don't quickly isolate all possible infected people, homicides will increase exponentially.

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

The administrator's tone became serious.

The other party has already explained this, so Meng Fei decided to open up and have a talk to see the other party's reaction.

"If I'm not wrong, these patients have other symptoms. For example, they may not be able to distinguish red from green when they sleepwalk?
"The "Code" specifically emphasizes that residents can only wear green clothing, and the use of red items is strictly prohibited in the entire residential area. But in the clothes cabinet, there are obviously red clothes.

"There are also arrows for toilets at night. The rules say you can only follow the green arrows, but sometimes some arrows turn red.

"It's because sleepwalkers can't tell red from green, so you're trying to find all sleepwalkers this way?
"But the proportion of red-green color blindness in human beings is very high. The proportion of red-green color blindness in Xizhou people is higher than that of Qingmang, as high as [-]%. It is not acceptable to arrest people just because they are wrong.

"Real sleepwalkers can't distinguish between red and green only when they are sleepwalking. And sleepwalking has a high probability of happening at night.

"So those people who can correctly choose the color of clothes during the day, but are disturbed by the red arrow to go to the bathroom at night, will be picked out by you?"

"You're a bit smart."

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

"These rules are indeed for the purpose of discovering and isolating 'sleepwalkers' among ordinary residents in a timely manner. But you must also know that these alone are not enough. Otherwise, there would be no outbreak of murders from time to time."

“So you also put mirrors. Residents are forbidden to use mirrors. But the roads that lead to toilets and bathrooms are full of mirrors and surveillance cameras.

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

"But there are so many mirrors and surveillance cameras concentrated on the road to the bathroom, and there are security guards ambushing behind the mirrors to attack at any time.

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

While talking about his guess, Meng Fei observed the subtle information revealed by the actions and tone of the guy in full body armor.

"You are right!

"Infected people may become rampages when they see themselves or others in the mirror. Berserkers will kill people immediately. So it is dangerous to use mirrors in residential areas.

"Toilets and bathrooms are places that everyone must go to. Mirrors and monitoring are set up on the only way. Once someone turns into a violent person, the monitoring is easy to find and the security can control it immediately.

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

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

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

"And your case is clearer.

"The surveillance recorded that only the deceased and you entered the sanitation area successively. We counted all other residents in the residential area, and they all slept peacefully in the residential area.

"So the murderer can only be you. As for whether you finished it awake and then denied it, or you really don't know if you finished it while sleepwalking, we can only hand it over to our psychiatrist for confirmation."

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

Every time he wanted to slap the other party's self-righteous thoughts, Meng Fei wanted to raise his legs chicly, but unfortunately his feet were tightly bound by the restraint belt, and he couldn't move at all.

"When I entered the cubicle, I found that compartments 1, 2 and 3 in the first row were all red.

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

"I was in compartment 4 and heard a sound in compartment 3 next door. I didn't pay attention at the time. But thinking about it now, it was the sound of someone flipping over the top of the compartment and going from one compartment to another.

"That person is definitely not the deceased. Because when I entered the No. 4 compartment, the bloody steel sheet had been inserted into the roll paper barrel of the No. 4 compartment, and the deceased was dead.

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

"Oh, it's a pity that you can't prove what you said."

The administrator shook his head regretfully.

"Only the knobs on the doors of compartments 3 and 4 were red when our people entered the restroom. The doors of compartments 1 and 2 were not what you said they were, they were all green.

"All the security guards had surveillance cameras on them to testify. And the security guards immediately searched all the stalls and made sure that all the other stalls were clear.

"There are indeed traces of being overturned on the top of the partition boards between compartments 1, 2, 3, and 4. But we think that's the mark of your overturning.

"As for what you want to do, I don't care. I only care about the simple truth: there are only two of you at the scene. One is the deceased, and the other is naturally the murderer."

"No no no. The truth is not as simple as your mind. If I were the murderer, it would be too easy to escape your search."

Meng Fei replied with a smile.

"Whether it's monitoring or searching, you can only identify ordinary residents in resident clothing.

"You can't and won't want to identify the security personnel who wear the exact same uniform, carry the same weapon, and wear the same mask, right?
"So what would happen if the murderer dressed in the same clothes as your security personnel and mingled with them? You wouldn't be able to find out!"
