In view of the results of the meeting and discussion, many people were taken by the special affairs department to conduct related tests the next day, including Luo Tingyun. But after testing them one by one, the person in charge of the testing didn't find anything special about them.
Whether it is instrumental testing or psychological testing, the results show that the psychological and mental states of these people are in a normal state. Now the people in the special situation department were even more puzzled. Since it wasn't because of psychological effects or mental burden, why did this group of people insist that they heard the neighbor's voice?
Zhang Haoran, who witnessed the whole process of testing, was also extremely puzzled. He even wondered whether some of these people were infected by the intrusion source, and then infected others a second time, which eventually led to the current situation.
However, the normal test results vetoed this, so this possibility was also ruled out.
Squatting on the ground, Zhang Haoran lit a cigar worriedly. The doctor in charge of psychological testing came out of the room and saw Zhang Haoran squatting on the ground, so he asked, "Ke Zhang, what are you doing here?"
Zhang Haoran glanced at him, and then expressed his doubts. The staff of the Special Affairs Department have all heard of the invasion incident, and after listening to Zhang Haoran's description, the doctor also found it strange. Originally, he just received a notice today that he needed to conduct psychological tests on several people, but he didn't know that such a weird situation existed.
After a little hesitation, the doctor said, "Ke Zhang, have you ever heard a word?"
Putting down the cigar in his hand, Zhang Haoran asked in confusion: "What word?"
"Mass hysteria."
"Mass hysteria?"
"Yes. The so-called mass hysteria refers to a psychological or mental disorder caused by a certain mental stress-related factor affecting each other among many people."
For Zhang Haoran, this explanation was too professional, and he couldn't understand it. So, he asked directly: "You mean, the reason why these people heard the neighbor's voice is because of this disease called 'mass hysteria'?"
The doctor nodded, and then said: "This possibility is not ruled out now. If other methods cannot explain it, I think mass hysteria is most suitable for their condition."
Upon hearing this, Zhang Haoran's face became serious. After he extinguished the cigar, he said, "How much do you know about mass hysteria?"
After thinking for a while, the doctor said: "This disease used to be relatively common, but now I haven't had much contact with it. I know more about it from books. According to the records in the books, there was a very serious case before. A classic case of mass hysteria."
"Roughly at a party, someone felt unwell after eating food, so he suspected that he had food poisoning. As time went by, his symptoms became more and more serious, and he began to suffer from symptoms. Vomiting and diarrhea, hovering on the verge of death at any time."
"After other people in the party sent him to the hospital, they also suspected that the food they ate was poisonous. Soon after, people in the party also developed symptoms of diarrhea, foaming at the mouth, and weakness of limbs. There were many of these people, They were all taken to the hospital.¡±
"After quick rescue at the hospital, the first poisoned patient recovered and was fine. But the strange thing is that the doctor didn't find any signs of poisoning in him. What's even more strange is that the patients who were sent later There is no sign of food poisoning by anyone."
"In the end, the hospital conducted a careful examination of these 'poisoned' patients, and found that not only did they not have any signs of food poisoning, but most of them were in good health. After getting this result, the hospital finally diagnosed them as mass hysteria. "
After quietly listening to the doctor's description, Zhang Haoran thought for a while, and then asked: "That is to say, no one was poisoned at all. It's just that the first person felt that he was poisoned, so that other people also thought he was poisoned?"
"Yes. This kind of illness is actually the result of psychological suggestion, which usually does not have much impact. But in some social situations, this kind of psychological suggestion is extremely contagious. Once blindly believed, and the person concerned Highly self-centered, then there will be a chain reaction, which will eventually lead to the occurrence of mass hysteria cases."
After reaching this conclusion, Zhang Haoran suddenly came to understand, and he said to himself: "That is to say, in this case, because a certain person's neighbor moved away, he spread the news everywhere after he found no one else. And because of wrong psychological hints, everyone eventually mistakenly believed that they had a neighbor. But in fact, that neighbor didn't exist at all?"
Hearing what Zhang Haoran said, the doctor obviously knew that his explanation just now was still useful, so he nodded heavily and said: "Yes, yes, yes, it is very likely that is the case."
"Is it normal for this kind of disease to appear?"
The doctor hesitated for a moment, and then replied: "Although it is relatively rare nowadays, I think it is quite normal. After all, it is also a psychological problem in essence."
The other party is a psychiatrist, since he has said so, Zhang Haoran has no reason not to believe it.
"Thank you this time."
Standing up, Zhang Haoran smiled at the doctor, who also nodded and smiled back. Back in the command room, when Zhang Haoran was considering whether to close the case with mass hysteria, suddenly a staff member in the command room said to himself: "Huh, what a coincidence?"
Noticing this situation, Zhang Haoran hurried over and asked at the same time: "What's so coincidental?"
The staff member was staring at the computer screen. When he turned around and saw Zhang Haoran approaching, he responded: "Chief, when I was sorting out the list of residents in that apartment, I found a very coincidental thing."
"What's up?"
"This Zhao Dahai also lives in that apartment."
Zhang Haoran was taken aback after hearing this, and the expression on his face froze instantly. The case that was already about to be finalized, under the impact of this sentence, many associations sprouted in Zhang Haoran's mind. Although he was not sure whether his association was correct, Zhang Haoran vaguely felt that this information might bring changes to the case.
After understanding this, Zhang Haoran hurriedly said: "Call out the information."
Soon, a resident registration form appeared in front of Zhang Haoran. Looking down from the registration form line by line, it didn't take long for all the information about Zhao Dahai's apartment in this building to be revealed.
According to the information in the resident registration form, Zhao Dahai bought this house two years ago, and he is the only one living in this house.
A married person living in an apartment by himself?
No matter how you think about it, this is a bit strange. What makes Zhang Haoran even more puzzled is that Fang Xianzhu's case has not yet ended, and now Zhao Dahai has appeared in the case in hand. Is this a coincidence, or are the two related?
After thinking for a while, Zhang Haoran asked: "There is no news about Zhao Dahai, when will the dead in the convoy be transported back?"
"According to the feedback from the team, it will take about four days."
"Four days? Okay, I see, remember to notify me when they arrive in Qingshui City."
After finishing speaking, Zhang Haoran glanced at his phone, and after realizing that it was getting late, he decided to have a meal first
Zhang Haoran never dreamed that Zhao Dahai, whom the entire Special Affairs Department is thinking about, is actually in Qingshui City, and he is even shopping in Qingshui City.
However, Zhao Dahai at this time is different from the one in the photo. His facial features have not changed much, but he is wearing a well-fitting black suit and carrying a black briefcase in his hand. Such a dress, coupled with his aging face, looks quite like a successful person.
But the problem is that Zhao Dahai has no color in his eyes, and the expression on his pale face is very stiff. Not only that, but his walking movements also look extremely mechanical, like a robot controlled by a program.
Zhao Dahai, who walked like this, became the focus of attention on the street, and many people cast curious eyes on him. But after seeing his attire, many people think that this is probably rich people playing performance art. Therefore, most people just take a quick look and then stop paying attention.
Just like that, stepping on mechanical steps, Zhao Dahai walked through one street after another in Qingshui City. Finally, he slowly came downstairs to the apartment where he lived.
He looked up at the apartment building, as if he was looking for where his house was. At this moment, a middle-aged man passed by him. The man glanced at Zhao Dahai, and then said in amazement: "Dahai?! It's really you. I was behind you just now, and the person in front looked like you. I didn't have the nerve to ask if it was you. I didn't expect it to be you."
Zhao Dahai slowly turned his neck and looked at the man. The man looked at Zhao Dahai's outfit at this time, and said cheerfully: "Yes, this suit suits you quite well. I'm afraid it will cost a lot of money? It seems that recently You made a lot of money, why don't you two go out for a drink tonight"
The speaking stopped abruptly, and the man looked at Zhao Dahai's pale and stiff face, and he seemed to feel something was wrong. So he asked, "Dahai, are you all right?"
And Zhao Dahai just stared at the man blankly, then slowly opened his mouth.
"roll."
There is no emotion in the hoarse voice. If others hear these words, they may feel angry or angry, but this man does not. He was taken aback for a moment, then his whole body trembled like sifting chaff, and then, the look of fear began to spread rapidly on the man's face.
After the man yelled "Ah", he fled in one direction desperately, as if he had seen a ghost from hell. Seemingly infected by fear, the man actually fell and dropped his wallet while running away.
But he didn't care to pick up the wallet, and after struggling to get up, the man fled further away, and the screaming in his mouth never stopped. The man turned his head while running, as if he was watching whether Zhao Dahai would catch up. Then, the horrifying and disgusting scene just now appeared in his mind: when Zhao Dahai said the word "roll", he saw a fat maggot in Zhao Dahai's mouth, and the maggot was still wriggling. ??The whole body trembled like chaff, and then, the color of fear began to spread rapidly on the man's face.
