"How do you fish this, is it a dragnet investigation?" Jiang Chao sighed, "To be honest, I don't think there is enough time to visit and investigate." ”

"yes, so we need to get some people out and talk."

"Huh?"

"If we are very sure that there will be the next live broadcast, that is, in this school or in this whole city, there are still people who may be convicted, we can find out these people and talk about them through some methods."

"The question is, do you have any psychological ways to find people quickly?"

"Math, to be exact."

Lin Chen took out three pieces of paper from his pocket, which were the things he had been carrying with him today, and now it seemed that he was glad that he hadn't thrown them away because of trouble.

"Borrow the dynasty to use." He said to the Torture Conglian.

"Why are you so polite, as long as you don't get killed, you can use it any way." The torturer replied with a smile.

The young man sitting next to him raised his head from the screen, still holding a signature pen in his mouth, obviously still studying how to phrase it in order to catch those perverts: "Boss, I can easily betray like this, you know? ”

Lin Chen spread the three pieces of paper on the table and said, "In fact, as a result of Guòmmpi, we found that Wang Shishi, Xu Haozhen, and Jiang Liu all have similar personality traits, so we can use this trait in turn to screen out possible people." ”

"Find out who might be attending the next death livestream?" Wang Chao lay back on the table in the next second, "There are 30,000 teachers and students in Yongchuan University alone, and you want to find three people to participate in the next live broadcast here?" Ah Chen, don't say it, this is really looking for a needle in a haystack. ”

"You're saying that you should first screen out people with social introverts with a score of 70 or greater?"

Lin Chen nodded, after what had just happened, he didn't have any surprise that Xing Conglian actually remembered the keywords and scoring criteria.

He glanced at the dynasty, and the boy consciously spit out the pen in his mouth, and did not forget to wipe the bite with his T-shirt.

After taking the pen, he drew a large circle on the paper and explained, "Suppose this is a ......group of people with high scores of introverted personalities," and then he drew a small circle that intersected with it on the edge of the big circle, "This is the person who may have committed the crime." He said, handily blacking out the intersection of the two circles, "This is a potential group of people that we might be able to identify." ”

"I got it! This is for me to hit a database first, get out the information of this test, and then screen out the students who scored more than 70 in this test, so how many people are there? ”

"What a library." The sentence from Lian knocked on the dynasty, "We can pass guò due process to adjust the number jù." ”

"A score of 70 is about two standard deviations on the mean, so, conservatively, there will be 4% of the abnormal population." Lin Chen then replied.

"Then even if you only screen Yongchuan University, there will be 1,200 people!" Dynasty exclaimed.

"Is there any other way to narrow it down?" The criminal servant asked.

"Yes." Lin Chen replied very dryly, "Take another personality test." ”

Several of the suicides in this case all showed the characteristic of a change in their personal personality, so the students who showed a change in their scores in the second personality test were suspicious.

"I see." Torture Conglian said.

"However, there is still a problem." Lin Chen looked at Xing Conglian, "Suppose we conduct a personality test on students with great fanfare, won't we startle the snake?" ”

"It's not a big problem, and now that there is such a strict suicide incident in the school, isn't it normal behavior to check for students' mental health problems?" Hearing Lin Chen's concern, Xing Conglian continued with a smile, "And, when you really identify suspicious students, isn't it just enough to use this as an excuse to interview them?" ”

Xing Conglian's words made Lin Chen a little speechless: "You are really ......"

"What is it?"

Lin Chen shook his head, expressing helplessness.

"The old treacherous and cunning, insidious and cunning, especially shameless!" Comrade Wang Chao replied with great justice.

Xing Conglian didn't seem to care about these comments, his brows furrowed slightly, and he asked Wang Chao, "How long will it take for you to complete the initial screening?" ”

"It's going to be fast."

"How much time will it take to implement the second policy?" He asked Lin Chen again.

"The test time is about an hour, but the process from organizing the staff, arranging the test location to notifying the students to take the test is relatively long, and the student base is huge......

Hearing this, the convict glanced at the time: "It's 16:37 now." ”

"Yes, it's almost time to get off work, even if you notify the counselor now and arrange the test, it will probably start around 19:00 for the first batch of students to test."

"Do you have an estimate of which department and grade level are the students we are looking for?"

"In fact, there will be no significant difference in the scores of students in different departments, but the proportion of students in the Department of Psychology who are mentally unhealthy is relatively high......"

The torture servant couldn't help laughing: "Is this a self-complaining?" ”

Lin Chen picked the corners of his mouth and continued: "According to the number of our school, there are also students from the School of Medicine and the School of Chemistry......

"How many students are involved?"

"Report to the boss, a total of 3,158 people." Comrade Wang Chao quickly replied.

"Meaning, no matter what, you can't finish the test today, right?"

"Even if you have 20 classrooms at the same time and 800 students take the test, it will take five hours to complete."

"It's going to be tomorrow morning at the earliest."

But even tomorrow morning, 20 hours have passed.

Xing Conglian nodded and continued to ask, "Can you narrow down the scope a little more?" ”

"From the point of view of grades, freshmen have just taken the entrance test, and there is no need to take another test, and many seniors have started internships, no longer on campus, and are directly excluded, so it is good to choose sophomores and juniors directly."

As soon as the two of them finished speaking, they only heard Wang Chao knock down the enter key neatly.

"That's 1,342 people in total!"

It was indeed a pleasure to work with efficient partners: "I need to ask you to pick out the sophomores and juniors of the Faculty of Psychology, the Faculty of Medicine, and the Faculty of Chemistry, and then pull a list for me. Lin Chen said.

"Small." When the young man heard this, he tapped on the keyboard a few times, he looked at the generated number, glared, and said to Lin Chen, "Ah Chen, don't say it, your psychology department is really special." ”

"yes, I've always been weird." Lin Chen shrugged his shoulders rarely, and said, "Send me the list of these people, resumes, and test results." ”

"It's already been sent."

In short, Lin Chen probably understood why the torturer had to take the dynasty with him, it was really too useful.

After the boy finished speaking, he took out a tablet from his backpack and handed it to him: "You can use this to see." ”

"If we have this list in hand, can't we cross-compare the circle of friends of the 6 deceased people in this case to see if there is any overlap?" Jiang Chao suddenly asked.

"Yes, yes." Wang Chao took out a piece of candy and threw it into his mouth, "Why don't you find someone to do it, I still have a lot of things to do." ”

Even if it is a very relaxed and leisurely dynasty from beginning to end, it is also under pressure to investigate the case until now.

Widespread population screening and tight deadlines are almost inherently contradictory.

He continued to connect to the dark network, and pressed the refresh button a few times in some irritation, as if this would get a response from someone on the other side of the network.

"If Captain Jiang has a list, can you help him do a comparison and analysis?" Lin Chen pressed the young man's hand and spoke softly.

"It's going to take a long time to compare, and there's no response from there, so I'm going to stare at the reply."

The boy was very rare and rejected him.

Probably because his abilities are almost impossible to use in this dark world, he is even more desperate to play a role and defeat something.

As if seeing through the young man's thoughts, Lin Chen shook his head and said, "You should do something more important." ”

"Did you hear it, wait a minute, let Ren Xian keep an eye on the reward, you can teach it, and the level will not be too bad." "However, if we do not receive a response within half an hour, we need to take some more extreme measures." ”

"What do you want to do?" Lin Chen asked.

"Our current fishing nets are too small...... Xing Conglian looked at Lin Chen, "The main thing is that you inspired me to find a needle in a haystack, assuming that the murderer behind the scenes is using the live broadcast to make money, then it is impossible for him to be too reluctant for newcomers to join, there are also a lot of underground forums on the dark web, we can write some theme posts, well......"

"Are you trying to say that I should imitate the tone of a psychopath, write a thread, distribute it on major websites, and stretch the fishing net?" Lin Chen was keenly aware of the traps.

"You're more professional." The criminal servant was a little embarrassed, so he took the initiative to say, "I can be responsible for the translation." ”

Although he was a little speechless, he had to say that the opinions of the criminal conglian were still very reliable, and he just wanted to answer, but he heard the other party say: "Does Consultant Lin know where the toilet in the office building is, please take me there?" ”

The torturer is probably looking for someone to talk to, and he has to take into account the mood of the other people in the room in detail.

Lin Chen went out with him, and sure enough, the captain of the criminal police didn't have the slightest intention of solving the physiological problem, so he just found a window, opened half a window, and then lit a cigarette.

"What's wrong with him?"

Lin Chen was a little surprised, he didn't expect that Xing Conglian specially called himself out to inquire about the dynasty's psychological condition.

"He must be nervous."

"Are you nervous?"

The problem changed too quickly, and Lin Chen couldn't react a little.

"Not yet."

Pale smoke rose up, and Lin Chen was a little uncomfortable stared at by him.

"Anyway, I hope you don't feel too much pressure, and if you have any problems, you can sue me." Finally, the torturer Lian spoke.

At that moment, Lin Chen suddenly understood the intention of the Torture Conglian, he shook his head almost helplessly, and the Punishment Conglian really passed through his head.

From beginning to end, Xing Conglian did not ignore the most critical issue, knowing that Zheng Dongdong had a grudge against him, and knew that Steward Chen, and could properly use these two people to set up a huge trap, such a mastermind behind the scenes, it seemed that he was too familiar with him.

"If you're curious, you can ask me for a drink after this case is over."

Lin Chen raised his head, looked into the eyes of the torture conglian, and said so.
