After eating, everyone went back to the police station. Luo Tian hugged Luoyang and walked in front with Bai Chi. Zhan Zhao and Bai Yutang walked side by side in the back.

"Cat, what did you find?" Bai Yutang was curious.
"Hmmā¦" Zhan Zhao thought for a while, and asked Bai Yutang, "Xiao Bai, do you think we should let Fang Wo perform a polygraph test, or should we not let him perform a polygraph test?"
Ā
"Didn't you say that he can't be tested with the polygraph, but he has to be tested with the polygraphā¦" Bai Yutang looked at Zhan Zhao, "It's a dilemma."
Zhan Zhao nodded and laughed, "Then, for example, Fang Wo passed the polygraph test, and the trial turned out that he was not guiltyā¦ and then he was released. Then another murder happensā¦ what will happen?"
Bai Yutang was taken aback and nodded knowingly, "I understand that when that time comes, Lu Liang will become the target of public criticism, and his theory will be made fun of!"
"Thenā¦for another example, if Fang Wo's polygraph test failed, he will be found guilty in the trialā¦ After that, there is another Ripper case." Zhan Zhao continued to ask, "What will the result be?
Bai Yutang nodded, "When the time comes, the police will be the target of public criticism. We have been busy for a long time and we have caught the wrong person!"
"Finally." Zhan Zhao smiled, "If we release Fang Wo first and the Ripper case continuesā¦ we catch Fang Wu again, and the case still doesnāt get closedā¦what is the result?"
Bai Yutang smiled and shook his head, "People will definitely think that the police and psychologists are stupid."
Zhan Zhao concluded, "No matter what you do, it will raise people's doubts about criminal psychology's participation in criminal investigation investigations."
Bai Yutang was taken aback for a moment, "Cat, so there hasn't been a Ripper case recently?"\n
Zhan Zhao smiled slightly, "Fang Wo is just a process. No matter if he is imprisoned or released, even if he is shot in the endā¦ As long as the murder case happens again, the murderer's ultimate goal will be achieved."
"That Lu Liangā¦ was just being used as a gunman." Bai Yutang frowned, "He is being used but yet he is still helping them.ā
"I think we should check Lu Liang's social relations and the people he often contacts." Zhan Zhao said, "Alsoā¦ In this world, nothing happens for absolutely no reason, especially extreme things. ."
"You mean, the purpose of this murderer's behavior is very clear? He hates criminal psychology?" Bai Yutang said, "He laughs at the police and hates psychologists. He is very familiar with medicine, at least to understand the structure of the human bodyā¦"
"There are many more." Zhan Zhao suddenly said seriously, "Xiao Bai, in fact, I happened to be researching something recently.
"What have you been researching?" Bai Yutang was curious, "There were no cases a while ago, but you looked very busy."
"I have been studying how to humanize certain behaviours!" Zhan Zhao said.
Bai Yutang said with admiration, āThen you should put your research into human words. I might be smart but the scope of my understanding is limited to humans.ā
"Go away!" Zhan Zhao glared at Bai Yutang, thought about it, and said: "For example, a murderer kills a personā¦ Then he has criminal motives, criminal places, criminal acts, Witnesses and so on, and the victims also have social connections, reasons for being the victim, and so on."
"Yeah." Bai Yutang nodded, "It makes sense."
"The large number of serial killers, extreme felons, and heinous people that we come into contact do not hate only one or two people." Zhan Zhao said as he walked, "They hate a group of people who have something in common. In other words, what they hate is a kind of behavior. In our current case, whether the murderer kills or harms people, it is because he hates somethingā¦"
"Understood!" Bai Yutang laughed, "You mean to imagine this behavior or thing as a person. For example, this time the criminal hates criminal psychology. That is to say, criminal psychology is the victim. Then he has his social circle, characteristics, places he frequents, what kind of people he might offendā¦ Cat! Not bad!"
Zhan Zhao smiled, "Sometimes things that are too scattered can make people confused, but if the scattered things can be combined, then we have clues to check!"
"We used to look for patterns from the victims, then find clues, and finally find the murderer." Bai Yutang understood, "What you study is to abstract the victim and directly define the scope of the murderer's possible existence! This method is a great way to deal with clueless cases. Itās great!"
Zhan Zhao stretched out his hand and patted Bai Yutang's shoulder with satisfaction, "As expected of Captain Bai, amazing understanding and analysis ability!"
"Let's go back and determine the possible range of that person. There won't be too many people like this. We can keep an eye on it!" Bai Yutang exclaimed excitedly, "Letās go Cat! There is work to be done!"
Bai Yutang and Zhan Zhao hurried back to the police station. That night, all the SCI officers worked overtime. Everyone browsed a lot of information. Zhan Zhao listed the following conditions for the culprit:
1: Direct or indirect contact with Lu Liang, extremely supportive of his theory, and their remarks about it are quite provocative.
2: They have done some research on psychology. They have had some articles that have been published in newspapers; the early ones were in support, and the later ones were against.
3: They have joined multiple psychology forums, in which they often appear at the beginning, but rarely appear in the later stages.\n4: There is a certain chance for them to come into contact with the corpse
5: They have some medical knowledge or some knowledge of human body structure
6: They are young, strong, and taciturn
7: Their career is not successful but it has a certain degree of freedom, and their economic conditions are average.
If five or more of the above conditions are met, then it is sufficient. After a whole night of investigation, the crowd identified 3 suspicious people. One is Lu Liangās student, Wang Le. He graduated last year and stayed at the school. He has been working as Lu Liangās teaching assistant and studies medicine. One is a netizen who often appears on Lu Liang's personal forum, Luo Xinyao. She is a trainee doctor and a fan of psychology, but her comments are very radical. The last one is called Zou Long, a teacher in the infirmary of Lu Liang's school. He usually chats with Lu Liang very well and often drinks two glasses together.
"These three meet the conditions." Zhan Zhao looked at Bai Yutang.
Bai Yutang sent Ma Han, Wang Chao, Zhang Long, Xu Qing, Zhao Hu, and Luo Tian to monitor the three people 24-hours a day in shifts.
Bai Yutang, Zhan Zhao, and Bai Chi continue to look for information at the police station.
After following them for two days, the conclusion was that none of these three people feel normal.
On the third day, Fang Wo's polygraph was conducted on live TV.
Zhan Zhao and Bai Yutang watched Fang Wo's polygraph test in front of the TV. Fang Wo passed the polygraph test successfully.
"This brat." Bai Yutang dropped the remote control and shook his head, "Heās not easy!"
Zhan Zhao was silent, before saying for a long time: "Fang Wo is a master, his identity is definitely not simple!"
āCat, the next thing is the highlight, and then the result will come out in the afternoon!" Bai Yutang deployed a large number of police forces and was fully prepared.
In the afternoon, Fang Wo's trial concluded; the evidence was insufficient and he was acquitted!
The result of Fang Wo's trial caused three waves of discussions in the news media. However, there was no one in the SCI office. They were all out in the field, ready to go.
That night, the three suspects all went out at the same time. After meeting each other, they all went to the same place ā Lu Liang's house.
When Bai Yutang and the others rushed into Lu Liang's home, Lu Liang was already on the ground, and the scalpel in Luo Xinyao's hand had almost been inserted into Lu Liang's stomach. All three were arrested.
It's just strange that even though Lu Liang's eyes are full of pain, he was unable to make a sound. Nonetheless, he was still able to struggle and move around.\n\nZhan Zhao helplessly said, "Generally pure theoretical sciences related to human behavior are very dangerous, like psychology and religious studies. Once someone deviate from the original objectives and go to extremes, they can become a tool to instigate and control people. In this world, there are practically no individuals who have no weaknesses and no psychological problems. If they have weaknesses, they will definitely be used by others."
"I always feelā¦like this case is not over yet." Bai Chi said suddenly, "I don't know what the ultimate goal is."
At this time, the door of the office was pushed open, and Bao Zheng and Lu Fang walked in.
"Bao Sir?" Bai Yutang looked up, "What's the matter?"
Bao Zheng nodded and said, "SCI has been established for a year, and many cases have been cracked. This time, the Ripper case is solved beautifully. To commend our police department for its contribution to the public security of S City, its famous politicians and business figures will hold a grand banquet tonight. They wish to thank us.ā
Bai Yutang and Zhan Zhao glanced at each other. Just as they wanted to say something, Bao Zheng glared at the two of them. "There are a lot of high-level people attending, so don't even think about it! Everyone has to attend!"
The two of them were completely powerless.
"Itās at seven o'clock tonight, on the top floor of the International Hotel!" Bao Zheng glanced around the crowd, "All the SCI members must dress nicely. If anyone dares to refuse to go, I will kick you out of the police force!" After speaking, he turned and left.
Lu Fang smiled to everyone, and whispered, "I knew it would be useless for me to talk. Bao Sir is still more overwhelming!" After speaking, he left with a smile.
There was a moment of silence in the SCI office. Everyone turned to look at Bai Yutang and asked in unison, "Boss, what does it mean to be dressed up nicely?"
Bai Yutang scratched his head, "Probably what you wear when you attend a wedding or formal event."
Everyone was silent. When they looked at their watches, it was almost seven oāclock. Bai Yutang waved, "Go home and change clothes!"
Zhan Zhao and Bai Yutang also reluctantly went home to change clothes.
"Xiao Bai, doesnāt the International Hotel belong to your brother?" Zhan Zhao asked.
"Yeahā¦ it was the same place where Qi Lei shot was last time." Bai Yutang said with a lingering feeling of fear, "If another incident happens tonight then that big brother does not need to rent out the venue any more. He should open a funeral parlour instead.ā
"Don't talk nonsense. By the way, isn't your brother out of the country?" Zhan Zhao thought for a while, "When will he be back?"
Bai Yutang shrugged, "How would I know? Ask Gongsun, ohā¦"
"What's the matter with you?" Zhan Zhao heard Bai Yutang suddenly yell and leaned over to look at him.
"Cat, my eyelids twitched!" Bai Yutang also came over, "Come over and kiss me!"
