Ten minutes ago, Tannen walked into the small dark room next to the interrogation room and watched Yi Jiayi's interrogation with Fang Zhenyue and others.

Although everyone soon discovered that Officer Yi had turned off the radio function, fortunately, they could still see Liu Xujie's expression.

Everyone in the small dark room guessed what Jiayi was talking about with Liu Xujie.

Was she more patient and detailed than Fang Zhenyue in describing to Liu Xujie the process of the crime inferred by the police, so as to convince Liu Xujie that the police had indeed grasped all his criminal methods and evidence?

Or was she using special interrogation techniques to try to break through Liu Xujie's psychological defenses?

Or maybe she used some advanced criminal psychology techniques to dig deep into Liu Xujie's heart, and through her extraordinary understanding of the murderer, she gradually disintegrated his resistance and made him cooperate with the police to record his confession?

Just as everyone was guessing and recalling Jiayi's amazing actions and smart methods when interrogating the criminals before, Liu Xujie's expression suddenly changed when he was listening to Jiayi's speech on the small TV.

Everyone could not see Yi Jiayi's face, but only a particularly relaxed, particularly chic and comfortable back.

It was in this posture that the female police said something that made everyone curious, and violently peeled off Liu Xujie's hard shell, revealing an expression of surprise, suspicion, and shock.

Even gradually, everyone saw a fearful expression on Liu Xujie's face.

Tannen turned his head in disbelief and looked at Lin Wangjiu, who was very clear-headed. "Uncle Jiu, the suspect actually... really tensed all his muscles."

Uncle Jiu crossed his legs, and his expression was clearly saying: Of course, didn't I say it before, how could it be wrong~

"...The suspect made a defensive posture, he seemed to be very afraid of Officer Yi Jiayi, what did Officer Yi say?" Tannen couldn't help but stand up and wanted to go to the interrogation room to take a look.

Fang Zhenyue immediately turned his head and stared at Tannen, with his legs spread out, as if he would pull Tannen back if he opened the door.

Since Jiayi said that she wanted to talk to Liu Xujie alone, she must talk alone, and no one else could disturb her.

The look he gave Inspector Tannen clearly expressed this.

Tannen and Fang Zhenyue stared at each other for a while, but finally sat back in their chair and continued watching.

"Aren't you curious?" Tannen couldn't help but ask Uncle Nine, who was sitting leisurely beside him.

"What's there to be curious about? Eleven is always very stable in her profiling. Hasn't she scared the murderer every time? I don't know how strong the professional ability of a detective can be. I'm afraid he will think Yi Jiayi is evil." Uncle Nine laughed, turned around and continued to watch the small TV, continuing to observe Liu Xujie's expression.

Every time he followed Jiayi to do an interrogation, he was happy to see the murderer being scared to death by Jiayi's sharp description of the crime scene.

I don't know what kind of mentality this is, it's really strange.

"..." Tannen turned to look at You Zhaohua, the sergeant of Group A, who was also sitting very steadily. This sergeant was not from Group B, so he must be curious, right?

You Zhaohua met T's puzzled eyes, smiled and shrugged, "Yes, Officer Yi is so evil, he is very careful, and he can always find clues that others have not found. He is almost better than Sir Fang. Look how frustrated Sir Fang is now."

Tannen turned to look at Fang Zhenyue again.

"Don't talk nonsense, the Qianlima I picked is so powerful, I am so happy and proud." Fang Zhenyue crossed his legs and hummed leisurely.

Although Fang Zhenyue was not embarrassed, You Zhaohua still smiled happily.

"Don't you need to go back to work?" Fang Zhenyue kicked You Zhaohua's chair.

"After all, Tony has been borrowed by you for several days. He is very concerned about the progress of the case. I will accompany him to follow up and learn about Yi Jiayi's interrogation. It's a pity that there is no sound to listen to. How can I learn?" You Zhaohua shrugged with some regret.

Tannen looked at everyone with an expression of "it is natural for the murderer to be scared", and immediately felt like he had never seen the world.

He scratched his head, turned to face the small TV, and watched it more attentively.

After a few minutes, he couldn't sit still again.

Tannen really couldn't imagine what Yi Jiayi said that could make Liu Xujie stand up and run to the wall in fear, standing against the wall as

if he was punished. What did Officer Yi say?

How could he be so frightened that he seemed to have lost his mind?

At this moment, Tannen had long forgotten his previous competition with Yi Jiayi, and his thought that as long as he made a speech, Yi Jiayi would be surprised and admired.

Now, he was the one who showed surprise and admiration to Yi Jiayi.

Not only that, he was simply restless!

Curiosity had eroded his calmness, and because of his strong desire for knowledge, he kept poking at the frame of his glasses anxiously.

Although he was the only person in a suit in the small dark room, with such an expression, he was no longer the most gentlemanly and elegant man in the room.

"No wonder Jiayi is so strong, it turns out she knows criminal psychology. Look, she makes Liu Xujie look like a child, hey." As Jiayi's teammate, Sanfu was also proud at this moment.

Tannen stared at Sanfu for a few seconds, then turned to the small TV screen.

"Is our criminal psychology so broad and profound?" He whispered quietly, blinking his eyes, and his mouth opened slightly unconsciously.

At this moment, Tannen's awe of his subject became stronger than ever.

This subject is unfathomable, and he really hasn't learned it deeply enough. He should communicate with Yi Jiayi more often in the future, no, maybe he should be more humble.

Although the other party is a female police officer younger than himself, and has not studied this subject systematically abroad, her understanding and application of this subject combined with actual combat is probably much better than his. The

completely different reactions of the murderer before and after being interrogated by Yi Jiayi, and the mysterious and unknown interrogation method, made Tannen's worldview shift.

Tannen watched the next few minutes standing. Finally

, Jiayi reported to Fang Zhenyue in front of the camera that Liu Xujie could be interrogated further, so everyone rushed out of the small dark room.

Fang Zhenyue took Sanfu and Liu Jiaming into the interrogation room, and the others had to squeeze to the window of the interrogation room, or run back to the small dark room to continue watching the interrogation.

Next, although Liu Xujie still had some resistance, he finally confessed under the pressure of Fang Zhenyue.

This confession and the interrogation videotape, along with other evidence, were sufficient to bring Liu Xujie to court.

This difficult and long case finally came to an end.

Fang Zhenyue walked out of the interrogation room, stretched his waist, twisted his neck left and right, turned around and saw Yi Jiayi walking out, raised his eyebrows and asked:

"How did you make Liu Xujie so scared?"

Jiayi smiled, stood up straight, and answered very seriously:

"People like Liu Xujie seem to be calm and rational, but in fact he is a coward. The reason why he made such a detailed plan before killing people is not only because he is really smart, but also because he is actually very scared in his heart.

"On the one hand, he is very confident that his plan is foolproof and thinks he is an absolutely smart man. On the other hand, he is too weak to bear any mistakes.

"Arrogance coexists with inferiority and cowardice, as can be seen from the fact that he made detailed plans for several months before committing the murder, but did not care about leaving his fingerprints and footprints at the crime scene.

"For such a person, saying what the police found will not bring him down. But if you point out his own mistakes, that he could have done better, and that he is actually very stupid, he will collapse."

Arrogant people, while looking down on others, are also afraid that they are actually as stupid and weak as others.

Jiayi's description is consistent with Fang Zhenyue's understanding of Liu Xujie, so he nodded and agreed with her explanation.

"So I told him what I would do if I were the murderer. I let him know that an ordinary detective is smarter, more cautious, and more powerful than him. In this way, he will jump from a state of arrogance to the opposite extreme, feel humble, and then feel fearful and afraid. "

Jiayi nodded at Fang Zhenyue, and quickly recalled the words she had prepared in advance, and then continued:

"By the way, there is another point to overcome his defenses."

"You say." Fang Zhenyue nodded, her expression focused, as if what she was about to say was so important and profound.

"I have thought seriously about those letters that Liu Xujie's family did not send out.

"Why did Liu Xujie send some but not others?

"After reading those letters, I found that the words in those letters were rather rough. They should be letters written by him in a more casual manner. At the same time, the letter expounded his love for Gu Xiaolan, which was not only lingering, but also a little... It can be said that the expression of this love would make him look humble. "

Perhaps the letters that were not sent were all confessions of bootlickers.

"When he wrote it, it was an emotional catharsis and he thought it was nothing, but when he was ready to send it, he thought about it and felt ashamed and his self-esteem was hurt, so he did not send it.

"I threatened him that I would expose all his letters to the media, so that everyone in the world would know how humble he was.

"When he heard this, he became frightened and angry. "

Fang Zhenyue stared at her eyes and moved his lips but said nothing.

Jiayi breathed a sigh of relief and looked up to see Tannen also outside the door, holding a notebook and taking notes of what she said.

At this time, You Zhaohua came out of the small dark room and asked casually:

"Then why did you turn off the radio function and not let us listen, Eleventh Sister?"

Jiayi opened her lips to answer, but Tannen, who was standing next to her, said first:

"If someone is monitoring and eavesdropping, the murderer will always be alert and tense, and it will not be easy for him to relax and be conquered.

"I think the reason why Officer Yi had to walk into the interrogation room alone to talk to the murderer and turn off the radio system was for only one purpose -

"that is to reduce the murderer's guard.

"Am I right, Officer Yi?"

Tannen said, turning to look at Jiayi. His long eyes were slightly curved behind his glasses, and the corners of his lips were slightly raised, as if seeking praise.

Jiayi was a little embarrassed. She didn't expect that Inspector T, a real expert in being deceived, would help her deceive others.

But she still nodded and praised sincerely as he expected:

"Inspector T's answer is very professional. It is for this purpose that I turned off the sound system."

It's not that he was afraid of being heard!

You Zhaohua stood by, looking at Tannen with a look of faith, then at Yi Jiayi who looked a little shy for some reason, and finally looked at the tall Fang Zhenyue who stood shoulder to shoulder with him.

"This is a flying thousand-mile horse!" You Zhaohua approached Fang Zhenyue and whispered softly.

Fang Zhenyue tilted his head, took a step away from You Zhaohua, raised his eyebrows and nodded as a response.

"..." You Zhaohua.

This guy is so proud.

Tannen, who was standing next to Jiayi, did not pay attention to the "secret interaction" between You Zhaohua and Fang Zhenyue. He put away his notebook and pen, raised his head, and nodded to Yi Jiayi very solemnly:

"About the description of Liu Xujie's personality, targeting the criminal's weaknesses, and how to break down his psychological defenses.

"And using the unsent love letter as a breakthrough point to accurately grasp the criminal's weaknesses... It's really exciting. "

He remembered what Jiayi said to him before she walked into the interrogation room, "...your expertise will affect the verdict of a large number of cases...help the Hong Kong police force to uphold justice. Don't let a murderer go, don't wrongly accuse a good person, take this as your goal, let us encourage each other!".

Yi Jiayi is indeed doing this. She has not received professional training, but she has worked so hard and studied so deeply. He has such a good environment and a more solid foundation than her, how can he lose to her? He should work harder and be more attentive! He

stretched out his right hand towards Jiayi, and when the other party ignorantly stretched out his hand to shake his, Tannen said sincerely:

"Although I am a newcomer to the Hong Kong police force, I will learn from every hard-working Hong Kong police officer, and I will also work hard to become a competent police expert. "

Sooner or later, he will really live up to the word 'expert' and will not be ashamed of being called that by others. "

He let go of her hand, nodded to Jiayi and Fang Zhenyue again, and then left with the notebook in his hand.

Jiayi scratched her head, embarrassed by the respect in his attitude, and even dug her toes into the ground.

As a person who can see the resonance of hearts, although she will feel a strong sense of accomplishment when she defeats the murderer, and will feel happy and excited when she catches the murderer, she still feels embarrassed every time she is praised.

Looking at Tannen's back, she thought silently: Inspector T, although 'awesome' is fake, I will not let 'hard work' be mixed with a little fakeness.

Let's encourage each other. She

retracted her gaze and turned to face Fang Zhenyue's inquiring gaze.

Being stared at each other in silence like this, she couldn't help feeling a little uneasy.

Did Brother Yue realize that she was lying again?

Fang Zhenyue didn't say anything, but turned around and led her to the office of Group B. After turning into the corridor and leaving the sight of others, he suddenly stopped and turned around. When she was off guard, he stretched out his arm and rubbed her head hard.

Jiayi felt that Brother Yue's rub seemed to bring some release.

When she looked up, she seemed to see helplessness in his eyes, but it disappeared when he blinked. Was it her illusion?

Maybe there was only admiration and recognition in Brother Yue's eyes, and she was too guilty, so she felt that there were other emotions conveyed in Brother Yue's eyes?

"What is it, Brother Yue?" When Fang Zhenyue turned around and continued to walk at a brisk pace, Jiayi hurriedly caught up with him and looked up to ask him.

Turning his head and looking at her deeply, he raised his eyebrows and said, "I won't tell you."

"..." Jiayi scratched her face. What's going on? She hid it from him, so he also hid it from her?

I don't understand.

Men's hearts are as cryptic as the sea.

But she herself also hides secrets very deeply, so in this case, she is really good at lying.

I remembered that in "The Heaven Sword and Dragon Saber", Yin Susu said to her son Zhang Wuji, "The more beautiful a woman is, the more likely she is to lie." She is so good at lying, she must be a beauty, right?

Thinking of this, she pulled her lips and smiled, and when she turned into the office of Group B, she quietly hid her smile and put the self-mockery just now behind her.

After that, Brother Yue only talked about business and did not mention Jiayi's interrogation of Liu Xujie.

Jiu Shu and others had seen Yi Jiayi interrogating other murderers before, and they thought that this time was the same as other times. After returning to the office, they only praised Jiayi for her sharpness, or sighed that the case was finally solved, and did not dwell too much on the silent interrogation that had passed.

Everyone divided the work and cooperated, sorted out the case files, reconstructed the case, re-examined Liu Xujie, asked whether there were other victims besides Zhao Dongsheng and Liang Fengshi, notified Mrs. Zhao to come and pick up Zhao Dongsheng's body, held a meeting with the Public Relations Department to confirm which information could be made public, and wrote a case report...

Countless trivial tasks are still waiting for the detectives of Group B.

...

On the other hand, Tannen followed up all subsequent interrogations of Liu Xujie.

But every time the detectives asked Liu Xujie what Officer Yi Jiayi had told him, Liu Xujie always kept his lips tightly shut and refused to say a word.

If the detectives mentioned the letters that Liu Xujie had not sent, he would immediately become angry and embarrassed, and even stated that even if he was a murderer, he had human rights, and it was illegal for the police to disclose his private letters without consent.

Tannen checked in his notes, recorded these reactions of Liu Xujie, and looked for knowledge points that could explain Liu Xujie's behavior in what he had learned, which was basically consistent with what Jiayi said.

As for Liu Xujie's reluctance to recall the interrogation with Yi Jiayi, Tannen concluded that "criminal psychology shows that perverted criminals are easily influenced by the outside world and stimulated to commit crimes. What Detective Yi Jiayi said during the interrogation was exactly what stimulated Liu Xujie's self-esteem. The criminal's freedom was restricted in the police station and he could not rely on crime to vent his emotions, so he had to refuse to face and respond to all related questions."

When reviewing this case, Tannen analyzed the reasons for his profiling errors, and combined with Yi Jiayi's suggestions and theories, he wrote a very detailed and fair report and handed it to Sir Huang.

…

Sitting in Superintendent Huang’s office, Tannen reported the methods he saw the CID detectives use to solve the case during the entire investigation process, including everyone’s bravery and hard work, Fang Zhenyue’s logical reasoning ability and decision-making ability, and of course Yi Jiayi’s sharpness and decisiveness, as well as her achievements in criminal psychology and psychology.

He tried his best to appear fair, but did not praise Yi Jiayi too much. Superintendent Huang nodded and took his report sheet, and said:

"Yi Jiayi will be interviewed by the sergeant soon. As an expert inspector, you should make an evaluation report on Yi Jiayi from your field."

Tannen poked the frame of his glasses, "The kind that will be entered into her file?"

"Of course." Superintendent Huang nodded.

"OK, sir." Tannen stood up and saluted, took the task and returned to the office. Half an hour later, he had written an extra-long report and put it on Superintendent Huang's desk.

...

Superintendent Huang returned from the meeting and saw the report on the desk. He couldn't help but marvel at Tannen's amazing efficiency.

He picked up the report and read an English reading comprehension level 5 assessment report.

Inspector T mobilized all his English reserves, and used gorgeous words and generous praise to say that Yi Jiayi was a very rare local profiling genius. He even said that in his opinion, as a Hong Kong detective, Yi Jiayi's profiling of Hong Kong local criminals was not inferior to experts in related fields in the UK and the United States.

This report clearly showed Tannen's recognition and even admiration for Yi Jiayi.

Superintendent Wong read this fair assessment report and raised his eyebrows in a playful manner.

After pondering for a while, he finally wrote his reply and put it together with other files and assessment documents of Yik Ka-yee.

After finishing the work here, Superintendent Wong took two inspectors to the Central Police Station for a meeting, where he met Rick, the forensic officer of the Central Police Station. During

the chat, Rick suggested that the content sharing he would do on the forensic professional direction would be held next week, and all the detectives from West Kowloon were invited to listen.

Superintendent Wong immediately said that it was no problem and he would urge the entire police force to come and learn.

Rick thought about it and couldn't help but add: "By the way, Yik Ka-yee from CID Group B will not be absent, right?"

I wonder if Yik Ka-yee has other cases to deal with after the Zhao Dongsheng case.

Superintendent Huang was slightly stunned. He had never expected that Rick would single out Yi Jiayi. He raised his eyebrows and asked curiously:

"Why did you mention Yi Jiayi alone? Are you familiar with her?"

"In the Zhao Dongsheng case, your West Kowloon Serious Crime Unit worked together with our Central Police Station Forensic Division and Forensic Department to solve the case. Yi Jiayi came over to communicate clues, so of course I know her. We are not very familiar with each other, but it was she who asked to hear this sharing that I thought of doing it." Rick smiled and said casually.

Superintendent Huang couldn't help but savor Rick's words. These busy old experts are not the kind of people who are willing to spend time and effort to share with you just by asking.

Facing Superintendent Huang's puzzled eyes, Rick couldn't help but smile and waved his hand and said:

"Don't think too much. It's the detective Yi in your police force who has a strong thirst for knowledge.

" "At that time, she humbly asked me for advice and said that if the detectives had simple forensic knowledge, it would be of great benefit to the efficiency of investigation and the rate of solving cases. She also said that some of the little tricks I mentioned to her that day were of great help to her .

"Think about it this way, sharing is just a simple thing, but it has huge benefits for our justice cause. Isn't it very meaningful, right?"

"Very correct!" Superintendent Huang nodded in agreement. Within one day, he had met two people who were quickly conquered by Yi Jiayi, two experts in different disciplines.

Yi Jiayi, this young girl, has a very good work attitude.

She completely inspired the old expert's desire to show off... no, to share, and inspired Rick's ambition to lead everyone to progress.

Hmm... she's really good at dealing with top students like Rick and Tannen!

Tsk.
