Madam Yi Jiayi and her junior master Xu Shaowei rode the bus back to Yau Ma Tei Police Station.

As soon as they entered the office, they happened to see Tannen and Fang Zhenyue having a disagreement.

"Sir Fang, there are many suspects in this case and the search area is very wide. This is a good opportunity to verify the usefulness of criminal psychology in solving criminal cases--" Inspector T was trying his best to instill his own ideas and knowledge into Fang Zhenyue, arguing with reason. Although he had heavy dark circles under his eyes, he still looked very energetic when he spoke in a rhythmic manner.

"Criminal investigation solves cases to reveal the truth to the world, to punish evil and promote good, not to verify a certain scientific method." Fang Zhenyue stood by the whiteboard, and although he frowned slightly, he did not look impatient, only a little tiredness was revealed between his eyebrows.

"That's not what I meant..." Tannen admitted that he had said the wrong thing and apologized hurriedly. However, such a small setback could not dampen his enthusiasm at all, and he still insisted on speaking.

He needed more autonomy and more cooperation.

Except for Brother Sanfu and Gary who were waiting in Jinshan, the other detectives from Group B were all there, plus Tony and a senior sister from Group A who were brought by Inspector T yesterday.

Everyone was sitting in the office, watching the two superiors discuss the next policy and strategy with numb faces. They were tired, but they didn't dare to take a nap at the desk. They were very embarrassed.

Jiayi didn't know whether she was irritated by the atmosphere, or because she suddenly walked into the warm office from the cold outdoors. The warmth in the room rushed into her chest, and an inexplicable itching rolled in her throat. As soon as she walked into the door, she burst into an unstoppable cough.

It was not intentional, but he still interrupted Tannen's words, causing him to turn his head somewhat powerlessly, looking at Jiayi with eyes that were not sure whether they were resentful or helpless. Jiayi

ignored everything else and went straight to the water on the office table.

Uncle Jiu had already walked to the office table, picked up the ginger tea that Sun Xin had reminded him to keep warm when he delivered the takeaway in the morning, and stuffed it into Jiayi's hand.

Jiayi gulped down half a cup of warm ginger tea, and only then did she feel that her chest was no longer churning and her throat was no longer itchy.

Turning her head, she saw that everyone was looking at her, including Tannen, so she smiled embarrassedly and said in a hoarse voice:

"Inspector T, please continue. Sorry, I caught a cold."

Then she picked up another cup of ginger tea from the office table and handed it to Inspector T as a gesture of goodwill.

Tannen had been on guard all night last night. Although he had a chance to take a nap, he still felt uncomfortable sitting in the car

. He had been working so hard until today but had no results. He was in a bad mood. Although he still had reason, he knew that he could not think that the detectives of Team B were deliberately making trouble just because his work was not going well, which led to his failure to fire the first shot after returning to Hong Kong and joining the police force.

He took a deep breath, accepted the ginger tea that Yi Jiayi offered him kindly, and was about to continue to argue, but he saw Fang Zhenyue turned around and paid attention to other things.

Fang Zhenyue walked to Yi Jiayi, touched her forehead with the back of his hand, and then touched his own forehead. After confirming that the female police officer did not have a fever, he said:

"Don't take off your coat so quickly after entering the room. Put on your coat, sit there and drink ginger tea and hot water, and sweat it out."

"Yes, sir." Jiayi responded immediately and was about to get her coat.

Liu Jiaming had already gone to the clothes rack and handed her the coat.

Jiayi was about to pour hot water again. Xu Shaowei happened to be standing by the water dispenser, so he poured her a large cup of hot water and walked over to put it on the table next to her.

Jiayi said thank you.

Tannen watched these people coming and going around Yi Jiayi. His heart was originally full of depression and irritability, but he was inexplicably attracted by a certain atmosphere.

After exhaling a breath of foul air, he actually became a little more patient. He stood in front of the whiteboard and quietly watched the agents working, thinking calmly.

What Tannen wanted to advocate today was to overturn all the current reasoning of Team B. It was not that he completely disagreed with the work results of Team B, but he just wanted to introduce his ideas and then make another deduction.

For example, now everyone's search direction is completely focused on the stalker next to Gu Xiaolan, but in fact, there is no evidence to prove that the stalker is the murderer of the Zhao Dongsheng case. Everything is just the only assumption in the absence of other clues.

But if he, an external expert, is introduced, and the advanced science of criminal psychology is introduced, and all the clues are sorted out from the beginning, there may be a new direction.

Maybe all the current difficulties are caused by everyone missing some important clues, important reasoning, and important profiling information, which led to taking the wrong path?

But now the agents of Group B are too busy and too hard-working. They simply cannot spare the time, and they cannot allocate enough manpower.

Cooperation is too difficult, and coordination and communication are even more difficult.

Pinching his eyebrows, he suddenly reached into his bag, grabbed a handful, and took out a glasses case.

Because he didn't want to leave a nerd impression on everyone, he had been hiding his glasses and not wearing them. Now he can't care about these anymore, so he simply pinched out a frameless pair of glasses, put them on, and sighed.

The agents of Group B looked at his expression and movements, and seemed to have noticed the helplessness and embarrassment of Inspector T in the stalemate.

When Tannen sighed about wearing glasses, the detectives sighed unconsciously as well.

Uncle Jiu walked past Tannen and went to the window to close the wide-open window.

The weather has been getting warmer recently, and the windows in the office are open for ventilation. Everyone has been running around outside these two days, and it’s cold and dewy at night, so it’s better to have less wind.

Jiayi finally recovered her breath, and turned around and asked Uncle Jiu quietly: "Uncle Jiu, do you have my fax?"

"Yes, I just read it. Did you send the stalker's love letter to the handwriting identification department?" Uncle Jiu took out a copy from a pile of documents beside the desk and handed it to Yi Jiayi.

When Jiayi lowered her head to read, Uncle Jiu came over and pointed to some contents written in the document and said, "I have used this before. Why are you checking it?" "

Ah? Uncle Jiu used it before? I want to know the information of the stalker based on this. I found these words he wrote..." Jiayi hurried to Uncle Jiu and asked in a low voice.

Uncle Jiu then talked to her head like a father and daughter.

At this time, the door of Qiu Susan's office opposite the B group office opened. Madam raised her head and strode to the door of the B group office. She looked around and doubts arose in her eyes, as if asking: What are you doing? Why is the atmosphere so depressing?

Everyone looked up at her, and no one explained the current situation to her. They only used their eyes to convey their expectations: I hope she can bring good news.

Madam really lived up to everyone's expectations:

"Gu Xiaolan agreed that we can go to her house for investigation. The Central Police Station Forensic Division has been dispatched. Let's go too."

Fang Zhenyue glanced at the time, and Qiu Sushan immediately understood and said:

"After Sanfu and Gary finish their stakeout at Jinshan, I will arrange two people to take over from them. You can go to Gu Xiaolan's house without any worries."

"Thanks, madam." Fang Zhenyue nodded.

Qiu Susan patted him on the shoulder, then turned back to the office to arrange the personnel and deployments that would be needed for all subsequent stakeout tasks.

Fang Zhenyue turned around and waved to the agents to signal everyone to go out to Gu Xiaolan's house together. When he reached the door, he turned to look at Tannen, who was still standing by the whiteboard with an awkward and nervous expression.

"Come along, Inspector T?" Fang Zhenyue asked.

Tannen probably never expected Fang Zhenyue to take the initiative to call him. When he heard the other party's call, he raised his eyes and looked at him in shock, his eyes blank and even helpless.

Responding to Fang Zhenyue's meaning, Tannen's muscles around his mouth and eyebrows instantly rose. His emotions were overwhelming, his ears were hot and his face was red. He almost saluted Fang Zhenyue, a sergeant of a lower level than himself, because of the feeling of being recognized and accepted.

"Okay." Tannen took a breath to suppress his emotions, and nodded to Fang Zhenyue with a solemn expression.
