The dilapidated living room is even more cluttered due to the disorderly stacking of countless paper documents. Pen, fun, and www.biquge.info

But Xiao Zihan seemed to be unconscious, and still efficiently sorted all kinds of documents from the pile of papers that had been completely mixed together.

When the documents on the ground were neatly organized, Xiao Zihan took out a stack of color photos from his jacket pocket......

He first picked out a portrait of Yi Siyue from the photo before her death and placed it in front of the first stack of documents on the left-hand side.

[Yi Siyue, 33 years old. He holds a Ph.D. in psychology from Tiandu University and is currently working as a psychotherapist at Tiandu Academy of Sciences. He has published a number of psychology books in his spare time, which are extremely popular. 】

Xiao Zihan took out an A2-sized piece of white paper and spread it on the ground, wrote down Yi Siyue's brief information in the center of the white paper, and framed it with a circle. At the end, he glanced at Yi Siyue's photo again, pondered for a while, and wrote the words "beautiful", "single", "intellectual", and "bereaved father" on the white paper, before nodding with satisfaction.

Then, he took out a photo of a middle-aged and elderly man with a square and calm appearance and placed it next to the second stack of papers.

[Wang Changming, 54 years old. Dean of the School of Physics, Tiandu University, Dean of the Tiandu Academy of Sciences. The absolute authority in the field of anti-gravity is the leader in the frontier field of science and technology today. 】

He drew a brief message about Wang Changming on the left side of the white paper, and marked it with "widowed", "having a son", "fame", and "power".

But in the next step, Xiao Zihan did not directly start recording the basic information of the third person, but took out a red signature pen and connected the keyword "widowed" of Wang Changming and the words "single" and "beautiful" of Yi Siyue with a red line, and connected the circle of Yi Siyue's body with the keyword of Wang Changming's "fame".

After doing these things, he pulled out a photo of an old man with gray hair.

[Li Mingduan, 66 years old.] Vice Dean of the Academy of Sciences, Tiandu University. The main direction of scientific research is physical materials science, and Tiandu is a master of physics, but compared with his influence, he is slightly inferior to Wang Changming. 】

In the same way, Xiao Zihan wrote keywords such as "old age" and "green leaves" after Li Mingduan's text message.

And this time, he did not find a specific connection between Yi Siyue and the vice president of the Academy of Sciences, but connected a lot of red lines between him and Wang Changming.

Subsequently, he pulled out a photo of a man in his forties.

[Duan Zexin, 42 years old. He holds a Ph.D. in physics from Tiandu University and is currently a senior academician of Tiandu Academy of Sciences. He served as the chief assistant to Vice President Li Mingrui. 】

"The family is happy, the work is smooth, and Yi Siyue almost only intersects at work...... It's a distraction no matter how you look at it. Xiao Zihan looked at the specific information of Duan Zexin, and muttered to himself: "However, it is not ruled out that there is a secret connection that I don't know......"

After thinking for a while, Xiao Zihan shook his head and wrote Duan Zexin's brief message on a blank piece of paper, but only connected it with Li Mingduan with a red line, and put it aside.

"It's time for the main event." Xiao Zihan took out a photo of a young man at this time, although the man didn't look very old, but the eyes that looked down on the world made people involuntarily raise his age estimate by a few years.

[Ye Chang, 33 years old. Ph.D. in Physics and Computer Science from Tiandu University. He is currently a senior academician of Tiandu Academy of Sciences. Wang Changming's proud protégé. Despite his young qualifications, he is already one of the authorities in the field of gravity. 】

Xiao Zihan did not directly write various keywords to this Ye Chang this time.

Instead, he carefully studied his resume and the information gathered from other sources, and thought about it for a long time.

"This Ye Chang is the same age as the deceased Yi Siyue, and the two are university alumni...... And the resume shows that these two people actually went to the same high school......"

"Could they have known each other for a long time?"

Thinking of this, Xiao Zihan connected the two with a red signature pen, and wrote the text "suspected childhood sweetheart" on the red line.

But these two people don't usually have much intersection, and to outsiders, they seem to be just ordinary friends...... This is not a normal thing among old classmates and colleagues who have known each other for more than ten years. ”

Brush -

There is another red line between the two people, which reads "Underground couple? "Unrequited love?" and other keywords with question marks.

Zhuo Lan, 58 years old. Mother of Yi Siyue......"

After that, Xiao Zihan wrote down several characters related to the case on a blank piece of paper, and drew their network of relationships and possible hidden relationships through various red lines and signs.

"Next is the analysis of the motive for the killing......"

He changed the pen in his hand to a black signature pen and wrote in bold handwriting the words "motive for killing".

"Then there's the direction of investigation......"

"The scene of the crime was cordoned off by the police, so I won't consider it for the time being."

"The work place of the Tiandu Academy of Sciences is a semi-military restricted area, and it is difficult for private detectives to enter and put it on hold."

"Yi Siyue's mother is a breakthrough......

Xiao Zihan narrowed his eyes, and his knuckles kept tapping on the floor of the living room......

Tuk-tuk-tuk-tuk-

Wait a minute......

He seemed to suddenly think of something, and his eyes lit up, whether it was the dead or the suspect, they all had a place that they couldn't avoid......

Tiandu University!

……

"At present, it seems that the only breakthrough point we can find is Yi Siyue's mother, Zhuo Lan."

Lin Peijun sorted out a large pile of materials on the desk and said to Lu Xifa, who was sitting on the side of the computer.

Lu Xifa got up and took the document that Lin Peiyun put on the top, and frowned: "As reporters, our authority is still too small, and we will definitely not be able to enter the scene of the crime, and other villas in Wenyue Community must also apply in advance...... The only people I can find now are those relatives and friends who have a relationship with Yi Siyue. ”

After that, he looked at the watch on his wrist: "It's not early, let's get up early tomorrow to interview Yi Siyue's family and acquaintances." ”

……

"If my cousin were here, where would he start investigating?" Gu Fan's whole body sank into the sofa, his hands resting on the back of his head, staring at the ceiling above the police lounge a little bored, as if talking to himself.

The leaf worm on the side had already been overwhelmed by the mountain of information, and couldn't help but suffocate when he heard the words, and said angrily: "You have the time to think about this, why don't you come and help me classify the documents." ”

"Those things don't mean much." Gu Fan glanced at the documents on the desk, pouted, and said, "If you really want to reveal the truth, tomorrow's interrogation of several suspects is the main thing......

"This method of extracting key clues from countless pieces of junk information...... Without a strong memory and logical analysis ability, it is difficult to move an inch. ”

"Thanks to our identity as a task force policeman...... If you were assigned the identity of a private detective at the beginning, I am afraid that you would really have to use this stupid method to investigate the case. ”

No longer paying attention to the small leaf worm that looked at the documents on the side, Gu Fan continued to stare at the ceiling above his head, muttering to himself:

"If my cousin is here......"
