"I just ran to the sixth floor, and I didn't see any people, so I looked down from the side of the corridor, and then I saw this guy." Li Weiguo pointed at Du Zhiqiang and explained, "Then I ran down in a hurry." ”

"Didn't this guy come down from the sixth floor?" Wen Yiqian raised his eyebrows slightly, raised his head and looked at the residential building.

At this time, the residents who had already heard the noise came out of the room, and were lying on the railing of the corridor, watching the show and talking about it.

"You mean, the murderer wasn't him?" Li Weiguo frowned, "Did you see the murderer on the sixth floor just now?" ”

Wen Yiqian shrugged his shoulders noncommittally.

"I'll go up and have a look." Li Weiguo thought for a while.

If you want to catch criminals, the sooner you can, the better.

Once the other party calmed down, cleared the traces of the crime, the evidence, and went into hiding.

Whether it is to find or capture, the difficulty will be greatly increased.

The first time the crime occurs, it must be the time when the criminal has the most flaws, and it is also the time when it is easiest to arrest.

Except, of course, for certain well-orchestrated murders.

Even if Li Weiguo is a policeman, he will not be handcuffed at any time, not to mention that he is on vacation today.

He only took out the belt and tied Du Zhiqiang under him with the belt to tie his hands behind him.

"You watch him, okay?" Li Weiguo looked at Wen Yiqian with some concern.

"Am I such a waste in your heart?" Wen Yiqian rolled his eyes, "Don't worry, I'm not even unable to look at myself." ”

"If you're okay, can you take care of it too?" Li Weiguo was still a little uneasy, and said to the resident.

In the face of the police's request, the resident was still very talkative, and nodded honestly.

"Then be careful." Li Weiguo instructed, walked towards the residential building without looking back, and soon disappeared from sight.

The seven-storey building is a semi-open setting like a school building.

On one side of the corridor is the room, and on the other side is a railing more than a meter high.

The floor is quite old, there is no elevator, you can only climb the stairs.

The walls next to the stairs are covered with various children's graffiti, which looks full of life.

Li Weiguo walked quickly to the corridor on the sixth floor.

He glanced to the left and right, and there was no one.

Came to the stone railing and looked down.

Wen Yiqian had already pulled the mentally abnormal Du Zhiqiang and walked to the side of the flower bed to sit down and rest.

Li Weiguo shook his head, but he didn't care.

He glanced at the girl's position and found a place on the stone railing.

On the railing, there is no trace left.

Corresponding to this position is a closed door.

Li Weiguo came to the door and knocked hard.

"Anyone? The police! He shouted inside.

……

Wen Yiqian sat on the edge of the flower bed and rested.

Du Zhiqiang, who was tied with his hands tied, squatted on the ground next to him, and his eyes never took off the girl's corpse.

The resident, after thinking about it, sat next to Wen Yiqian.

He habitually took out the cigarette case, took out a cigarette, held it in his mouth, and then handed the cigarette case to Wen Yiqian.

"Smoking is bad for your health." Wen Yiqian said lightly.

"I'm in good health, I'm not afraid." The occupant smiled, took back his cigarette case, took out his lighter, and was about to light a cigarette.

"I'm talking about harming my health." Wen Yiqian said with a serious face.

The resident was stunned, looked helpless, shook his head with a smile, and stuffed the cigarette in his mouth back into the cigarette case.

"You've just been a police officer for a short time, haven't you?" He asked nonchalantly as he slipped the cigarette case into his pocket.

"Why do you say that?" Wen Yiqian glanced at the other party.

It was a middle-aged man with glasses and curly hair.

"It can be seen from the performance of the policeman just now that he is not very comfortable with you." The resident smiled and said, "What's more, you're still so young." ”

"He's not worried about me...... Wen Yiqian pouted, "He's just afraid that I deliberately let this guy go, so he told you to keep an eye on me." ”

"It's a joke." The occupant smiled, not paying attention.

"I'm not a cop." Wen Yiqian said as usual.

"And what else can you be?" Residents were unimpressed.

"There is another kind of person who stays with the police besides the police." Wen Yiqian said unhurriedly.

"Criminals? Suspect? The occupants reacted immediately, their eyes widening slightly.

Wen Yiqian didn't speak, a weird smile appeared on his face, and he glanced at the other party.

The occupants didn't know what to say for a moment, and fell silent.

"A lot of criminals, they always like to come close to the crime scene again after committing a crime." Wen Yiqian said with a flat expression, as if he was stating a fact, not an inference.

"Why?" The occupants looked puzzled.

"Because it's exciting enough." Wen Yiqian said slowly, "Many perverts can't refuse this kind of excitement that is enough to make people crazy. ”

He paused, "Of course, there are also some criminals who are trying to confirm whether there is any omission in the process of committing the crime.

If they could, they would even like to know what the police think about the case to confirm the possibility of their exposure. ”

Speaking of this, he turned his head to look at the other party, "Which one are you?" ”

"Hehe...... the resident laughed dryly, "what are you kidding?" How could I be a criminal?

If I were a criminal, why would I take the initiative to ......?"

Speaking of this, he was slightly stunned and did not continue.

He originally wanted to say "why did you take the initiative to appear in front of the police", but it seemed that Wen Yiqian had already finished the answer to this question in advance.

"You don't even know what my name is, who I am, why do you say I'm a criminal?" The resident thought for a moment and said, "It's only been a few minutes since the two of us met.

How dare you be so sure that I'm a criminal based on a formulaic theory? ”

He smiled sarcastically, "Even if you do a math problem, you can't get the right answer every time you set a formula, brother!" ”

"Regardless of whether the formula can come up with the correct answer, you have to look at it first." Wen Yiqian smiled disappreciatively.

"Then you're too good." The resident's tone was a little weird, "Even the most powerful detective in the world can't be like you at a glance, and you can determine who the criminal is with a formula, right?" ”

"Maybe I'm better than the best detective in the world?" Wen Yiqian asked solemnly.

"Huh." The occupant sneered, seemingly unwilling to pay any more attention to the neurotic.

"You still don't get it?" Wen Yiqian said unhurriedly, "Why did I deliberately push that policeman away and tell you this again?" ”

He looked at the other party with a puzzled look on his face, and smiled brightly, "Because...... I didn't even want to arrest you! ”
