Chang Ping rushed over without hesitation, he believed that there must be something wrong with that person, and he also believed in his eyes.

"Chang Ping, why are you going!" Li Chaonan shouted.

"Arrest someone!" Chang Pingtou replied without looking back.

"Let's go!" Zhang started to say that no one had already chased after him, and Li Chaonan also quickly chased after him.

Chang Ping ran to the crowd and swept over the faces, then pushed away the people in front of him and walked inside. He was a little anxious and quickly squeezed through the crowd.

"Chang Ping, who are you arresting?" Li Chaonan and Zhang Xingqi followed behind Chang Ping.

"I don't know!" Chang Ping was still walking quickly in the crowd, face after face crossed, and some people expressed dissatisfaction, but he didn't care about it, he just wanted to find that smiling face.

Li Chaonan and Zhang Qiqi glanced at each other, and could only suppress the doubts in their hearts and follow Chang Ping tightly.

Chang Ping's gaze swept over the face of the last person, and he quickly turned around and looked at the face he had just seen again, and sighed in disappointment.

"Who the hell is it?" Li Chaonan asked.

"Probably the murderer!" Chang Ping frowned, trying to remember that face, but only the corners of his mouth were curled, and he couldn't think of anything else.

"Do you see what you look like?" Zhang started to ask.

"I can't remember seeing so many people's faces now!" Chang Ping shook his head and smiled bitterly. "But I'll recognize that face again."

"Why do you think he's a murderer?" Li Chaonan looked at Chang Ping suspiciously.

"Well, people who study psychology are very sensitive to people's body movements and facial expressions. He was smiling when I saw that face, and it was the kind of smile that was contented. No one would smile like that in front of them! Chang Ping explained.

Zhang Qiqi and Li Chaonan listened to Chang Ping's words and began to look at the lively people, although people pointed and pointed, no one laughed, and even many people had a regretful expression.

"Let's send the phone back for identification first, if it is really that song that caused the cause of death, then this matter is more serious!" Chang Ping frowned and walked back.

What kind of person is the other person? First of all, I will definitely play the piano, secondly, I will know some psychology, and again psychologically, something must be wrong. But how did he find these people? In fact, it is very simple, just stand on the street and observe the people passing by, and as a person who has studied psychology, it is still easy to gain the trust of others.

If that smiling face is the murderer, since he ran away, it means that he must have found himself, and it seems that it is no longer feasible for him to fish this person out as bait. Looking back, Zhang Xing and Li Chaonan shook their heads, they can't either.

"What's wrong?" Li Chaonan looked at Chang Ping in surprise.

"Nothing, just thinking of something!" Chang Ping shook his head. "Are there any women in the bureau?"

"Yes, Sister Tuya!" Li Chaonan replied.

"Then let Sister Tuya be a bait and see if you can catch the murderer!" Chang Ping looked at Li Chaonan and Zhang Qiqi and said.

"How do you fish?" Zhang Xingxing asked.

"It's very simple, just pretend to be a devastated and depressed person, and walk around the street!" Chang Ping said the plan.

"Isn't there any danger?" Li Chaonan asked worriedly.

"No, he won't do it directly!" Chang Ping replied with certainty.

"Okay, then I'll go back to the bureau and arrange it!" Zhang Qiqi nodded and said. "Next, we need to go to the deceased's house and check it out!"

"It just so happens that I have a phone here, just let the boy who rented the house with him come with me!" Chang Ping said and dialed out with the phone.

The room is very tidy, unlike the average boy who lives very dirty. There were a few books on the desk, and a picture of a girl. Chang Ping picked up the photo and began to look at it, the girl in the photo was very beautiful and smiling happily. With a pair of fox eyes, it is difficult for such a girl to keep the woman's way, not that the girl doesn't want to fall in love, but there are too many temptations from the outside. The boy still has a photo of the girl, which shows the depth of affection. The three of them were looking for valuable clues in the small room, and the clean boy leaned against the door, a little distracted.

"He should have a regular life, right?" Chang Ping asked.

"Well, yes!" The clean boy nodded in return. "More regular than my life!"

"Uh-huh!" Chang Ping nodded, it seems that some useful clues can't be found. After all, the two people are not inseparable, so the deceased will not know about the contact with the murderer.

"Did you notice when he started listening to music?" Chang Ping looked at the clean boy.

"It seems like last Tuesday, and he came back that day with headphones." The clean boy frowned and recalled. "By the way, he asked me if I listened? I listened to piano music for a while, and I didn't like this kind of music anymore! ”

"It's okay, you refused!" Li Chaonan glanced at the boy happily.

"Do you know where he went on Tuesday?" Chang Ping continued to ask.

"I don't know, he said that he was in a bad mood and wanted to go out for a walk, I was afraid that something would happen to him and wanted to accompany him, but he directly refused!" Quickly the boy shook his head.

"Do you know where he's going to be in the last few days?" Chang Ping asked again.

"Well, you know, it's a park not far from here, out of the community and going west!" The clean boy snapped his finger.

"Okay, I'll take a look, you guys look for clues here first!" Chang Ping looked at Zhang Qiqi and Li Chaonan.

"Shall I go with you?" Li Chaonan said.

"That's it, let Superman go with you, I'll just find it here myself!" Zhang Qiqi echoed.

"Alright then!" Chang Ping hesitated and nodded. Then he went out with Li Chaonan.

If I were a boy, I would be very depressed, my girlfriend broke up with me, and I kept calling and harassing me to collect debts, which can be said to be all about discouragement, even if I didn't have that music, the idea of suicide was already very strong. I would look at the world and watch the people coming and going on the streets. I feel so sad in my heart, why is this happening to me? I am very envious of these people with smiles on their faces, but I can only envy, I also want to live a carefree life, I also want to go shopping with my beloved, so much more. Walking and stopping all the way to the park, I felt physically and mentally exhausted, so I found a bench to sit down, and I wanted to sit quietly, without noise or noise, maybe it would be good to die like this!

At this time, a person suddenly walked over, also sitting on the bench and looking at the same scenery as the boy, but kept a safe distance from the boy, and this distance would not make the boy wary and disgusted.

"Hey!" The visitor suddenly sighed heavily......
