The waiting time is always the longest, and the minute that was originally short seems to be infinitely extended at this moment.

Xiao Ning sat in a chair and looked out the window.

The rain falls on the glass surface and flows downstream, making all the scenery hazy, and the night lights distort and come into view.

He turned his gaze back to the phone in the middle of the table.

The all-black avatar must represent something.

A psychologist once said that people nowadays like to communicate with each other through social software.

Then when you don't see a real person and can't guess through the tone of speech and micro-expressions, you can use the most intuitive name and avatar on the software.

Because this can show the person's preferences to a certain extent, and you can roughly guess his psychology by peeling back the cocoon.

The all-black avatar, if it is placed on a murderer, may really be very appropriate.

What does the all-white avatar of the other side mean?

Xiao Ning doesn't like to figure out a person's psychology, because there are too many things hidden in it, whether light or darkness, too much cruelty and distortion of human nature, which are deeply buried in it.

But when it came to this, he had to do it again. Only by accurately grasping the psychology of the murderer can we roughly guess what they will do next and to what extent they will go.

Xiao Ning's eyes kept flashing the screenshot chat picture at this time, back and forth, every word was so clear.

This seemingly unremarkable photo, mixed with the smiling selfie of the deceased Deng Yujia, is like a bloody sharp dagger, symbolizing death.

He stood up suddenly and came to the corridor, "Xu Xingteng! ”

After a while, Xu Xingteng trotted out of the area on the other side, "Boss, what's wrong?" ”

"Did you find Zhang Hai's phone?"

Xu Xingteng didn't think about it, and replied directly: "No." ”

Xiao Ning took a step back and returned to his office. Also, if Zhang Hai's mobile phone is really found, it is impossible that it has not been handed over to him by now.

He had a feeling that maybe the person with the all-white head was Zhang Hai.

The bathroom he saw in his dream coincided with the bathroom in the chat log, and it was Zhang Hai's home.

After waiting for a full two hours, Xiao Ning finally waited for the news he wanted.

First of all, I learned the account of the deceased Deng Yujia through the chat software of the deceased Deng Yujia, and then found out the real identity of the real name through the background registration information.

Zhu Yixing, male, 31 years old, single, no history of marriage. His current profession is a surgeon, and he happens to be in the same municipal hospital as Zhang Hai.

Xiao Ning looked away from the document, all the information of Zhu and his party was very consistent with the murderer.

First, he was a surgeon, and those autopsy wounds on the body of the deceased after death had to have a certain medical foundation to do it, and his profession corresponded to it.

Second, he and Zhang Hai are in the same hospital, so they have a channel for acquaintance and the possibility of entanglement.

Third, he is single and has no history of marriage. According to the various criminals in the past, people who live alone tend to have a higher chance of committing crimes, because they are not bound by family and wife, children and daughters, so they are more bold and confident to do it.

Zhu and his entourage were immediately regarded as key suspects by Xiao Ning, and he looked at Xu Xingteng, "Go to the city hospital and bring Zhu and his entourage directly over." The reason is that Zhang Hai's jumping off the building is still in doubt, and he needs to cooperate with the investigation. ”

After speaking, Xiao Ning stood up, "Forget it, I'll go with you." ”

He believes more in what he sees with his eyes, and the reason why he has been able to solve so many difficult cases is not because his IQ is much higher than that of ordinary people.

It's because of his way of thinking, and his careful observation. These two points are the most important, and they are also the most overlooked.

Sitting in the car, Xiao Ning closed his eyes and pondered, only the sound of the engine sounded in his ears.

It's still raining.

The car stopped at the entrance of the municipal hospital, and Xiao Ning walked quickly into the rain. By the time he entered the building, his hair was drenched and his coat was dripping with water.

He didn't care in the slightest, didn't squeeze the elevator, and went down the stairs to the second floor.

In the consultation room, Zhu and his entourage were sitting in front of the computer, motionless.

When he heard the sound, he turned his head sideways and saw Xiao Ning coming in, and he didn't look surprised at all, as if he had expected it a long time ago.

He smiled at Xiao Ning, "Officer Xiao." ”

Xiao Ning looked at him fixedly, "You know me?" ”

Zhu Yixing nodded, "Of course, I am a good friend of Lao Zhang, and I know everything he encounters, including the things you went to find him." ”

He stood up and put his hands in front of him, "I know you're here to take me to the police station, let's go." ”

None of the scenes that were expected appeared, and Xiao Ning suddenly felt like a fist hit the cotton, and the soft was discharged.

He thought that Zhu and his entourage would either pretend not to know anything, or be a little resistant, but he never expected that he would be so cooperative.

Xiao Ning frowned slightly, "Since you are Zhang Hai's good friend, do you know that he has committed suicide by jumping off the building?" ”

Zhu and his entourage nodded, a little sadness appeared on their faces, "I had long expected such a day, and Zhang Hai himself knew it, but it was just a matter of time." It doesn't matter if you jump off a building, at least if you die, you won't accept the condemnation of your conscience every day. ”

Xu Xingteng, who was behind him, heard something and immediately asked, "Do you admit that you killed those people?" ”

Zhu Yixing suddenly smiled, "No, I never said that, as for finding the murderer, it is what you should do, not me." Do not expect to know anything from my mouth, and I will not say anything. What's more, I don't know anything. ”

After speaking, he closed his mouth tightly, took off the white coat on his body, touched it with his hand very reluctantly, and finally took a deep look, and then walked out of the consultation room.

In the corridor, when the nurses passing by saw him, they would call Dr. Zhu.

Zhu and his entourage smiled at them kindly, but did not answer, as if they were laughing at themselves: "I have been in the industry for so many years, and I have always thought that I am a qualified and good doctor. But now, I feel like I've tarnished the profession. ”

He looked back at Xiao Ning, "By the way, when Zhang Hai was dying, there should have been something left for you, right?" ”

Xiao Ning didn't hide it, "Yes, he left a note." ”

Zhu Yixing sighed, "Then how did he stay?" ”

"He swallowed the note in his stomach and found out when he dissected the corpse."

Xiao Ning saw Zhu Yixing lowering his eyes, and his tone became much lower, "Zhang Hai is still so smart. ”
