Captain Liu knew that his subordinates were eager to solve the case, but he also had to rest.

"Go back and rest, the bureau has its own arrangements! Also, Xu Sanshao's improper business and murder were all passed on by those gangsters in the Qin Long Gang, and you can't talk nonsense without evidence, what is the identity of the Xu family, beware of getting into trouble! ”

He kindly reminded his subordinates that to solve a case, we must talk about evidence, and we can't just listen to one side of the story.

Xu Yi only abolished Qin Yonghuai's hand two days ago, and he died not long after, the people of the Qin Long Gang must think that they can't get rid of Xu Yi, and it is not impossible to spread rumors against Xu Yi.

Hearing his reprimand, the police officers collectively stopped talking, and Captain Liu waved his hand and signaled everyone to disperse.

Although everyone was unwilling, they still obeyed the order and left the police station one after another......

Soon after they left, as Captain Lau said, the bureau arranged for a mysterious guest, who was a specially appointed negotiator of the Regional Police Department, and was directly invited to the interrogation center of the Serious Crime Unit.

In the monitoring room, Captain Liu warmly received him-

"Welcome, welcome, I didn't expect Professor Lu to be so young and admired his name for a long time, I will be fortunate to meet him." He wanted to shake hands with the guest, but the other party didn't stretch out his hand, so he had to withdraw his hand in embarrassment.

"Professor Lu, it's really ...... to invite you so late"

"Don't say kind words." The other party's tone was cold, he only glanced at him, and then stared at Xu Yi on the other side of the room through the glass window, "He is Xu Sanshao?" ”

Sure enough, as rumored, he was heroic and imposing.

"Yes, Professor Deer, you ......"

Captain Liu still wanted to speak, but at this time, the other party had already turned around and went out to the interrogation room.

"Turn off all CCTV." Before entering the door, he confessed.

Captain Liu did not hesitate and immediately did so, knowing the rules of this Professor Deer.

When he interrogates prisoners, he must turn off all surveillance, including the other side of the surveillance room.

This was a special request to become a police negotiator, and the police also expressed their understanding, because top experts like him naturally have their own set of methods, and they will not spread the word, and turn off the surveillance in order to avoid revealing their negotiation skills.

"You pay attention to safety......" Captain Liu sent him to the door and repeatedly told him to be careful......

Interrogation room.

Xu Yi sat on the chair and closed his eyes, heard movement at the door, and suddenly opened his eyes, staring at the door with dark eyes.

A young man walked in from the outside, he was dressed in a black suit, very formal, tall and straight, with a tough face, no more than twenty-five or sixteen years old.

The man wears gold-rimmed glasses, elegant and elegant, his eyebrows are raised, and there is a sharp edge in his warm smile, which is difficult to ignore.

At first sight, Xu Yi was wary, but she didn't sit upright, and squinted at him in a scrutinizing posture, trying to see through him.

"Xu Sanshao, hello." The man was polite, using honorifics, and held out his hand across an interrogation table.

Xu Yi didn't move, squinted, staring at the pair of fair-skinned and good-looking hands, with her experience, a man with such beautiful hands was either a doctor or a scholar.

Seeing that she was silent, the man smiled, withdrew his hand with a complacent demeanor, and sat down across from her.

"Introduce yourself first...... he put away his briefcase and greeted her with a smile, "Lu Nan, professor of the Department of Medicine of Heguo First University. ”

Professor?

Xu Yi raised his eyebrows, his eyes were full of inquiry, and he said that he was a professor She believed it, but what did the professor of medicine do when he came to the interrogation room? Ready to give her a drug to extract a confession!?

"Huh." As if to see her suspicions, the man smiled and said, "At the same time, I am also a negotiation adviser to the police. ”
