The next morning, Zhan Zhao and the yawning Bai Yutang walked into the police station gate together.

"By the way, why did you sleep on the ground last night?" Zhan Zhao asked Bai Yutang in confusion.

Bai Yutang is so angry...

As soon as I walked into the door, I met Zhang Long, Wang Chao and Ma Han who were walking with a lot of information.

"Head!" Zhang Long looked up and saw Bai Yutang and Zhan Zhao.

"How is it?" The two took some of the information they had, and everyone walked towards the elevator together.

"Huh..." Zhang Long shook his head, "There are a lot of information, and the victims are different. It seems that there is nothing special about it after looking at it, but I have brought all the information back and I am going to chew it for another two days.

"Dao, have any documents found in Wu Hao's family?" Zhan Zhao asked.

"Ha..." Wang Chao said with a wry smile, "It's evil. When we reach that time, we just happen to encounter a fire truck putting out the fire!"

"What?" Zhan Zhao and Bai Yutang were shocked at the same time, "Wu Hao's house is on fire?"

"That's right, it took half an hour to finish it. We went in and looked at it. It was all the paper burned."

"You mean you only burned paper?" Bai Yutang asked.

"After seeing the scene, the experts in the arson department said that it was obvious that they were deliberately setting fire! And the main targets were bookshelf, cabinet, desk and other places for putting paper." Wang Chao shrugged, "Later we checked it again and found some pieces of paper and some... paper ash..." As he said that, he looked at a cardboard box in his hand for Zhan Zhao and Bai Yutang, "This is a gift to Jiang Ping."

Bai Yutang and Zhan Zhao looked at each other and smiled: "These are enough puzzles that Jiang Ping has played with for the afternoon."

After leaving the elevator, quickly walked towards the office of S.C.I.

"Where has Zhao Hu gone?" Bai Yutang looked at the shadow of Zhao Hu in the office, "How is the black Honda I asked him to check?"

"It's been found out, it's a car lost." Jiang Ping, who was buried in front of the computer, raised his head, "Just just now, my colleague from the transportation department called, and he went down to get the information..."

The office door was pushed open, and Gongsun, who had a gloomy face, walked in.

Zhan Zhao and Bai Yutang saw his face and knew that he must have been in the anatomy room for a whole night last night.

"How is it?" Bai Yutang asked while handing him the coffee he had not had time to drink.

"Ha..." Gongsun sneered, took the coffee and said, "This guy is a completely pervert!!" As he said that, he handed the thick autopsy report in his hand to Bai Yutang.

"Brothers! Have a meeting." Bai Yutang called everyone to the conference room.

Gongsun Xian explained the cause of Wu Hao's death: "The preliminary examination in prison yesterday was poisoning because his heart stopped working under abnormal conditions. However, I did not find any poison in his stomach and blood, but I found something else."

Gongsun paused and said, "□□"

…?… Bai Yutang was stunned, what was it?

"Duerenic." Zhan Zhao suddenly frowned and looked at Gongsun and said, "Its effect and mechanism on the human body are similar to morphine, but its analgesic effect is small, which is only 1/10--1/8 of morphine. This is a strictly controlled anesthetic drug."

Gongsun nodded.

"Drugs?" Bai Yutang looked at Gongsun, "Wu Hao has no history of drug use, and the effect of Du Leng Ding is relatively mild. How could it cause his death?"

Gongsun continued to nod: "That's why I said this guy is perverted." Then, he took out another photo and placed it in front of everyone: "This is the left chest of the corpse, the heart part, look!"

Everyone leaned over and looked carefully, and saw a very small red dot directly above the left chest of the corpse.

"What is this?" Zhang Long was puzzled.

"A pinhole." Gongsun replied.

"I understand..." Bai Yutang looked at Zhan Zhao, "Maoer, do you remember that crazy No. 2 said, the doctor was holding a needle in his hand?"

Zhan Zhao nodded, Bai Yutang continued to ask Gongsun: "The murderer inserted the needle directly into Wu Hao's heart and injected Du Lengding there, right?"

Gongsun pushed his glasses with his index finger and said, "Yes! As long as one needle is placed, people will die of heart failure within five minutes."

After a glance at each other, everyone's faces were filled with surprise.

Zhan Zhao picked up the photo: "This person may be really a doctor."

"I think so too." Gongsun agreed, "Even if he is not a doctor, his profession should be able to access this regulated anesthetic. And judging from the position and method of the needle, he must have received professional training."

At this time, the door of the conference room was pushed open, and Zhao Hu hurriedly ran in, "Head, the report is brought."

As he said that, he handed a report to Bai Yutang.

Bai Yutang opened it and saw that it was a registration sign for losing his car. After looking down for a while, his face suddenly became serious.

"What's wrong? Is there something wrong with this car?" Zhan Zhao hurriedly asked when he saw Bai Yutang's face was not good.

"There is no problem with the car." Bai Yutang shook his head and said, "It's just that the car was stolen is a bit subtle."

…?…

"Subtle? What does it mean?" Zhan Zhao looked at him in confusion.

Bai Yutang turned his face and stared at Zhan Zhao, saying in a rare and serious tone: "At the north gate of University C."

…!…

"Maoer, I remember you go to C University every week to teach a class for students in the psychology department, right?"

"..." Zhan Zhao nodded, "The north gate is facing the building of the Department of Psychology..."

Bai Yutang closed the report and was a little worried, "The lost car in your class place, I kept track of you yesterday, and I wanted to hit you last night."
