The incident of poisonous hairpins found in the dock market was considered to be thunder and raindrops. The investigation team found poisonous hairpins and conducted free physical examinations on citizens who recently came into contact with hairpins in the city. It was found that few people were infected with hepatitis A.

This physical examination consumed a lot of manpower and material resources from the hospital. Because the virulent hairs appear for a short time, even if someone is infected with hepatitis A virus, they cannot use conventional antibody tests to check for viral RNA in the blood, which is a huge price.

Ao Muyang heard Dai Zongxi's sigh and asked hesitantly: "Dai, why do I feel that you feel regretful that many virus-infected people have not been found?"

Dai Zongxi said: "How is it possible? Is there anything else? Didn't hang up the phone!"

Ao Muyang hurriedly said, "Yes, yes, there's something small. I want to ask how this matter is being investigated? Where did these virus-containing hairs come from?"

Dai Zongxi said: "I checked, don't you know? It's just that Sun Beilong's company was brought from another place. The specific ones that were brought from are still being investigated, but it must be unrelated to Sun Beilong. Now the Municipal Bureau is working hard to investigate Sun Beilong."

Ao Muyang thought for a while and asked tentatively: "So, Director Dai, do you feel that this incident is a bit weird?"

Dai Zongxi said, "Strange? I'm not a ghost catching, what's weird?"

"But I think this incident has little to do with Sun Beilong, and he may have been framed."

"Then you feel wrong. This time the physical evidence is conclusive. Mao Feng must have come out of his company's warehouse!"

When they arrived here, the opinions of both sides were not unified, so Ao Muyang hung up the phone and returned to the room.

The group looked at him, and Ao Muyang nodded and said, "There are very few virus infections found in front of him, and Xiaofei's guess is correct."

"Then check those two doctors immediately." Ao Xiaofei suddenly became excited, "One of them must have a problem."

Ao Muying said: "Just check B, A's problem is not big. As a doctor of infectious diseases, he will not risk being infected with hepatitis A to prove that the hairy hair contains hepatitis A virus."

Ao Muyang thought about it and called Su Jinnan again and asked Su Jinnan to help. He wanted to pry out the news from a doctor. Their identity might not be enough, so he had to find an official person with enough weight.

While waiting for Su Jinnan, Ao Muyang asked Song Gongming to check information about Dr. B, while others watched the video to study the owner of the barbecue stall wearing a mask.

Not long after the video was played, Ao Xiaofei said: "Note, this boss is a left-handed."

Ao Muyang did not pay attention to this point. At this time, someone reminded him that it was indeed the case. The boss used his left hand to take vegetables, apply oil and sprinkle ingredients, and hand over wine.

"Stop for a moment and see what he is stuffing into his mouth. He is constantly stuffing things into his mouth." Ao Wenchang said.

Ao Muyang had noticed it before. He enlarged the image and said, "I can't see clearly, it seems that I'm eating gum, right?"

Ao Mudong said: "No, not chewing gum, yes, this seems to be betel nut?"

"This can be checked." Ao Xiaofei's eyes shined, "You see, he vomited in the flower bed behind him. The place was an alley, very remote, and no one would clean the flower bed."

Ao Daguo said, "I'll go and see where is the address?"

Ao Muyang told him the address, and he put on his clothes and went out.

After watching the video for a while, the black dragon suddenly saluted Ao Muyang.

Ao Muyang nodded to him and said, "Do whatever you want to do, don't salute me."

The black dragon was anxious, so he pointed to the person on the video and saluted another military salute.

Ao Muyang understood what he meant: "You mean, this person has served as a soldier?"

Heilong nodded, then gestured with his hands on the person's shoulders and waist on the video.

He did not gesture and everyone was not paying attention. After paying attention, they found that the man stood up straight throughout the whole process. After no guests sat down, he also maintained a straight back.

Later, Ao Daguo called and said, "Yes, he ate betel nut, and there were a lot of chewed betel nuts in the flower bed."

"Then he basically smokes," Ao Mudong said proudly, "Add betel nut plus cigarettes, his magic power is boundless!"

Ao Xiaofei followed and said, "This may be very big. The reason why he often eats betel nut is to suppress his addiction to smoking, because it is inconvenient for him to smoke when wearing a mask."

Ao Mudong reached out and slapped his thigh and said, "What are we hesitating about? Go check it out. Go to the barbecue stall owners on the street to check it out. There must be someone who knows this person. Look, retired soldiers, left-handed, have a lot of smoking addiction and have the habit of chewing betel nuts. This is easy to check."

Ao Muyang said: "I can't find out that this person is not a real night market vendor. Do you think he is very awkward when doing barbecue? And do you think the dishes in his car are relatively simple? How could a serious barbecue vendor do business like this!"

"In addition, it has been confirmed through local surveillance videos. This person has never done business in the local area except on that day, which is not in line with the business habits of small vendors!"

They were discussing, and Su Jinnan finally arrived.

Ao Muyang and his party immediately went downstairs to meet Su Jinan. The hotel manager chased after him and asked, "Sir, check out?"

"Don't retreat!"

"well!"

Su Jinnan was dressed in military uniform and was confused and asked, "What are you looking for me?"

"Do you a favor, I'm investigating a case." Seeing Su Jinnan drive by himself, he said in his heart. Then the two got on the coast guard's jeep, and the others took a big g and taxi to the infectious disease hospital.

Dr. B's name is Chang Xuanran. He is 45 years old this year. He is an associate chief physician in the hospital. He is now single. He divorced his wife two years ago due to gambling and usury loans. Now they are raising their son in high school together.

Today is Sunday, and many doctors at the infectious disease hospital were resting, and Chang Xuanran was one of them. Song Gongming found Chang Xuanran's home address, but after they came to the door, they found that he was not at home.

It happened that an old lady from the neighbor was about to go out. When she saw them appearing at the door next door, she was startled and said to her family with her trembling lips: "Old man, don't bring Xiaohui out. That bastard Xiaochang has messed with black hair again and will come to her house!"

After hearing this, Ao Muyang's heart moved. He pulled Su Jinnan out and said, "Auntie, don't be afraid, we are not a black club, we are the people's police."

Su Jinnan muttered: "I don't belong to the police squad..."

"Look, this is my colleague's ID." Ao Muyang stepped on Su Jinnan's foot and gave Song Gongming behind him another wink.

Song Gongming saluted the old lady and showed her ID. Su Jinnan also took out the ID to show her. The old lady was relieved when she saw the bright national emblem on it.

Ao Muyang said: "Auntie, we came to Dr. Chang this time to investigate something, but he seems not at home. According to the aunt's opinion, will this Dr. Chang often provoke evil?"

The old lady sighed, "It's not often. It's much better in the past two years. In the past two years, bad people often came to the door. Alas, they beat and smashed, splashed paint and splashed chicken blood, and sent paper people to coffins. Alas, they were so scared!"
