In the evening of the same day, it was time to get off work.

Nan Hanfei drove the car and parked at the gate of the Municipal Center for Disease Control and Prevention.

When Gu Yanan went out of work, he saw Nan Hanfei leaning against the car door, holding a rose in his hand.

Nan Hanfei walked towards Gu Yanan with a smile and gave the flowers in his hand, "Flowers with beauties, happy off work!" ”

At the gate of the CDC, there were people who were getting off work one after another, and Gu Qingcen also saw this scene, the crowd whispered, and Gu Qingcen left alone.

"What are you doing here? Are you looking for me on a business with me? ”

"Get in the car and get down to business."

Gu Yanan sat in the passenger seat, and Nan Hanfei handed her a sandwich before driving.

"Beef sandwich, I made it myself, this is the dinner I'm going to treat you to tonight."

Gu Yanan was puzzled by Nan Hanfei's series of actions, "You made such a formal invitation, calling and sending flowers, just to invite me to a sandwich?" Tell me, what exactly is the matter? ”

"My Yanan is smart, the previous ones were all smoke bombs, and the next place to go is today's destination."

——

More than 50 minutes later, Nan Hanfei parked his car in front of a factory in the suburbs.

The large black iron door of the factory has been rusted, and the black is yellow with rust.

"Get out of the car and come with me, there's something in the factory to show you this time."

Nan Hanfei took Gu Yanan around and walked to the door of a workshop in the factory.

The door of the workshop was blocked with a warning tape, and Nan Hanfei picked up the warning tape and entered the workshop.

There are many bottles and cans in the workshop, which looks like a simple chemistry laboratory, but the experimental equipment is very messy, as if the staff left in a hurry before they had time to clean up.

"Where is this?"

"Remember the last time I told you that someone reported that we had bioterrorism activities in Lianhai City?"

"Remember, you said at the time that because there was no evidence in this case, it had been closed as a hoax, and you suddenly brought me here today, did you have any new clues?"

"Yes, when I found a blonde hair in this laboratory, I didn't find a match in the public security DNA database after comparison.

However, a few days ago, someone reported that a male corpse was found in the Burning Incense River in Guanyun County, and the police investigation found that the deceased was also golden hair.

After our police investigation in the past few days, we have not found any identity information of the blonde deceased.

The murderer's modus operandi was clean and clean, leaving no useful information, and the clues were broken again. ”

Gu Yanan was shocked!

An oolong case that was characterized as a hoax, and new evidence and clues have appeared at this time, which shows that there are really bioterrorists in Lianhai City, who is this blonde man who has his throat cut? Who was the anonymous whistleblower in the first place?

Gu Yanan listened silently as Nan Hanfei finished the whole thing, "With the evidence of the blonde man, it means that someone reported that this bioterrorist organization really exists before, and the whistleblower, have you checked it?" ”

"I checked, but there were no clues."

The two clues of the blonde man and the original whistleblower have been broken, and it is not easy to find out what happened.

Gu Yanan revisited the abandoned factory floor, where most of the bottles and cans were used for bacterial and viral culture.

If the former users of this place are indeed bioterrorists, then they are using the utensils here to produce viruses and bacteria that can be used as biological weapons.

Gu Yanan approached the utensils, and he could still smell a residual smell of disinfectant.

Before being abandoned, it was disinfected with a strong oxidant to destroy all traces of pathogens.

"It's been handled very cleanly, they must have gotten inside information or knew someone reported it before they retreated, so they destroyed the evidence, but since it was disinfected, what happened to the yellow hair you found by the police?" Gu Yanan analysis.

"The yellow hair was found during our second site survey, and we thought it was someone who had broken in by mistake after our first investigation, but after this DNA comparison, I seriously suspect that the blonde deceased was probably a member of a terrorist organization."

"He may also have been the original whistleblower, who was killed by people from a terrorist organization because the news was leaked." Gu Yanan voiced her speculation.

"There is also such a possibility, but no matter who the blonde deceased is, it is certain that we have terrorist organization activities in Lianhai City."

Gu Yanan clenched his fists, "This feels very bad, it's like a sword hanging over your head and a mine under your feet." ”

Nan Hanfei pulled Gu Yanan out of the workshop, breathing in the fresh air outside the workshop in the evening.

On a summer evening, the afterglow of the setting sun reflects the entire abandoned factory in a pale red.

Gu Yanan turned his head and asked Nan Hanfei beside him, "The blonde man's case is not over yet, is it okay for you to tell me the case?" Will it violate your Force's confidentiality principles? ”

"No, it won't."

Nan Hanfei stretched out his hand towards Gu Yanan, "I now formally invite you as an external expert in this case in my personal capacity to assist our police in investigating the activities of a bioterrorist organization. ”

Nan Hanfei said it very formally, but he used "in a private name" again.

Gu Yanan knows what Nan Hanfei means, she is in the Center for Disease Control and Prevention, and she is on the first line of disease prevention.

Gu Yanan also stretched out his hand and shook it with Nan Hanfei's hand.

"Okay, I'll accept your invitation."

——

8:30 p.m. on the same day.

In front of Gu Yanan's bachelor apartment building.

Nan Hanfei sent Gu Yanan downstairs and left.

Gu Yanan was about to go upstairs, but found Gu Qingcen running over from the opposite side of the road in sportswear.

He had a white towel around his neck, and there were delicate beads of sweat on his head, and he looked like he had just returned from a night run.

Gu Qingcen stopped in front of Gu Yanan with a slight gasp, "Yanan, why did today's date end so early?" ”

"It's not a date...... Gu Yanan thought of Nan Hanfei's instructions, and the two couldn't tell anyone else about the terrorist organization, "We just talked about some routine work contacts." ”

Gu Qingcen had a smile on his face that was as warm as jade, he stretched out his hand and patted Gu Yanan's head gently, just like when he was a child, "If Yanan has a boyfriend, you must tell Brother Qingcen, I will stay by your side like Brother Jiashu, and if someone bullies you, I will help you beat you back." ”

Gu Yanan suddenly realized that in 7 years, the two had changed from childhood sweethearts to brother and sister on the surface, but she didn't understand why Gu Qingcen's smiling face at this time made people feel so sad.
