Su didn't ask who it was, but confirmed first: "Is it an employee?"

Yan Zhengwei was very sure: "Yes, senior sister, the management dare not take such a big risk. After all, if the virus is found out, the pharmaceutical factory will definitely be finished."

"I checked the batch of the drug. More than ten years ago, after the raw materials of the drug were imported into customs, the Kyoto Third Pharmaceutical Factory completed the final packaging and sealing process and then sold it. The entry and exit inspection was very strict, so the drug could only be mixed with viruses in the third pharmaceutical factory. And now it can be basically determined which workshop the employee in question is in."

Su also nodded: "Where are you now? I'll go find you and let's meet and chat."

Yan Zhengwei: "Okay senior sister..."

After hanging up the phone, Su Ye put down what he was doing, picked up the car key and was about to go out. Wen Ni raised her head in a daze: "Yebao, where are you going?"

Su Ye looked back at her and paused for a moment: "Go out and play, don't tell others."

Yan Zhengwei's tone was very serious. It seemed that this matter was extraordinary. Wen Ni was pregnant now and was not suitable to get involved in these things.

Wen Ni was filled with disappointment when she heard this: "I plan to come to you for a movie after get off work. Recently, a new crime movie was released..."

"Look at it someday."

As soon as she was halfway through her coquettish words, Su was impatient to flash.

...

Director's Office.

Yan Zhengwei was sweeping the floor with a broom. Secretary Xiao Yang came into the house to deliver documents. He was shocked when he saw this: "Director Yan, why did you sweep the floor yourself?"

After saying that, he reached out to grab the broom. Although Yan Zhengwei was old, he was very skilled. He didn't give Xiao Yang a chance. He turned sideways with a small ambition and directly avoided: "You can't sweep clean, I'll do it myself."

Xiao Yang blinked and didn't see what Director Yan had just done. He turned his head and found that there were prepared fruits on the coffee table next to him: "Director Yan, is there any leader on the top to come down to inspect?"

Yan Zhengwei glanced at him, and did not say yes, nor did he say no.

Senior sister, it is indeed his leader.

Xiao Yang thought for a moment and slapped his head: "By the way, you have to prepare another good cigarette, right?"

Before he could leave the house, Yan Zhengwei sternly hung him: "What cigarette? No one smokes, where did he learn corrupt ideas."

Xiao Yang scratched the back of his head and quickly lowered his head. Before Director Yan asked him to write an examination, he quickly slipped out of the office. He was wondering which leader who didn't smoke came to inspect. When he met, he saw a young girl about 20 years old walking over.

Su Ye pointed behind Xiao Yang: "Is the director's office there?"

Xiao Yang was stunned: "That... the director is going to meet important guests now, otherwise you can follow me outside first..."

Before he finished speaking, Yan Zhengwei heard the voice and poked his head out of the door with a kind smile on his face, which was completely different from the moment he had just said: "Yes? Come in quickly and taste the fruit is sweet or not?"

Xiao Yang: “…………”

Before he could react, he heard a 'bang' and Director Yan had already closed the door.

Inside the house, next to the coffee table.

Yan Zhengwei handed over a piece of information to Su Ye and then began to peel oranges for her.

It is Kyoto's No. 3 Pharmaceutical Factory, and the list of staff in all workshops that year.

Su also looked around: "Why are there no workshop 10?"

Yan Zhengwei put the peeled oranges in front of Su Ye: "This is the problem."

Su Ye raised his eyes and waited for him to continue talking.

Yan Zhengwei: "This medicine was taken from the Third Pharmaceutical Factory. The list of personnel in all workshops is on, but there are no ones in the 10th workshop. What does this mean?"

Su Ye frowned: "Even if he knew that the employee was in the 10th workshop, he had no information now..."

Itosa's helper has always been clean and has no handle.

"There is still a clue left," Yan Zhengwei smiled slightly: "Who told your junior brother, I am a policeman? Back then, there was a sensational serial case that has not been solved yet and has become a unsolved case. At that time, the person who was treated as a suspect was an employee of the 10th workshop of the Third Pharmaceutical Factory. However, the suspect later provided sufficient alibi... The date of the interrogation was just one month before the batch of drugs left the factory, and I suspected..."

Su Ye touched his chin with his fingertips: "Itosa's subordinates are on the condition of helping the criminals escape from the crime and letting the criminals spread the virus for them?"

Yan Zhengwei knocked on the coffee table: "That's right, if you add viruses to the potion, who will do it for them except for the vicious gangsters?"

Su also believed in his intuition: "If you guess correctly, the information of the suspect who was arraigned back then could not be found?"

Yan Zhengwei shook his head regretfully: "It has been too long since the incident was damaged, but there may be records in the confidential database, so they may not be able to delete it so thoroughly. However, it will take some time to find the information sealed in the confidential database. Whether it can be found in the final form is another question."

Su Ye's eyes fell to the file on the coffee table: "If the murderer commits the crime again now, even if all the information is deleted, we can catch him directly."

"That's right, but..." Yan Zhengwei suddenly had a bad premonition.

Su Ye turned his head slightly, and a fearless and fearless smile appeared on the corner of his lips: "It's not that a serial case, the criminal must have specific preferences. As long as a specific preference appears again, it is not impossible to tempt him to appear. Moreover, this pervert generally has a dependence on the location. Although the time has passed so long, he should still live in his original place."

After saying that, she leaned over to get the file on the coffee table. Yan Zhengwei reached out to stop it, but in the end she was one step behind Su.

Su Ye opened the file and the photos of the deceased were shocking.

The bodies were all showing signs of being molested or abused, but they were not attacked.

The locations are basically near Xuecheng Road, which is on the street behind Qing Dynasty University.

Based on the shoe prints, the criminal should be about 170 and weigh between 130 and 150.

The three dead were all women, with pure red dresses, long hair, petite figure and sweet appearance.

Yan Zhengwei took away the file and his tone was almost pleasing: "Senior sister, leave it to me for catching the prisoner, don't do it randomly."

Su also raised his chin and stood up: "Don't worry, I'm not a policeman, I'll go back first."

Looking at the senior sister's back as she left, Yan Zhengwei felt uneasy.

His senior sister never plays according to common sense in her work, and is not afraid of heaven or earth. Although her senior sister is skillful, the prisoner's methods are extremely cruel, and he must not let her take this risk.

Alas, I don’t know if my senior sister will be obedient…

Su Ye drove directly to the Su family after leaving the building. She seemed to remember that the Su family's granddaughter had a few pure red clothes?
