The crackdown on organized crime began with the arrest of the mother-in-law.

Chapter 681 Director Qin, you may have the wrong person. I don't know that student.

Under Zhang Qiang's organization, the more than 20 people were quickly evacuated, leaving only Qin Chuan and Song Baodong in the tobacco laboratory.

Song Baodong was also a little puzzled, not understanding why Qin Chuan had dispersed everyone else after seeing him.

"Director Qin wants to speak with me privately, is there something you need?"

Qin Chuan shook his head and pointed to a pair of chairs in the laboratory.

"Professor Song, please have a seat."

Qin Chuan and the other party faced each other.

How many years has Professor Song worked at Linzhou University?

Song Baodong took out a box of cigars, pulled one out, and handed it to Qin Chuan.

"After graduating from university, I started working at Linzhou University. I worked my way up from teaching assistant to lecturer to associate professor, and now I am a professor. I have been working in the tobacco industry for more than 20 years now."

Qin Chuan accepted the cigar.

"Twenty years is not a short time. In a few more years, Professor Song may retire. Does Professor Song usually like to smoke this kind of cigar?"

Song Baodong nodded.

He wasn't as particular about smoking cigars as others; he would take them out, cut off the seal, and light them with a regular lighter.

“People like us in the tobacco industry deal with these things every day. I used to smoke, but I quit and started doing sputum extract because it doesn’t go through the lungs, so it’s less harmful to the body. But it has a stronger flavor, so I gradually developed this habit.”

"Director Qin has also studied this?"

After Song Baodong lit the cigar he handed to Qin Chuan, Qin Chuan tried it twice.

Qin Chuan shook his head. He didn't usually smoke cigars, and he didn't smoke cigarettes very often either.

"I don't know much about cigars, and I don't usually smoke them, but I'm quite sensitive to the smell. There's a director in our bureau who smokes cigars regularly."

"It's quite a coincidence that I smelled a very familiar scent in the lecture hall where Gao Yunfeng was killed. I couldn't remember it at first, but when I passed by the teaching building just now, I suddenly smelled the same scent again and realized that it was the smell of a cigar."

Song Baodong's expression froze for a moment, but he quickly recovered.

"Really?"

Qin Chuan looked at the other person.

"Professor Song, don't you find it strange? How could there be a smell of cigars at the scene where Gao Yunfeng was killed? Although the scene was covered by the smell of blood, I have a naturally sensitive nose."

Could you explain this to me?

Explanation?

Song Baodong shook his head: "I don't know about that. Solving cases is your profession as police officers, and I'm not good at that."

Qin Chuan nodded.

"That's true. Professor Song's expertise is in tobacco, so he's not exactly an expert in murder. However, he scratched Gao Yunfeng's skin multiple times, which is why it took more than an hour to peel off Gao Yunfeng's skin, right?"

Ok?

"Director Qin, what do you mean... I... I don't understand."

Zhang Qiang then realized that Qin Chuan suspected Song Baodong was actually the murderer of Gao Yunfeng.

But that shouldn't be the case. According to the current investigation, Gao Yunfeng and Song Baodong have no connection whatsoever, and they shouldn't know each other.

Wow! Yunfeng is a student in the School of Economics and Management, majoring in International Finance.

Song Baodong is a professor in the tobacco industry, and the two are very different in age, so they shouldn't have any academic interaction. How could Song Baodong be the murderer of Gao Yunfeng?

Sure enough, Song Baodong continued.

"Director Qin, I understand that you police officers are eager to solve the case, but I don't know that student. He's not in our field. I don't know any of them. How could I possibly say that I killed him?"

"Besides, while there was a smell of cigars in that classroom, it doesn't necessarily mean that I was the one who smoked them. Blood was drawn at school. I couldn't have been the only one who did it, so if you suspect me because of this, I think it might not be rigorous enough."

"Director Qin, I think my personal reputation is quite important. If you try to frame me for something so baseless, I will definitely report it to my superiors."

"So I won't keep you company today. If you don't have any evidence, you're welcome to come find me anytime. But if Director Qin comes to me again with the same excuse, then I'm sorry I won't keep you company."
