In front of Qin Haifeng, Cao Xuan didn't communicate with Qin Yu, the two just exchanged a look, and they understood each other's intentions.

To be honest, Qin Yu and Cao Xuan would not believe Qin Haifeng's words, at least, the appearance of the corpse powder in the laboratory could not be explained.

Cao Xuan walked in front with Qin Haifeng, but Qin Yu deliberately slowed down and walked last, and even distanced himself from the large army in front.

Of course, Qin Yu didn't do this to go back to the utility room to check on something, because Qin Haifeng had already closed the door of the utility room, he was just thinking about something.

"Qin Yu, do you think this Professor Qin is a little weird?" Not only Qin Yu, but Meng Yao also walked behind, watching the person in front of him walk away, and asked softly towards Qin Yu.

"Oh, did you find anything? Qin Yu asked with a smile.

"What do you think, this Professor Qin said that he was not kidnapped, but he was not kidnapped, why did he throw away the key that he usually looks at, if he is not kidnapped, even if he leaves, then he should leave a note for Miss Chen, or send a text message, and a very important point, Professor Qin said that he saw Miss Chen lying on the table and fell asleep before leaving, but Miss Chen told us before that she walked into the laboratory and passed out, which is not right at all, unless Miss Chen lied to us. Meng Yao said seriously.

Qin Yu looked down at Meng Yao, "Yes, you can be a female detective, you can observe very carefully." ”

"Don't laugh at me, as long as you have heard Miss Chen's previous words, you can think of these things, but if Professor Qin lied, then why did he lie?" Meng Yao glared at Qin Yu, and then asked in confusion.

"Anyone who lies has a purpose. Qin Yu replied lightly, while looking ahead, and said softly: "Tell you something, guess the moment I opened the door." What is this Professor Qin doing?"

"What are you doing?"

"This Professor Qin, sitting cross-legged, has a black statue in front of him. It is very small, about 10 centimeters in height. ”

"Statue, sitting cross-legged, and that music, isn't it ......" Meng Yao's face showed a look of shock, "This Professor Qin can't have joined some cult organization, right?" I've seen a lot of news reports about the members of those cults. ”

"I don't know if it's a cult organization, but there's another thing that's interesting. The corners of Qin Yu's mouth curled slightly, "If it were you, you were doing something in the room, and someone suddenly broke in, what would your first reaction be?"

"To see who's in, of course. Meng Yao replied without thinking about it.

"But what if it's pitch black?"

"Then I'll open my mouth and ask the other party, "Who is it?" Meng Yao replied after thinking for a while.

Listening to Meng Yao's answer, Qin Yu's eyes narrowed and he said, "Yes." Normal people's reactions are like this, but this Professor Qin, when I pushed the door open, his first reaction was not to ask "who it is", but to put the little man on the ground into his pocket, and then immediately turned off the radio, and then, his eyes searched left and right, and he actually wanted to find a place to hide. ”

Listening to the picture described by Qin Yu, Meng Yao suddenly felt a little cold in his hands and feet. A trembling voice asked, "Qin Yu, how did you know?"

"Because of this bit of darkness, to me there is no difference from the daytime, and we, Professor Qin, thought that no one saw his movements. In fact, his every move was under my watchful eye, and when he heard Chen Qingzhi's voice, the first look on his face turned out to be a look of complaint, and the moment Cao Xuan turned on the light switch, it returned to normal. ”

"Qin Yu. This Professor Qin is very suspicious, and Miss Chen is still following him, I think it will be dangerous. Meng Yao felt a little terrifying just thinking about the picture of Qin Haifeng alone in this utility room, in such a quiet and damp basement, he dared to stay alone and meditate, and when he heard someone coming, his first reaction was to hide......

Meng Yao's eyes lit up, "Unless this Professor Qin is a thief and doesn't want to be discovered." ”

"Yes, but this is his own utility room, why should he be the same as being a thief?" Qin Yu took over, a glint flashed in his eyes, "This Professor Qin has a lot of secrets hidden in him. ”

"Then what should we do, do you want to poke him?" Meng Yao asked.

"There's no hurry about this, before that, let's figure out who kidnapped him. Qin Yu's face raised an arc, Qin Haifeng's lies were easy to debunk, as long as he got the school's video surveillance, he could see it at a glance.

……

"Thanks to Professor Qin's cooperation, we all understand the matter, but fortunately it was a false alarm. At Qin Haifeng's house, Cao Xuan shook hands with Qin Haifeng with a smile and said.

"I'm really sorry to cause trouble to my comrade police. Qin Haifeng showed a look of shame on his face and apologized.

"Where, it's our business, okay, since it's okay, then we'll leave first. Cao Xuan saw one of his subordinates walk in from the door, glanced at him, and knew that he had made a new discovery, so he immediately said goodbye.

"Alright, I'll send you. Qin Haifeng sent Qin Yu and his party downstairs to the unit, and wanted to send them again, but was stopped by Qin Yu when he opened his mouth.

"Professor Qin, don't send it, oh yes, Miss Chen, I left something at the school, can you accompany me to pick it up." Qin Yu said to Chen Qingzhi with a smile.

"Absolutely. Chen Qingzhi nodded, her mind was still full of questions at the moment, although the mentor was safe, but she always felt that there was something wrong with it.

Chen Qing got on Qin Yu's car, as before, Cao Xuan and his party drove a business car to open the road in front, through the rearview mirror, Qin Yu could clearly see that Qin Haifeng was still standing downstairs in the unit, waving at them, until the car turned a corner and Qin Haifeng could not be seen.

"Mr. Qin. ”

"Miss Chen. ”

Almost instantly, Qin Yu and Chen Qingzhi shouted at each other at the same time, and Meng Yao, who was sitting in the driver's seat and driving, snorted and said, "Do you two want to be so tacit." ”

Chen Qingzhi showed a hint of embarrassment on his face, but soon this embarrassment was driven away by the confusion in his mind, and he continued to ask Qin Yu, "Mr. Qin, do you think that my mentor's affairs are a little strange?"

"Of course, do you really believe what your mentor said, he came back here because things were left at home?" Qin Yu smiled, "You don't know yourself, did you faint, or were you tired and lying on the table?"

"But why did the mentor lie?" Chen Qingzhi was puzzled, if the mentor was really arrested, why didn't he say it, and hide it from them.

"That's up to your mentor himself. Qin Yu said meaningfully.

At the same time, the business car of Cao Xuan and his party in front stopped, and Cao Xuan got out of the car and walked towards this side.

"Master Qin, just now my subordinates reported, they called up the school's surveillance video to inspect, sure enough, half an hour before you appeared in the school, a van drove into the campus and went to the experimental building, and then after ten minutes, Qin Haifeng's car led the van out of the campus, judging from the picture displayed in the surveillance, Qin Haifeng's co-pilot position was a man in black at that time, but what exactly he looked like, but he was not photographed by the surveillance, the other party is obviously also a master in this area, and the picture displayed in the surveillance has always been with his head down。 ”

Listening to Cao Xuan's words, Qin Yu and the three of them glanced at each other, especially Chen Qingzhi, not only did she not solve the confusion in her heart because of this, but she was even more confused, her own mentor, why did she lie?

"Master Qin, what should we do next, do you want this Qin Haifeng?" Cao Xuan made a gesture to bring back for interrogation, but Qin Yu shook his head and vetoed it.

"Don't worry, Qin Haifeng is a professor after all, and he hasn't done anything illegal, and he is easy to startle snakes. Qin Yu replied.

Cao Xuan listened to Qin Yu's words, but a trace of disapproval flashed on his face, with the particularity of their department, if they want to arrest a person, they don't need to see if the other party has violated the law, their department has a special power, and anyone who feels suspicious, or they think, will bring unstable impact to the society, some dangerous elements can be directly arrested.

"Director Cao, there is something very important to me that Professor Qin has in his hand, if you can, I hope you can spy on him secretly, and in addition, help me investigate where he has been going for ten days and half a month that he has often disappeared in the past few years. Qin Yu opened his mouth and said to Cao Xuan.

"Master Qin, don't worry, I will send someone to keep an eye on Qin Haifeng twenty-four hours a day. Cao Xuan agreed.

"That's right. Qin Yu looked at Chen Qingzhi again, "Miss Chen, don't tell your mentor about today's matter, besides, if your mentor asks you if you have seen his key, you can directly tell him that the key was taken by someone from the Public Security Bureau." ”

"Hmm. Chen Qingzhi hesitated, but finally nodded and agreed.

"Also, don't tell me who I am, don't say I'm the one who can unravel the hexagrams, if your guru urges you to contact me, you can tell him that the phone can't get through. ”

When Qin Yu said this, his eyes flashed, what secret Qin Haifeng has, it won't take long to know, without the key, Qin Yu believes that the other party will either contact Cao Xuan and them as soon as possible to get the key back, or go to the place where the safe is hidden and find a way to get the contents out.

However, no matter which outcome it was, his whereabouts would be exposed, and Qin Yu believed that with Cao Xuan's ability, it would not be a problem to spy on an elderly scholar.

PS: This chapter should have been written last night, but when it came to Qin Haifeng's strange behavior, Jiu Deng's own cold hair stood up, and in the end he had no choice but to write it during the day.

Well, it's already in the middle of the month, do you have a monthly pass, if you have, vote for Jiudeng, three more guarantees every day, it's worth a monthly pass in everyone's hand. (To be continued.) )
