Next, Zheng Linfeng introduced the case and the investigation situation to Li Yu and Ou Liwen. He said some details in a vague way, which Ou Liwen could understand. When it comes to the matters of 1206, even Zheng Linfeng himself could only get in touch with part of the truth, and confidential matters would not be revealed casually.

According to Zheng Linfeng, the leader who came down from the capital was named Zhang and went to Institute 1206 to check the progress of the C project. He first went to Qihua to hold a discussion with the personnel of the Yunjiang Provincial Science and Technology Bureau to understand the military research situation in the province. After the Yunjiang Provincial Science and Technology Bureau reported on his work, he warmly invited Leader Zhang to the banquet. Because the Science and Technology Bureau's own canteen could not make any high-end banquets, the Science and Technology Bureau arranged to receive Leader Zhang at the newly opened Baicao Medicinal Food Shop. Baicao Medicinal Food Shop is currently the most popular hotel in Qihua. The Science and Technology Bureau also found some contact to book a private room.

When leader Zhang came to Yunjiang Province, he brought a laptop with him. According to regulations, if he left the Science and Technology Bureau and went outside, he should hand over the laptop to the confidential room of the Science and Technology Bureau for safekeeping, and should not carry it with him. He didn't know what the leader Zhang had made or was worried about letting the laptop out of his sight, so he took the computer to the medicinal meal shop.

Leader Zhang stayed at a hotel within the Science and Technology Bureau. He boarded the bus to the medicinal meal shop in the hotel, got off the bus and went directly into the private room. After dinner, he left the private room with everyone and got on the bus and returned to the hotel. During this period, no other outsiders had the opportunity to contact him. As usual, there would be no problem. This is why Leader Zhang dared to take the computer out.

But this impossible thing happened. After leader Zhang returned to the hotel, he opened his computer bag and found that the computer in the computer bag was no longer the same one he had. In other words, while they were going out for dinner, someone implemented a bag transfer plan on him.

"Can you find any clues from the computer you changed?" Ou Liwen asked.

"There is no clue at all." Zheng Linfeng said, "We found the seller through the barcode on the computer, and followed the clues to find the buyer of the computer. The buyer admitted that he did buy the computer and it took him more than a year. The day before the accident, he was stolen on his way off work."

"Is it true?" Ou Liwen asked.

"It's true. This buyer is an ordinary white-collar worker in a company and has nothing suspicious about it. Many of his friends know about theft of the computer. He has also posted this on WeChat."

Ou Liwen said: "In other words, our opponent knew in advance what type of laptop Zhang was carrying, and found a thief with superb skills and stole a computer of the same model one day in advance for the next day's bag adjustment. So, who can know in advance the model of laptop Zhang used?"

"There are too many of this." Zheng Linfeng smiled bitterly, "Leader Zhang has taken this computer to many places, and cadres from subordinate units know this situation."

"..." Ou Liwen was speechless. This clue seemed to be of no use. She thought about it and continued to ask: "Who were the people who accompanied Leader Zhang at that time, and how was the investigation of these people?"

Zheng Linfeng said: "There are director of the Science and Technology Bureau, deputy directors Xie Xuecheng, Shan Xiaying, and 1,206 deputy chief engineer An Xiyou who came to report the work from Yuhai..."

"General Engineer An?" Ou Liwen said in surprise, "Why is he here too?"

When Ou Liwen is doing safety work in Yuhai, she naturally has to deal with important figures from the 1206 Institute and meets An Xiyou, who Zheng Linfeng just mentioned. She knows that An Xiyou is a deputy chief engineer in charge of the assembly of nuclear submarines. She is in her 50s and is easy-going. She has worked in the 1206 Institute for more than 30 years. In his own words, she devotes her entire youth to the national defense science and technology industry. Ou Liwen has a good impression of An Xiyou and asked questions at this time. It was just because he came from Yuhai, and she wanted to ask the reason.

Zheng Linfeng said: "Leader Zhang and Chief Engineer An had a good personal relationship in his early years. This time he came to inspect the work of the 1206 Institute. Therefore, the Science and Technology Bureau invited Chief Engineer An to come to Qihua. On the one hand, he reported on the work, and on the other hand, he also accompanied Chief Engineer Zhang. It is convenient for both public and private."

"I understand." Ou Liwen nodded, and then asked some other details.

Li Yu sat next to him, listening to their conversation carefully, while analyzing the problem in his heart. He was a killer and was best at seeing the small things and finding clues from any clues. After listening to the two of them for a long time, he felt that Zheng Linfeng and the others were still confused at the moment, and understood why they were holding Yan Chunyan, because Yan Chunyan was indeed the only breakthrough they could find.

"Li Yu, what do you think?"

After asking the questions he wanted to know, Ou Liwen turned to look at Li Yu and asked.

Li Yu shook his head and said, "I can't hear any problem. Otherwise, I will go back to the medicinal restaurant to chat with my employees to see if they have any clues."

"It's good. Director Zheng, why don't you let Li Yu go back to the medicinal food shop first. Some things he asked are different from what you asked about. Maybe he can ask some new clues." Ou Liwen asked Zheng Linfeng for advice.

"That's thank you for your hard work," Zheng Linfeng said. After saying that, he quickly reminded him: "Xiao Li, you should pay special attention to keeping the situation of the case confidentiality. These situations should not be circulated outside the world."

"I understand, Sister Ou taught me the confidentiality rules." Li Yu replied.

Rejecting Zheng Linfeng's invitation to eat, Li Yu left the Qihua Security Bureau alone, took a car at the door, and went straight to the Qihua branch of Baicao Medicine Restaurant. Ou Liwen and Zheng Linfeng stood at the window of the director's office and watched him leave. Zheng Linfeng smiled and said, "Xiao Ou, which one are you singing for me? Why did you get such a child to help us solve the case?"

Ou Liwen smiled and said, "Director Zheng, I also made a temporary decision. I think the case happened in the Medicinal Food Floor. He is the boss of the Medicinal Food Floor. Some investigations may have an advantage over you, so I proposed to let him participate."

"Haha, then you pretended to be the imperial edict, saying it was the meaning of Director Han." Zheng Linfeng said. He did not mean to blame Ou Liwen, because when Ou Liwen told him about this, he secretly gave him a wink while Li Yu was not paying attention, and he knew that there was something else. When he introduced the case to Li Yu and Ou Liwen just now, Zheng Linfeng did not reveal the truth, but retained it, which was also out of vigilance against Li Yu.

Ou Liwen sighed and said, "Judge Zheng, in fact, I said this is what Director Han means, and it is not a fake imperial edict. Li Yu is a man with outstanding martial arts and extraordinary intelligence. He is a good seedling that our Director Han is targeting. But the problem is that his life experience is very suspicious. He is a person with no origin at all, which makes us feel a little cautious about him. Director Han specifically explained to me, allowing me to create opportunities to test him and judge whether he is reliable. Our current case is actually a touchstone, which can test his quality."

"Do you use us as bait?" Zheng Linfeng said with a fake face on the floor, "No, no, I have to find a call for Director Han. He wants us to help him test this Li Yu, at least, he has to invite me to have a drink?"

"Haha, Director Zheng, I owe this wine first, I'll treat you back." Ou Liwen said readily.

The two of them joked, and Ou Liwen returned to her serious expression and asked, "Director Zheng, can you and me understand the secret? How high is this laptop of Zhang? "

"It's basically zero." Zheng Linfeng said, "There are mainly some speeches and some semi-public information, which are not highly confidential. Leader Zhang is a technical leader, but he has a strong sense of confidentiality. When he went out, he did not bring his own work computer, but a computer specially used for business trips. However, this was said by him after he lost the computer, and our opponents did not know this in advance."

"Good luck." Ou Liwen's heart was relieved. It was not a top-secret information, so everyone would be under much less pressure. Even if the laptop could not be retrieved, or if the opponent copied the information away before it was retrieved, it would not cause any losses to national security.

Zheng Linfeng sighed: "It is indeed a blessing in disgrace. However, this case happened and its nature is very bad. This shows that there are huge loopholes in the security protection work in our Qihua City. If the case cannot be solved in time, the Qihua Security Bureau will be covered with a big stain."

"I understand." Ou Liwen said. A big leader came to you and was stolen when he went out. What a shame. Not to mention losing a laptop, even if he lost a handkerchief, it would be a dereliction of duty by the security department. It is no wonder that Zheng Linfeng, Xu Jing and the others were so crazy.

"Director Zheng, I feel that should we start with the accompanying staff of Leader Zhang and check whether there is a possibility of an insider committing a crime? According to you, no outsider has ever contacted Leader Zhang. Although the restaurant waiter Yan Chunyan has entered and exited the private room, it is still very difficult to get close to Leader Zhang and complete the transfer plan. Even if she has problems, she must be able to work with others to succeed." Ou Liwen analyzed.

Zheng Linfeng nodded, lowered his voice and said, "I'm going to tell you, this is also our analysis. However, the ones accompanying Leader Zhang are either the leaders of the Provincial Science and Technology Bureau or General Engineer An. Everyone is not a simple person. Although we have doubts, we dare not act rashly. As you said, to complete the transfer plan, we should cooperate with the inside and outside. We must now focus on finding this outside partner. Only by finding him can we find the insider, and we will not be wrongly accusing the leaders of the Science and Technology Bureau for no reason."
