(Today is the third day of the two-shift beast!)

"Huh? No." Qi Yi came back to his senses, his perverted expression instantly faded, and said: "It's beyond the scope of our investigation capabilities. Please report the situation and apply for technical support."

The little brother looked at him suspiciously, then took a step back and said, "I have already called the superiors. You can report the details again. Well, if I don't have anything to do, I will continue to repair the optical cable."

"Wait a minute," Qi Yi called to him: "Did you see anything strange when you were doing maintenance here at noon?"

The little brother took a step back again and shook his head: "No, and I'm not here most of the time. I'm wiring inside."

"Okay, go ahead."

The little brother immediately took the satchel and left.

As soon as Qi Yi walked back to the main entrance, he saw Lao Chi just getting out of the car and walking this way, saying hello: "Lao Chi, how are you? Are you done?"

Lao Chi hooked Qi Yi's shoulders and walked inside: "It's done, it went smoothly. He promised to help us collect information."

He hooked Qi Yi's shoulders and walked with him while saying, "This friend of yours is indeed quite capable. I only revealed a little bit of insignificant information, and he guessed a lot of things."

Qi Yi instinctively wanted to slap his hand away, but he hesitated and held back.

Lao Chi continued: "But he also said that even if we were lucky enough to guess correctly, the matter must be very secret and difficult to investigate, otherwise the truth would have been exposed back then.

The victim may not have even called the police. Apart from the residue of the Yin Dao valve, no other traces were left. In addition, it has been so long and it is difficult to find clues. The breakthrough may still be on the Internet. The victim may have complained about this online.

thing."

After Qi Yi listened quietly, he said: "It is true that the original report record of the deceased was not found. Maybe she chose to hide it out of some concerns, or maybe we guessed wrong. There was another reason for her damaged valve, and she was not reported.

Defiled."

"So, I'm afraid your friend won't be able to find anything," Lao Chi said, "otherwise, why not look for Xiaoyu again? Tell her clearly and she will agree."

"Now it's not a matter of whether she is willing or not. It's not very authentic to drag people down with such illegal things."

"That's what you said." Lao Chi felt uncomfortable: "Then you drag me into the water and you're just being honest?"

Qi Yi didn't even raise his head: "Didn't you come here on your own?"

Lao Chi choked and said nothing.

Then he realized that the two of them had actually reached the second floor, and he couldn't help but ask: "Where are we going? Isn't it your office?"

"Go find Xiaoyu and copy the data package." Qi Yi said, "By the way, I'll ask her about the results of her investigation into the surveillance video... By the way, there was a problem with two cameras in the detachment's backyard last night. Do you know about this?"

"

"I know," Lao Chi nodded: "At that time, detachment Wang asked me to go take a look. I went and found that the camera itself was fine. It was a network transmission problem."

"You know it and you won't tell me?"

Lao Chi was confused: "Why should I tell you?"

Qi Yi stopped and slapped his arm off: "Fuck, I've always suspected that there was something wrong with our detachment's surveillance. I asked Xiaoyu to help me check it several times. Don't you know about this?"

"Uh..." Lao Chi felt guilty, his eyes darting around.

"Forget it, forget it," Qi Yi lost his temper and was too lazy to talk to him anymore and continued to walk forward.

Lao Chi hurriedly caught up and asked: "Do you think the problem with the camera is related to what happened in the past two days?"

Qi Yi said: "It's still unclear whether there is any connection, but it must be related to a strange thing."

Lao Chi hurriedly asked: "What's the matter?"

"We'll talk about it later." Qi Yi shook his head. They had already reached the place. Qi Yi knocked on the door and walked in directly.

Jiang Xiaoyu does not have his own office. Four people work in the same room, with Jiang Xiaoyu in the innermost position.

"Brother Yi, you are here," Jiang Xiaoyu handed him the USB flash drive and said, "The data of Gaohuicheng has been copied inside. The data of the deceased who fell from the building will be later. Can I give it to you before get off work?"

Qi Yi took the USB flash drive, thanked him, and asked, "Is there anything wrong with the surveillance video?"

Jiang Xiaoyu's expression immediately became serious: "Something did go wrong."

"oh?"

“Did you know that there are two cameras in the backyard with high network transmission latency?”

"I heard what Sun Gong said."

Jiang Xiaoyu hummed and continued: "At noon, when Sun Gong used external optical fibers to temporarily connect the two monitors to the intranet system to correct the network clock and delay, I found that every camera in our detachment had a five-second delay.

.”

Lao Chi hurriedly asked: "Delay in unification? What's going on? What does it mean?"

He still had something, but not much. He felt keenly that something was not right, but he couldn't tell what was wrong.

"It's hard to say what happened right now. It may be a system time issue, and we don't rule out the possibility that someone has made malicious adjustments."

Speaking of this, several people felt a twinge of sadness on their backs.

"If it's the latter, it means that someone can see the video five seconds ahead of us. For those with good technology, they can cut off the problematic footage in advance and recycle the previously recorded footage."

Qi Yi asked: "In other words, scenes like someone knocking on the door of the anatomy room or entering my lounge can be easily eliminated without being discovered, right?"

Jiang Xiaoyu replied: "Yes, and the task of monitoring the detachment is very easy. We don't even have a full-time monitor, so it is difficult to find the problem at the first time. Afterwards, they have a lot of time to process the picture more smoothly."

"Of course, this is just the worst possibility, and it can even be said to be a conspiracy theory.

Our system uses an internal network, so there is no possibility of external attacks. Moreover, I quickly checked all the computers in the detachment and found no problems. Intellectually, I am more inclined to system errors, but intuitively..."

Lao Chi was not satisfied with this answer and asked: "You can't rely on intuition when handling cases. Can you be more precise?"

"Not at the moment, give me some more time. I always feel that the code data of the few videos that Brother Yi asked me to check are not quite right. It shouldn't be a simple delay problem. I'll confirm it again."

Jiang Xiaoyu had nothing to say on the technical side. Lao Chi was unsure and turned to look at Qi Yi: "Lao Qi, what do you think?"

Qi Yi can feel the same.

The first time he saw the perpetrator pretending to be him and stealing the body, he felt something was strange, but he could never explain it.

"Why don't you try using that video as a breakthrough? It's the part where the impostor specifically raised his head and looked at the camera."

Jiang Xiaoyu agreed: "Okay, I'll take a look at it when I have time."

"Don't be in a hurry. You've got too many things going on lately, so just take your time. If there's nothing else, I'll leave first."

"Okay, before I get off work, I'll send you the data package of the deceased who fell from the building."

"Thanks."

The two walked out of the office. Lao Chi felt that the back of his head was numb, as if a big net had been swung down. They were already in the game, but they didn't even know who their opponent was.
