The system is the king of the counterattack master

According to K's instructions, Han Xiaodong found that video, but what surprised him was that there was nothing special in that video, because it was early in the morning, the whole video was just a fixed picture, facing the warehouse corridor shot.

"There's nothing here." Han Xiaodong read it several times, but couldn't see anything, so he had to ask K for help.

K didn't make any detours, and directly reminded: "Look at the beginning, it's 3 o'clock sharp."

Han Xiaodong adjusted the time to 3 o'clock according to K's prompt, and checked it several times, but he still didn't see any difference.

"Slow down, put it to the slowest." K pointed speechlessly.

Han Xiaodong had no choice but to turn the dial on the video controller to watch the picture frame by frame.

Suddenly, his eyes lit up, and he switched back and forth between the two frames.

Eriksson, who was standing by the side, saw that his expression suddenly became tense, and knew that he must have discovered something, so he asked behind him in a low voice, "How is it? Have you found any clues?"

"How many frames per second is your monitoring screen?" Han Xiaodong asked, pointing at the screen.

"The most advanced high-definition monitoring equipment we use can reach 60 frames per second. Is there any problem?" Eriksson was a little puzzled by his question.

“那为什么2点59分59秒的画面只有59帧？而3点零一秒的画面却有61帧？” 韩晓东边说，边一直在两个画面间切换个不停。

This is an extremely subtle detail. Eriksson had never thought of it before, and no one had paid attention to it. He quickly sat on a chair and watched the video surveillance carefully.

Due to the use of 60-frame equipment, the picture is 0 frames per second, that is to say, the time recorded on each frame of image should not be repeated, from 59 to 2, there is absolutely no error, but in At the position where Han Xiaodong stopped, the time was fixed at 59:59:58:3, and the next frame directly changed to 00:00:00:3. Moreover, this 00:00:00:[-], unexpectedly Two, exactly the same.

"This...it's impossible!" Eriksson looked at the video in shock, his eyes staring like light bulbs. He watched these videos with more than a dozen policemen for half a month, but he didn't find this problem. .

Surveillance is absolutely infallible, the only possibility is that the video has been changed.

"How did this happen? These videos have never been out of the monitoring room at all, how could they be replaced!" Eriksson held his head in his hands, obviously extremely annoyed by the situation in front of him.

"It's very simple. I recorded the video of this time period before, and then at the same time, switch the signal to replace the original video. After committing the crime, just switch the video back. Just pick a time when there is no one. It won't be discovered easily." Han Xiaodong kindly explained for him.

"But the camera is turned on 24 hours a day, and the data is encrypted and stored. How could someone replace the contents?" Eriksson still couldn't agree with Han Xiaodong's explanation. His excessive trust in high technology made him lose imagination.

"The camera is on, so there is no way to replace what's inside? As long as someone helps them get in touch with the surveillance signal transmission network, it is not impossible to intercept and replace the surveillance images of a certain period of time during the transmission process. Yes, although it requires a very high level of masters to do it, it is achievable after all.”

Han Xiaodong was a little speechless, and thought that this guy must have watched few movies. It is no secret that this guy has been arranged as a bridge for a long time. At least he can do it by himself. Turn your muscles, you must think that it is impossible for someone to change these data?
Eriksson didn't seem to understand these high-end technologies very well, but since the FBI agents had said so, he had nothing to say. He just opened his mouth a few times, but didn't make any sound.

In fact, while revealing the secrets of the entry and exit methods, Han Xiaodong already had an idea in his mind. If the surveillance video can be replaced, it means that this matter must have been done by collusion between the inside and outside, at least an internal response. It is not difficult.

"It seems that we can put the suspect on the guard that day." Eriksson seemed to have thought of this, and murmured.

Han Xiaodong glanced at him, thought about it carefully, and finally nodded and said: "There is some truth, but I think we need to pay attention to it. This method is too professional and has a strong purpose. It is obviously aimed at this batch of parts. Yes. The production of these parts started half a year ago, so there are only two possibilities. One is that the guards were bought by others, and the other is that the guards were recruited recently. I prefer the latter. Of course, you need to investigate this gone."

He said so without basis. According to the information provided by K, the processing technology of this new material was only developed in the last year, and the contract was signed more than half a year ago.

That is to say, if someone is eyeing these things, unless he has the ability to predict, it is impossible to lurk here as a guard a few years ago.

Even if he is a guard, according to his skills, in the past few years, the theft of this special metal processing technology may not be a problem. There is really no need to take the risk of only a few parts, and finally kill people , which cannot be committed.

Therefore, he deduced that this matter was definitely not done by the long-term guards, and even if it was, it was just for convenience, not the person who did it.On the contrary, those who join for a short period of time are the most suspected.

Speaking of those who joined for a short time, a face suddenly flashed in Han Xiaodong's mind, and he immediately asked, "When did Mr. Larson join you?"

His question stunned Eriksson for a moment, then he smiled and waved his hands: "It won't be him, he is a former FBI agent, we have done due diligence on him, he would not do such a thing .”

Han Xiaodong heard that this answer had two meanings. One was that the time Larson joined should meet the requirements for committing the crime, and the other was that Eriksson and the others seemed to have thoroughly investigated this person.

However, according to K's information, Larson is not some kind of FBI, so the credibility of Ericsson's investigation is now in Han Xiaodong's mind, it will be greatly compromised.

"Understood. It's getting late. I have to report what happened today to the headquarters. In addition, is there any hotel here? I don't think there is any place to stay near here. Although the weather is not bad, but , I don't want to sleep in the car yet."

Han Xiaodong spread his hands and joked.

Seeing this, Eriksson immediately took out a key from his pocket and handed it to Han Xiaodong: "The room has been prepared for you. We have no place to live here except for the apartment in the castle. Let me show you the key." to your room."

Hearing that there is already a place to live, Han Xiaodong is naturally very happy, followed Eriksson out of the monitoring room, and went straight to the outermost building of the castle.

This is also a building similar to the style of the old castle, but the shape is more modern, and it is close to the side of the mountain, and you can see the scenery of the mountains outside.

The room allocated to Han Xiaodong was a good place to watch the scenery. After Eriksson sent him to the room, he asked him about the meal time, thanked him and left.

Han Xiaodong stood by the window, made himself a cup of coffee, looked at the mountains in the distance, and silently calculated the next plan in his heart.

More than ten minutes later, when he was in a daze, there was a knock on the door.

Han Xiaodong looked back at the gate, he frowned slightly, in this old castle, who would come to him?
