Although Lin Dong didn't understand computers, he was also full of curiosity when he heard the strange things that the tall and thin policeman said, and wanted to see the surveillance.

"Officer Wu, can you take me to see the surveillance? I'm curious. ”

Wu Lang nodded, and walked out first, Lin Dong pulled Liang Weiwei, and the three of them came to the security room, and the security guard opened the monitoring door, but the security guard's eyes were full of doubts when he looked at Lin Dong, because this security guard had seen Lin Dong, although he was not impressed, but when he saw Liang Weiwei behind Lin Dong, he immediately remembered it.

The security guard's puzzled look was noticed by Wu Lang, Wu Lang planned to wait for this matter and ask Lin Dong slowly, now he just wanted to see the surveillance, and under the busyness of the staff, the surveillance screen appeared in the eyes of everyone.

The picture was very normal at the beginning, the lights were on at the time of the crime, there was nothing abnormal, there was an immersion all around, and after a while, Chen Ailin's figure appeared in the picture, until everyone watched the whole video, and they didn't see Chen Ailin's murder, which also confirmed that the words of the tall and thin policeman were indeed full of strangeness.

Wu Lang, as an old policeman, has watched no less than hundreds of surveillances, and in his opinion, the more this is the more abnormal, and he began to have doubts in his heart, whether the murderer is a security guard! Because from the moment I entered this monitoring room, not to mention the security guards, but there are also security guards who move around at any time, if someone really changes it at will, then it is also possible.

Lin Dong didn't have any ideas at this time, because he didn't understand, but Liang Weiwei was different, after watching the whole video, three words suddenly popped up in his mind - alien, but he didn't dare to say it casually, he was afraid that Lin Dong wouldn't believe him and annoy him.

Wu Lang's idea lasted less than a minute before it was completely overturned, although the security guards here are all young and strong, judging from their proficiency in operating computers, it seems that they do not have the ability to change the program, but it is not ruled out that the security guards have the possibility of deliberately hiding, Wu Lang plans to try them to verify his conjecture.

Wu Lang pointed to the screen and said, "This big brother, please help me cut this section, and I'll take it back to the police station to take a look." ”

The security guard's face was full of embarrassment, staring straight at the security guard sitting on the side, and the other security guard nodded, and cut out the fragment that Wu Lang wanted by dividing it by two.

Wu Lang's temptation seems too idiotic to you, but imagine if a person who can't even cut the most basic can still cut the video and change the program? It is not ruled out that the security guard had the idea of deliberately concealing it, but Wu Lang is an old policeman with rich criminal investigation methods, and if he can't even see this, his police will do it in vain.

Now his suspicion of the security guard who helped him cut has increased slightly, and Wu Lang continued to probe again, this time he chose some computer office software, and repeatedly verified the object of his suspicion.

Wu Lang continued to probe tentatively: "Can you help me make a set of PPT?" ”

The security guard asked, "I don't know what type you need." ”

"It's okay, I said you do it, because I don't have a computer, and I can't do it."

The security guard nodded, looking at Wu Lang and motioning for him to continue, Lin Dong was even more curious, and became more and more unable to understand Wu Lang's thoughts, staring at the two of them curiously.

"Alright, officer, you say, I'm ready."

"Okay, I'm going to divide this video into many parts, the most important thing is that I need to cut each one, and then make it into a PPT and release it."

As soon as Wu Lang finished speaking, the security guard stopped and didn't do it, Wu Lang asked softly, "What?" Difficult? ”

The security guard scratched his head and said embarrassedly, "I'm sorry, I don't know what to do." ”

Wu Lang was not discouraged, and said in a soothing tone: "It's okay, you just do what you want." ”

The security guard nodded, and then started to produce, Wu Lang wanted to find suspicious points from the clues of the security guard, but soon after, Wu Lang completely overturned his guess, because in Wu Lang's opinion, the security guard made it was not a PPT at all, it was a kind of screenshot.

After Wu Lang hurriedly thanked him, the three of them exited the monitoring room, and Wu Lang, who went out, spoke first, "Lin Dong, do you know why I did that?" ”

Lin Dong said without thinking: "Is it for temptation? ”

Wu Langxi smiled and said, "Yes, I am testing them." ”

"Looks like you've got the answer you're looking for, right?" Lin Dong asked rhetorically.

The smile on Wu Lang's face did not dissipate, and he said lightly: "Yes, because after watching that video, a thought flashed in my head, that is, this is an insider crime, because from the perspective of our entry into the monitoring room, ordinary people can't enter that kind of place at all, so there is the scene where I test the security guard." ”

Lin Dong didn't think so, because he was not stupid, although he didn't have a city like Wu Lang, but he didn't understand this little thing, then he was really stupid, and it was simply hopeless.

Lin Dong smiled: "The result is that you have excluded them all?" ”

Wu Lang smiled bitterly: "I can't hide anything from you, but I have also gained something, although it is not them, but you haven't found out?" It's getting more and more mysterious, and I'm looking forward to it. ”

Lin Dong shrugged his shoulders and said, "I'm not as curious as you, I haven't figured out anything about myself, I don't dare to be curious about anything, haven't you heard a word?" Curiosity killed the cat! ”

The two of them didn't plan to continue to ask, but for a moment Wu Lang seemed to remember something, and said to Lin Dong: "Why did a security guard look at you with doubts when you entered the monitoring room?" ”

Lin Dong shook his head, "It seems that Officer Wu is really an experienced old policeman, and even such details can't escape your eyes, yes, didn't I tell you before?" ”

Wu Lang only paused slightly, and laughed casually: "Yes, I forgot." ”

After the two laughed, they planned to return to the scene of the crime, since there were no favorable clues in the monitoring room, it would be futile to stay any longer, and when the two turned around, they saw Liang Weiwei squatting in the corner, and smiled bitterly.

Wu Lang was not familiar with Liang Weiwei, so he directly provoked him, "Looking at a tall person, I still can't get rid of my crying problem." ”

Liang Weiwei didn't speak, Lin Dong pulled Wu Lang and signaled him not to continue, but Wu Lang didn't buy it, and his words became more and more excited, "You are a waste, a waste who loves to cry, even if Chen Ailin is saved by you like this, do you think she will like a waste?" ”

Wu Lang's words scared Lin Dong enough, because he was very familiar with Liang Weiwei, his self-esteem was very strong, and he didn't take the initiative to like someone during school, and now such a sentence came out.

Now Wu Lang's words are simply worthless, he is really worried that Liang Weiwei can't stand it, and it will be bad if something unpleasant happens.

Lin Dong suddenly found that it was very uncomfortable to be mixed between the two, but to be honest, Lin Dong was biased towards Liang Weiwei, because his relationship with Wu Lang was not good, and he also believed that Liang Weiwei would not be a bastard enough to dare to attack the police, except for last time, of course, Wu Lang didn't plan to care, otherwise it would be difficult for anyone to come.

Lin Dong whispered in his heart not to move, but when Liang Weiwei's hand was raised, Lin Dong's heart was about to jump to his throat, but Liang Weiwei just raised his hand, and slowly put it down after a while.
