"When did you lose your phone?"

"Last night." Zhang Hengdao.

"Well, which building do you live in?"

Zhang Heng reported the building number of the college student to the young man in charge of the monitoring room.

"2 units and 5 buildings?" The young man in charge of the monitoring room was a little surprised when he heard this.

"What's wrong?"

"Ah, no...... It's nothing. The young man opened his mouth, but at last swallowed it back.

Zhang Heng estimated that this guy was likely to have secretly photographed someone in Unit 2 and Building 5 before, and he had a little impression of the residents of that building, but he didn't dare to say this kind of thing.

Zhang Heng also pretended not to hear his extraneous sound, and watched the young man in charge of monitoring tune up last night's video, and the latter hesitated, "Actually, this video is useless." ”

"Why do you say that?"

"You know the mentally ill college student who lives in this building, and in the morning they called the police to have a thief in the house, and the police came and checked the video."

"Did they find anything?"

"No, the police estimated that the thief went around the blind corner of the side camera and climbed upstairs from there, but fortunately, he didn't lose anything in the end, and the police didn't investigate further."

Zhang Heng raised his eyebrows, noncommittal, he clicked fast forward, finished the video, before 12 o'clock, there were still some people in and out of Unit 2 and Building 5, but after 12 o'clock, most of the people basically slept, only one man who was socializing outside, and walked into the building drunk at about 1 o'clock, but no one else came out of it until dawn.

"What about the video footage at the entrance and exit of the community?" Zhang Heng asked again.

"Do you want the entrances and exits? Whoever picks up your phone and stuffs it in your pocket can't tell. The young man muttered, looking a little reluctant, but now the situation is stronger than others, and when he saw Zhang Heng looking over, he could only honestly find the folder at the entrance and exit.

Zhang Heng spent another ten minutes, fast forward to finish watching the video of the entrance, and the camera outside the unit door, similar to Zhang Heng over the wall will not be recorded by the camera outside the unit door, and the video of the entrance and exit, as long as there are vehicles in and out, will be recorded.

However, Zhang Heng was not able to find the red fit of the college student's home in it.

Could it be that three people just evaporated from the world for one night?

Zhang Heng thought for a while and asked the young man, "Did anyone else come to the monitoring room before the police came to you?" ”

"No...... bar. The young man scratched his head.

Zhang Heng heard a hint of hesitation from his words, "What do you mean?" ”

"Well, I think about what you said, before the police came to me, I received a call from the leader, asking me to send him something, I left the monitoring room for about 10 minutes, but I locked the door when I left, etc., does this have anything to do with you losing your phone? Are you here to inquire about college students' homes, or are you looking for your phone? ”

“…………”

Zhang Heng understood, it seems that he is a step late, eighty percent of the video in the monitoring room has been technically processed, this kind of thing is difficult to see with the naked eye as long as the other party's technology is passed, since the college student's family has declared that they have not lost anything, the police are estimated to not bother to verify the authenticity.

Zhang Heng has realized that his call to the police in the morning may be a little hasty, not only did he force the college student's family to show its original form, but there was a suspicion of startling the snake, mainly at that time he didn't know what the situation of the college student's family was, and he didn't expect that the other party would have a master in modifying monitoring, you must know that the police arrived at the community and came to the monitoring room to check the video, and there should not be too much time in between.

Being able to process the video so quickly shows that the other party has strong technical ability.

Although Zhang Heng also has a lv2 geek skill, he has not been trained in this area, and he thinks that he can't do it, but this matter is not completely useless, at least he now knows that the leaders in the young people's mouths are likely to have been replaced by the same as the college students' families.

Zhang Heng asked the name of his leader from the young man, copied the two altered videos with a USB flash drive, and then warned the latter, "Don't tell anyone else about my visit to the monitoring room." ”

"Don't worry, I won't think I've been working too long, if you come to the monitoring room, it's me who loses your job." The young man patted his chest and said, and then an embarrassed smile appeared on his face, "And that, you see I'm so cooperative, isn't it ...... about the small video?"

"I'm not going to tell anyone about the video, but you'd better stop doing it, and, remember, keep your mouth shut when you're drinking." Zhang Heng warned again.

…………

Although it was unfavorable to be a teacher, Zhang Heng was not too discouraged.

He knew that what he had to deal with this time was not simple, and it could be seen from what happened to the college students, they should have been in the human world for a while, they were familiar with the rules of the human world, and they were even more proficient in using them than humans.

Zhang Heng can imagine how desperate the previous college students were, he found that his family was dropped, but no one believed him at all, everyone around him would only think that his mental illness was more serious, so that no one would believe his words anymore, and he had to eat and sleep with these creatures from nowhere every day, living under the same roof.

Even if you are a normal person, it is estimated that you will be really depressed after a while.

However, Zhang Heng can find some things from it, no matter what means the other party uses to drop a big living person, obviously this process is not easy for them, otherwise, they don't have to send college students to a mental hospital, and they have waited until now to completely solve this hidden danger.

There are also the three children in the news before, and now it seems that the accidental drowning incident must be related to these things.

The question is, why did they kill those three children?

If it is only because their identities are found out that it is unreasonable to do this, since they can send college students to mental hospitals as adults, they must have other means to control the three children.

It can also be seen from their way of acting that they have always been cautious, living in the place of their original owners after dropping their bags, trying to integrate into the human world and trying not to attract the attention of others.

And what happened on the river beach has become the hottest news in recent times, which obviously does not conform to their rules, and the college student, if he is so afraid of these things, why should he take such a big risk to run out of his house and come to the river beach.

What the hell was he doing there the night they met?
