Although he felt strange, Zhang Yu didn't say anything and continued to perform.

"That's true. At least I didn't find it before I went to bed."

What's more, this letter was found on my quilt directly. If it had been put on before I fell asleep, how could I not see it?

"Get the surveillance camera in the apartment. I want to see who sneaked in last night?"

Zhang Yu glanced at Hu Jieyu, but the latter didn't respond at all, so he couldn't help saying.

Hu Jieyu didn't say anything. He just did it according to Zhang Yu's instructions. The camera has been tuned out and the surveillance video has been put on the computer screen.

"Except for two periods when there was a brief power outage in the apartment building, everything was normal at other times."

Hu Jieyu leaned over and knocked on the computer again. Then he said that Zhang Yu took a quick look and found that one of the blackouts was at 12 o'clock in the evening and the other at 3 o'clock.

"What happened to these two blackouts?"

Zhang Yu just felt very strange, so he asked a lot, but went to see Hu Jieyu's normal face.

"These two blackout times are specially set by me, and each blackout time only lasts for five seconds at most."

In five seconds, it's almost impossible to do anything, so these two blackouts won't have too serious consequences.

"These two blackouts are specially set by me to ensure the safety of the apartment building. In addition to the monitoring equipment, the access control system under the apartment building will be powered on 24 hours, and the power grid outside the window will double the power during the five second blackout."

In other words, even if the power is really cut off, it will not cause too serious consequences.

"But, generally speaking, it should be 24 hours a day?"

Shen Mengjing also put forward his conjecture, but Hu Jieyu always understated it.

"If the system is set up well, if the power is not cut off, the system will not be able to self check during the short dwell time. If it is suddenly interrupted in the daytime, it will cause more serious consequences."

“…… Generally speaking, these two power outages will not cause much impact, and they were originally set, so it can be basically ruled out that the other party used these two time periods to sneak in. "

Except for these two breakpoints, there is no doubt in other time periods. "And other security measures of the apartment are in good operation. No one sneaked in last night. If this letter has been put up since before going to bed, that is to say, it was put up by the people we live in."

If this goal is transferred to the people who lived in this apartment building last night, it will be too simple. For privacy reasons, surveillance cameras will not be installed in the apartment building. In this case, it is an easy task for anyone to put a letter in someone's room, especially on the bed.

"Who is it? Do such a boring thing? "

Shen Mengjing a little angry shouts.

There were only four people at the scene, Zhang Yu, Shen Mengjing, Hu Jieyu and Wang Zijie. Four people looked at each other, "this is really not what we do."

Wang Zijie took the lead in speaking, but was glared by Shen Mengjing. "You still have the face to say. You are the one who likes to joke most

Wang Zijie is really aggrieved now. He is not a person who doesn't know what to do. How can this kind of thing be done?

"If you don't believe it, I can't do it anyway." Wang Zijie's own temper also came up, so he and Shen Mengjing began to hold each other's breath. Zhang Yu and Hu Jieyu could only persuade each other.

Finally, the contradiction between the two people was solved.

"Well, let's think about it now. What's going on?"

All of a sudden, a letter was found on the bed. Everyone had no idea, and Shen Mengjing was a little nervous. So Hu Jieyu suggested that we should have a rest.

In addition, if we look for possible clues, we can think for ourselves, and we may miss something.

After everyone disbanded, Hu Jieyu immediately pulled Zhang Yu, then dragged him to a room on the edge of the corridor and locked the door. Zhang Yu found that there were many computers and servers in the room. It seems that this is Hu Jieyu's hometown.

"I decided to send Shen Mengjing abroad."

Hu Jieyu frowned and looked at Zhang Yu. It seemed that he made the decision very hard.

Zhang Yu nodded and didn't have much opinion on it. From this point of view, it seems to be the best way.

"Of course, it's impossible for me to let Shen Mengjing go abroad alone. I'll go out with him. In addition, I'll find a bodyguard for myself. In a word, to ensure the safety of both of us, you can take over with Wang Zijie at home, and let me know as soon as you have any news."Zhang Yu thought for a while, and finally agreed with this method and nodded.

"In addition, when you are abroad, you should also pay attention to let Shen Mengjing undergo surgery."

Hu Jieyu nodded cautiously and said he had found a suitable hospital.

"I know this expert before. You can rest assured that all my problems can be solved. You just need to ensure the safety of the domestic side."

After the discussion, they went out of the room. Then they saw Shen Mengjing standing at the door of the room, looking suspiciously at the two people who went out of the room.

"You two don't have ghosts in mind, do you? Why do you want to get together to discuss?"

In principle, the relationship between Zhang Yu and Hu Jieyu is not so good. In contrast, they should discuss with Wang Zijie.

"That's right. I see you two are talking about it. You don't want to do anything bad."

"Where do you think you are? Are the two of us like this? "

Zhang Yu said innocently, glanced at Wang Zijie, and then laughed with Hu Jieyu.

"I think you two have ghosts in your hearts!"

Wang Zijie snorted, then turned around and left. Until dinner, the four talents got together again.

"In fact, I have thought about many things before, but I always feel that maybe the four of us didn't put the letter on it."

Shen Mengjing said, pointing to the ceiling of the roof.
