As Ye Bai spoke, he wrote down the key points he just mentioned on the white paper.
"After the holiday on Friday, the time for shift change is 22:00 sharp."
"Except for this morning, when all the teachers and students in the school are in place, there are only seven shifts left on Friday, Saturday and Sunday to do this."
"It is conceivable that there is no one in this monitoring room. So the person who did this, wanted to do it without anyone noticing, and also deleted the monitoring, must have bribed two people working in a certain shift. personnel."
Ye Bai was talking to herself and didn't bother to observe the expressions of the staff because she knew it well.
"As you can see from the schedule, their schedule looks like this:
Friday 22:00-6:00: A and B
Saturday 6:00-14:00: C and D
Saturday 14:00-22:00: E and F
Saturday 22:00-6:00: G and H
Sunday 6:00-14:00: A and B
Sunday 14:00-22:00: C and D
Sunday 22:00-6:00: E and F
Monday 6:00-14:00: G and H
Basically every combination has an overlapping point within these two days. "
Ye Bai wrote out the schedule like this, and a lot of the information became clearer.
"Even if someone colluded with the staff in the monitoring room to do this, we still don't know when they did it." Zhan Yi raised his own question. This issue does not seem to be clarified that simply: " Every point is possible, isn’t it?”
"Every point is possible."
Ye Bai agreed with Zhan Yi's statement, but Zhan Yi ignored an important piece of information.
"Then how can you tell who was bribed?"
"Whoever takes over this morning will be the one." Ye Bai put down his pen and looked up at the two staff members who had been paying attention to Ye Bai's analysis: "Do you think I am right?"
"What are you talking about?"
One of them immediately turned dark and very angry: "We have good intentions to help you check the surveillance, but you still slander us like this."
"That is, if you say we did it, you have to provide evidence, otherwise this matter will never end with you."
The two staff members angrily retorted to Ye Bai, but Ye Bai remained calm and seemed not to be affected at all.
Zhan Yi looked at Ye Bai and said nothing, but his eyes showed doubts and confusion.
"The monitoring records from Friday to Sunday have not been deleted, so the only people who can do this are the two who work the night shift, and you who took over this morning."
"Oh, let's talk about it, that's really what happened." Zhan Yi felt that he had really seen it. He didn't expect that Ye Bai's analysis would really shorten the scope.
"Since you said there are two groups of suspects, why do you think it must be us?"
The two staff members still looked indignant, feeling that they had been wronged and that Ye Bai had deliberately framed them.
"There must be evidence for what we say, otherwise we will definitely file a complaint with the principal."
"go!"
Ye Bai still looked very indifferent and said calmly: "Tell the principal how you took advantage of your position to harm students?"
"What are you talking about?" The expressions of the two people became even worse. Looking at Ye Bai's look as if he was holding a lot of evidence in his hands, it really made people feel a little frightened.
"I can tell it's you, so I have my reasons. If you don't admit it, do you think you've wiped your butt clean?"
Ye Bai sneered, looking at them as if he wanted to see through them all.
