"Yes, my name is Annie Lin, and I am a seventh-grade music teacher." Annie Lin answered.
"I am Li Le, a fourth grade biology teacher."
"I am Niu Zishan, the head teacher of Class 7, Grade 6."
The three teachers answered.
Ye Feifei carefully observed the three teachers and saw that they had similar dressing styles and similar ages. She was even more sure that what was written in the information was correct.
"Don't worry, teachers. You are with us now and you will not be in danger for the time being." Catherine saw the hands of the three teachers trembling and took the initiative to comfort them.
The three teachers nodded doubtfully.
"Don't be afraid, my people are outside." Ye Feifei pointed to the door.
The three teachers followed Ye Feifei's fingers and saw several men in black suits, and immediately knew that they were Ye Feifei's bodyguards.
With the bodyguard in hand, they finally breathed a sigh of relief. Their hands that were shaking just now returned to normal. The three of them subconsciously turned back to find pure water to drink.
Ye Feifei watched them drinking water and then came to the surveillance room. She said to the security guard in the surveillance room: "How is it? Did you see any difference in the surveillance video?"
The security guard nodded and replied nervously: "We don't know what happened, but the surveillance near the accident was destroyed. We check it every day. I don't know why it happened like this this time. The principal knew it would happen.
Fire us!"
"Don't be nervous. First find the destroyed surveillance channels. Let's take a look at the pictures before they were destroyed." Ye Feifei patted the security guard on the shoulder.
The security guard nodded honestly, and then turned on the surveillance camera as Ye Feifei said.
Soon, Ye Feifei saw the side of the swimming pool.
Before the surveillance was destroyed, there was no one at the pool.
There have been a series of murders in the school. For the safety of the students, the teachers will not arrange any more activity classes for these two days.
Ye Feifei knew this.
"There's nothing unusual here. And here, look!" the security guard said and opened another passage, which was the area where the hanged Teacher Tian passed.
The surveillance there was not modified, but what Ye Feifei and the others saw was that Teacher Tian walked into the classroom by himself, and then hung himself in the classroom with a rope.
"It's nothing special. It's very similar to other teachers when they have accidents." Lin Anni said, her heart ached because she was afraid.
"No, there are different places." Catherine, who had a detective mind, pointed to a piece of ground and said to Ye Feifei: "Look here, when she walks, she always has paper scraps on her body. This is very abnormal."
"Yes, I remembered that the corridor was very clean at that time!" Teacher Li Le touched her chin and replied. She knew that Teacher Tian was in trouble, so she walked through that section to see. But the floor of the corridor was strangely wet at that time.
It's clean, she hasn't seen any scraps of paper.
When Ye Feifei heard Catherine talking to Teacher Li Le, she narrowed her eyes slightly and said thoughtfully: "It seems that someone handled the paper scraps on the ground at that time. Then they erased the video of handling the paper scraps."
"What? Can it still be erased? Then... is he... a master, a master of black computer technology?" Lin Anni said and glanced at Li Le, as if a suspect appeared in her mind.
"Yes, of course. Are any of the three teachers suspicious?" Ye Feifei looked at Lin Anni.
Lin Anni nodded slowly and replied: "Yes, one of the people we know is suspected."
