Today, Shallow Water made a few more good dishes.

"Master, the food is too rich, just make it simple next time." Xiao Yao said embarrassedly.

"It's just, it's better to keep it simple next time." Teacher Yao said, "Usually when I'm at home, you're all-"

"What's wrong?" Shallow Water smiled and said, "I like this kid when I look at it, and I love to make it for him to eat, how about it?" ”

"Master, don't ...... like this" Xiao Yao was a little embarrassed.

"Hey, you go on, I just said." Shallow Water looked at Xiao Yao with a smile.

"It's gone," Xiao Yao said: "I went out with a bunch of notebooks and spilled them all over the ground, and I happened to be bumped into by Yu Luying, so she squatted down to help me pick it up, and I felt that this girl was very kind at that time." ”

"That's kindness?" Teacher Yao said.

"Anyway, I was deeply impressed," Xiao Yao recalled, "and from then on, they became friends." ”

"Uh-huh." Shallow water said.

"Later, it was the time of the Poetry Society," Xiao Yao said: "At that time, she sat alone by the window, and she didn't talk to other classmates, just like that, holding her cheeks and looking outside." ”

Xiao Yao put on a cheek support pose: "It's quiet, and it's lonely." ”

"Let me guess, and you'll sit down." Shallow Water stroked his palms and smiled.

"After all, it's just the two of us in the same class." Xiao Yao explained.

"Very good." Shallow water said.

"Later, when it was time to exchange poems, Yu Luying's poem left a deep impression on me, called "Fallen Angel"."

"Fallen Angel." Shallow water repeats the name.

"The fallen angel is firmly locked," Xiao Yao began the poem recitation with his own words: "Broken wings by prejudice, gasping in the darkness of despair, do you know her name?" Eventually, she will be driven to the other side of oblivion, to return to nothingness. No, it's not! The Requiem will turn into a cry and tear off the mask of the hypocrite......"

"You've memorized it all?" Teacher Yao commented: "This crooked poem doesn't sound like something written by a religious child at home. ”

"It seems that good students also have a rebellious side in their hearts, and you, the head teacher, can take good care of them." Shallow water said.

"Finished eating, right? Gone, went to school. Teacher Yao took Xiao Yao's arm and stood up.

"I'll wash the dishes."

"You can pull it down, don't smash my bowl again!"

"Yao Qi," shallow water called, "I'm sure this kid won't do anything bad, you can help him check the surveillance tomorrow." ”

"I see." Teacher Yao sighed.

The make-up class that night went quite smoothly, and Teacher Yao even began to wonder how Xiao Yao could have done so badly in the exam before.

"If you continue like this, you don't have to just pass the grade." Teacher Yao said.

-- Dividing line --

During the lunch break the next day, Mr. Yao finally opened the door of the security monitoring room for Xiao Yao.

"The people from the security department have gone to dinner," Teacher Yao glanced at his watch, "There isn't a lot of time, it's best before they come back-"

"How do you use this thing?" Xiao Yao reached out and took the mechanical mouse.

"I will, I will," Xiao Xiong snatched the mouse from Xiao Yao's hand and sat on the chair: "Time period, what time does physical education class start?" And then to the physical examination, about two hours interval, right? ”

"Look carefully, since you want to do it, you have to find out something." Teacher Yao admonished.

"Two hours, four times the speed, half an hour to finish," the bear said confidently, "the two of us staring together." ”

"I'll help you keep an eye on the wind." Teacher Yao said.

Half an hour later.

"How?" Xiao Xiong rubbed his sour eyes: "Is there someone from your class who is not in and out of the classroom?" ”

"It should ...... No? ”

"That's the inner ghost," Xiao Xiong analyzed, "among them, the last group of people to leave the classroom, and the first to return to the classroom, are the most suspicious." ”

"Write down the names of these people and judge them one by one." Xiao Yao said.

"First of all, I will ask you old classmates if they agree." The bear shrugged his shoulders.

"It's hard to ...... estimates"

"No, wait! Here, 64 points...... Around 37 seconds, rewind ......" the bear excitedly operated: "Yes, right here, did you see it?" ”

"See what?" Xiao Yao asked inexplicably.

"Look again, look carefully!"

"Something seems to have flashed by, quickly?"

"How does this software set the frame-by-frame playback ......? Oh, here. The bear dragged the progress bar.

"He deserves to be the representative of your class's computer class." Xiao Yao sighed sincerely.

"Play from 34 seconds, 24 frames per second, look carefully."

Both held their breath.

"It's coming!" The bear yelled and tapped the space hard.

"...... this?" After seeing the picture on the screen clearly, Xiao Yao's blood was coagulated.

The bear was also pale, magnifying the picture.

On the bumper mirror at the corner of the corridor, the silhouette of a person is reflected.

The Mediterranean hairstyle, the bulging belly, the medium build, and his habitual movements...... It's all very familiar.

"No, it's ......" the bear let out a shuddering sound, then adjusted a few frames forward, then a few more frames back.

It can be clearly seen that the figure that resembles Teacher Yao has walked through this mirror......

Maybe it's the angle of the camera, and it doesn't capture the person himself.

"Mirror, why is it a mirror again, do you ......" Xiao Yao touched his chin and whispered to himself.

"That's not right," Xiao Xiong lowered his voice and glanced out the door: "Didn't Lao Yao say that he had been hanging down during the physical examination?" ”

"It's not far upstairs and downstairs, and it's not strange to come up, maybe he forgot." Otherwise, why would he arrange for us to watch the surveillance? ”

"Forgot? He had come up, at least to testify about the entry and exit of people here for a while, but he chose not to say a word, forgetting that he couldn't make sense. In my opinion, he just did something to monitor for us to see, but unfortunately he didn't deal with the mirror. ”

"With such a vague shadow, it doesn't have to be Teacher Yao." Xiao Yao whispered.

"Who else but him? They can't be twins, right? He was present at the scene at the time of the crime and lied to us afterwards, which is called, this is called a major suspicion. ”

"Are you still going to judge the teacher?"

"How is that possible, you must not let him know what we have found now, you have to be strict. Now that we have the right direction of investigation, we don't need to look for a needle in a haystack, and the next step is to think about ......."

"It's almost time, are you two okay?" At this moment, Mr. Yao pushed the door and came in: "Did you find anything?" ”
