Sleepless nights......

The wake-up bell pierced the sky in the night, some students walked through the snow and chatted, Song Jinnian rubbed his sleepy eyebrows, and there was a little light outside the window.

Still nothing was found.

Irritable, he picked up the teacup and put it in his mouth, but he drank it empty, and he had no choice but to pick up the small teapot, but he didn't drop half a drop after pouring it for a while, and he looked at the gradually brighter sky, and the irritability in his heart was even worse.

One night, all night, I don't know how many times I watched it repeatedly, but it was still blank and annoying, and Song Jinnian felt that he didn't have it for the first time.

.

Annoyancedly kicked the office chair, which slammed into the wall, bounced back and whirled just a few centimeters away from him.

I hurriedly brewed a cup of instant coffee, grabbed my coat from the sofa and left the office.

Today's holiday, he still has time to waste!

"Damn,!"

As soon as Song Jinnian entered the classroom, Lu Yan burst out coldly.

Yan Mo raised his head from the book and couldn't help but be stunned when he saw someone coming, "Sick?" Bloodshot eyes. ”

"I didn't sleep all night." Song Jinnian propped his head and closed his eyes to recuperate.

"Why are you going?"

"Look at the surveillance."

"Oh," Yan Mo turned back to read the book, and said unhurriedly, "For her?" ”

Song Jinnian didn't deny or admit it, just sighed, opened his bloodshot eyes, and looked at him, "Together?" ”

Yan Mo's black eyes stared at him for a while, his face was full of sleepiness, and he finally couldn't bear it, and nodded, "Okay." ”

"I want it too, I want it too." Even if he didn't know anything, Lu Yan was still very righteous and stuck a knife in his brother's ribs.

As soon as the morning was over, the three of them went straight to the student union office.

"This is what I have screened."

Open the folder, click play, the characters in the surveillance suddenly come alive, and the three of them sat together, staring intently at the picture played on the computer.

An hour later, nothing was found.

Two hours later, my eyes were a little tired, but I still didn't find anything.

Three hours later, it was still the same.

Three hours of intense staring at a computer screen had overloaded the nerves in the brain, and the eyes were even more dry.

Song Jinnian pinched his head, and his tiredness was even more obvious.

"What to drink?" He asked, getting up and walking inside.

"Coffee."

"Coffee."

The two of them didn't look back, always staring at the computer screen.

And it just so happened that he was going to make coffee too.

Because it is instant coffee, the aroma wafts out from the back quickly.

Song Jinnian put two cups of coffee on the table, stretched out his hand and paused, "Rest for a while." ”

The two of them loosened their necks and got up.

They stood side by side by the window, the hot coffee in their hands rising from the white mist, and the aroma came to their noses.

Outside the window, it snowed again.

Yan Mo took a sip and licked his lips, "The coffee I brew every year is still so delicious." ”

"Get out."

"Every year......

"Get out."

"Year ......"

"Get out."

"Here you go again." Lu Yan was speechless, such a bickering game has lasted for nearly three years, and he is not tired!

"Yan Mo opened his head." Song Jinnian said lightly, and took another sip of coffee, as if this matter really had nothing to do with him.

Fifty steps of laughter and a hundred steps, Lu Yan slandered in his heart.

"Year ......"

"Get out." Song Jinnian still mercilessly scolded back before he said the next word.

Yan Mo was not angry, and after playing enough, he changed back to the normal name.

The snow tends to get heavier and heavier.

"Why don't you go back first?" While the snow is still normal, it is not so difficult to go back.

"No problem." Yan Mo finished the last sip of coffee and stuffed the cup into Song Jinnian's hand, "You wash the cup." ”

After saying that, he turned around and went back to the computer.

Lu Yan also hurriedly poured the last sip, and with a smile, he also wanted to stuff the cup into Song Jinnian's hand, but suddenly a cold eye swept over, and he took all the cups into his arms, and said as he walked: "I'll wash I'll wash." ”

At the end of the break, they sat around again, and the computer was still playing the footage they had seen half an hour earlier.

"Tsk, I can't see any clues, but I always feel that something is strange." Lu Yan muttered casually, but it made the eyes of the other two deepen.

It's this feeling, I know that something is wrong, but I can't see the point that is wrong.

Annoying!

"Wait a minute," Yan Mo suddenly said and pointed to the progress bar, "Go back a bit." ”

Song Jinnian dragged the mouse and moved it back for a minute.

The picture stays in the empty physics office, and the time at the top is displayed at 15:45:32 on October 16, which happens to be the day Chu Xiaoxiao was pranked.

Half a minute later, a girl appeared in the picture, with half of her face wrapped around the collar of a black down jacket, holding a homework book in her hand, walking quickly through the first desk and walking straight down the aisle, obviously to hand in her homework.

15:46:14,The girl's footsteps suddenly slowed down by half a beat.,The stunned on her face flashed.,The footsteps paused there.,It took nearly a minute before it started moving again.,Ben went straight to the aisle and walked straight to her feet.,Moved a few steps to the right.,Leaned over and put the notebook on the opposite side.。

"Obviously, you can easily put down your homework by taking a few more steps, why do you turn to the side in advance and put your homework on the opposite side in this posture, according to normal people, they won't choose this way, right?" Lu Yan turned his head to look at the two people who were frowning, and expressed his doubts.

"Who knows." Song Jinnian stared at the screen for a moment, and naturally remembered what Lu Yan said.

"Maybe she's been practicing dance lately." Yan Mo said lightly.

"Huh?" Song Jinnian and Yan Mo both looked at him in unison, what kind of digression is this?

"So it might just be a move in her dance."

“……”

I don't understand your cold humor!

At 15:50:00, the girl came out of the office.

Song Jinnian pressed the pause button and knocked on the table twice, "When she went out, it didn't seem natural to walk." ”

Yan Mo took a look back, "Interested in looking for monitoring?" ”

"It seems that the computer connected to the monitor of the physics department is installed inside, and the thing is quite hidden, in a small corner of the waste area, and you can't really find it if you don't pay attention."

"How do you know? Punished? ”

Lu Yan scratched his head embarrassedly, "Once I walked without looking at the road, I bumped into it directly." ”

“……”

What follows are some dispensable surveillance screens, and when I finish watching it again, the wall clock on the wall has already sounded, and the time is exactly six o'clock.

Outside the window, the snow was covered, and the pure white world was covered with a veil in the night.

"You guys go back first." Song Jinnian stretched, opened the window and reached out, "The snow has stopped." ”

"You're not going back?"

"Hmm."

"No, brother, life matters."

"I'm measured."

"Let's go have a meal together." Yan Mo picked up his coat and put it on, and threw Song Jinnian over.

Song Jinnian raised his hand to catch it and shook his head, "No, I'll go to my uncle's place later, and I can cook noodles by myself." ”

"Oh."

"I forgot that the principal has an apartment in the school, and if you go, you won't starve to death anyway." Lu Yan pulled the zipper and pushed Yan Mo out of the door.

He sat back in front of the computer and began to play the surveillance footage over and over again, but this time it was the girl in a black puffer jacket and a homework book in her hand.
