[Comprehensive] shadow of light

Really fun things happened.

Although the video at night is not clear, it is not pitch black, and there is an obvious time display in the lower right corner.But at 37:26:47, the time in the lower right corner suddenly jumped to [-]:[-]:[-]!There was no change in the image, the tenth place jumped from three to four in an instant!

Fast-forward to check the video tape, such a difference is easy to skip if you are not careful.She was lucky. At that time, the scene with no movement was so boring. Her eyes would glance at the fast-forwarding time bar from time to time. Maybe she couldn't find anything abnormal when she watched it for the first time.

In other words, there was a full 20, [-] seconds of vacancy, and the camera at the door of the office only served as a decoration.

Mr. Watanabe may have just read it casually, and did not pay attention to the change of time.

It is entirely possible that someone took advantage of that vacancy to enter the office, secretly took out the test paper locked in the cabinet, tampered with it and put it back.

She was considered a suspect because someone witnessed Sato Kanako asking her to help change the answer, and besides her, no one had a motive and there was no alibi.From the perspective of the suspect, it is possible that all the members whose answers were changed.But the base is relatively large, and it takes time to investigate one by one, and there is no guarantee that others will not lie.

In fact, she first considered whether it was Sato Kanako who corrected it herself. After all, Sato's chemistry grades were terrible and she complained about Watanabe every day.However, Ninomiya Saki obviously remembered that Sato left on the bus with the track and field club on Friday afternoon, conducting secret training for the summer competition, and the alibi was perfect.

Ahhh, thinking of Ninomiya Saki here, I think it's really interesting, and such an interesting thing will become boring if I keep it alone.Thinking that Nioh Masaharu should have a part in this matter anyway, he couldn't wait to go to the tennis court to look for him.

But from a distance, I saw a group of teenagers training very seriously, and that kind of seriousness exuded an aura that could not be disturbed. Zhengchou was sending emails to him, and I saw Nioh Masaharu running over automatically after the break up.

Just right.

"Puff~"

Seeing that Nioh was also very afraid that the world would not be chaotic, Ninomiya Saki said with a smile: "A funny thing happened, and it disappeared for 10 minutes, oh, in the video."

Nioh listened to her while drinking from a sports bottle.

Because of the backlight, the outline is particularly obvious. From the Adam's apple down to the collarbone, the lines are clear and beautiful.

Just as he was about to ask, the short break was over, and the two agreed to meet after training.

When Nioh returned to the team, Yagyu just pushed his glasses and he understood what this boring bastard was thinking.

It is said that someone is still a fan of mystery novels?

He whispered: "It is said that 10 minutes of the tape disappeared."

Liu Sheng was startled, and then laughed too.

The training of the main players in the tennis club ends at about six o'clock, and they are not freshmen in the first grade, so they don't need to stay to organize equipment and so on.

While waiting for someone, Ninomiya Saki returned to the monitoring room and watched the video several times.

The position of jumping time was repeatedly fast-forwarded, and finally found a small uneven gray spot in the lower left corner of the 47-minute screen, which is almost invisible to the naked eye, that is, at the corner of the main corridor.

As for what it is, she has not been able to research it clearly yet.

At this time, the sun was setting, and fewer and fewer people stayed in the school, and the guard uncle in the monitoring room also got off work.

Nioh Masaharu came to find Ninomiya Saki as promised, and brought along Yagyu Hiroshi.

Because Liu Sheng repeatedly assured that the melon seeds in his head must be more useful than someone else.And that someone was noncommittal.

Ninomiya Saki first showed the problematic video to Yagyu and Nioh, and then pointed out the little gray dot, saying: "I always feel familiar, but I can't remember it all at once."

"Leave this question aside for now, let's see if the other cameras have captured anything from the first floor to the office," Nioh said.

Call out the videos of several other cameras, just like the camera A at the door of the office, they all jump directly from 37 to 47.

"I'm more concerned about what kind of person they are, who can stop the surveillance at once. Could it be that they hacked into the school system? Will there be such a person in our school?" Liu Sheng crossed his chest with one hand and rested his chin with the other. road.

"Maybe there is such a master..." Niwang said nonsense very casually.However, Yagyu had been with him for some time, and of course he understood that Nioh actually supported his point of view, but he felt a bit upright in his mouth.

Ninomiya Zaji said: "It would be great if there is such a master, so the scope can be narrowed down."

After thinking for a while, she said again: "But it's fine for such a computer expert to directly hack the school's grade system, and then random people on the Internet-meat me, add fuel and vinegar, why come to school in the middle of the night?"

"Maybe it's cooler to wear night clothes." Someone with dyed silver hair, who obviously has a lot of requirements for appearance, started talking nonsense again.

Liu Sheng joined the topic, "Well, I also think night clothes are cooler. You see, Batman's equipment is very awesome blabla..."

Zao Ji was also misled, "Master is handsome, but I like Catwoman more, black leather + red lips + long legs..."

"You look really straight."

"Thank you for the compliment." He rolled his eyes.

In fact, all three of them felt in their hearts that there should be no such person, and the prisoner should use a simpler and more effective method.

"We looked at the cameras from the first floor to the office. Should we also look at the cameras at the school gate?"

The prisoner didn't appear downstairs out of thin air. Whether he climbed over the wall or entered from the front, there were cameras in these places, so there would always be something wrong.

Ninomiya Saki asked him to teach him how to adjust the surveillance before the guard got off work, but he was a little unskilled.Some clumsily tuned out the video of the entrance and the fence, but the camera at the main entrance was at the end of the school, and when there were many people, suddenly a gloved hand stretched out and sprayed the camera into darkness!

In an instant, only the time display remained on the screen.

Nioh and Ninomiya looked at each other, and then they both looked at Yagyu.The three stood up from their chairs at once, and walked towards the door in unison.

Because everyone is not stupid, I must ask the uncle at the porter at this time.

At this time, it was more than seven o'clock, and it was completely dark.

The school building was all pitch-black, and everyone on the playground was gone, and when the wind blew, the leaves rustled, and Lihai University showed a completely different appearance from the daytime.

The hut in front of the school was brightly lit, and the uncle concierge was watching a funny show inside. Some jokes made him laugh out loud and kept patting the table.

Zao Ji knocked on the glass window, but before he noticed her, she knocked again.

The uncle blushed from laughing because he was watching a funny show. When he opened the window, he was still in a good mood and said, "Little girl, why haven't you come home yet? I thought there was no one in the school anymore."

His eyes fell on King Ni and Liu Sheng again, and he said with a smile: "Little girl, this is a date, and it's pretty good, two at a time."

"...uh..." Zao Ji was speechless for a moment.

Who is dating at school, two at a time, how can she be so awesome?If the fans of the school's tennis club find out, they have to tear her to pieces.

But at this time, I can't care about the black line.

She showed the card that Xingyue gave her, "Chairman Xingyue asked me to do something, and the two of them are also helping."

"The concierge has worked hard at night, I have something to ask you. Last Friday, did the camera suddenly go black?" Zao Ji pointed to the camera at the door and asked.

Just now Nioh noticed that this camera is not high at all, as long as the height is not less than 1.7 meters, it can reach its height with enough hands.

"Yeah!" The uncle had an expression of 'how do you know', "The screen suddenly went black in the afternoon. I thought it was because the camera was broken. The old man has never played these things clearly. I still have a smartphone. I can't play clearly."

I'm going to uncle, you are still following the trend...

"There was no one to repair it on Friday afternoon, and someone came over on Saturday morning. I don't know which little bastard used black spray paint to paste the lens! Really!"

Yes!The one who blurred the lens must be the criminal!

There are so many people at that time after school, no one will find out if someone has raised their arms. If you choose a spray paint that is smaller and can be hidden in your hand, raise your arms and spray the lens with your backhand. It only takes a second, and no one will be there at all. Discover!

And no one will come to repair the equipment on Friday, and the earliest is Saturday morning, when the test paper has already been corrected!

It seems that the prisoner did not reform randomly at all, it was definitely carried out in a planned way.

"Then, did anything strange happen that night?" Liu Sheng asked hastily.

"Strange thing..."

"No matter how small it is," Nioh added.

"...Speaking of it, it's not a strange thing." The uncle thought for a while, and said, "It's just that there was a kid who forgot to take his textbook, and hurried over to get it after nine o'clock. Speaking of which, that kid was really careless. I searched for at least 5 minutes, and told me that it might be in the teacher's office. I opened the office door for him and found nothing. Finally, I found it in the classroom, in the drawer of other students! Today's child! "

That's it!

"Then do you remember what that person looked like?" Zao Ji was anxious, a little excited when he asked the key information.

"Sa... I don't really remember this one. I only know that the height is about..." He gestured with his hand, about 1.7 meters, a very common height among boys, "I haven't had a lot of flu recently, he wears a mask, and he Still behind my back, I didn't see clearly."

They didn't ask what the man looked like, and the three of them were a little disappointed.

Soon Nioh added, "Then which class did he go to find textbooks?"

"I remember that the bow tie is the same color as you two. It seems to be group b or c. He was delayed for a long time that day. It happened to be the nine o'clock TV show. Uncle, I was very upset..."

"In my class?"

"In my class?"

Nioh and Ninomiya pointed at themselves at the same time, and Yagyu concluded calmly, "Anyway, it's in one of your classes."

"Huh? What's the matter?" the uncle asked with some vigilance.

With some progress, my mood is soaring, especially because I personally caught it.

Ninomiya Saki smiled and said: "Ah, it's nothing. Teacher Xingyue asked me to ask, and we don't know too well. Thank you, we will go home now."
