Chu Xiaoxiao had already chosen it before Qin Yue had time to re-swing it, and she really felt that it was very troublesome to swing around, so she simply picked one casually.

Qin Yue's eyes lit up when she saw the drink in her hand, "Senior sister, it turns out that we all like to drink this, what a coincidence, this is still my pick, I'll help you open it." ”

"No, no, I'll do it myself." As soon as he said that, the bottle cap fell into his hand

“……”

There's no way, I've been single for so many years, and I can't really say anything about it.

"How the surveillance flashed and flashed." Qin Yue only glanced at it, and he felt dizzy, and he didn't know how they had looked at it for so long.

"Lightning." Yan Mo gave him a seat, and he waved his hand to refuse, how embarrassing was this.

Yan Mo raised his hand, and he was carried to the chair like a chicken, he moved uncomfortably, and wanted to get up, but was pressed back, "Sit here to help me block radiation." ”

I don't care about you!

He doesn't like the hot and coaxy chairs that others have sat on!

But the senior sister is here, he is still obedient, and he wants to leave a good impression on the senior sister.

"Is she talking?" Qin Yue leaned in to take a closer look, "Her facial muscles seem to be moving." ”

Song Jinnian put the picture to the maximum, and sure enough, he saw the slight changes on the girl's face.

"Really!" Chu Xiaoxiao's eyes widened, "The junior brother is very good!" ”

Qin Yue was praised by his senior sister, and he was so happy that he didn't dare to look at her, "It's okay." ”

"Does this prove that Yan Mo said earlier that it was two people?" Lu Yan's heart was surging, and she was suddenly very motivated, "The female student hurriedly handed in her homework, and suddenly saw her friend or classmate stealing the test questions, she was stunned and questioned for a while, the person who stole the question knew that the female student did not do well in physics, and took this as a starting point to fool the female student into embarrassment, and the female student was reluctant to give up the temptation, and decided to go along with the temptation, when she didn't see anything out of the classroom, she protected each other as witnesses after the incident. ”

"Ah, is it okay for each other to be witnesses?"

"That's better than having only air as a witness to make people believe, unfortunate boy."

"Brother-in-law, I think this title is too ugly, how about calling it an ex-brother-in-law?"

"I shut up, I don't speak, I'm going to drink water." Lu Yan made a gesture of sealing his mouth and slipped away.

The monitoring came to the end again, and Song Jinnian returned the progress bar again, and tried a few times before putting it on that screen.

Chu Xiaoxiao sighed, he pulled the progress bar forward a little more, and another girl appeared in the surveillance, she held her face and looked at it carefully for a while, "I said why is she so familiar, it turns out that I saw her when I went to the physics department that day." ”

"What's wrong?"

"It's okay, just be curious to take a look, anyway, it's not a few minutes away from the surveillance we want to see, so let's take a short break."

"Fault!"

"You're swearing again!"

"Senior sister, you can rest, I'll help you watch."

"Then I'll go rest, you can help me watch." Yan Mo patted him on the head, and without waiting for him to agree, he fell on the sofa and closed his eyes.

Qin Yue secretly rolled his eyes at him, moved his chair, and leaned on the table to watch.

Ten minutes later, I finished reading it again, and I didn't seem to see anything except what I said earlier, except for ......

"They put their homework in the same place."

"Who?"

"The senior sister that Senior Sister Xiao said, and the senior sister who appeared later." Qin Yue pulled the progress bar back and forth to show them, and it was indeed so.

"From this, it can be determined that they are classmates, and the senior sister in front should be the representative of the physics class, because she came in with a stack of homework books, probably when the second class ended, she received her homework and then sent it to the physics department."

"But that doesn't seem to mean anything."

"It looks like it's true, but it always feels a little connected." Qin Yue leaned back in his chair, stared at the flashing screen with wide eyes, and suddenly smiled weirdly, "Found it." ”

"What, what, what?" Chu Xiaoxiao babbled, attracting the two people who were resting.

"What's wrong?" Yan Mo asked.

Song Jinnian pointed at Qin Yue, "Ask him." ”

Yan Mo looked down at him again and asked, "What's wrong?" ”

"I'll zoom in to show you." As he spoke, he tinkered with the mouse twice, and the mobile phone pendant exposed by the lightning was clearly visible.

"This is not South Korea...... Even-bar ...... ? The last one is not very real, because she has already felt the murderous gaze cast by Song Jinnian.

As the successor of socialism, she is still very patriotic!

"I remember that the school explicitly forbade taking mobile phones out of the dormitory while on campus, right?" She quickly digressed the subject.

"The leakage of questions was reported after the exam, which shows ......"

"It shows that the person who steals the question directly uses his own mobile phone to take pictures of all the questions." Yan Mo snatched his words, Qin Yue turned his head and gave him a thumbs up.

"Let's see if we can find any traces of using a mobile phone." Song Jinnian said.

The monitoring began to focus on the time period of 15:35:42~15:50:00.

"Flash."

The three of them shouted these three words in unison, and Chu Xiaoxiao and Lu Yan looked at each other, as if they were not in the same world.

"It began to rain at about three o'clock in the afternoon, lightning and thunder, the light in the room is simply not enough to take a clear photo with a mobile phone, if there is no flash, the test questions must be blurry, finally the test questions are close at hand, she must not want to take this risk, then the flash is bound to be used, how to use? Match lightning. ”

"But no matter how careful you are, the advantage will become a flaw."

grabbed the time point and pressed the pause, the surveillance screen was white, to be honest, "It's quite like a ghost movie." ”

Chu Xiaoxiao's words received a few more blank glances.

"Senior sister is not afraid, I will protect you." Qin Yue never forgot his knighthood, but he also received white eyes.

Song Jinnian didn't bother to pay attention to the two children, and said to himself: "Although lightning can hide the flash to a certain extent, the light emitted by the lightning and the light of the mobile phone flash are different after all, the light emitted by the lightning is undoubtedly very powerful and can illuminate the entire sky, but if the lightning center is far away, even if it can illuminate the entire department, but compared to the close flash, especially in a small space where various objects play a role in shading, the light of the flash will obviously be more prominent, so it can be found from the picture." The light that appears somewhere at the very edge of the surveillance is stronger than the picture in the center of the field of view, which can be understood as the light of the lightning superimposed on the light emitted by the flash under certain conditions, so if you look closely, the boundary between light and dark is very clear. ”

"The girl put down her homework and left, how to explain this? If you turn back halfway, you will also be photographed by the surveillance, right? ”

"What if she knows the scope of the department's surveillance?"

"What?"

"She is the representative of the physics class, which means that she will often go in and out of the physics department, as long as she puts more thought into it, it is not impossible to understand the blind spots of the department's monitoring. So it is very likely that after this senior sister went out from the front door, she came to the back door in a circle, through the understanding of the physics department, and avoided the monitoring range to find the physics test questions, because the light in the rainy room was insufficient, so she thought of using lightning to cover the flashing lights, but she killed another senior sister halfway, in order to protect herself, the two made a verbal agreement, one kept it confidential and one shared, so the matter passed the exam unharmed. ”

"Junior brother, you're too powerful."

"It's alright." Qin Yue smiled embarrassedly, Detective Conan was chasing after him all the time.

"So is this a sure culprit?" Chu Xiaoxiao was about to jump up excitedly.

"Nope." The unanimous answer was like a basin of ice water splashed on her face.

"Why?"

"I still have to find someone to testify."

"That's pretty much the target!" She let out a long sigh, "The truth is finally coming out." ”

Song Jinnian turned off the computer, and several people all sat back on the sofa, and the time was displayed as half past four in the afternoon.

"I'll treat you to beef noodles." Chu Xiaoxiao was very grateful for their hard work.

Qin Yue nodded yes when he heard it, Song Jinnian acquiesced, Yan Mo saw that they agreed and agreed, but Lu Yan shook his head, he said that he was going to accompany his girlfriend, and then he was immediately blasted out by the noodle-eating trio.

The holiday ended as scheduled.

As soon as the holiday was closed on Sunday night, Song Jinnian immediately reported the matter, and the school immediately gathered the class teachers in the conference room, but in a minute, the student's name and class number surfaced, and the school leaders had a two-hour interview with the two that night, and the two confessed to the leakage of the physics test questions.

Speaking under the national flag on Monday, the principal made a school-wide report on the criminal acts of the two, and the main offender Chen Hui was expelled from the school and forced to withdraw from the school, and the accomplice Liang Yingying was sentenced to two major probations.

Fortunately, except for Chen Hui and Liang Yingying, the results of this physics exam are not invalid. Although Chu Xiaoxiao really can't get used to the ham sausages and eggs on the physics test papers, she has not become the Dou E of the new era, which can be regarded as filling the unpleasant point in her heart.

In the early morning of October 25, 2014, a leak of test questions officially came to an end.
