After coming back from Yunnan, they are about to enter the third year of high school next semester, and they began to make up for the hard work, and the quasi-high school junior party does not deserve to have a summer vacation, and it is better than the usual class that they do not study on their own in the morning and evening.

Class at eight o'clock, when Jiang Xin entered the classroom at 7:56 to record attendance, Han Yi and Huang Cancan did not arrive.

At ten o'clock, two classes passed, and Han Yi helped Huang Cancan to come in from outside.

Jiang Xin opened the attendance book and went over, so open that he needed to sign it.

Han Yi didn't even look at her, and casually grabbed a pen and signed her name.

Huang Cancan sat in an awkward position, looking like his injured foot was not healed, took the attendance book, raised his head and gave Jiang Xin a big smile, "I'm sorry Jiang Xin, my foot hasn't healed yet, Han Yi has to accompany me to the school hospital for medicine." ”

Jiang Xin glanced at the two names listed side by side in the column of the attendance book, and a smile of unknown meaning appeared in his eyes.

After school at half past five in the afternoon, everyone in the class went home, Jiang Xin stayed in the classroom, wrote the performance report of the six-person team in the summer vacation practice on the school, and finally determined the ABCD level according to everyone's performance.

A few minutes later, the last part was written, and she was about to submit it to the head teacher when her phone rang.

Out of the corner of Jiang Xin's eyes, he glanced at Huang Cancan, who was slowly sorting out his schoolbag, and clicked to answer.

"Teacher Wang." Class 9 class teacher.

"Okay, I'll be right over."

End of call.

Huang Cancan, who had just pulled up his schoolbag and stood up slowly, watched Jiang Xin walk out of the classroom.

Jiang Xin's Xuegou was lying quietly on her desktop, emitting a soft blue light, and the screen had not yet been locked.

At this time, everyone was gone, and she was the only one in the classroom.

The next day, the whole class arrived. Jiang Xin ran to the podium with a anxious face, "Which of you touched me yesterday?"

Everyone looked at each other and shook their heads to indicate that they didn't know.

Xia Yue, a member of the Literature and Art Committee, stood up and asked, "What's wrong with your Xuegou?" Could it be that the homework is lost?

Jiang Xin frowned tightly, "The summer vacation practice report I wrote was tampered with. ”

Li Qi pushed his rimless glasses and stood up, "Our summer vacation practice? What does it mean to have been tampered with?"

Jiang Xin: "The grade I gave everyone has been changed."

Liu Xia kicked the chair away, "What does it mean to be changed?" Liu Xia's performance in practice this time is very good, and he feels that he can at least get a B grade, and it is normal for him to react so much.

"Han Yi and Huang Cancan have become A-class, and the other six people have all become D-class."

……

Divine polarization.

Xie Ran reacted quickly this time, "I'll go, who did this, it's obvious that the six of us are being." ”

Liu Xia shouted, "Only Han Yi and Huang Cancan are the most changed, and the two of them are the most suspicious!" ”

Li Qi calmly analyzed, "If it were you, would the change of grades leave such obvious evidence for others?"

Everyone fell silent.

Huang Cancan opened his mouth at this time, so aggrieved that he was about to cry, "It's not me, I have no reason to do this, it's not Han Yi, I believe him." ”

Everyone saw Huang Cancan's aggrieved and weak appearance, and they all stood on her side, speaking for her and comforting her.

Jiang Xin bent his fingers and knocked on the table, with a serious expression, "Listen, I wrote a report in the classroom yesterday, and that person must be from our class." This matter is very important, and the practical performance will affect the evaluation of scholarships and grants to a certain extent. So, please come to me before tomorrow, and this matter will end as if it didn't happen. If you don't come to me tomorrow, you will bear the consequences. ”

A sentence at your own risk and carries a lot of weight. Class 9 is the best class in the same grade, but it is not only a matter of good grades, but also good conduct.

Doing such a thing is obviously a touching character with IQ arrears, and Class 9 will definitely not be able to stay.

For the whole day, the class was privately deducing who that person was. The top students are very interested in such "case" reasoning.

Conan said that there is only one truth. Sherlock Holmes also said that if all the impossible is excluded, the remaining one, even if it is incredible, is also a fact.

However, after everyone extrapolated and excluded the 36 students in the class one by one, there was not an incredible fact left! Those two big cheats!

At seven o'clock the next day, Class 9 was full, and the teachers who passed by and the students who lived in other classes saw it, and they wondered, is Class 9 crazy, and they don't go to early reading, so early.

A teacher mentioned it in the office, and Wang Xin, the ninth class teacher, had an expression that everything was under my control, took a sip of tea and said slowly, "Today, there is a drama to watch and melons to eat, of course I have to come early." ”

Another teacher patted his head, "I said, Lao Wang, why did you come out of the sun in the west today, so early." Is there something wrong with feelings? Don't forget to tell everyone to have fun later. ”

……

Nine classes.

Jiang Xin stepped into the classroom on time at eight o'clock. Here she came, here she came.

A group of classmates with dark circles under their eyes seemed to have taken brain-sobering medicine, and they came to their senses in a second.

Watching Jiang Xin take it out and learn from it, he put the shoulder bag into the belly of the table.

watched Jiang Xin slowly swing onto the podium, judging her on the podium yesterday.

Everyone suddenly discovered that something was wrong with Jiang Xin yesterday, and her emotions were too obvious, unlike her.

Jiang Xin rolled up the cuffs of his shirt, clicked a few times on the school, and connected to the multimedia equipment in the classroom.

The projected image, everyone thinks that it is a system and not a system.

Doubts were voiced.

Jiang Xin swept over everyone, making sure that no one was there, and there was an inevitable luster in his eyes, "This is and Xue Gou is right." It's just that he has been officially authorized to have background permissions and learns from it. ”

"Wow, it's official, it's so strong!"

"Jiang Xin, how did you do it!"

Jiang Xin tilted his head and thought about it for a moment, "Oh, did I say that this thing was developed by my father's company?"

??！

Is it really good that you only tell us about this kind of thing now?

Everyone who was caught off guard by the show was shocked and couldn't say anything.

Jiang Xin lowered his head and explained, "Every machine and Xuegou will require real-name authentication when consumers get it, and there are everyone's fingerprints in it, you should always know this, right?"

A group of special pandas: "Know, know!"

Jiang Xin opened his and learned logs, and pulled out the records of the day he was tampered with, and the logs showed that in addition to Jiang Xin himself, there was indeed another fingerprint that accessed it that day.

Then divide a screen to the background, and all the real-name authentication fingerprint databases of all and learning users can intelligently search for fingerprints that match the fingerprints accessed by the abnormal.

In just a dozen seconds, the match was successful.

Everyone blinked, thinking that they might not have come to their senses yet, and raised their hands in unison to pat their faces and rub their eyes.

The result shown in black font above cannot be changed - Huang Cancan.

Everyone reflexively looked at Huang Cancan, whose face was like ashes at this time.

What is Huang Cancan's mood? It's all over.

She didn't expect it anyway, and Xuegou had something to do with Jiang Xin's father!

The day before yesterday, when she changed Jiang Xin's practice grades, she thought about how the head teacher would react when she saw that grade, and she didn't know how happy she was.

Unexpectedly, the report handed over to the head teacher returned to Jiang Xin.

thought that she would have nothing to lose, so she could only wait for the next opportunity.

But now, everyone's eyes have changed when they look at her! Huang Cancan subconsciously turned his head to look at Han Yi, and Han Yi's face was indifferent.

Oh, that's ridiculous. After all, she still made her seventeen-year-old life a joke.

Jiang Xin is seventeen years old and lives as a school flower.

She is seventeen years old and lives as a joke.
