After Chu Yunchen took the test paper, he took a general look at it, and said with disgust: "Teacher Chen, they all said that it is difficult for you to give a one, but why is it still so simple?" ”

Chen Xin gasped and said as calmly as possible: "You shouldn't know how to do it, right?" ”

"How is that possible!?" Chu Yunchen immediately shook his head.

"Then you can do it first......" Chen Xin was about to get angry to the limit.

"Okay, give me the pen." Chu Yunchen nodded.

"......" Chen Xin handed the pen to the other party.

After Chu Yunchen took it, he immediately started to do it, first of all, it was a multiple-choice question, which gave people the feeling that he wrote down the answer without even reading it.

And Chen Xin was already shocked beyond measure, originally thought that the other party was just scribbling, but after reading three questions, he found that he ...... It was all right!

Soon, Chu Yunchen wrote the first page, and Chen Xin could only look at it selectively, there was no way, the other party's answering speed was too fast, and he couldn't keep up at all.

"How is that possible?"

Chen Xin can be sure and certain that the questions in this test paper have not been leaked, but the results are ...... I read the questions myself, and the answers are correct.

As for the luck of the people, two or three ways are said in the past, but five and six are ...... She didn't believe it anyway.

"Teacher Chen, in order not to waste time, I won't write the process of solving the big questions, okay?" Chu Yunchen has already done the back.

"Good ......" Chen Xin at this time, his head was already blank.

Without understanding the question process, Chu Yunchen did the following questions well in a few clicks, and the entire test paper added up, and it only took five minutes to take the test.

And Chen Xin was still in a sluggish state and didn't react.

"Teacher Chen......"

Chu Yunchen shouted, which made her hurriedly take the other party's test paper and check it.

"Right, right, or right......"

Chen Xin's scalp was numb, how did the other party do it, didn't he lie, but the real demon has reached this point, but this is really appalling.

Chu Yunchen waited boredly for a while and then said, "Teacher Chen, I can go back, class will be going soon." ”

"Okay." Chen Xin just wanted to calm down, but soon, he thought of an idea and said, "Come to the office again after school." ”

"Okay then." Chu Yunchen agreed indifferently.

Watching the other party go out, Chen Xin's expression was full of strangeness, but in order to confirm whether the other party was really so demonic, she planned to personally ask him to do a few big questions.

As soon as Chu Yunchen came to the classroom, he was despised by a group of students, you know, his current reputation is super stinky.

……

in the office.

Chen Xin checked the questions on the test paper, and there was no doubt that they were all correct.

Compared to before, her heart was much calmer, after all, it had been expected.

"I'll just make a few difficult questions......"

So, Chen Xin meditated hard and spent a lot of time to come up with five major questions, the extent of which has completely exceeded the knowledge learned in high school.

After school, Chu Yunchen first told Ye Yuran, after all, he went back with her, and then came to the office.

"Let's do these five questions." Chen Xin added, "You must write down the problem-solving process clearly." ”

As he spoke, he placed his new question and pen in front of the other party.

"It's ...... again"

Chu Yunchen sighed, then looked at the title, and said, "Why is it still so simple?" ”

"You hurry up and do ......" Chen Xin urged, she just wanted to prove that the other party was really so rebellious?

"Okay." Chu Yunchen agreed, then picked up the pen and started to do it, for him, unless there is no answer, there is no question that cannot be done.

Chen Xin just stared at it with wide eyes, and then, his body couldn't help but tremble.

Five big questions, from the process to the answer, the other party can be said to do it in one go, and it only took seven or eight minutes to complete it, she can be sure that even if those mathematics and science students who have graduated from college do it, there is no thirty minutes that will never be able to do it, unless it is the kind of special grades, but now......

"Am I dreaming......"

The other party did the question, the answers were all correct, as for the problem-solving process, because it was written too fast, Chen Xin could only take a cursory look, but it was certain, it was absolutely correct, even if she let herself do it, it would not reach this level.

"Teacher Chen, the question is done, I can go back." Chu Yunchen said, Ye Yuran was still waiting outside.

"Wait, I'll ask a few more questions, and you'll answer me verbally?" Chen Xin, who reacted, hurriedly said.

"Okay, hurry up then." Looking at the other party's expression, Chu Yunchen felt funny in his heart.

"What is 6844 times 562 divided by 488?" Chen Xin first came up with a simple multiplication and division problem, and at the same time, wrote it on a piece of paper, after all, it was just a casual thing, and she was afraid that she would forget it.

"Equal to 7881 points 8196721311." Chu Yunchen immediately replied.

"Say it again, I'll make a note of it." To be honest, Chen Xin didn't know if the other party's answer was right or not, and he needed to verify it to know.

So, Chu Yunchen said it again, and Chen Xin, after writing down the answer on paper, immediately wrote a formula and calculated it, and the result was exactly the same.

Chen Xin took a deep breath, and then asked three questions in succession, one more difficult than the other, but Chu Yunchen answered it at the first time, and the answer was completely correct.

Now, Chen Xin has determined that the other party is really a pervert and a demon, and it is unprecedented.

You know, even if others can do mental arithmetic, it will take some time, and he, as long as he knows the topic, can say it directly, just like an intelligent robot in a science fiction movie.

Wait, he can't really be a robot, otherwise, how could a human reach this level?

"Teacher Chen, what kind of eyes do you have?" Chu Yunchen said speechlessly.

"You put your hand out." Chen Xin said expressionlessly.

"Do what?" Chu Yunchen asked.

"Don't ask why, just stretch it." Chen Xin said a little domineeringly.

"Okay." Chu Yunchen stretched out his hand indifferently.

And Chen Xin, pinched the back of the other party's hand, it felt like a real person, and there were obvious tendons, it should not be a robot, and immediately, she felt extremely ridiculous about her idea.

"Teacher Chen, you can't take a fancy to me, do you?" Chu Yunchen grabbed the opponent's wrist with his backhand.

"Don't talk nonsense." Chen Xin's face turned red, and he said, "You hurry up and let go." ”

"Looks like I'm thinking too much." Chu Yunchen shook his head and let go of his hand with a look of pity, not knowing if it was real or pretended.

Chen Xin hurriedly withdrew her hand, and at the same time breathed a sigh of relief, she was really worried about the situation just now, she was really worried that the other party would do something excessive to herself, and then, with a serious expression, she said: "In the future, you can not do the test papers I sent or the homework I assigned, and you can sleep or secretly play with your mobile phone in class, but you can't disturb other students, do you know?" ”

She can't help but say such a thing, the other party's demon level can't be taught at all.

"It's just a small thing." Chu Yunchen said with a smile.

"Then it's settled." Chen Xin nodded, it was a contract between the two.
