Zhang Cheng didn't erase the steps written by Wang Anqi, but directly picked up the chalk and wrote in the blank space next to him.

Wang Fen hugged his arms and sneered on the side, although the classmates below didn't understand what kind of nerves Zhang Cheng was making and jumped out to die, but they were all waiting to see a good show.

But soon everyone's expressions changed, especially Wang Fen, a big mouth slowly opened, opening wider and wider, and could no longer close, and the classmates sitting below also had a ghostly expression.

I have to say that this problem is very complicated, and the process of solving it is also very cumbersome, even if Wang Anqi knows the steps to solve the problem, he just thought while writing, stopped writing, and it took a while to solve the problem.

But looking at it now, the chalk in Zhang Cheng's hand never stopped at all, and soon wrote a long list of formulas below, and the key is in the calculation of the formula, he didn't pause at all, and directly wrote the calculation results behind.

The students below were hurriedly calculating on the scratch paper, but they couldn't keep up with Zhang Cheng's rhythm at all.

"Is this Nima still human!"

"Such a complex formula can also rely on mental arithmetic? Are you kidding me? ”

Just when everyone was crazy, Zhang Cheng also finished writing the final answer, threw the chalk in his hand, and looked at Wang Fen.

Wang Fen was still in extreme shock, as Zhang Cheng's homeroom teacher for three years, she couldn't know more about Zhang Cheng, even if she was killed, she didn't believe that Zhang Cheng could solve this problem.

But the facts were in front of her, she couldn't believe it, and Wang Fen couldn't care about it, so she took out the calculator directly from her bag and pressed it cracklingly, hoping to find out the error in Zhang Cheng's solution.

But soon the corners of her mouth twitched again, and she found that both the solution ideas and the answers were completely correct, and they were a little too correct, better than the answers that their teaching team racked their brains to come up with.

And compared with Wang Anqi's answer next to him, the solution given by Zhang Cheng is simpler and faster, and it is clear who is better and who is inferior in the exam that is racing against time.

"How? Is there something wrong? Zhang Cheng asked with a light smile.

"End...... Completely correct......" Wang Fen hesitated for a long time, but had no choice but to announce, and the students in the entire classroom were in an uproar.

"This ...... How is this possible! You cheat! Wang Anqi suddenly jumped up, pointed at Zhang Cheng and shouted.

"I said, eldest sister, can you think before you speak."

Wang Anqi was stunned, yes, this question was assigned yesterday, and Zhang Cheng only came to class today, and he didn't know that Wang Fen would come up with this question, so he wouldn't prepare in advance.

And then again, her problem-solving steps are also taught by others, and if you want to talk about cheating, she is really cheating......

But if she wants to admit that Zhang Cheng is better than her, it is really worse than death, Wang Anqi's face instantly turned pale, and she sat down staggeringly, without saying a word.

Zhang Cheng looked at Wang Anqi's depressed appearance, and shook his head slightly, just because of this psychological quality, he was embarrassed to argue with his brother.

"Now that the problem is solved, do I not have to go out and stand now?" Zhang Cheng saw that Wang Fen was still in a daze, so he had to remind.

"Huh?" Wang Fen turned his head, looked Zhang Cheng up and down, and couldn't help asking, "Are you really Zhang Cheng?" Someone can't be impersonating, right?"

Zhang Cheng rolled his eyes, "Teacher, have you watched too many movies, do you want me to show you your ID card?" ”

Wang Fen also found that he was talking nonsense, Zhang Cheng was alone, what was worth thinking about others, and no one would pretend to be him.

"You...... Go back and sit. Wang Fen had to say unwillingly.

Zhang Cheng walked towards his seat with his head held high, and the whole class looked at him, grinning widely.

"Impossible! Why is Zhang Cheng so different from before today? Is this still the scumbag? Obviously it's a top student! ”

"What a scholar! Look at this solution idea, Wang Anqi is weaker than him! The key is that this Nima is still mentally arithmetic, and he is simply learning God! ”

"You said Zhang Cheng wouldn't be ghosted, right?"

"Have you eaten too much, you heard that after being taken by a ghost, you will suddenly do the question! It's not good to give me a dozen of these ghosts! ”

"Then how did he ......?"

"You ask me, why do I ask who to go, look at my expression, I am also confused."

"Do you think it could be that he was hiding his strength before? Planning to make a sudden shocking reversal during the college entrance examination? ”

"You're insane! Figure what? Can hidden strength be hidden for three years? Aren't you afraid of hiding yourself? ”

The whole classroom exploded, and everyone turned their heads to each other, frantically venting their shock.

If they knew that Zhang Cheng had completed all the math courses in the three years of high school in just ten minutes just now, it was estimated that they would all be frightened crazy.

Shen Biao's face was very ugly, his eyes were staring at Zhang Cheng gloomily, and at the same time, he was very puzzled in his heart.

Damn it! Let this kid be in the limelight again! But how could he suddenly become smarter? Was it really pretended before?

But Shen Biao couldn't figure it out even if he wanted to break his head, pretending to be a scumbag, and he was at the bottom for three consecutive years...... What's so good about that?

Zhang Cheng ignored the shocked crowd and walked to his place and sat down.

Siyan turned his head, picked up a thumbs up, his face was full of smiles, and he lowered his voice and said, "Brother Cheng, this is more than pretending to be a hundred points!" Is it the answer I just found on the Internet with my mobile phone when I was out there? ”

Zhang Cheng smiled, didn't explain, reminisced about the feeling just now, and then slowly closed his eyes.

With so many things suddenly loaded into his brain, he was also a little worried and wanted to tidy it up.

After brushing it carefully, he soon found that what he was thinking about now could be roughly divided into two parts.

Part of it is my nineteen years of memories and all kinds of miscellaneous things, the knowledge I just learned in the textbook is also in it, the content of this part is very clear, there is no need to try to recall, as long as the heart moves, the corresponding things will automatically emerge.

And the other part is the information that inexplicably came out of his mind after his death, which is very huge, at least several times the number of his own memory, but they are all vague and incomprehensible, and once he forcibly distinguishes them, his head hurts terribly.

But fortunately, although this information is usually not clear, it will reveal one or two by itself at a critical moment, and Zhang Cheng can 'live' until now, which can be regarded as relying on the guidance of this information.

Zhang Cheng only realized his extraordinariness at this moment, and he could judge from the information that could be distinguished, there should be few people who would have their own situation after death, although it was said that he only had three years, but now it seems that he still has a lot to do in these three years.

Since the time is not long, then I must 'live' the wonderful, and make up for all the time wasted in the front!
