The office was quiet, only the rustle of flipping books. Zhang Jing bought a boxed lunch and placed it on the table for the two. Then I left the office and didn't know what to do.

Luo Yixue began to get up from time to time and walk up to the math teacher to ask some questions, she had a lot of questions, but she was very smart, almost a little thorough, and she learned quickly.

The math teacher's surname is Wang, and even Zhang Jing called him Mr. Wang, obviously Mr. Wang, a math teacher, has some prestige in the hearts of other teachers.

At this moment, Wang Lao was drinking tea and looked at Xiang Yu with some inquiry.

Xiang Yu was doing the questions on the materials, and he wrote them quickly, as if he had already known the answer in his heart. This made Wang Lao a little suspicious, is this kid really so powerful? The title on that material is still a little difficult, this kid can actually write?

At this time, Luo Yixue had another question to ask Wang Lao. Wang Lao smiled, despite such an old age, he didn't feel troublesome at all, and he was still a little happy when he met a studious student.

Looking at the question that Luo Yixue didn't understand, he muttered: "This is a very classic body type, and most students can't do it, but it is very likely that they will get this kind of question in the college entrance examination." He raised his head and saw Xiang Yu, who was struggling to write, and said, "That little classmate should also come and listen." ”

Xiang Yu raised his head and looked at Wang Lao: "Me? ”

"Hmm." Wang Lao smiled, how did he feel that this kid was a little dull in learning.

Xiang Yu sighed, walked to Wang Lao's desk, and when he saw the topic that Wang Lao was about to explain, he hesitated for a moment and said, "Teacher, I know this question, can I go back to do the question?" ”

There are still two questions on that document that have not been solved, and the difficulty of those two questions is not comparable to the current problem. Sometimes people are like this, and when they encounter a problem that they can't know, they desperately want to find out the answer themselves.

Wang Lao was stunned for a moment, and a trace of doubt flashed in his eyes: "You mean...... Will you be able to answer this question? ”

Luo Yixue also opened her beautiful eyes wide, and looked at Xiang Yu, her eyes full of disbelief. She still knows a few catties and taels of Xiang Yu, after all, she was also a classmate at the beginning. I can't even think of a question that I can't think of for a long time, how can this guy who has achieved the tail of the crane in the first middle school be?

"That'...... Tell me what you should do. "The old man who teaches math has a good temper does not mean that he likes to be a pompous student. So he wants to test Xiang Yu.

Luo Yixue somehow worried about Xiang Yu, calling you to be reckless, asking you to brag, waiting for the teacher to get angry, see how you end.

Xiang Yu still looked casual, picked up a pen and drew in circles on the topic, interspersed with explanations: "The quadratic function here should be squared, this fifteenth power is not required to be calculated, and it will be offset with other numbers later, and then follow this formula." ”

He wrote a formula that everyone would think of but hard to think of at the bottom of the question, and drew a big circle on the paper: "Finally, according to the requirements of the question, find all the possible values of this function, and the answer is greater than zero." Because if it is less than zero, the problem is not valid, so it is easy to find out. ”

After speaking, he deliberately enlarged the answer and wrote it under the question, put down the pen after writing, but found that there had been no movement for a long time, raised his head, and saw Wang Lao and Luo Yixue staring at him without speaking.

Xiang Yu frowned, could it be that there was something wrong with what he said? So he coughed his throat and said, "Of course, this is a bit complicated, and there is another way, which is still according to this formula." ”

"Substitute this formula, find all the possible values, then use another formula, and finally list the answers according to the method of the function, and it would be good to be greater than zero. This method is simpler, but the calculation must not be wrong, otherwise the previous calculations will be wasted. ”

After he finished speaking, he found that the air was even quieter, and when he looked up, he found that Wang Lao and Luo Yi Snow Demon were even more strict.

Just as he was about to say something, Wang Lao reacted, stared at Xiang Yu and said quietly, "You...... How did you come up with these two approaches? "He was a little shocked, a student who had just transferred was so powerful, you must know that even he didn't know two methods, and he only had one solution in his mind.

Luo Yixue was also full of disbelief, as if she knew Xiang Yu on the first day, staring at him.

How can it be??

How did this guy become so powerful as if he had changed someone? Or...... This guy's previous mediocrity was all faked? His change, or after jumping off the building, could it be that his own refusal hit him, so he no longer hid his clumsiness? But...... It doesn't make sense.

He had been thinking about this question for a long time and had no clue, but he didn't seem to pay attention to it at all.

Xiang Yu saw the expressions of the two and finally understood the reason. It turned out that it was because the topic was too difficult, and they were shocked to solve it all at once. But......

"Is this really difficult?"

Xiang Yu was a little speechless about the IQ of the two. Could it be that everyone in this world is like this? In his previous life, he was a genius, and he learned everything very quickly, but genius is not a rare thing, why are these two so shocked?

In fact, Xiang Yu didn't know that he was reborn in this body, and many things were fused with this body. Including wisdom.

If you are a threesome, you must have my teacher. No matter how mediocre a person is, he will have advantages that you don't have, so a lot of Xiang Yu's character has been compensated for by the previous owner of this body. Memory, comprehension and other abilities have also been strengthened, but unfortunately even he himself is not very clear.

Listening to Xiang Yu ask in that casual tone, "Is this question difficult", Luo Yixue felt that this guy must have deliberately blocked his chest for a while to solve a difficult problem, and he still wanted to use this disdainful tone to belittle others? Who knows if you're a blind cat and a dead mouse.

She didn't know that Xiang Yu really felt that this question was very simple. It's so simple that you can see it at a glance.

Wang Lao suddenly laughed, laughing very happily, which made Xiang Yu a little inexplicable.

"Good! Good! Good! "Found a treasure! This student named Xiang Yu is definitely a good seedling, and if he is cultivated, he will definitely become a real talent! Wang Lao looked at Xiang Yu's eyes shining: "What's your name?" ”

"Xiang Yu."

"One name with the Overlord of Chu, haha, **, Xiang Yu, you are very promising!"

"Then I'll go eat first!" In a good mood, Wang Lao even lost his usual stability, he stood up, it turned out that this old man didn't even eat in order to make up for these two little guys.

"Luo Yixue, if you have any questions, you can ask Xiang Yu, I don't need me here. I'm going to dinner! After speaking, Wang Lao had already gotten up and left the office, leaving Luo Yixue with an unwilling face.

looked at Xiang Yu, this guy was still lazy and lazy, and did not show a smug expression, but she guessed that Xiang Yu must have blossomed in his heart.

Maybe this guy is a blind cat and a dead mouse! Right! It must be so!

Luo Yixue was a little angry for some reason, and made up her mind not to ask Xiang Yu any questions. Xiang Yu is also happy and idle, and continues to do the topics he didn't finish.

Half an hour later, Luo Yixue slapped the table with some annoyance.

The problem in front of her had been bothering her for a long time, and she just couldn't solve it. Wang Lao is not here, she can only think for herself. I couldn't think about it, and I gently patted the table with my little hand again. She wouldn't count on Xiang Yu, because she firmly believed that the latter had been a blind cat and a dead mouse before, and she didn't bother to demolish him.

"Quiet." Xiang Yu said without raising his head.

Luo Yixue's pink face immediately appeared with a look of shame and anger, and she glared at Xiang Yu coldly, but the latter still lowered her head and didn't even look at herself. A sense of frustration welled up in her heart, and this was the first time she felt frustrated with a man.

It's finally done!

Xiang Yu breathed a sigh of relief, all the topics on the information had been solved by him, and after looking at the boxed lunch on the table, he remembered that he seemed to have not eaten lunch yet, and he was a little hungry. Thinking of this, he decisively picked up the boxed lunch and ate it with peace of mind.

While he was eating, Luo Yixue's eyes became even more resentful. Smelling the vague smell of rice, she quietly swallowed her saliva. It's not that she doesn't have a ladylike demeanor, but she hasn't eaten for most of the day, and she's very hungry. Although there was also a lunch on the table, the title was not made, and her self-esteem and pride did not allow her to eat in peace.

Xiang Yu ate quickly, and finished eating in a short time. At this time, he was in the mood to take a look at Luo Yixue, but he saw Luo Yixue lying on the chair dejectedly, with a gel pen in her cherry mouth, and she looked listless. It's so stubborn that it hurts.

Xiang Yu smiled bitterly at the corner of his mouth.

This body's obsession with this woman is too deep, so that Xiang Yu can't even control his feelings sometimes. Standing up, he walked to Luo Yixue's side and said lightly: "Be calm when doing the topic, you used to be a quiet and peaceful person, why are you so impatient today." And this is difficult to solve? ”

Luo Yixue was slightly stunned, Xiang Yu had already picked up the pen and drew a few key conditions on the topic, and wrote a few formulas. The corners of the mouth are always casual.

"Now think about it, I won't tell you directly, I can only remind you. It's up to you to solve the problem. With that, he returned to his position and lay down to rest leisurely.

Luo Yixue suppressed the grievance and anger in her heart, the grievance was because a man who was obedient to her words at the beginning did not take herself seriously at all, and the anger was because this guy was quite high in front of him, as if he was very bad.

Taking a deep breath, Luo Yixue looked at the topic, and after seeing the conditions drawn by Xiang Yu and the formula written, the topic that she had been unable to figure out was like seeing the sun through the clouds, and suddenly became clear!

"It's so simple...... she picked up the pen, brushed and quickly wrote the answer, and then looked at Xiang Yu, her eyes were already complicated.

"How did he do it......"

(Sweating, sure enough, I couldn't help but get out of the update when I saw the two book friends bubbling in the book review area, cough cough, then today's update is very early, right, thank you god-like man, don't hit the support of my two book friends if you ask something, meow ~ that's it ~! ）
