Cute little witch.

Chapter 1: The Little Witch is a Triple Null

"It's Lu Yu. Come up and solve this problem."

It was September. The summer sun mercilessly scorched everything on the earth. Even though the classrooms of Chenghua Middle School had air conditioning turned on, many people still felt a bit hot.

In such an environment, a "teenager" with a rather delicate appearance was wearing a black and white sweater and wrapping herself up tightly. She didn't say a word but slowly walked to the podium and stared blankly at the multimedia.

Looking at Lu Yu in this state, the math teacher thought that the other party didn't know how to do it but was embarrassed to ask. So he touched his bald head that reflected the light of the sun and said to Lu Yu, "Lu Yu, if you don't know how to do it..."

But before he could finish his words, Lu Yu directly wrote down the answer to the problem.

There was not a single step of the solution process at all. She directly jumped to the answer.

The questions for senior one are naturally not too difficult. The question here is just a quadratic equation with one unknown. But Lu Yu directly skipped the steps of setting up unknowns and calculations and directly solved the answer, which still surprised the teacher a little.

Lu Yu didn't say a word throughout the whole process. She just solved the answer directly like this. Then she stood still, slightly raised her head, and looked at the teacher who was only 1.6 meters tall.

Saying that she had to raise her head was because Lu Yu was only 1.42 meters tall. This height would still be considered normal five or six years ago. But in the present when the material level has long developed, even many primary school students are already over 1.6 meters tall.

And Lu Yu's height of 1.42 meters is also among the top in the entire classroom.Well, ranked from low to high.

Moreover, Lu Yu's shoulder width is a bit narrower than that of ordinary people. At first glance, she looks like a petite tomboy. Coupled with her eternally unchanged somewhat dull face, it can also be said to be cute and silly.

The math teacher frowned and looked at the answer on the multimedia without speaking. Several students in the audience spontaneously discussed the result.

A girl sitting in the middle of the classroom nudged the tall girl next to her with her elbow and quietly asked her, "Xinyue, have you finished this question? What's the result?"

The girl called Xinyue frowned, looked at the result on her dark green recycled paper, and glared at the answer on the multimedia with some reluctance.

"The answer is correct!" This sentence was almost squeezed out from between her teeth.

There was no way. This girl still hadn't calculated the final answer until now. But after seeing Lu Yu's answer and substituting it into her equation, she could know that this answer was completely correct.
