Chapter 509 Killing Zombies?I feel ok! 2
Xi Ying glanced at the blackboard.

This is the third subquestion of a geometry proof problem.

This kind of question usually appears in the last few big questions.

As for the third small question of the last few big questions, students will basically not answer it.

Because it is too difficult and time-consuming.

The math teacher was clearly embarrassing Xi Ying, because he just wanted to explain how to solve this problem.

He wanted Xi Ying to know that the current class was very important, and she was going to sprint for the college entrance examination, so she couldn't be so muddled anymore!

However, Xi Ying stood up from her seat, walked to the blackboard, picked up a piece of chalk and started writing.

This is not the first time Yuan Bai has been on the blackboard, and everyone has seen her handwriting.

But today's Yuan Bai's handwriting is quite different from before.

In the past, I always felt that there was a petty air, but now, flamboyant, unrestrained and unrestrained, with a murderous aura.

It took Xi Ying 5 minutes to write on the blackboard eloquently.

One reason is that there are many necessary steps for geometry proof questions, and the other reason is that her font is too crazy, so it occupies the entire blackboard.

The math teacher was stunned.

It wasn't because Xi Ying was able to solve this problem that she was stunned, nor was she stunned because of the sudden change in her handwriting, but because! !
This kind of problem-solving method is only done by graduate students!

It uses a lot of formulas that even college advanced mathematics can't learn.

This……

The math teacher looked at Xi Ying in disbelief.

Yuan Bai, who has always been passable in mathematics, is it possible that so much knowledge is suddenly loaded into his mind?

And can it be used flexibly?

"Can I go out for a while? Teacher." Xi Ying fulfilled her duty as a student and asked politely.

"You...what are you doing out there?" The math teacher's attitude changed suddenly.

Although he didn't understand what made Yuan Bai suddenly become like this, it was his honor to have such a talented student!

"Walk around."

Xi Ying's answer made the math teacher's mouth twitch.

Yuan Bai was probably the only one who told the teacher that he wanted to go out for a walk during class.

The students thought so too.

But something even stranger happened.

"Go ahead."

The math teacher agreed!
"Thank you teacher." Xi Ying walked out of the classroom.

The math teacher looked at Xi Ying's back and wiped the sweat from his forehead.

Can you not agree?

Yuan Bai's thinking in solving this question was much clearer and more flexible than his own. Lectures in front of Yuan Bai gave him a sense of déjà vu in front of Guan Gong.

It would be better to let Yuan Bai out.

The reason why Xi Ying came up with it was to see the school's structure so that she could escape when the end of the world broke out.

She still doesn't know what the mission of the main god is, so she can't leave the school for the time being.

Suppose the mission was for her to protect someone in the school.

It's class time now, and there are basically no people outside the teaching building.

Xi Ying walked around the entire school.

When I walked to the laboratory building, I found a young man in the small garden behind the building.

The boy squatted on the ground with his back to her, not knowing what he was doing.

Xi Ying walked over.

She keeps a tentative attitude towards every man who appears in her sight.

Xi Ying was wearing leather shoes, and the noise they made when they touched the ground was not too small.

But the boy didn't respond at all.

Xi Ying took a closer look.

It turned out that the boy was dissecting a frog.
