Chapter 535 Killing Zombies? I Think It’s Ok! 2

Xi Ying glanced at the blackboard.

This is the third question of a geometric proof problem.

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

As for the third small question in the last few big questions, students basically don't know how to answer it.

Because it’s too difficult and time-consuming.

The math teacher was clearly trying to embarrass 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. She was going to rush for the college entrance examination and she could not continue to be so ignorant!

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 very different from before.

In the past, I always felt that I had a small family spirit, but now, I am full of dragons and phoenixes, unruly and free, and also carries an overbearing murderous aura.

Xi Ying spent five minutes writing on the blackboard eloquently.

Firstly, it is because there are many necessary steps for geometric proof problems, and secondly, her font is too wild, so it takes up the entire blackboard.

The math teacher was shocked.

It was not because Xi Ying was able to solve this problem that she was shocked, nor because of the sudden change in her handwriting, but because! !

This kind of problem-solving method is something only graduate students can do!

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

this……

The math teacher looked at Xi Ying in disbelief.

Could it be that Yuan Bai, who had always failed in mathematics, suddenly had so much knowledge in his head?

And it can still be used flexibly?

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

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

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

"Wander around."

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

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

The students think so too.

But something even stranger happened.

"Go ahead."

The math teacher actually 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't you agree?

Yuan Bai's way of solving this problem was much clearer and more flexible than his. Giving lectures in front of Yuan Bai gave him a sense of déjà vu as if he was playing tricks on Guan Gong.

It would be better to let Yuan Bai out.

The reason why Xi Ying came up with it was to see the structure of this school so that he could escape when the apocalypse broke out.

She still doesn't know what the Lord God's mission is, so she can't leave the school for the time being.

What if the task was for her to protect someone in the school?

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

Xi Ying walked around the entire school.

When I walked to the experimental 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 remains tentative with every man who comes into her sight.

Xi Ying was wearing leather shoes, and the sound they made when they came into contact with the ground was not too quiet.

But the boy didn't react at all.

Xi Ying took a closer look.

It turned out that the boy was dissecting a frog.
