Quick Wear: Report to the Host, You have been Attacked!

Xi Yan glanced at the blackboard.

This is the third question for a geometric proof.

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

And the third question of the last few big questions, the students basically will not answer.

Because it is too difficult and takes too much time.

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

He wanted Xi Xi to know that the current class is very important. She is the one who wants to sprint for the college entrance examination. She can't go on like this anymore!

However Xi Xi stood up from his position, walked to the blackboard, picked up a piece of chalk, and wrote in a quizzical manner.

It's not the first time that Yuan Bai has been on the blackboard. Everyone has read her handwriting.

But today's Yuan Bai has a very different handwriting.

I used to think there was a small family spirit, but now, Long Fei Feng Wu, free and easy, also carried a murderous Ling Ling.

It took Xi Min five minutes to write a blackboard in a haughty manner.

One is because there are many necessary steps for the geometric proof question, and the other is that her font is too crazy, so it takes up the entire blackboard.

The math teacher was stunned.

It wasn't because Xi Xi was able to solve the problem, nor was she stunned because of her sudden change of handwriting, but because! !!

This kind of problem-solving method is only done by graduate students!

It uses a lot of formulas that even college high numbers can't learn.

This……

The math teacher looked at Xi Xun inconceivably.

This Yuan Bai, who has always been able to pass mathematics, could suddenly have so much knowledge in his head?

And flexible?

"Can I go out for a while? Teacher." Xi Yan performed his duty as a student and asked politely.

"You ... what are you going out for?" The attitude of the math teacher suddenly changed.

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

"Walk around."

Xi's answer made the math teacher's mouth twitched.

During the class, he told the teacher that he was going out, and it was probably Yuan Bai that was a wonderful work.

The students think so too.

But something stranger happened.

"Go ahead."

The math teacher agreed!

"Thank you, teacher." Xi Yan stepped out of the classroom.

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

Can't agree.

Yuan Bai's solution to this problem is much clearer and more flexible than that of him. Lectures in front of Yuan Bai give him a sense of vision in front of Guan Gong.

It might as well let Yuan Bai out.

The reason Xi Xi came up was to see the structure of this school so that he could escape when the end of the world erupted.

She has no idea what the mission of the Lord God is, so she cannot leave school for the time being.

If the task is to let her protect someone in the school.

It is class time, and there are basically no people outside the teaching building.

Xi Yi walked around the school.

When walking to the experimental building, a boy was found in the small garden behind it.

The boy crouched on the ground with her back to her, wondering what she was doing.

Xi Yan walked over.

She was tentative about every man who appeared in her sight.

Xi Yan wore leather shoes, and the sound of contact with the ground was not small.

But the boy did not respond at all.

Xi Yan took a closer look.

It turned out that the teenager was dissecting a frog.
