In order to figure out the perfume ratio, calculate various ingredients, and some other necessary experiments, in his previous life, Xiang Wan had taught himself a lot of knowledge, and advanced mathematics was among them.

Dou Zhibing thought that the Olympiad was very difficult, but in Xiang Wan's opinion, it was really nothing.

Therefore, when Dou Zhibing ticked one after another on the test paper handed to him by Xiang Wan, his heart trembled together.

Staring at the bright score, Dou Zhibing asked Xiang Wan in a trance: "Xiang Wan, did you cheat?"

Xiang Wan smiled and said, "Teacher Dou, I am doing the problem right under your nose." ”

"Ahh Dou Zhibing pulled the corners of his mouth a little embarrassedly, but his brows were still furrowed, and he glanced at Xiang Wan suspiciously, still uncertain: "Did you know which question the teacher was going to ask before?"

Otherwise, this kind of discipline that requires long-term training and extremely high speed and accuracy requirements for questions, how could Xiang Wan answer it so quickly, and the accuracy rate is still 100%!

"......" Xiang Wan, "Teacher Dou, otherwise, you can ask other teachers to help you come up with another set of questions, and I'll do it again?"

"Yes!" Dou Zhibing immediately decided.

Xiang Wan laughed again, but she could understand Dou Zhibing's confusion. If it were her, her reaction might be stronger than Dou Zhibing.

Dou Zhibing quickly asked the other teachers to come up with a set of test questions, took them and handed them to Xiang Wan and looked at the watch on his wrist: "Okay, let's start!"

He has to look carefully this time to see if he is cheating.

The competition time is two hours, but the current time is limited, so Dou Zhibing only asked the teacher to give the question for one hour.

He pinched a little, not good at staring all the time, but from time to time he would glance at Xiang Wan. I thought that the other party would be slower this time, but if you write later, you won't stop at all!

Half an hour later, Xiang Wan checked the test paper and handed it to Dou Zhibing.

"Teacher Dou, I'm done. Xiang Wan said with a smile.

"......" Dou Zhibing, "Oh." ”

If you said that you were in a trance before, then this time...... Dou Zhibing was even more in a trance.

Dou Zhibing took the test paper and tried to score, but more than ten seconds passed, and the pen in his hand did not move.

"Teacher Dou, you ......"

"Wait!" Dou Zhibing suddenly stood up on the spot, looked at Xiangwan deeply, and then ran towards another office with the test paper.

He was going to let the teacher who did the question grade it, and he couldn't believe himself now.

Xiang Wan didn't know why, but he still sat there obediently and waited. This section is in English, I didn't ask for leave, Dou Zhibing didn't say it, and I guess I forgot it.

Ten minutes later, Dou Zhibing walked in from outside with the test paper.

Xiang Wan didn't notice it, but just looked down at a book of Olympiad questions placed on Dou Zhibing's desk, and his preoccupied appearance revealed an indescribable calmness.

Dou Zhibing stopped at the door, staring thoughtfully at Xiang Wan, who was reading a book. He had never failed to find out that there was an Olympiad genius hidden in his class!

Is this kid going to be a pig and eating a tiger before?

Yes, it must be. He didn't believe that in less than a month, a student who always passed the exam on weekdays would develop his intelligence overnight.

This kind of myth and legend is still left to Zhao Wenhuo.

"Ahem. Dou Zhibing coughed lightly twice and approached Xiangwan.

Xiang Wan looked up, saw Dou Zhibing coming back and just wanted to stand up, but unexpectedly, Dou Zhibing stepped forward quickly, pressed his shoulder, and his tone was wrapped in indescribable complexity, and said: "Sit, sit, Xiang Wan, you really ...... What a shocking teacher!"
