In order to figure out the ratio of aromatherapy, calculate various ingredients, and some other necessary experiments, Xiang Wan taught himself a lot of knowledge in his previous life, and advanced mathematics is included.

Dou Zhibing thought it was difficult to make the Olympiad, but in Xiangwan's opinion, it really was nothing.

Therefore, when Dou Zhibing checked one by one on the test papers given to him by Xiang Wan, his heart trembled.

Staring at the bright score, Dou Zhibing asked Xiang Wan in a daze: "Xiangwan, have you cheated?"

Xiang Wan laughed and said, "Teacher Dou, I did the questions under your nose."

"Ah, oh, oh." Dou Zhibing pulled the corner of his mouth a little embarrassedly, but his brows were still frowning, and he glanced at Xiangwan suspiciously, and said uncertainly: "Did you know what question the teacher was going to ask before?"

Otherwise, how could Xiangwan answer such a subject that requires long-term training and extremely high requirements for answering questions and accuracy, so the accuracy rate is still 100%!

"..." Xiang Wan, "Teacher Dou, why don't you do this? You ask other teachers to help you get the questions set again, and I'll do it again?"

"Yes!" Dou Zhibing made a quick decision.

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 other teachers to give a set of test questions, took them over and handed them to Xiangwan and looked at the watch on his wrist: "Okay, let's start!"

He has to look carefully this time, whether Xiang Wan cheated or not.

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

He pinched the point and kept staring at it, but from time to time he would look at Xiangwan. He thought the other party would be slower this time, but unexpectedly, Xiangwan wrote as if he was a god, and he would not stop at all!

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

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

"..." Dou Zhibing, "Oh."

If I were to be trance before, then this time... Dou Zhibing became even more trance.

Dou Zhibing held the test paper and tried to score, but more than ten seconds passed, but the pen in his hand remained motionless.

"Teacher Dou, you..."

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

He wanted the teacher who set the questions to score, and he couldn't believe himself now.

Xiang Wan was unknown, but he still sat there obediently waiting. This section was in English. He didn't ask for leave, and Dou Zhibing didn't say it, so he probably forgot it.

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

Xiangwan didn't notice it, but just looked down at a collection of Olympiad questions placed on Dou Zhibing's desk. His concentration showed indescribable calmness.

Dou Zhibing stopped at the door and stared at Xiang Wan who was reading a book and thoughtfully. He never realized that there was a genius of mathematics in his class.

Could this child have been pretending to be a pig and eating a tiger before?

Yes, it must be. If you want to learn the subject of Mathematical Olympiad well, it is impossible to do it overnight. He doesn't believe that in less than a month, a student who always passes the pass line in the daily exam will develop his intelligence overnight.

Let this myth and legend be left to Zhao Wenhuo to tell.

"Cough cough." Dou Zhibing coughed twice and approached Xiangwan.
