Next was Huang Yuxin's class. She started teaching, talking about advanced mathematics calculus, which Xu Yuntian had already mastered.

Instead of listening to the class, he observed the thirty-seven students in the class, and wanted to protect Shangguan Wanqing. Of course, he had to figure out who all the students in the genius class were and whether it was possible that they had a bad person.

After observing all the students in the genius class, Xu Yuntian confirmed that these people were all students and did not get into bad people.

Then he took out his cell phone and sent a text message to Yan Xiaoyu, asking him to investigate all the staff files of Blue Ocean Academy to see if there are any suspicious people in the employees.

After Yan Xiaoyu received Xu Yuntian's text message, he immediately turned on his laptop and typed on the keyboard with both hands. After a moment, he entered the Personnel Department Archives Center of Blue Ocean College.

There are 583 employees in Blue Ocean College, of which 480 are teachers, and the remaining are logistics employees, including canteens, finance, security guards, cleaners, etc.

Yan Xiaoyu retrieved all employee personnel files and inspected them one by one, especially the recently transferred employee files to Blue Ocean College, which must be carefully reviewed.

Xu Yuntian, from the genius class, was fine, so she played games with her mobile phone. Huang Yuxin on the podium was writing math problems on the blackboard. After she finished writing math problems, she found that Xu Yuntian lowered her head and played with her mobile phone under the table.

She was very unhappy. She hated students whispering to each other in class, sleeping, reading other books, playing with mobile phones, etc., thinking that this was disrespect for her.

She immediately walked down the podium and walked towards Xu Yuntian. Xu Yuntian felt footsteps coming towards him. When she looked up and saw Huang Yuxin coming, she knew that she must have noticed that he was playing with his cell phone.

Xu Yuntian hid his phone calmly, then looked at Huang Yuxin as if nothing had happened. Huang Yuxin walked to Xu Yuntian, stretched out his hand and said coldly: "Support it!"

Xu Yuntian looked at Huang Yuxin and pretended to be confused and said, "What are you going to do?"

"Don't be smart! You are playing with your phone below, don't think I didn't see it, hand over the phone!" Huang Yuxin said coldly.

After she said this, all the students in the class turned their heads and looked at Xu Yuntian. Someone whispered: "Isn't this the student who came here just today? He is so brave that he actually plays with his mobile phone in class!"

"He is dead this time! He dares to play with his mobile phone in Teacher Huang's class!" A student whispered.

"Teacher Huang, are you dazzled? I didn't play with my phone? I didn't even bring my phone with me. How can I play with my phone?" Xu Yuntian smiled calmly.

"It seems that you are not honest, you didn't bring your phone, right? What if I find out you brought your phone with you?" Huang Yuxin said coldly.

"Teacher Huang, if you find your phone, I admit that I played with it and let you punish me. If you don't find your phone, you will be dazzled." Xu Yuntian said with a smile.

"Stand up! Let me search!" Huang Yuxin pointed at Xu Yuntiandao.

Xu Yuntian immediately stood up, spread his hands, and said with a smile: "Teacher Huang, you can search whatever you want!"

Huang Yuxin immediately searched Xu Yuntian's top pocket, but couldn't find her phone. Then she looked at Xu Yuntian's trouser pocket. She was a little reluctant to search, after all, Xu Yuntian was a boy.

"You suspect that I put my hand in my pocket, right? I'll turn it over to show you." Xu Yuntian immediately took out his pocket and had nothing.

"Look clearly. I don't have a cell phone on me. You're dazzled." Xu Yuntian looked at Huang Yuxin and said with a smile.

Huang Yuxin was very puzzled. She clearly saw Xu Yuntian playing with his mobile phone on the podium, but searched it and found that she didn't find the phone. Where was the phone hidden?

Her eyes fell below Xu Yuntian, and it was bulging below. The phone would not hide that place, right? Thinking of this, Huang Yuxin's face turned slightly red, and of course it was difficult to search that place.

Xu Yuntian saw Huang Yuxin's meaning, "Teacher Huang, you suspect that I hid my phone in my crotch, right? Why don't I take off my pants and show you?" Xu Yuntian said with a smile.

After he said this, many students covered their smiles, especially the female students' faces turned red, Shangguan Wanqing's face also turned red, and she cursed quietly: "Bored!"

Huang Yuxin's face turned red, she couldn't do this, she glared at Xu Yuntian and said, "Are you bored?"

Then she returned to the podium and continued, looking at everyone and said, "What I wrote on the blackboard just now was the International Mathematical Olympiad Competition six years ago. It was a difficult problem. Only one person did it at that time. That person was a math genius and was only twelve years old at that time."

"Look at who can do it?"

The students looked at the math problems on the blackboard, and many people shook their heads and said, "This is too difficult. A twelve-year-old man actually did it. He must be a foreign math genius."

"Six years ago, he was twelve years old, and now he should be eighteen. There are not many mathematical geniuses in the international world at this age. They should be Douglassi, a mathematical genius from a certain country." Some people speculated.

"Yes! It should be Douglassi from a certain country. He is a recognized math genius. He won two Olympiads championships." A college nodded in agreement.

"Don't guess it. Douglas also participated that year. He won the second place, and the first place winner was from our country." Huang Yuxin said.

"Teacher Huang, the number one person in our country is actually a person. What is his name? Why haven't we heard of it?" Shangguan Wanqing asked.

"The name used by that math genius is Long Tianyun. Later, I checked all the domestic archives and found this person. It seemed to be missing." Huang Yuxin said in surprise.

Over the years, she has been searching for the twelve-year-old mathematical genius at that time, but she couldn't find any information about him. She asked many domestic mathematicians, but they all said that there was no such person.

"Oh! This Long Tianyun is so powerful that he can solve this math problem at the age of twelve!" Shangguan Wanqing sighed.

She looked at the math problems on the blackboard, but she couldn't solve them. She had always been very proud of her math talent and always thought she was the number one math genius. Unexpectedly, Long Tianyun solved them when she was twelve years old.

"Yes, he is currently the top mathematics genius. It took me a year to solve this math problem. Later, after looking at his solution, I realized that his solution was too concise and I felt ashamed of myself," Huang Yuxin sighed.

"Teacher Huang, you have worked hard for a year to solve it! Then we may not be able to solve this math problem in our lifetime!" Some students sighed.

"Teacher Huang, give me a month and I will definitely solve this math problem!" Shangguan Wanqing stood up and said confidently.

Huang Yuxin smiled and nodded, "Good Wanqing, I look forward to you solving this math problem in a month!"

"Students, we must have the confidence of Shangguan Wanqing. We will be in the National Olympiad Mathematics Competition for more than half a month. It is said that this time it is a topic that Osgao, the father of mathematics, has been studying, but he has not solved it. You must work hard!" Huang Yuxin said with a smile.

"Teacher Huang, don't worry, I will definitely win the first place this time!" Shangguan Wanqing said firmly.
Chapter completed!
