Before Duan Fengliu could finish speaking, Xu Yuntian held his hand hard, and with a crisp sound, the egg was broken and the egg yolks were scattered all over the ground.

"Your glory is in front of me, I'll be the eunuch first!" Xu Yuntian said viciously.

"Boy, let go! It hurts so much!" Duan Fengliu screamed.

"Are you going to apologize to Shangguan Wanqing?" Xu Yuntian said coldly.

"I apologize, I apologize!" Duan Fengliu immediately admitted defeat.

Xu Yuntian let go of his hand, Duan Fengliu knelt down at Shangguan Wanqing, and said reluctantly: "Wanqing, I'm sorry."

His speech was very vague, and Xu Yuntian said coldly: "Duan Fengliu, are your tongue broken or your throat broken? The sound is a little louder, I can't hear it!"

As he said that, Xu Yuntian stepped on Duan Fengliu's palm, Duan Fengliu screamed immediately like a pig. Xu Yuntian let go and smiled, "The scream is quite loud, it seems that his throat is fine!"

Duan Fengliu was frightened by Xu Yuntian's methods. He was just a rich young man who was wearing clothes and raising his hands to open his mouth. When did he suffer such torture? He hurriedly shouted to Shangguan Wanqing: "Wanqing, I'm sorry!"

"Damn, you called Wanqing, Grandma Shangguan!" Xu Yuntian said sternly.

Duan Fengliu hurriedly shouted: "Grandma Shangguan, I was wrong!"

Shangguan Wanqing glanced at Xu Yuntian and said, "I'm that big!"

Xu Yuntian said coldly to Duan Fengliu: "Duan Fengliu, get out of here immediately. Don't let me see you again, otherwise I will hit you once when I see you!"

Duan Fengliu hurriedly got up, turned around and ran. Without running two steps, Xu Yuntian's cold voice came from behind: "I told you to get out, haven't you heard it clearly?"

"I'm leaving?" Duan Fengliu said in confusion.

"Are you getting out of here? You didn't see the egg rolling on the ground, you got out of here like that, do you understand!" Xu Yuntian glared at Duan Fengliu and said fiercely.

Duan Fengliu's face was pale and she cursed in her heart: "Boy, you humiliated me in every way today. I, Duan Fengliu, will definitely make you repay it thousands of times!"

Under Xu Yuntian's intimidation, Duan Fengliu rolled on the ground and rolled down the steps from the corridor, falling all over her head.

Many students covered their arms and laughed. They looked at Xu Yuntian in surprise. The student was so brave that he dared to humiliate Duan Fengliu like this.

"Xu Yuntian, thank you, but you have to be careful. Duan Fengliu is not easy to mess with. The Duan family has a great influence in Lanhai City." Shangguan Wanqing frowned.

"If you humiliate Duan Fengliu like this, the Duan family will not let you go. You'd better go outside to hide for a few days." Shangguan Wanqing said with concern.

"Haha, nothing, I, Xu Yuntian, are not a person who is afraid of trouble. The Duan family should not mess with me, otherwise I will make them a family member!" Xu Yuntian smiled disdainfully.

"Xu Yuntian, who are you? You don't look like a student!" Shangguan Wanqing looked at Xu Yuntian and said in confusion.

She had never seen a bold student like Xu Yuntian dare to offend the Duan family. Could it be that Xu Yuntian is also a person with background? Shangguan Wanqing stared at Xu Yuntian.

"What are you doing when you look at me like this? You can't you fall in love with me, right?" Xu Yuntian teased at Shangguan Wanqing.

Shangguan Wanqing glared at Xu Yuntian with a slightly red face and said, "What do you think? I will like you. The person I like is Long Tianyun."

"Haha, kidding, I know the person you like is Long Tianyun."

"By the way, I happened to have a math problem asking you for advice." Xu Yuntian looked at Shangguan Wanqing and said with a smile.

"Oh, what kind of math problem is it?" Shangguan Wanqing asked with interest.

Xu Yuntian took out a piece of paper with a calculus-based advanced mathematics problem and handed it to Shangguan Wanqing.

Shangguan Wanqing took over the math problem, and she was immediately attracted by the math problem, "Oh! Your math problem is quite interesting, let me think about it!" Shangguan Wanqing stared at the math problem.

"Wanqing, you won't just think about it in this corridor, right?" Xu Yuntian looked at Shangguan Wanqing and smiled.

"Then let's go to the pavilion of the college to think about it. The place is very quiet." Shangguan Wanqing said, walking, staring at the math problems and thinking.

Xu Yuntian and Shangguan Wanqing went to the college's rest garden, which was a place for students to rest extracurricularly. Several pavilions were built, and many students sat in the pavilion to rest.

The two of them sat down in a pavilion. Shangguan Wanqing took out a pen and paper and wrote it on the paper. Then she frowned. The answer was crossed out and then answered.

Xu Yuntian sat next to Shangguan Wanqing, looking at her intently, and smiled at the corner of his mouth. This math problem was a math problem he did when he was twelve years old.

It was a question for the mathematics Olympiad held by a certain country. At that time, there were more than 500 students in the competition. Only five people answered the question correctly, and Xu Yuntian was one of them.

He took it out for Shangguan Wanqing to see what stage of Shangguan Wanqing's math level has reached and how much time it will take for her to solve it.

About half an hour later, Shangguan Wanqing's brows stretched out, his face showed joy, and he wrote with a brush.

After a while, Shangguan Wanqing put down his pen, turned his head to look at Xu Yuntian and smiled and said, "This is really difficult to do math problems. No wonder you can't do it. I finally solved it. Look, ask me if you don't understand anything."

Xu Yuntian took the answer to the math problem and glanced at it. Shangguan Wanqing's answer was wrong, which was difficult to expose it. He deliberately said in surprise: "Oh! So this question is done like this! Why didn't I expect it!"

Shangguan Wanqing glanced at Xu Yuntian and smiled and said, "I can only answer this math problem genius class, and no one else can do it."

"Wanqing, what does this mean? I can't understand it, please explain it to me." Xu Yuntian pointed to Shangguan Wanqing's wrong steps and said.

Shangguan Wanqing took a look and said, "This is what it is here."

Suddenly she patted her forehead and said, "Oh! I seem to have made a mistake, no, I want to calculate it again."

Shangguan Wanqing picked up the pen and started calculating. This time the calculation took longer, about an hour. She frowned and put down the pen and stopped calculating.

"Has it been made?" Xu Yuntian asked intentionally.

Shangguan Wanqing turned his head and looked at Xu Yuntian and said, "This math problem is too difficult. I can't think of it for a moment. Where did you get the math problem?"

"I found it on the site. I didn't expect it to be so difficult that even you, the top student, could not answer it." Xu Yuntian sighed deliberately.

"I can't even do it, so don't talk about you. I think you should do it simply. Such a difficult question doesn't make much sense to you." Shangguan Wanqing looked at Xu Yuntiandao.

Xu Yuntian nodded and said, "Yes, this math problem is too difficult for me, so I'd better do it simple."

The math problem given by Xu Yuntian just now belongs to the five-star math problem in the mathematics community. Those who can solve five-star math problems are either mathematicians or super math geniuses.
