Therefore, she was willing to give these teachers some patience.

" Alright, since you don't approve of me, you can set the questions. As long as I can't answer them, I'll lose. " Yao Tang said.

She only thought that this method was more conducive to solving the problem, but she did not expect that the male teacher's expression would become even uglier after she said that.

"You're not old, but your tone is not small. Listen well."

Next, the male teacher raised three math questions in one breath. After he finished speaking, the entire venue fell silent. Soon after, the voices of the other teachers could be heard.

"Aren't you making things difficult for me? This is a publicly acknowledged difficult problem in the world."

" That's right. You should change the question. We can't answer this question. "Some people felt that the male teacher was too harsh on Yao Tang and couldn't help but comment.

Yao Tang quietly waited for them to finish. Then she turned to the male teacher. " You only know that those questions are the most difficult math questions in the world. Have you asked around who came up with them? "

The male teacher's expression froze slightly. He really had not asked about this matter. Everyone only knew that these questions were difficult to solve. Who cared about who found them?

Yao Tang logged into the website and clicked on the section that displayed the world's most difficult math problems. She showed the male teacher the name of the person who had set the problem."The person who set the questions is me. If you don't believe me, you can call the agency now to confirm."

" Of course, this organization is overseas. If your foreign language isn't good enough, I can help you ask around. " Yao Tang said considerately.

The male teacher straightened his neck. " Who needs your help? I'll do it. Do you really think that I won't dare to investigate just because you lied? How old are you? How dare you say that you came up with this question? Just you wait. I'll go and answer it now."

Since the questions had been set, the mobile phones had been returned and the internet could be connected. The male teacher easily dialed the phone number of the organization. His English was not very standard, but he could still communicate with the other party.

After some communication, the male teacher confirmed the identity of the question setter. He hung up the phone and looked at Yao Tang with disdain." They said that the person who set the questions is a mysterious person. They only left his account number and no one has seen him before. I didn't expect you to know so much and even know how to fake his identity. "

Yao Tang didn't wait for him to continue. She logged into her foreign account and showed it to the male teacher."Excuse me, is this the account?"When the male teacher saw it, he was dumbfounded. He rubbed his eyes and confirmed again and again that this nickname was the one he had asked the staff about previously.

Seeing that the male teacher did not say anything, the other teachers also came over curiously.

"What account? Let me see it too."

Yao Tang didn't hide anything and showed her phone to the teachers.

The teachers exclaimed when they saw her ID.

"Oh my god, so you're Ms. Sandy. I've been studying your biology paper for several nights. I've been looking forward to meeting Ms. Sandy, but I heard that she's very mysterious. Ordinary people can't see her. Are you really Ms. Sandy?"

The person who said this was a professor who had a lot of achievements in biology. The question he was in charge of this time was about biology. He was almost fifty years old, but he was holding his hands nervously in front of Yao Tang, like a teacher facing a student.

Yao Tang nodded. " Yes, I am. But because I am still young, I don't want to attract too much attention. That's why I have never revealed my identity to the public. I just hope to live an ordinary student life. "

" It's actually Ms. Sandy. I've seen your thesis too. It's so profound in history. Can you answer a few of my questions, Ms. Sandy? "

Everyone surrounded Yao Tang and she answered all their questions.

Before this, there were still people who didn't believe that Yao Tang was Sandy, but as she spoke in a professional manner, the onlookers couldn't help but be mesmerized.

Usually, they would give lectures to the students. When they had time, they would flip through the books. There were very few people who could give them lessons now, but when they heard Yao Tang's points of view, they felt excited. It was like a person in the desert who had found a spring.

After an hour of questioning, Yao Tang looked at the time and said,"Everyone has a lot of questions. How about this? You can add my contact information. If you have any questions to discuss with me, we can contact each other directly."
