"Even this tough security guard was taught a lesson by him!"

"They'll definitely behave themselves from now on!"

"You even knocked my bike over last time, now you've met your match, haven't you? You deserve to be taught a lesson!"

The teachers and students watching all felt very relieved.

Li Yi smiled slightly and said to Principal Xu, "Principal Xu, let's go now."

Principal Xu then came to his senses and quickly said, "Alright, Professor Li, please!"

As he spoke, he personally led Li Yi and Zhang Yifei through the crowd toward the School of Mathematics.

During the time that the security guards were waiting at the school gate, Professor Hua Wenyu also arrived.

Li Yi was going to explain that difficult mathematical problem in fluid mechanics to them. Zhang Yifei had never understood it before, so Li Yi told her to walk around the campus and he would come down to find her later.

“Okay, brother, Feifei is waiting for you on campus.”

Zhang Yifei nodded and obediently wandered around downstairs.

She thought to herself, "This change in identity is too fast."

Yesterday afternoon, it was Brother Li Yi again who was wandering around the campus waiting for me.

Today, I ended up wandering around the campus waiting for him.

At the School of Mathematics, Li Yi demonstrated the derivation of the problem on the blackboard for everyone. The moment he wrote down the answer and formula, President Xu Ben'an, Professor Hua Wenyu, and the other professors in the project team all applauded.

Everyone was incredibly excited.

Professor Li has solved a mathematical problem that has troubled them for many years.

The most excited person was Hua Wenyu, the project leader. He stepped forward, shook Li Yi's hand, and thanked him repeatedly: "Professor Li, thank you so much. If it weren't for you, we don't know when we would have been able to overcome this challenge."

President Xu Ben'an, however, had a different perspective. He said, "Professor Li, you were only appointed as our professor yesterday, and today you've solved a major problem for us and for the country. The West can no longer hold us back in this field. With this mathematical problem solved, our country's high-speed rocket manufacturing technology is halfway to success. Moreover, the development of the next generation of fighter jets has also been greatly improved. Professor Li, you have made a tremendous contribution to the country!"

Li Yi was speechless. This is allowed?

I just casually solved a problem, and unexpectedly it directly solved a major problem that the West was using to strangle us.

After another round of praise and casual conversation, Li Yi was finally able to leave.

Only then did he have time to reply to Zhou Mei's message.

When Li Yi looked, he saw that Zhou Mei had sent several messages, along with a series of crying emojis!
