The series of questions on the phone made Mulin a little confused for a moment.

However, Professor Mulin knew the name "Yang Xian".

Yang Xian, Mr. Yang, is over 60 years old this year. As an honorary professor of the Emperor, having him in the Emperor’s name is a supreme honor for the Emperor.

More than 30 years ago, Mr. Yang was the leader in the mathematics community in China. He made great contributions to China in the field of mathematics applied engineering technology!

Although Mr. Yang is old now, he still does his best for the country and the people in his post. He is an elder that Professor Mulin respects very much.

At this time, even Professor Mulin felt a little nervous when he received a call from Mr. Yang.

When he heard Mr. Yang’s question, Professor Mulin was a little confused, but when he heard the word “blue”, he seemed to understand something.

Professor Mulin explained without hesitation, "'Blue' is my teacher."

Without Lan Yin, he would not be able to solve the problem, so it is also appropriate to say that the other party is a ‘teacher’.

The person who can be called a "teacher" by Mulin, a professor in the mathematics department of the university, dare not underestimate him!

And how could a person who can solve world-class mathematical problems be an unknown little person?

For a moment, Mr. Yang was quite curious about that "Teacher Lan".

"Professor Mulin, can I meet your teacher?" Mr. Yang was sincere.

But this request was not something Mulin could make up, "I need to ask the teacher for instructions on this."

After saying the first sentence "teacher", Mulin called the teacher again and suddenly felt that he was used to it.

Although Mr. Yang Xian was eager to see the mathematician named "Blue", he also understood that this matter was not urgent.

He was highly educated and knew politeness and respect. At this time, he immediately agreed when he heard Professor Mulin's words.

"Then please help me ask if your teacher has free time, so I can fly over to see him at any time."

As one of the top mathematicians in China, Yang Xian has the qualification to use special aircraft at any time because he has made many contributions to China.

Therefore, he could say what he said to fly over to meet the other teacher at any time.

Professor Mulin responded, "I will go and tell the teacher."

When meeting with different opinions, Teacher Lan Yin has to decide.

"Okay, then I'll wait for your phone number. If you have any news, please contact me."

After the two finished speaking, they finished the call. Professor Mulin had time to figure out what Teacher Lan Yin had done so that the top Chinese mathematicians like Mr. Yang Xian and Yang could know.

Mulin himself is in the circle of mathematics, and his friends around him have too many people in the circle of mathematics, so he just took a few glances in his social platform's circle of friends and knew what was going on!

Not long ago, he just converted his problem-solving steps into an electronic version and uploaded them to the Internet, Teacher Lan Yin had actually solved three problems with four world-class math problems!

The only question she missed was solved by herself for a whole morning.

Seeing this scene, Professor Mulin was shocked!

He knew very well that the question he solved was the simplest of the four questions.

Even so, it took him a whole morning to solve it.

But Teacher Lan Yin’s time to solve the three questions add up, so she didn’t even have half a class in high school!

In other words, it took her less than twenty minutes to solve the world-class math problems!

And there are three questions in a row!
