He is a Ph.D. student in the Mathematics Department of Yanda University. He is also Wang Xuecai's apprentice, Tao Zhixing.

"Dean, teacher, something has happened!"

Fu Zhendong:???

Qin Luo

Wang Xuecai...

Something big? Is there something bigger than video teaching?

"Xiao Tao, come and have a drink and speak slowly." Wang Xuecai first came back to God, took a cup of water and handed it to Tao Zhixing..

"Gulu" "Gulu ~"

after a cup of water, Tao Zhixing's face was a little more calm.

He said solemnly, "Sir, Princeton replied."

There is only one Princeton in the world, that is Princeton University, and there is only one reason for Princeton to reply, that is, the mathematical Yearbook!

"Come on, show me." Wang Xuecai didn't care about his old arms and legs, so he came to Tao Zhixing and grabbed the package in his hand.

At this moment, Wang Xuecai was not an old man in his 70s, but a young man in his twenties.

He opened the package in two and three times. A hardcover book appeared in front of the public. On the book, the four characters of the mathematical Yearbook were printed.

In addition, there was a letter in the package.

Qin Luo's name is written on his head with a quill pen.

Wang Xuecai stopped and looked up at Qin Luo: "are you coming or am I coming?"

While speaking, Wang Xuecai did not show any sign of handing in the letter.

"Thank you, Wang Yuan." Qin Luo mouth corners twitch to say.

He gave Qin Luo a look at you, and Wang Xuecai opened the envelope with a click.

It was a handwritten letter:

"Mr: Qin"

"Dear Professor Qin, when you see this letter, I think you have already opened the package, and you have also seen the mathematics journal which was made overnight. As you can see, your paper has passed the most stringent examination in Princeton and will be the most outstanding 24 papers of the year The paper has been included in the mathematical Yearbook. Congratulations, young man. You are the youngest collector of the Yearbook of mathematics since its establishment... "

Then came the almost painless praise.

"Finally, I'm very glad to receive your paper. It's a great honor for us in Princeton to have your trust in the Yearbook of mathematics."

"Looking forward to our meeting again, on the podium in Princeton..."

At the end of the letter was written the name: Princeton: Denis.

The letter is not over yet.

There is also a string of small words behind the signature of dlinese: attached, this is written by Professor dline's assistant: there is an invitation letter and a plane ticket in the envelope, asking Professor Qin to attend on time - Fiona.

Put down the letter, Wang Xuecai very solemnly took out the invitation letter from the envelope.

The invitation is simple, just a piece of paper.

On the invitation, the door of Princeton University was printed.

Dear Professor Qin Luo:

we sincerely invite Professor Qin Luo to attend the annual report meeting at Princeton University on January 8.

At the back of the invitation, there is a ticket for American Airlines.

Princeton invited Qin Luo to attend the annual report meeting!

Looking at the invitation letter in his hand, Wang Xuecai shivered and flushed.

Princeton University, one of the best universities in the United States, is not known as the holy land of academic research.

and the year-end report meeting of Princeton University is a golden age for the whole academic community.
