In the stunned eyes of countless students, Lu Zhou shook his head and simply announced the end of the lecture.

Then, without stopping for a moment, he turned and left the lecture hall.

However, Lu Zhou had just walked out of the classroom not far before a voice chased after him.

"Please wait a minute, Professor Lu!"

Hearing the familiar Mandarin, Lu Zhou stopped, looked back, and saw a young lady with a good appearance of seven or eight points, chasing out of the classroom.

Looking at the girl chasing after him, he asked, "Are you?" ”

After a few breaths, the girl stretched out her index finger and brushed off her somewhat messy bangs, revealing a smile.

"My name is Hu Ying...... Sophomore at Humboldt University! ”

Lu Zhou nodded: "Hello Hu Ying, is there anything wrong?" ”

"Something," her eyes rolled, but Hu Ying didn't get down to business directly, but said with a smile on her face, "That's ...... Professor Lu is too awkward to pronounce, can I call you Lu Shen? ”

Mouthful?

Lu Zhou read it a few times in his heart, how to read it and how to feel smooth.

But he doesn't care much about what others call him.

The name is just a symbol, and the three animals in 201 have been called elbows, hooves, and elbows for so many years, don't you get used to listening to them?

So, Lu Zhou nodded, and Yun said lightly: "Okay, I have no opinion." ”

Hu Ying pursed her lips and smiled, and said playfully: "That Lu Shen, for the sake of me calling you Lu Shen, can you tell me, how can I be as good as you?" ”

It turned out to be a learning problem.

Lu Zhou smiled and said kindly, "What major are you?" ”

Hu Ying immediately said: "Applied mathematics, and international trade!" ”

Double degree?

Lu Zhou raised his eyebrows.

He didn't know much about international trade, but applied mathematics was his old profession.

"Do you have pen and paper?"

Is this to leave yourself a phone number?

"Yes, yes," Hearing this, Hu Ying's eyes suddenly lit up, and she immediately took out a small notebook and a ballpoint pen from her bag and handed them over, and said with a smile, "In the future, I will ask Lu Shen for more advice!" ”

"I can't talk about teaching, but I can teach you a little bit of applied math experience."

Taking the pen and paper from her hand, Lu Zhou didn't talk nonsense, and wrote freely on the manuscript.

The clock ticked by.

Seeing that Lu Zhou had turned the page, Hu Ying's eyes were a little suspicious.

Just when she was thinking about what kind of social platform account she couldn't write a single page, Lu Zhou stopped the pen in his hand and returned it to her with the small notebook.

"This is a list of books that I flipped through in the library of Humboldt University when I had nothing to do, and it is quite helpful for the study of applied mathematics."

Hu Ying: ???

Seeing that she was stunned there for a long time without speaking, Lu Zhou thought that she was in a state of thought, so he nodded with satisfaction.

"For the rest, you figure it out for yourself, and you don't have any skills other than the word diligence."

"That's all I can help you with."

After that, he didn't say anything more, left Hu Ying, who was silent, where he was, turned around and walked away.

When he walked to the school gate, Lu Zhou stopped by the supermarket and bought some stationery and envelopes.

In order to prevent himself from forgetting things because he was too busy, he decided to take advantage of his free time in the afternoon to write the letter that he promised Principal Xu.

After buying things, he walked out of the supermarket with a plastic bag, and just as Lu Zhou was about to take the car back to the hotel, he suddenly saw the girl who had stopped him just now chasing after him again.

"Wait, wait......"

Stopping and looking at Hu Ying, who was panting with her knees, Lu Zhou was slightly stunned.

"Anything else?"

"There's one more thing I forgot to give you."

“…… What is it? ”

"Faith!"

Pulling out a letter from her bag, Hu Ying stuffed it into Lu Zhou's hand with some anger.

Taking the letter, Lu Zhou glanced at her suspiciously.

I always feel ......

There seemed to be some resentment in her eyes?

But after thinking about it for a long time, he couldn't think of a connection with himself, so he put this matter aside.

Flipping the envelope to the front, Lu Zhou glanced at it simply.

When he saw the address of the letter, he couldn't help but be slightly stunned.

Embassy in Germany?

Unwrapping the letter, Lu Zhou looked down the first line.

【…… Dear Professor Lu Zhou, I am Ambassador Hu Mingde. On behalf of the Embassy in Germany and all the diplomatic staff in Germany, I would like to congratulate you on your outstanding achievements in receiving the Hoffmann Medal......]

Beyond the text mixed with diplomatic rhetoric, Lu Zhou looked directly at the last line.

【…… My wife and I are very interested in your deeds, and admire your successes in mathematics, theoretical physics, and chemistry, and wonder if we will have the privilege of having dinner with you. 】

[——Ambassador to Germany Hu Mingde]

Closing the letter, Lu Zhou glanced at Hu Ying suspiciously.

There doesn't seem to be anything wrong with this letter, and probably no one will joke about such a casual question.

It's just that he still can't figure it out.

Why did this handwritten letter, written by the ambassador, end up in the hands of one of her students?

didn't hide this question in his heart, Lu Zhou asked directly.

After asking, Lu Zhou learned that the identity of Miss Hu was not just a student of Humboldt University.

In addition to her work as an office assistant at the embassy, she is also the president of the Humboldt University Chinese Student Association and the director general of the Berlin Student Aid Association......

Of course, these are secondary.

The main thing is that she has a dad who is a diplomat......

……

In any case, the ambassador is invited, and this face still has to be given.

Leaving the invitation letter, Lu Zhou asked Miss Hu, who still had a little resentment in her eyes, to tell the ambassador for herself, saying that she was willing to go to the appointment, and set the time for this dinner tonight.

He has other arrangements for tomorrow, and he may not be in Berlin for a while, so it is better to settle these matters as soon as possible.

Back in the hotel, Lu Zhou put the invitation aside for the time being, took out the stationery and envelope he had just bought from the supermarket, sat down at the table and began to think about the letter that Principal Xu had requested.

When he first agreed to this matter, he didn't think there was anything difficult to write this letter, but when he actually started writing, he began to make some mistakes.

Come to think of it, when I was an undergraduate, my politics had always been above and below the passing line, and I had never even seen this kind of written letter to the relevant departments.

After trying to put pen to paper, he found that he ended up writing and writing, and it all turned into an essay.

Shaking his head, Lu Zhou leaned back in his chair with some headaches.

"I knew it was so troublesome, so I just signed it on a blank piece of paper and mailed it to Principal Xu."

It was a good idea, but he certainly couldn't do it.

After all, as a disciplined scholar, he must be held accountable for everything he says.

After a few attempts, Lu Zhou finally decided to abandon this crappy imitation, crumpled the paper into a ball and threw it into the paper basket, and took out a brand new white paper.

As a scholar, it's better to be realistic, and what to say.

Reimagining, he picked up a pen on paper and rewrote a line of headings.
