In the gaze of countless students, the ark shook its head and simply declared the end of the lecture.

Then, without stopping for a moment, he turned away from the staircase classroom.

Yet the ark just walked out of the classroom, and a voice chased it from behind.

“Please wait, Professor Lu! ”

Hearing the familiar mandarin, the ark stopped and looked back, only a young lady with a face value of 78 points was seen, chased out of the classroom.

Looking at the girl he was chasing, he said, "Are you? ”

After a few breaths, the girl stretched out her index finger to reveal a slightly messy Liu Hai smile.

“My name is Hu Ying... I went to sophomore year at Humboldt University! ”

The ark nodded: "Hello, Mr. Hu Ying, can I help you? ”

“Something happened," he turned his eyes, Hu Ying did not directly talk about business, but said with a smile, "Well... Professor Lu is too obstinate to read, can I call you Lu Shen? ”

Stubborn?

The Ark has read it several times in its heart, how do you feel comfortable reading it?

But he doesn't care much about what people call himself.

The name is just a symbol. The three animals of 201 have been called elbows, hooves, halo elbows for so many years. Listen, don't you get used to it?

So the ark nodded and the clouds whispered, “Okay, I don't mind. ”

Whispering smile, playfully said: “For what I have called you, Lu Shen, can you tell me how to be as good as you? ”

Turns out it's a learning problem.

The ark laughed, and Yan Yue said, “What do you do professionally? ”

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

Double degree?

Ark eyebrows picked.

He doesn't know much about international trade, but applied mathematics is his old skill.

“Do you have paper and a pen? ”

Is this about leaving a phone number for yourself?

“Yes,” Hu Ying's eyes suddenly lit up when he heard the phrase. He immediately turned the small book and ballpoint pen out of the bag and handed it to him. At the same time, he laughed and said, "In the future, please ask Lu Shendo to teach you more! ”

“I can't talk, but I can teach you a little bit about applied mathematics. ”

She took the pen and paper from her hand, and the ark didn't give a shit, and she wrote it on the transcript.

Time goes by.

He looked at the canoe and turned a page, and his eyes were a little suspicious.

Just as she wondered what kind of social platform the account number couldn't finish writing a page, the ark stopped the pen in her hand and gave it back to her with Ben.

“This is a book list that I flipped through in the library at the University of Humboldt when I was free and useful for applied mathematics. ”

Hu Ying:????

Seeing her standing there for half a day without talking, the ark nodded satisfactorily, thinking she was caught in thought.

“The rest of you think for yourself, there is no skill but diligence. ”

“That's all I can do for you. ”

Come on, he didn't say anything anymore. He left Wu Ying speechless and turned away.

By the time he reached the school entrance, Ark had entered the supermarket and bought some letters 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 he had promised the principal.

I bought something and walked out of the supermarket with a plastic bag, and when the ark was ready to take the car back to the hotel, I suddenly saw the girl who had just stopped him come after me.

“Wait, wait...”

Stopped and watched as her knees gasped and her boat stunned slightly.

“Anything else? ”

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

“… what is it? ”

“Letter!”

A letter was pulled out of the bag, and Hu Ying stuffed it in the hands of the ark with some exasperation.

After receiving the letter, the Ark looked at her with confusion.

I always feel…

Her eyes seem a little resentful?

But after half a day of thinking, he couldn't think of a connection to himself, so he set it aside.

Turning the envelope to the front, the ark simply swept its eyes.

When he saw the address of the sender, he couldn't help but stunned.

Embassy in Germany?

The letter was opened and the ark looked down along the first line.

[… Dear Professor Ark, I am Ambassador Hu Minde to Germany. On behalf of the Embassy in Germany and all German diplomats, I would like to congratulate you on your outstanding achievements…]

Beyond the body of the diplomatic rhetoric, the ark looked directly at the last line.

[… My wife and I are very interested in your stories and admire your successive achievements in mathematics, theoretical physics, and chemistry, and wonder if it would be an honor to have dinner with you?

[- Ambassador Hu Minde to Germany]

The letter was closed and the Ark looked at Hu Ying with suspicion.

This letter doesn't seem to have anything wrong, and probably no one will joke about this random questioning.

He just can't figure it out.

Why did one of her students have this handwritten letter from the ambassador?

The question was not hidden in my heart, and the ark asked directly.

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

In addition to serving as an office assistant at the Embassy, she is also President of the Chinese Students Association at the University of Humboldt and Director General of the Ryude Students Association in Berlin…

Of course, these are minor.

Most importantly, she has a father who is a diplomat...

……

In any case, the ambassador was invited, and this face had to be given.

Leaving the invitation, the Ark allowed Miss Hu, who still had some resentment in her eyes, to tell the ambassador for herself that she was willing to go to the appointment and set the time for this dinner for tonight.

Tomorrow he has other arrangements, probably not in Berlin for a while, and it would be better to settle these matters as soon as possible.

Back at the hotel, the Ark temporarily set aside the invitation, took out the letter and envelope that had just been bought from the supermarket, and sat at the table and began to think about the letter that Principal Xu had asked for.

When he promised to do this, he didn't find it hard to write, but when he really started writing, he started to make some mistakes.

Imagine, when I first studied undergraduate studies, my politics had been wandering down and down the pass line, and I had not even seen such written letters to the relevant departments.

Trying to pen a few lines, he found himself writing at the end, turning into an essay.

He shook his head and leaned back on the chair with some headaches on the ark.

“I knew it was such a hassle, why don't you just sign the blank paper and mail it to Principal Xu? ”

That's a good idea, but he definitely can't do that.

After all, as an accomplished scholar, he must be held accountable for every word he says.

After several attempts, the Ark finally decided to abandon this lame imitation, rubbing the paper into a basket and retrieving a brand new piece of white paper.

As a scholar, or solid point, there is nothing better to say.

Reconsideration, he raised the pen on paper and rewrote the line title.

"Discussion on the Application Prospects of Computational Science in the Frontier Research Field and Future Trends in Chemistry and Materials Disciplines"
