So, two days ago, I came to this slum for the earthlings.

And two hours ago, I started that very painful speech.

The elevator here actually needs to be started manually by the number of floors, and the microphone for the speech is still hand-held......

As I walked towards the dilapidated school gate, I complained to myself in dissatisfaction.

"Mr. Kang......" shouted a male voice with a serious Eastern European accent behind him, "please wait a minute......

My smartphone was the first to distinguish the voice for me, and it was displayed on the screen: Lecturer Aldo Kenda of the Department of Celestial Mechanics.

I stopped and turned to look: the blond-haired, brown-eyed man's features were as clean as the air of the city in the afterglow of the setting sun.

It was as if he had been born to belong to this place.

"Mr. Kenda," I smiled politely at him, "is there something wrong?" ”

"It's all right......" he walked towards me with a stack of folders under his arm, three steps and two steps, "Your presentation was wonderful and I was inspired." ”

"Uh...... Thank you. That's why I fled the lecture in a hurry – I was always overwhelmed and had a headache with flattering compliments and accostings.

"Are you free for the evening?" He looked at me expectantly.

"Evening...... "I don't have any plans, I just want to walk around the city casually.

Aldo then cautiously and tentatively invited, "That's right—I have some doubts about the details of your assumptions......

"Call me Kang Rong," I got goosebumps from the goosebumps he gave me at his endless honorific titles.

"Kang...... Kang Rong," he smiled embarrassedly, "I won't tell you, I've been preparing a paper on the quantization of celestial orbits recently, so I want to ......"

"It just so happens that I also heard about your topic from Professor An." I kind of understood his intentions, "I'm interested. Well, I'll be in the city for a few days, or ......."

"Just tonight." His Eastern European accent was even heavier, "You are a busy man, if I change your original itinerary because of some superficial problems, I will not be happy." ”

"Okay." I don't insist anymore.

A month ago, Lecturer Aldo Kenda and I met once.

It was a less formal seminar, and most of the attendees were admirers of Anke.

I recorded everyone's speeches and listened to them again after the meeting.

I can't remember the faces of those people for a long time, but I remember their names and the theories they put forward.

Aldo's theory, which seemed interesting to me, was far from what I was focused on.

Two people with the same research direction may be able to argue about a topic for a long time, but it is difficult for people to come up with new ideas.

And the conversation between two people who are in the wrong direction, although not too deep, can often inadvertently inspire.

That's why I don't rule out personal contact with Aldo.

Star Travel University is located on the outskirts of Jihe City, because there is almost no place for earthlings in the middle of the city.

It's not that the alien visitors deliberately exclude the earthlings, but because their way of life is incompatible with the earthlings - those who live in the center of the city and don't go crazy after three days are real warriors.

Despite its location in the suburbs, Star Travel University is the only place in the city where people can barely survive.

Aldo acted as a guide, taking me through the dark-toned alleys.
