Pure 1 cannon fodder boyfriend dressed as school grass [Transmigration Book]

The mathematician "Möbius" discovered the "Möbius ring". Unlike ordinary rings that have two sides, the Möbius ring has only one side.

If a worm lands on the ring, it can crawl all over the surface without going over its edge.

It's like a perfect and smooth melody...

Klein is also a mathematician. The "Klein bottle" he discovered has no distinction between inside and outside. No matter where it penetrates the curved surface, it still reaches the outside of the bottle.

An existence that cannot be seen with one's own eyes but is full of infinite imagination...

The "Klein bottle" is exactly the "Mobius ring" in the four-dimensional space.

When Xu Ran read the meaning of Mobius on Baidu, he saw the related concept, so he resolutely named himself Klein.

The music of Mobius is too lonely, Klein should accompany him.

I studied the songs of this post-rock singer again.

The registration time was September 17. Since then, he has released a new song on the 9th of the last month of each quarter, until March 15 this year, and released a total of 3 songs.

In the past two years, his arrangement and melody have become more and more calm and refined, and his creative ability has improved significantly.

Moreover, there is a continuation of the mood of the ten songs, from the low of complete disappointment to the thoroughness of a little out of the shadows...

Following the melody, it seems to make people feel the mental journey of restarting after a period of silence.But... not completely relieved yet.

This unfinished feeling made Xu Ran very concerned, and he really wanted to hear what kind of emotional expression the next song of "Mobius" would convey.

It is true that there are not many listeners for post-rock, and the comment section of the song is deserted.

"I don't understand, why is no one singing?"

"It seems a little sad."

"It's rock and roll? Not at all."

Xu Ran logged into the account of "Klein" and commented on ten songs in one go.

Klein's hot afternoon makes me feel cool.

Klein is in a trance and lofty, and all the pictures are condensed in the sound wall constructed by the guitar wheel at the end.

Klein is like a man's twilight, with the wind blowing.

Klein is like a summer rainstorm, pouring down, dripping freely.

……

Later, I really can't think of words to describe it.

Klein Mobius, cheers, it sounds so good, I love it.

Klein is very much looking forward to the next song!call~

After expressing, I feel much more relaxed. I just fell asleep in the music, and the phone alarm rang...

Opening his eyes with difficulty, Xu Ran immediately realized that something was wrong.

He didn't sleep for almost a whole night, and Xu Ran was extremely sleepy at the moment.

However, today is not the weekend!There are also electives in the morning.

It's really a leak in the house that happened to rain in the night.

Holding the textbook, I walked into the classroom in a daze, and found three sad facts that this elective course had to take four classes in the morning.

Classes are held in small classrooms, not lecture halls where you can fish in troubled waters.

Gu Chi was sitting in the second row next to the main entrance.

What did the original body choose?

Xu Ran had read the class schedule, but the course names were very long and contained English words, which he could not understand and remember at all.

There are no special textbooks, but advanced mathematics and probability theory are required.

However, Xu Ran can understand that for the original body, it is impossible to miss the elective courses that Gu Chi can snatch.

When he came in, Gu Chi was raising his head, his eyes happened to fall on this side, Xu Ran twitched the corner of his mouth at him, and moved to the last row.

I can't even understand the name of the course, and of course I can't understand the class.

Xu Ran lay down on the table listlessly, feeling that the teacher's voice was like a lullaby, the more he listened to it, the sleepier he became.

After the third quarter, I really couldn't stand it.He was falling asleep drowsily, when he was caught off guard by a serious call, "The boy who fell asleep in the last row is called...Xu Ran, get up and answer this question."

"What software do we use for mathematical modeling?"

Xu Ran stood up in confusion.

The students around me didn't know each other, and no one reminded me of the answer. I stood there for a while like an idiot, and then sat back in my seat with a warm face amidst the beautiful picture of the teacher's criticism and the whole class snickering.

Xu Ran was completely numb. He didn't even want to eat until after four classes in the morning. He just wanted to go back to the dormitory and sleep.

He walked out of the classroom with the textbook and mobile phone in his hand, and was about to step over the threshold when he heard someone calling himself, "Xu Ran."

Gu Chi stood behind the table, resting his fingers on the edge of the table, his quiet gaze rested on his face for a moment, and then he said softly, "You want to repeat the grade so impatiently?"

Xu Ran...

Can't wait?

Could you use the word a little better?

He was already on the verge of going berserk due to lack of sleep and bad mood. Hearing this, Xu Ran looked over with his slightly swollen eyes, and asked coldly, "You can't wait to want me to repeat the grade, right?"

Gu Chi continued to ask indifferently, "What's the name of the elective course?"

Xu Ran couldn't remember, and replied dryly, "It's just mathematics."

The other party said clearly, "Using ATB software for mathematical modeling method research."

Right, how can I remember this.

Gu Chi showed a playful smile, "The teacher just asked you what software we use for mathematical modeling and you couldn't answer it?"

Research on the method of mathematical modeling using atb software.

Indeed, the students could have laughed louder just now.

I was immersed in disappointment with myself, and heard Gu Chi say lightly, "The teacher said that I will remember your absence from class."

Xu Ran had already given up the treatment, and said in a flat voice, "Just remember it."

"Elective courses still have room for change." Gu Chi's tone eased a little, his eyes were on the front row, "Sit down."

"Why?" Xu Ran asked in displeasure, but still walked into the first row, put his mobile phone and textbooks on Gu Chi's desk, sat down with his back to the podium, and looked up at the standing boy.

"You didn't study well in one subject?"

The boy half closed his eyelids and looked down, his voice was light.

Xu Ran can understand Gu Chi staring at him like this.

Repeating a grade is not a trivial matter, not only the monitor and class guide.

He felt that he had caused the whole grade to be on high alert...

For example, a few days ago, I received a stern reminder message from the grade counselor.

Xu Ran was sleepy and desperate, and listlessly lay down on the table, "Go and tell me."

Asking for help means begging for help.

He lowered his tone, and the ending sound rose slightly.

After speaking, he didn't look at Gu Chi, but stared sideways at the blazing noon sun outside the window.

The branches swayed, and the sound of the wind mixed with the croaking cicadas in the distance came in dimly, like a movement of summer burnout.

"I know, you must be very familiar with these teachers."

After all, it is a wonderful thing that can even get full marks in the mechanical theory test.

Too different from usual, his voice is low and soft, even a little soft.

After last night's performance, Gu Chi fully confirmed one thing

Whether it is a strong sense of music or rich stage experience, Xu Ran can play the piano.

And, especially.

Today I was going to tell him about trying to be a bass player.

Actually, Gu Chi wanted to mention it last night, but was interrupted by Yan Bai.

She moved her lips, but before she could make a sound, the person lying on the table said softly again, "Please, I won't play the piano or band in the future, study hard, okay? I really don't want to repeat a grade..."

His voice became lower and lower, and finally, in a series of meaningless mutterings, he gradually fell silent.

Gu Chi bent down and saw that the man was resting on his right arm, his eyelids were closed, and he seemed to be asleep.

Fell asleep……

Sitting back on the stool speechlessly.

After lowering his eyes, every detail of the sleeping boy fell into his eyes more clearly.

He has an inch-cut head and a tough outline, and the bridge of his nose is as straight as a knife ridge. Because he fell asleep, his mouth is quietly and slightly opened...

He is slightly thin, with his left arm folded, his head resting on his outstretched right arm, and the neckline of his short sleeves collapsed, revealing a deep collarbone. On the left artery, a band-aid was creatively placed to cover it up. Live the original "gc" tattoo.

It was as if a completely different person, from appearance to temperament, was completely different from before.

Those nervous stalking, confession and stalking seemed to have nothing to do with him.

Moreover, Gu Chi really didn't expect Xu Ran to say "I won't play the piano or band in the future, I must study hard and don't want to repeat the grade."

After all, this is the first time I have seen this strange thing that I can't even remember the name of the course.

Recalling the rule that repeat students are not allowed to participate in inter-school activities...

Gu Chi dismissed his thoughts, got up and was about to leave the classroom, his gaze swept across the tabletop.

Xu Ran's textbooks and mobile phone were still thrown on the table.

The footsteps stopped again.

Is he overconfident in the security of the school, or is he too careless?

He moved his eyes back to the sleeping face, and frowned...

The sound of cicadas outside the window fluctuated from far to near. The boy listened to it for a while, then sat back in his seat.

In the uncomfortable sleeping position prone to cervical spondylosis, Xu Ran woke up quickly.

The neck was sore, and it took several seconds to turn back a little bit, and suddenly saw the deep gaze on the opposite side of the table, shivering, and completely awake.

Gu Chi crossed his hands behind his head, and leaned lazily on the edge of the back table.

Xu Ran recalled it for a while, and said cautiously, "Why are you still here?"

A little speechlessness soon appeared in the eyes of the other party, even... admiration, Xu Ran didn't answer, just staggered his eyes, got up and walked out, glanced at the textbooks and mobile phones on the table, and said lightly, "Put your mobile phone away when you sleep. On the table, do you want to give it away?"

Xu Ran? ?

When the boy walked to the door of the classroom, Xu Ran finally realized the meaning of his words. Facing the tall and straight figure, he gritted his teeth and said, "I can afford it even if I lose it."

The author has something to say. Chi Chi can help you look at your phone at most, like you?Don't even think about it.

Burn off, brother wants to learn.
