"Please open page 72 of the textbook, and today we will talk about the definition of the angle bisector......

This is an ordinary middle school classroom, with bare green bricks under the low wall, and a white~pink wall covered with dust and footprints, so that the whole classroom still retains the atmosphere of the 80s of the last century.

The classroom was full of thirty people, and among the slightly green faces, there was a boy sitting against the wall, staring straight at the blackboard.

"In Ice-Storm's spell model, the optimal distribution of prisms has been solved, and then ...... This body obviously doesn't have enough computing power, and it seems that I will have to go to my father's lab to borrow their supercomputer again on the weekend. However, in order to use a computer, the conic angle dataset that needs to be calculated must be modeled in an iterative way before it can be calculated, and the magic utilization rate is a factor, and the spell model must also be modified accordingly to make room for future optimization......"

Thoughts were racing in Lin Yi's mind, and while he was doing mental arithmetic, he casually marked out symbols on his notebook that no one could understand.

"Hey~~Hey~~"

Feeling that the tip of a pen was poking his body, Lin Yi, whose brain was running at high speed, turned his head a little sluggishly, and looked at the pretty face in front of him: "...... Senior, what's the matter?"

"What's the matter, you're a big-headed ghost~" The squad leader stood up the book to cover his face, and whispered to Lin Yi: "Don't be in a daze, concentrate on listening to the class~!"

Lin Yi really wants to say, you actually stand up the book like this, it's actually more conspicuous......

"Zhang Silu and Lin Yi over there, don't whisper in class!" But it's too late......

Hiss, there was a pain in the instep, and Lin Yi received the "Girl's Angry Stomping"!

Lin Yi glanced at her sadly. Blame me?

Hmph! The head of the class turned his head arrogantly, leaving only the back of Lin Yi's head with a ponytail.

......

With a sigh, Lin Yi picked up the book, but his mind no longer knew where it had drifted.

Yes, Lin Yi knows that he is very special, and since he was three years old, he has realized this.

Although he has spent more than ten years in this world, Lin Yi still feels incredible about what happened to him.

Lin Yi has two identities, or rather, two bodies.

Every three nights or so, when Lin Yi fell asleep, the next morning, he would wake up in another world, in another capacity.

Similarly, when a day is spent in that identity, he will wake up on the earth as Lin Yi and start a new day.

If you describe a person's life as a movie, every day is a frame.

Lin Yi's life is like breaking up every frame of the two films and inserting each other.

This peculiar situation, Lin Yi didn't tell anyone, it was the same in both worlds.

It's not that they don't trust their relatives, it's just that even if they say it very seriously, no one will take it seriously, right? After all, this situation is too much like the fantasy of the second-year teenagers.

If you were in this peculiar situation, what would you do?

Lin Yi's choice is to be an ordinary person.

Because, in another world, to be precise, should be her, too unusual.

......

"Jingle Bell~~"

When the bell rang for the end of class, Lin Yi walked to the windowsill at the back of the classroom and leaned against the window to look at the scenery outside.

This year is also the last year of this historic school building, and starting next year, students from Nancheng Middle School will move to the new school building that is being built opposite.

Lin Yi stroked the mottled and broken cement on the windowsill, watched the ants crawl on the dead leaves floating to the window, and for a moment, he suddenly felt that he could appreciate the loneliness of this ancient school building.

"Hey~ Lin Yi, do you think our class leader is interesting to you?" a tall and chubby guy approached Lin Yi and said in a sneaky tone that was extremely inconsistent with his figure.

Lin Yi looked back at this guy who always preached some house things to him, and a smile appeared on his face: "If I were you, I would never say this at such a time." ”

"What do you mean?" the fat man was a little puzzled, "but I saw the class leader walk out of the classroom...... Hey, hey, hey~ I was wrong, I was wrong, the class leader spared his life!"

The pathetic fat man was grabbed by the ear and thrown aside, leaving only the red-faced girl and Lin Yi speechless.

Looking at the girl with a slightly red face, an impulse suddenly surged into Lin Yi's heart.

"Class leader, you said that a person's life is completely for another person, is that okay?"

"What?" The girl looked at Lin Yi, who was usually always silent, with some surprise, wondering why he suddenly asked such a question, could it be......

Just before the girl thought about it more and more crookedly, and was about to make up her brain in a strange direction, Lin Yi corrected her words in time: "No, no, it is more precise, it should be a person, half of his life is for the other half of his life, is that good?"

The girl put her finger on her chin, thought about it for a moment, and then replied, "What a strange question you ask, isn't life like this? Studying, playing each takes up half of the time, no, studying and working should be more......"

It seems that this can't be said, but Lin Yi immediately thought of a better analogy.

"Or to use an online game, one account has two characters, and one of the characters gives up all activities, adventures, explorations, etc., and spends all the time collecting, providing material help to the other account, okay?"

This time, the class leader looked at Lin Yi with some worried eyes: "What's good or not, it's just a game, you can play how you want?" But if you are a game, it should be right to focus on practicing a number first." ”

Is it true that you have to focus on a good number first, but ......

"By the way, what are you writing?" the squad leader took out a notebook, "I wanted to ask you for a long time, what are these strange symbols that you always write and draw in your notebook?"

"Huh...... That's the Aaronic Continent's words, "it's just my random graffiti." ”

"Yes, I feel that these symbols are quite regular......" The girl held the notebook and looked at it for a while, then gave up.

Her gaze followed Lin Yi to the newly built teaching building opposite the playground.

"Speaking of which, we will be able to move to the new classroom next year, and this old teaching building should also be demolished, Uncle Huang of the Housing and Construction Commission said, ah......" She covered her mouth and carefully observed Lin Yi's expression, until she confirmed that Lin Yi had indeed just been staring at the other side in a daze, and then breathed a sigh of relief.

"yes, it's time to tear it down. "But why......

Lin Yi's slow answer reached the ears of the girl who turned around and was about to leave, she turned back angrily, and stared at Lin Yi with an inexplicable face.

After a while, the girl finally sighed: "I'm so stupid to be honest with you stupid......"

Looking at the back of the girl leaving, Lin Yi also sighed in her heart.

The other party's delicate and sensitive mind, how could he not understand. Nancheng Middle School, named after Nancheng, recruits mainly students who live in the old city in the south, and most of the residents in this area are naturally not noble.

As the daughter of the new mayor, she carefully concealed her identity in the school, lest she hurt the self-esteem of ordinary children.

After all, just an "ordinary" fifteen-year-old girl, and in another world, she is only "five years old" herself. Thinking of this, Lin Yi couldn't help laughing, he took one last look at the class leader who was mingling with a group of girls in the center of the classroom, and then put his thoughts on the unfinished spell modeling.
