The most powerful attraction spell only needs a firework

In the last few days of June, Akiyama Rin once again ushered in weird events.

She got up early to go to school as usual, but the reactions of the people and the environment around her seemed a little strange—as if it was the same as yesterday.

As for why she felt this way, we have to start with the tram.

In the morning, she usually takes the 10:[-] tram, which takes [-] minutes to get to Qilibang Station, which is where her school is located.But yesterday the tram was delayed due to a breakdown, and she didn't get on until [-]:[-].

Although this time is still early for class, but a little later, the result is that there are too many people in the car.Akiyama Rin had to firmly grasp the baffle of the seat next to the door in order to barely maintain his figure.

On the seats closest to her were several children and a young girl.They were talking, and Akiyama Rin happened to be standing next to them, and could vaguely hear some of the conversation.

Among them, there is a child wearing glasses that impressed Rin Akiyama very much.He looks to be about 6 years old, and he should be a student in the lower grades of elementary school, but he can hear that he has an extremely rich reserve of knowledge in the chat.At that time, he was teaching his companions about the working principle of the tram and analyzing the cause of the failure. Rin Akiyama, a high school student, also listened with gusto.

But today, the tram was still out of order, and she still got on at [-]:[-].There are still many people in the car, and the kid is still popularizing his knowledge about trams.

Akiyama Rin didn't know whether it was a coincidence or a reappearance of time, she stared at the child, her eyes widened slightly.

"Sister, what's the matter?"

Hearing the immature child's voice, Akiyama Rin suddenly came back to his senses, realizing that his behavior just now was very impolite.She moved her eyes to the face of the boy with glasses, and said apologetically, "I'm sorry, I was rude."

Sensing that several children were casting suspicious glances at her, Akiyama Rin averted his eyes in embarrassment.It happened that the tram had arrived at Qilibang Station, and Akiyama Rin hurriedly escaped from this environment that made her feel a little bit dead.

Walking on the way to the school, Akiyama Rin gradually calmed down, thinking about what happened just now.

"Yo, Akiyama, good morning."

Kunimi Yuma came over diagonally from behind and greeted her, beside him was Sakuta Azusagawa.

"It's rare to see you on the road today, why are you late?"

"The tram is delayed."

Exactly the same dialogue.Akiyama Rin became more and more confused.

Obviously she was late yesterday, but the country view was the same as the first time I saw it. Akiyama Rin had to wonder if he had a dream last night.After all, sometimes what happens in a dream mirrors reality, giving us the feeling that we have done or said something.

But what Kuni said next made her understand that things were not that simple.

"Sakuta, did you see it? The Japanese team won!"

"...See, it was a great game."

Akiyama Rin paused.Just yesterday, Sakuta and Kunimi were very excited to discuss the news of the Japanese team's victory in the football match.

She can be sure that she has never seen news about ball games, and she doesn't even know that there are ball games recently.So if it hadn't happened once, Akiyama Rin didn't think he could predict the conversation about the game in advance.

Realizing that the girl was left behind, Azusagawa Sakuta turned around: "What's wrong?"

Akiyama Rin recalled Sakuta's completely different reaction from yesterday's excited appearance, his eyes lit up slightly: "Sakuta, yesterday...has it been compared?"

"what?"

"match."

At this moment, Azusagawa Sakuta felt that he had not been completely abandoned by the world.He looked at Akiyama Rin with scorching eyes, as if they were his family members who had been separated for more than ten years.

Seeing his reaction, Akiyama Rin also knew that he guessed right.She walked forward quickly, but because the current time is not good to discuss this matter in too much detail, she decided to talk about it later: "Come to the Science Club after school at noon, and I will ask Shang Liyang to join me."

Kunimi Yuma blinked in confusion, looking at Akiyama Rin's back with some doubts: "What are you talking about?"

"I'm talking about whether you will like me if the time repeats."

Azusagawa Sakita said weakly.However, before Kunimi could respond, he saw a wine-red haired girl rushing over, holding Guojian's arm tightly, and glaring at him contemptuously.

"Disgusting! Perverted! Didn't I tell you to leave the country!" Kamisato Shahi did not hide his anger, and criticized Sakuta Azusagawa with disgust on his face.

Sakuta Azusagawa was used to this.He glanced at the girl coldly, and said in a cold tone, "Student Shangli is on her menstrual period? Such a bad temper."

Annoyed, Kamisato Shahi blushed, she felt that she was not such a shameless person, so she stopped entangled with Sakuta Azusagawa, and strode away with her boyfriend.

Seeing Kunimi turning his head and gesturing to him repeatedly, Azusagawa Sakuta shook his head helplessly and walked into the school gate.

It was a wonderful experience for Akiyama Rin to repeat the day.She used to listen carefully in class, but once she had the thought of "I have experienced this day", Akiyama Rin couldn't help but start paying attention to the teachers and classmates in the class.

The physics teacher wore the same brown coat and yellow tie as yesterday, and taught the same content as yesterday, and even told the same bad joke.Fujii, who was sitting in the front, still knocked over the pencil case in class, and Akiyama Rin also helped her pick up the yellow watercolor pen that rolled to her seat.

If you don't consider the consequences, it's really interesting to do it all over again, Akiyama Rin thought.She who has the memory of yesterday is like a prophet, knowing the development of today's events like the back of her hand.

This is probably the saying 'Everyone is drunk and I am sober'.

"Akiyama-san, please answer this question."

Akiyama Rin finally recovered.This was a bit unexpected, she was not picked up by the teacher at all yesterday.

But because of the divergence of his thoughts just now, Akiyama Rin had no idea what the teacher asked.She stood up and looked at the teacher's face with a little confusion in her eyes.

"What is acceleration?"

Seeing that his outstanding student was distracted in class, Noriyuki Shiraishi felt a little heartbroken.He repeated the question he had just asked, and stared at Akiyama Rin.

"A physical quantity that describes how quickly a velocity changes."

"So is it a scalar or a vector?"

"It is a vector, the direction is the same as the instantaneous velocity."

Noriyuki Shiraishi nodded: "Sit down, and pay attention to the next lecture."

Hearing what the teacher said, Akiyama Rin sat down calmly.Except for this small episode, everything in the following class was normal, and there were no unexpected changes.When the bell rang for the end of get out of class at noon, Akiyama Rin went to the Science Club with a lunch box.

When she came, there was no one inside. Akiyama Rin opened the door with a key, and then moved a stool to wait while eating.Not long after, Sakuta and Rio also came.

"Good afternoon, how is your morning?" Akiyama Rin greeted with a smile.

"Not at all! Today is definitely a repeat of yesterday, it just sucks."

Hearing Sakuta Azusagawa's collapse, Futaba Rio looked calm.She skillfully took out the alcohol lamp and the iron net from the cabinet, and began to heat up the squid: "I don't have any memory at all, maybe you two had the same dream."

The transparent squid gradually turned white under the flame, and the flat sides were rolled up.Akiyama Rin was eating, and his tone was a little puzzled: "No, if this is a dream, then I am not a super god? Next time I will buy sports lottery, or watch horse racing?"

"Indeed, I don't think it's a dream. The feeling of being stepped on by Mai-san is too clear, and it can't be imitated in dreams."

Hearing Sakuta's words, Akiyama Rin had goosebumps: "Although it sounds nothing, I don't know why it feels a bit wretched to match your expression."

The squid was over cooked.Rio Futaba extinguished the alcohol lamp with the lid, and said calmly, "If it's not a dream, then there is another possibility."

"In the universe, the present state is the result of what we have done before and the cause of what will happen in the future. If there is a person who can predict the location of all forces and matter, then he can see through all past and the future.”[1]

Laplace demon.Futaba Rio's description made Akiyama Rin understand what she was talking about.This is a vision of Laplace, but in practice, it is very difficult to realize.

"Isn't this questioned in quantum mechanics? It is impossible for an electron to know its position and momentum at the same time. The clearer it is in one aspect, the greater the degree of uncertainty in another aspect." [2 ]

Azusagawa Sakuta looked confused, listening to Akiyama Rin and Futaba Rio discussing things he didn't know.He suddenly understood why there were only the two of them in the Science Society—who would want to study this kind of thing after school!

"Rin, the puberty syndrome patient is right next to you, do you think you can still think with common sense?" Rio Futaba ate bread leisurely, and glanced at the 'patient' Sakuta unemotionally.

The girl standing at the table had long gray curly hair, was wearing a white coat, and had a calm face.Looking into her brown-gray eyes, Rin Akiyama felt convinced.

"Okay, so now is Puberty Syndrome reappearing? Because of its existence, it caused our time to repeat?"

"I think so."

"Then what's the reason for the repetition? It can know the past and the future, but it doesn't want to move forward to the future?"

Rio Futaba put away the packing bag, with a calm expression: "Probably this future doesn't meet its wishes. So it keeps restarting to choose the most desired ending."

Hearing this, Sakuta Azusagawa finally couldn't bear it anymore.He put his head in his hands, with a terrified expression: "No way! Doesn't my tomorrow come when I don't know?"

"Do you have anything important tomorrow?" Akiyama Rin looked at Sakuta who was suddenly excited, feeling a little curious.

Azusagawa Sakuta looked serious, with a sad tone: "Yesterday, Mai-san agreed to my confession! I thought today would be the first day of a sweet relationship, but it turned out to be back when she didn't accept the confession!"

"That's really...too miserable." Akiyama Rin sincerely felt sorry for Sakuta.
