The most powerful attraction spell only needs a firework

Akiyama Rin stared at the bubbling transparent solution in front of him, and yawned sleepily.

Her face was delicate and beautiful, her eyelashes were curled and long, and they were trembling slightly due to the force of closing her eyes, like a butterfly fluttering its wings.However, the thick blue and black under her eyes slightly spoiled the overall beauty, making her look haggard.

It's summer vacation now, but at this time Akiyama Rinto is in the classroom of the Science Club.

The warm yellow sunlight shines into the classroom through the glass windows, illuminating a bright path in front of Akiyama Rin.She lay on the table and saw the specks of dust flying up and down in the light beam, forming a sacred and quiet picture.

Although she really didn't want to spoil the mood at the moment, the constant secretion of mucus in her nasal cavity made her unable to maintain her elegance. Akiyama Rin grabbed the tissue at hand and began to blow her nose expressionlessly.

Both eyes stared at Akiyama Rin together.Seeing the puzzled expressions of her friends, she said sullenly, "Go ahead, I may have a cold."

Because of the difficulty in breathing, the girl's nasal voice is very obvious.Azusagawa Sakuta leaned on the back of the chair, watched Akiyama Rin wipe his nose continuously, with a teasing expression on his face: "Akiyama, the sun these two days is not so big, anyone who can catch a cold in summer is an idiot."

"Oh," Akiyama Rin threw the tissue into the trash can, and smiled at Azusagawa Sakuta, "When Sakuta goes to work in the restaurant, let Kunimi put you in the freezer. Sakuta who has a cold like this Also stupid."

"I'm really sorry, Guojian won't work with me today."

Futaba Rio saw Rin Akiyama's red nose, and she had a worried look on her face.She put down the beaker in her hand, went to the back room and took out a tissue box and handed it to Rin Akiyama: "Rin, do you want to go to the hospital?"

"It's okay, it's okay," Akiyama Rin waved his hand indifferently, and took the paper box, "I don't know why, when I woke up this morning, I found my head hurt a little, and my eyes were swollen, obviously I was at home yesterday and nothing happened. Do it."

"You have such big dark circles, did you catch a cold while playing games last night?"

"It's possible, anyway, it's not a big deal."

Seeing Akiyama Rin's completely indifferent look, Futaba Rio sighed: "If you feel uncomfortable, just say it. If you are sick, you should see a doctor in time."

Akiyama Rin, who was gently comforted, was moved for a while. She hugged Li Yang's arm and rubbed it, and said meaningfully: "Wuwuwu, you are still good to me, unlike some people who only mock me."

There are only three people in the Science Society, who else can there be besides the two of them!Azusagawa Sakita twitched the corners of her mouth, and decided to continue outputting: "Hey, Akiyama, don't rub it, I'll rub my nose on Futaba's clothes later."

Rio's clothes are white coats, if the nose is stained... imagined this scene, and Akiyama Rin suddenly felt a little sick.She let go of Rio's arm with a stiff expression, and stared at Sakuta Azusagawa through gritted teeth: "Sakuta, do you know why you are single?"

"With such a poisonous mouth, no girl would like it."

Azusagawa Sakuta seemed particularly indifferent to Akiyama Rin's criticism.He shrugged nonchalantly, resting his chin on his hands: "It's as if you're out of order. Although Guo Jian isn't with us in the basketball club, which one of the four of us is the current one?"

"That's true," Akiyama Rin looked at the chemical reagents on the laboratory table, and shook his head with a smile. "If there is no place to go, who would come to school to make up experimental records during the summer vacation?"

"It's just that everyone else is dating and we're learning. It's so inspiring."

Rio Futaba looked at Rin Akiyama and Sakuta Azusagawa sitting at the table, and was a little silent.

Because there are only a few members, the classrooms of the Science Club are not big, but the equipment and instruments that should be used for experiments are still complete.Rin and Sakuta were sitting in two seats on the same laboratory table, with smiles on their faces, bickering and playing with each other, just like she had seen countless times before.

Looking at them, Futaba Rio felt more and more that she and them were in two separate time and space. She looked at each other from a distance at the still end, watching the performance of Akiyama Rin and Azusagawa Sakuta like watching a movie.

But she knew that she was indeed in the same space as them.

Futaba Rio took a deep breath, let go of her clenched right hand, and walked between Akiyama Rin and Azusagawa Sakuta: "There is no way, if you don't make up the experiment, the science club may be abolished next semester .”

"Wow!" Akiyama Rin shouted in surprise.

To be honest, Akiyama Rin thinks that their science society is really watery.In addition to doing experiments regularly, every club activity is basically their chat time, which is very leisurely compared with the basketball club in Kuni.

After entering the second year of high school, because no freshmen are willing to come, they have become old fritters and even do less regular experiments, but Akiyama Rin did not expect that this might be abolished.She became serious with a straight face: "So it's so serious! Rio, you have to say it earlier."

Azusagawa Sakuta also restrained the casualness on his face, looked at Rio Futaba and said seriously: "Indeed, the Science Club is our happy hometown. If the Science Club is gone, where else can we find local water time?"

Hearing the brown-haired boy's serious and humorous words, Akiyama Rin silently held his forehead: "Sakuta, although you are telling the truth, you have to polish it up occasionally to make it sound better."

Then, she glanced at the gray-haired girl with a quiet face, blinked and asked her, "Rio?"

"That can't be helped, who told me not to look at the atmosphere is my greatest advantage?"

The boastful words came out of Sakuta's mouth, and Akiyama Rin suddenly felt a little familiar.She seems to remember that someone said recently that Sakuta's advantage is not to look at the atmosphere, but whether this person is herself or who, Akiyama Rin found that she couldn't remember.

But how could she suddenly praise Azusagawa Sakuta, Akiyama Rin suspected that she probably didn't sleep well, so she had this illusion.

Looking at the orange-haired girl's tightly furrowed brows, Rio Futaba suddenly felt nervous.The slightly tense nerves allowed her to hear her own heartbeat clearly. She held her breath and asked tentatively, "Rin, what's wrong?"

"It's okay," Akiyama Rin came back to her senses, she cheered up and took Rio Futaba's hand and walked towards the laboratory bench where she was just now, "Let's start mending now! What are you doing?"

The girl's unaware expression didn't look like she was lying. Seeing this, Rio Futaba quietly breathed a sigh of relief.She hooked Akiyama Rin's hand obediently, and looked at the reagent bottle on the table: "I'm going to make cuprous chloride."

"Hey——" Akiyama Rin looked at the beaker and test tube on the table in surprise, and asked with a tilted head, "What do you use? I remember that I need to pass sulfur dioxide, why didn't I see the instrument?"

Futaba Rio smiled and shook her head, pointed to the white powder on the table: "This time I want to change the method. I think it's easier to prepare it with a solution of sodium sulfite, sodium chloride, and copper sulfate."

According to the several reagents given by Futaba Rio, Akiyama Rin silently made up the equation in his heart, and then found that it was indeed much simpler-after all, it only needed to mix the three solutions together.She raised her eyebrows and said in a brisk tone: "Isn't it easy? Let's solve the first one right away."

Akiyama Rin made several powders into aqueous solutions.The copper sulfate solution presents a clear blue color in the test tube, which looks clear and beautiful.But after adding the remaining two solutions, the chemical reaction turned the liquid in the test tube into a somewhat thick grass green, and the cuprous chloride precipitate they wanted accumulated at the bottom of the test tube.

"Akiyama, are you sure you didn't make a mistake?" Sakuta Azusagawa looked sideways at the strangely colored test tube, and murmured inexplicably, "It was beautiful just now, but now it looks like that kind of goblin green slime, which is kind of disgusting. "

Akiyama Rin shook the test tube in his hand and said seriously: "It's not wrong, that's how it is."

"That's right," Rio Futaba saw Sakuta's disgusted expression, and pushed his glasses a little funny, "After filtering it out, it's the precipitation of cuprous chloride."

Akiyama Rin put the test tube away, and tidied up the countertop a little: "Yes, but don't look at it as a bit disgusting now, the flame reaction of cuprous chloride is very beautiful."

"Pure blue, if made into fireworks, it will be very dreamy."

Sakuta Azusagawa often feels that he is out of place with the Science Society.In front of Futaba Rio and Akiyama Rin, he was like a primary school chicken, so he didn't understand why he joined this club to be tortured.

Looking at the glass products on the table, he resignedly picked up the used beaker to wash at the sink, and asked, "Then why don't you make some blue fireworks? Many people should buy them, right?"

"I tried to do a few, but then I gave up." Akiyama Rin had a helpless expression on his face, "It's too difficult to want it to be pure blue, I have to spend a lot of time to adjust and experiment, but so far I have I didn’t adjust the blue light without impurities. Coupled with the high cost of raw materials, my income from selling this kind of fireworks is too low.”

Speaking of this, the memory of setting off blue fireworks appeared in Akiyama Rin's mind.But the strange thing is, apart from the few times she went outside to experiment, she still clearly remembers setting off blue fireworks at the entrance of the store once, and it was a two-color one.

Akiyama Rin tried hard to recall this incident.Why would she put it at the door of the store?And it didn't seem to be night at that time, at least it wasn't completely dark.The most puzzling thing is that she seems to have directly ignited the effect piece at that time, and then manually threw it out.

Strange time, strange place, strange event.Akiyama Rin thinks this is probably the most outrageous thing she has done recently, but she really can't remember what she was doing at that time.She patted her feverish head, feeling that the low fever really made her a little out of shape.

However, she forgot two things one after another, and Akiyama Rin suspected that this might be related to her staying up late.While worrying that she would enter old age early, she thought about those pop-up advertisements that staying up late would affect her memory, and quietly set the flag that she would go to bed early tonight.
