By the time Pu Tong and the others were about to go to a chemistry lab class, the rain had stopped.

The lab building is a bit far from their classroom, and if it's still raining, it's going to be a hassle.

After passing through the somewhat cold campus after the rain, everyone came to the laboratory, sat down in groups of two and began the experiment according to the requirements.

"It's so beautiful!"

"Huh?" Yu Yunjun heard Pu Tong's praise, and was a little overwhelmed for a while.

"It's so beautiful...... Yes, I can't stand it! Pu Tong's eyes looked at her as if they were glowing, making the girl a little dazed.

"Who are you boasting about?" Yu was a little embarrassed.

"Of course it's you...... Copper sulphate solution behind you! ”

Pu Tong lifted the test tube, looking at the touch of sky blue in it, and couldn't put it down.

"Why is it so good-looking?"

“……”

He must have made a mistake, right?

Pu Tong disagreed, shaking the crystal clear blue in the test tube quite intoxicated.

Why would anyone try to challenge the beauty of copper sulfate solution?

The chemistry experiment was very simple, and they finished it in the first half of the class, so that in the second half of the class, all the students began to configure the "potion".

The ready-made solution on the table was not dangerous, and the teacher didn't bother to deal with them, so he sat silently on the podium and watched them fool around.

In fact, many solutions are very good-looking and have their own characteristics.

Pu Tong is a pure copper sulfate solution pie, Yu Su also likes blue, and finally discovered this blue beauty under Pu Tong's bewitchment.

Iori Yukino prefers the purple-red potassium permanganate solution, and she claims that she doesn't like the litmus solution, which is also purple, but the potassium permanganate solution pushes people alone.

Lin Yuxi likes the light green ferrous chloride solution, which looks a bit like a green apple-flavored drink, of course, this thing must not be drunk.

"I suddenly thought of a story, do you want to hear it?" Pu Tong suddenly took a mouthful.

"Listen to the story!" Yu Suxi and Iori Xueno both said that they wanted to listen, and the remaining Lin Yuxi could only be left to them.

"Once upon a time, there was a blue-haired man and a silver-haired girl, and they loved each other, but the silver-haired girl wanted to turn red...... Finally one day, the man sacrificed himself for the girl's dream! ”

……

"Don't cry." The man with light blue hair looked at the silver-haired girl who had been crying in front of him, "Haven't you always liked red?" ”

"Yes, I love red," the silver-haired girl wiped away her tears, "but I don't want it to be built on top of other people's pain...... Especially you ......"

As she spoke, the silver-haired girl began to whimper again.

"It's okay, even if it changes, I'll remember you the same" The blue-haired man touched the girl's silver-white hair, "whether you love me or not when the time comes." ”

"Impossible! After a change, you will inevitably forget everything! This is the rule of this world, and it cannot be changed! The silver-haired girl suddenly became excited.

The man leaned down and kissed the girl lightly on the forehead, "Good, listen to me, sleep well, everything will be fine when you wake up." ”

The silver-haired girl finally fell asleep after the man's coaxing, and the blue-haired man stroked the girl's cheek and said, "I will make the world the way you like, don't forget that we once loved." ”

Soon, the silver-haired girl's hair gradually turned blood red, while the face of the man next to her gradually turned blue.

"Think of it as my last gift to you."

It was almost dark, and the girl, who had turned red, woke up and looked at her hands, her eyes dazed.

"In my memory, why can't I remember that blue shadow......

……

Pu Tong finished telling the story and looked at the three girls with different looks.

"Do you feel anything?"

"It's a little touching......" Yu Su secretly smacked his tongue, sacrificing himself for the sake of his beloved, no matter how you think about it, it's a great thing.

"But I'm a little confused about logic, what are the rules of the world? What does hair color determine? "Iori Yukino has a lot of question marks.

Lin Yuxi stood aside with a strange expression, as if she was a little guessing.

Pu Tong shook the test tube in his hand, "Actually, this story tells us: the blue copper sulfate solution can be replaced with silvery-white elemental iron, producing red copper and light green ferrous sulfate solution. ”

“？”

“？？”

“……”

Pu Tong ignored the resentful gaze of the three women, and admired the copper sulfate solution in his hand.

"Copper sulphate solution sauce! Your elemental iron mulberry is doing well now......"

Although he is a bit joking in it, in fact, knowledge is very interesting, and through the collision and fusion of ideas, many new and interesting things can also be produced.

In the eyes of some people, the understanding of knowledge is only the imprint of the ink of the book, or the information of the ears. But as you come into contact with knowledge, the more you will be attracted to it.

After chemistry class, the originally gloomy sky had completely cleared up at this time, and if it weren't for the water on the ground, it wouldn't have rained this morning.

The weather in spring is a bit warm and cold, and it is always impossible to predict it with common sense.

"Yo, why didn't you study with your copper sulfate solution at the same table?" After returning to the classroom, Yu Su's tone was a little displeased.

Forget if she can't compare to people, she can't even compare to a copper sulfate solution now?

Of course, the copper sulphate solution is very good-looking......

But in Pu Tong's eyes, she doesn't even have the charm of copper sulfate solution, which is too much.

"I'd still prefer a human tablemate."

"If only you knew!"

"And the copper sulfate solution sauce already has a single iron mulberry......"

"Get out!"

"That's where the fun of learning comes in."

Yu Xuan glanced at him, "I can't imagine that you like a person!" ”

What will happen to a wood like this out of tune and with a strange personality once you fall in love?

"Is it hard to imagine?"

"So, what would it look like?" Yu was puzzled.

Pu Tong thought for a while and said:

"You know what? Most of the anime episodes are 52 episodes, and one episode is broadcast a week, which means that it takes a year to broadcast the entire drama......"

"Being able to wait for updates on time every week, and being able to read a story for a year without interruption, I think it's really amazing!"

"If I like it for a year, I'm going to keep chasing it for 52 episodes until it's over. If I like someone, I will also chase her non-stop for 52 episodes until she leaves ......"

52 episodes, representing from the beginning to the end.

It's really a logically changing concept!

However, she seems to understand one thing, that is, people who are not easily tempted will be determined once they are tempted.

"But I don't have anyone I like yet!" Pu Tong stretched, "Of course, high school students study is the most important thing!" ”

"You'd better live with your potassium permanganate solution!" Yu Suyun couldn't help it, and gave him a little fist.

"Don't, it's not good to beat people in the show......"

Wait, it seems that there are no photographers lately.
