On Sunday afternoon, as soon as Wu Bin got home and put down his schoolbag, Wu Bin's mother ran over and said, "The training is not hard, have you eaten well?" ”

"Didn't I take a photo and send it to your WeChat, the food is very good."

"I'm not afraid you won't have time to eat." Wu Bin's mother pinched Wu Bin's arm as she spoke, and found that there was still meat, so she nodded reassuringly.

"I'm going to a training camp, not a concentration camp, so I don't have time to eat." Wu Bin shook his head with a smile.

"Then how are you doing, did the teacher praise you?"

"Praised, praised, the teacher said that we were the best he had ever led." Wu Bin nodded and smiled.

"That's good." Wu Bin's mother nodded with satisfaction, "Oh yes, I'm discussing with your father, I want to invite your two physics teachers to have a meal, you go to school tomorrow and talk to your teachers." ”

"Oh, no, they don't miss you a meal."

"Hey, you look at you little conscienceless, without those two teachers, you can get this grade?" Wu Bin's mother poked Wu Bin's temple with her finger.

"I mean, they're definitely not going to take it, they never take gifts."

"Oh, I'm just going to give a gift, I just want to express my heart, thank them."

"It's not too late to invite the two teachers to dinner when I graduate, and they should be happy then." Wu Bin said after hanging his school uniform on a hanger.

"That's right, then you can invite the two teachers to eat something good, don't worry about the money."

"Got it." After speaking, Wu Bin put on a blue coat, put on his schoolbag, took two bags of cat food, opened the door and said, "Then I'll go to the small park first." ”

"As soon as I came back, I knew to look for the cat, you and your mother are not so close." Seeing that Wu Bin was about to go out just after he came back, Wu Bin's mother said with some blame.

"Nonsense, I'm the closest to you in the world, let's go."

……

When he came to the small park, Wu Bin shook the cat food twice, and heard a "salsa" sound in the grass of the small park.

A group of cats who heard the sound and moved "meow", "meow", "meow" and "meow" and surrounded them.

"Meow~" "Meow~"

Wu Bin, who also screamed twice, smiled and tore open the bag of cat food and sprinkled the cat food in the basin next to the bench.

Watching the cats grabbing food, Wu Bin sat on the bench and stretched beautifully, then unzipped his schoolbag and took out a chemistry book and a notebook.

His goal this afternoon, or rather this week, is still clear, which is to complete the knowledge network of chemistry.

This week, for the sake of chemistry, Wu Bin also went to Yu Xuguang's office, and took out his knowledge network to discuss it with the teacher.

Yu Xuguang also recognized after hearing this, and said that his teaching purpose is actually to let students understand that the most important thing in chemistry is not to memorize, but to sort out the context of knowledge, which can solve the big trouble that most students feel that chemistry knowledge is too "scattered".

After the last discussion, it came down to the experimental question, the final boss of high school chemistry.

For example, he now has this question in his hand.

How many steps are there between starting with ferrous sulfide and finally becoming ferric iron?

The equation of oxidation, is the reaction exothermic or endothermic, and why high temperatures? Why catalysts? What equipment in the industry absorbs SO3 and so on......

If you can answer a series of questions without pause, not to mention being proficient in experimental questions, at least in this high school chemistry, Wu Bin can be regarded as laying a solid foundation.

"Meow~"

A white cat was the first to finish eating, jumped up and rubbed Wu Bin's hand, and looked at Wu Bin with a pair of big eyes.

Wu Bin, who felt rubbed, also habitually stretched out his hand, touched the white cat's head, and then continued to solve the problem.

But after being touched twice, the white cat was so enjoyable that he stretched out his little paw and patted Wu Bin again.

So Wu Bin had no choice but to touch it twice.

But after a while, the white cat patted Wu Bin with his paws again.

"You clingy little one."

Wu Bin smiled helplessly, so he had to touch the white cat to do the question.

This made the white cat lie down beside him comfortably.

It didn't take long for all the cats to have their stomachs full and they gathered around Wu Bin.

Time passed slowly, and the swaying cat tails seemed to be teleportation devices, transmitting the lazy atmosphere of the afternoon to Wu Bin's brain.

Looking at the formulas and letters that were getting more and more blurred before, Wu Bin yawned and slowly fell asleep.

When I woke up, the sky was getting darker, and it was already evening.

'This situation is really a bit familiar......

Wu Bin, who rubbed his eyes, stretched his waist, looked at the half-finished question and a sleeping little black cat in his arms, and couldn't help but sigh: "It seems that this place is not suitable for studying in the future." ”

For Wu Bin now, even the soft big bed can't wake up his tiredness when studying, but in this park, tiredness can always occupy the high ground of his brain.

"But it's good to take a break once in a while~"

After gently hugging the little black cat to the side, Wu Bin stood up and wanted to take the schoolbag that was placed aside.

'Huh? This is? ’

When he was about to take the schoolbag, Wu Bin unexpectedly found that there was a piece of drawing paper pressed under the schoolbag, which immediately reminded him of the girl who couldn't speak last time, so he looked up and looked around, but no one else was there.

didn't see the girl, so Wu Bin turned around and lifted his schoolbag and pulled out the drawing paper.

This is ...... I? ’

Looking at himself surrounded by cats on the drawing paper, Wu Bin was a little surprised.

"So I was so handsome when I fell asleep?"

His face is angular, and even when he is asleep, he exudes a charm that makes you want to get closer.

Was it because I was disappointed last time that only my legs were drawn, so he drew another one for me today? ’

For this sudden gift, Wu Bin was naturally so satisfied that he couldn't be more satisfied.

'I must return the gift next time, but I don't know when I will be able to meet her again. ’

After thinking about it, Wu Bin said goodbye to the cats with his schoolbag on his back, and slowly walked out of the park.

When he got home, Wu Bin quietly returned to his room, walked to the desk, opened the drawer, and lifted a wooden board at the bottom of the drawer, revealing the "dark grid" below.

This was originally secretly made by Wu Bin himself when he was in junior high school in order to hide some "Yu-Gi-Oh" cards, which can be regarded as his own "treasure trove".

After admiring the painting again, Wu Bin carefully put the drawing paper in it and pressed it onto the wooden board.

Yes, he didn't plan to frame the painting or anything, because he felt that it was more suitable for him to enjoy alone.

"Bin Bin, are you back, wash your hands and get ready to eat~"

Outside the door, Wu Bin's mother's shouts rang out.

"Hey, it's coming~"

After answering, Wu Bin closed the drawer and walked out of the room happily.
