The moment the minute hand deflected the number 6, Xu Xuanyue knew that she was late.

Thinking that Ke Yuhan and the others would definitely have to talk about themselves, she couldn't help but be annoyed.

But he was out of breath, and he was still a stop away from the library. In order to get rid of the fat on her stomach, she didn't dare to stop, and at the same time she was glad that she was wearing sneakers.

Xu Xuanyue looked up at the gloomy sky, only to remember that she didn't have time to bring an umbrella at all, and a few small drops of water hit the corner of her eye, and Xu Xuanyue sped up again.

Coincidentally, Xu Xuanyue stepped into the door of the library with her front foot, and the rain fell like a torrent outside her back foot, flying to wherever they could reach, and the entire entrance of the library became a water curtain hole in just half a minute.

The wind was blowing outside, and the doorman hurriedly pulled the door and urged Xu Xuanyue: "Come in, I have to close the door, the wind is blowing the rain in." ”

Xu Xuanyue trotted upstairs.

"I ...... I'm late. Xu Xuanyue panted, afraid of affecting other people's reading, so she sat softly on the bench next to Ke Yuhan, trying not to make any sound other than a heavy panting.

"5 minutes and 42 seconds late." Ke Yuhan looked at his watch and took back the book used to occupy a seat in front of Xu Xuanyue. "I'm not responsible for making up for the lack of time."

Xu Xuanyue brushed up the hair stuck to her forehead with sweat, tied up her braids, shook her head, and showed a confident smile: "Hehe, no problem, sister, I'm a genius, it's not a big deal to miss these few minutes." ”

Half an hour later.

"Oops!" Xu Xuanyue lay on the table, making a little temper and coquettish: "It's too difficult, I don't understand, stupid!" ”

There were disdainful glances from the people next to the voice, Xu Xuanyue hurriedly lowered her voice and looked at Ke Yuhan's embarrassed face: "Can't you say it in a simple and understandable way?" ”

Ke Yuhan lifted his glasses: "This is all very basic knowledge. ”

He also wondered, how could Xu Xuanyue make mistakes after repeating the formula that he could master and memorize in 5 minutes of preview.

When asked about the definition of a collection, she was able to pull the knowledge points she touched thousands of miles away.

This can't help but cause Ke Yuhan to think: Is it really appropriate for her to call me a dumb melon?

"What, it's obvious that you taught poorly."

"I question."

Then Ke Yuhan repeated the knowledge points again, and took out the notes and lent them to Xu Xuanyue.

Xu Xuanyue looked at his notes in a daze and was amazed.

Ke Yuhan used a total of black, red, yellow, blue, gray five colors of the pen, used to represent the difficulty of the topic, divided into grades, each definition below the simple memory method and their own understanding, example questions and difficulties are marked clearly, the first two pages of the notebook are used to write the table of contents, after the record is completed, the page number will be written, and then fill in the table of contents, the organization is too clear. Even the special problem-solving methods encountered when doing problems will stick the knowledge points to the notebook with post-it notes, and still use different colors to distinguish the difficulty.

Xu Xuanyue may have underestimated the definition of obsessive-compulsive disorder and logic mania before, but if Ke Yuhan can't fit these two words perfectly, then in comparison, he is simply living a crazy and chaotic life.

This also made a question pop up in her mind: "Ke Yuhan, why do you remember in such detail, I think you should be a genius, do you also need to sort this out?" ”

"Even the most memorable memories can be forgotten years later." Ke Yuhan said in a low voice, his tone suddenly heavy: "Not to mention subjects such as mathematics and physics, no matter how delicate they are, they are not excessive, just like life." So write it down, even if you think you'll never forget it now, but one day in the future, when those shadows that have been sealed in the grave crawl out again, you won't even have a strategy to deal with it, you can only rely on your nature to be ruthless, but it won't work in the slightest. ”

Xu Xuanyue saw the heavy dark circles under Ke Yuhan's lenses, and this sudden sentence made her heart numb, and she had no words to deal with, and she was speechless.

"You didn't sleep well, did you?" She only held back this sentence for a long time, but in the following time, she stopped complaining and complaining, and studied seriously little by little, even if the speed was still surprisingly slow.

When it finally reached four o'clock, Xu Xuanyue stretched out her arms and stretched her waist.

"Finally! Nailed it. She let out a long sigh.

"It's too early to get it done." Ke Yuhan corrected her rigor.

Suddenly, Xu Xuanyue realized a serious problem, and she asked Ke Yuhan: "Silly melon, did you bring an umbrella?"

"Well, I did." Ke Yuhan patted the side of the schoolbag.

"Where do you live?"

"Over there on Ergang Road." This answer is obviously not precise enough, but it is also deliberate by Ke Yuhan.

"Huh? That's not the way to go. Xu Xuanyue also counted on Ke Yuhan to give her a ride.

"What?"

When the two came downstairs, the rain outside the house still kept falling, and the rain didn't seem to get any lesser, and the road outside the house was also blocked by large and small vehicles.

"Can I still ride in a car?" Xu Xuanyue scratched her head and made trouble.

Ke Yuhan stretched out the umbrella: "Then I'll go first." As he spoke, he stepped out.

Xu Xuanyue grabbed him: "Where are you going?" Her face was full of horror, and she hugged Ke Yuhan's arm tightly like a child who was afraid of being abandoned.

"I'll go home." Isn't that obvious? Ke Yuhan thought to himself.

"No, no, no." Xu Xuanyue hugged more and more. "What should I do if you're gone?"

"Didn't you bring an umbrella?"

"Nope."

Ke Yuhan looked at the road outside the door, and then turned to the platform in the distance. "It seems that we have to go to the station on the other side of the road, and the road on this side is all blocked." He looked up again and observed the rain.

"Obviously, such a rain, such a small umbrella, is not enough to support two people. If I'm not mistaken, you want to squeeze the same umbrella with me? ”

Xu Xuanyue nodded frantically, her eyes full of begging.

"But in that case, we'll both be half wet."

"Are you going to leave me here alone and wait?"

"In terms of results, yes."

What kind of heartless computer is this? Xu Xuanyue secretly doubted in her heart.

"Then you're going to send me to the station opposite?" Xu Xuanyue asked again.

Ke Yuhan raised his head and calculated the distance, and then agreed. "But I want to warn you, even if you get there, you can't get in the car, after all, the traffic jam is very serious."

"Oh, I see." Saying that, Xu Xuanyue drilled under Ke Yuhan's umbrella, thinking that the traffic jam would always stop before the rain.

The two opened the door and walked out of the library, and the sudden wind blew Ke Yuhan's umbrella tilted, and he almost didn't hold it.

"Ah, stupid melon, hold it tight!" Xu Xuanyue shouted, sticking tighter.

The two of them walked to the opposite station with an umbrella in the wind, completely unaware of a little girl holding an umbrella but still soaking wet. Seeing them coming, she fled in a hurry and ran in the direction of home.

"Then how are you going to get home, silly." The two hid under the platform.

"I'll walk."

"What are you kidding? This rain! Xu Xuanyue stretched out her hand to catch the rain, but her palm was smashed painfully. Let's take a taxi, I'll pay, and you'll be paid for it on a rainy day. ”

"But the road hasn't been opened yet."

"It's coming." Xu Xuanyue pointed to the intersection, which had been evacuated.
