Lang rode a bamboo horse roaring

As soon as Bai Zhou walked into the waiting room, he said to Lan Shan, "Morning."

Lan Shan smiled at him, and the two of them were told to get in the car before they had time to say anything.

The two of them followed the rock climbing team and boarded the train in a mighty manner. Four people shared a sleeper berth. The rock climbing team took care of Bai Zhouyi and assigned the lower berth to him. They also took care of Lan Shan and Bai Zhouyi and assigned the other lower berth to him. Blue Mountain.

The team was full of young people who couldn't sit still. Before the train left, the two team members in the Lanshan dormitory went to play in other compartments, just to give Lanshan Baizhouyi time to be alone.

There were only two people left in the room, Lan Shan conjured up a candy and handed it to Bai Zhouyi.

"Motion sickness candy."

"I don't get carsick."

"Just in case." Lan Shan picked one out, leaned forward, and stuffed it into Bai Zhouyi's mouth.

Lan Shan's career meant that he couldn't eat sweets casually, but he looked at Bai Zhouyi with a smile, and smashed his mouth together, as if he also tasted sweetness.After Bai Zhou finished eating one slowly, Lan Shan took out a handful of colorful candies from his pocket and stuffed them into Bai Zhou's hand.

"Can't you take so much?" Bai Zhou looked down at the palm, the peach and grape flavored candies were on the top, looking very pink, "something to coax children."

"Coax you." Lan Shan folded his arms and squinted his eyes, "My boyfriend has a bad temper, so he has to coax you."

As he spoke, he took off his shoes, turned over and lay down, and muttered, "I'll sleep for a while."

Bai Zhou asked, "Want to accompany you?"

Lan Shan tilted his head a little funny: "Do you think those two buddies will never come back?"

Bai Zhou stopped talking and just looked at him.

Lan Shan closed his eyes for a while, and suddenly said with eyes on his forehead: "Don't look at me, I can't sleep anymore!"

Bai Zhouyi said, "I didn't see it."

Lan Shan squinted for a while, then opened his eyes suddenly, meeting Bai Zhouyi's eyes.

"I did not see?"

Bai Zhouyi said, "I didn't look carefully."

Lan Shan sighed: "If you don't study mathematics, you are really a good material to be a hooligan."

Bai Zhou was noncommittal.

Living in the same room with a boyfriend and sleeping in a separate bed is a very painful thing. Bai Zhou's gloomy eyes disturbed Lan Shan from falling asleep. He never admitted that it was because of shyness. He turned around and turned his head towards Bai Zhou The boat is gone.

Only then did Bai Zhouyi leisurely look away.

Ten minutes after departure, Bai Zhouyi received a message from his senior.

【I sent you. 】

Below is a picture, Bai Zhou took a look at it and asked.

【All? 】

[All are. 】

That page is densely packed, let alone thousands of data.

Bai Zhouyi's expression remained unchanged: [Are you sure? 】

[I can't be more sure, this page is not complete... But I want to remind you that many of these data have been substituted on the existing certificates, and they can't be proved. I didn't ask which certificates up.If you return without success in the end, don't blame me for finding a job for you. 】

Bai Zhou [No, thank you]

Bai Zhou clicked to open the big picture, scanned the values ​​that could not be pulled down to the bottom, took out his notebook, and began to try to prove it.

He was immersed in it, and he didn't move for hours without noticing the flow of time at all.Lan Shan woke up once in the middle, sat up rubbing his head and asked, "What time is it?"

Bai Zhouyi said, "Twelve o'clock."

Lan Shan nodded and said, "It's time to eat."

He looked at Bai Zhouyi again, the way he was writing in a hurry didn't look like he needed to eat, so he said sweetly, "I'm going to the dining car for dinner, do you want to bring something?"

"It's all right." Bai Zhouyi said.

Lanshan was ok and went out.

He finished eating quickly and brought Bai Zhou a baked rice.

Bai Zhou stopped writing and opened the package.

When he was eating, Lan Shan looked at him with interest. Once Bai Zhouyi immersed himself in mathematics, he would become a different person. He would become smarter and duller.

Lan Shan likes Bai Zhouyi in all appearances, especially the one in front of him, very cute.

There was a lot of laughter in the next car, Bai Zhou glanced at it, was spotted by Lan Shan, shrugged and explained: "They are playing cards...or maybe gambling, they are all similar, everyone is poor, and they can't lose much, just like a coach Don't stop."

As soon as Bai Zhou finished eating, he cleaned up the table, took out his notebook, uncapped the pen and asked, "Are you going?"

"No way." Lan Shan pouted his head and watched the nib of his pen slide neatly, and said, "I'm not suitable for gambling. I'm not lucky. I'll just see you write it."

The train is still passing through the wilderness quietly, the shadows of the trees are hurrying outside the window, there are some hoarfrost, and it is going to snow.

Lan Shan looked down, Bai Zhou kept rustling in one hand, and asked casually, "Do you understand?"

"I don't understand." Lan Shan shook his head bluntly, and he poked forward curiously, "What are those long strings of numbers? Is it the result of the calculation?"

"No." Bai Zhou lowered his eyes and said lightly, "You have to take it in and count."

Lan Shan opened his eyes wide in shock, the dense mathematical symbols on the paper gave him a headache.He asked, "All?"

Bai Zhouyi said, "It's all."

Lan Shan watched for a while as he calculated with a sharp pen tip. Just looking at it gave people a headache. He said, "Oh, do you guys who study mathematics have an extra brain than me?"

Bai Zhouyi said flatly: "I also often suspect that you rock climbers have four hands."

Or missing a nerve.

Seeing the towering rock wall, the first reaction is not "wow", nor "don't collapse", but "I must conquer it!".

During the high-speed operation of the brain, Bai Zhou took out a thousandth of a millisecond and sighed that it was a miracle of nature that he and Lan Shan could sleep in the same bed.

Bai Zhouyi had to think seriously, Lan Shan didn't bother him, he just propped his head to watch his movements quietly.But he really didn't learn this material, even if he just watched people work hard, he felt sleepy.Lan Shan stared at it for a while, then slammed his head on the glass.

"Hiss—" Lan Shan woke up from the pain rubbing his head, muttering curses.

Bai Zhou said, "Lie down and sleep."

Lan Shan said, "I want to be with you."

When Bai Zhou saw that he couldn't lift his eyelids, he felt that he would hit the glass again, and said, "Then come to my side."

Lan Shan passed by, Bai Zhouyi wasn't coffee, and being next to him couldn't stop the drowsiness, but when he fell asleep, it was better than hitting the glass with his head on Bai Zhouyi's shoulder.

Lan Shan leaned on Bai Zhou's shoulder and slept for a long time. During the period, the team members in the same room came back once and saw them sitting on the same bed, one writing something and the other falling asleep. He sighed that the young couple had a good relationship, and went out again.

Bai Zhouyi didn't know how long he had been calculating, his world was only left with the calculation formulas written by his pen, and the slight breathing sound on his left shoulder.

Another failed attempt.

Bai Zhou stopped writing in the middle of the process, looking at the illogical proof.

There is no need to continue the calculation. If the value is wrong, the formula cannot be established.

He let go of the pen, rubbed the center of his eyebrows with his right hand, and belatedly noticed that his shoulders were numb.

Looking down, Lan Shan was still leaning there, with soft black hair and slightly open mouth, sleeping soundly like a child.

Bai Zhouyi could barely feel the disappointment of failure, too many times, there was no time to feel emotional again and again, but he felt a little comfort at this moment.He was not in a hurry to continue trying, and gently pinched Lan Shan's cheek.

As soft as expected.

Before Bai Zhouyi had time to pinch a few more times, there were several shouts of surprise from the next room. Bai Zhouyi caught the word "snow" in his half-baked French. He let go and turned his head to look out the window. The clouds were overwhelmed. , Flying goose feather heavy snow outside the window.

The black and green in the wilderness were replaced by plain white in just a few seconds. The train flew into the cave at this moment, and came out a few seconds later. The world has turned into pure white, as if it has entered winter from late autumn.

Lan Shan was woken up by the noise of the rock climbing team, leaned on Bai Zhou and rubbed his eyes, looked out lazily, and was surprised to find the snow and ice outside, he said in a low voice: "Oh——"

Children in the south are always curious about Xue. Even if it is not the first time they see Xue, both Bai Zhouyi and Lan Shan stare out the window.

Bai Zhou followed him and said, "It's so beautiful."

Lan Shan leaned forward, stuck himself in Bai Zhou's arms, and pressed his hands against the glass, the coldness of the snowy day penetrated through a thin layer, freezing his palms.He withdrew his cold hand, put it in his pocket, and yawned.The surprise of seeing the snow was over, and the drowsiness flooded up again. Lanshan also gathered people into a ball, curled up in the heating of the train, and shrank next to Bai Zhouyi's constant body temperature, closed his eyes again, and fell asleep peacefully. .

Bai Zhouyi also looked away from the snow field, looked at his watch, and realized that he had counted four hours.Slow exhaustion surged up, and Bai Zhou began to think about whether he should also take a nap, and it would be better to hold Lanshan.

He flipped through his notebook, and there were only two free pages left.He then selected a number from the data sent by his senior, and decided to rest after writing the notebook.

He took out a candy from his pocket, threw it into his mouth, and began to write with the sweetness in his mouth.

The snow was falling, the blue mountain was sleeping on his shoulders, and Bai Zhouyi was in an extremely calm mood. It seemed that this was just another failure like before.

But this time he wrote for an extra long time. After turning the page, Bai Zhou sat up straight, and he had reached a stage that he had never tried before.

His brain and body began to tremble unconsciously. At that moment, he seemed to be chosen by heaven.

He had a hunch it would work this time.

Bai Zhou was in a hurry, the pause at the end of the characters was no longer stable, and he flew up scribbled.

He quickly ran out of two pages and had to continue writing on the notebook cover.But soon the cover was also full.

He clutched the napkin, and at this moment he connected with an ancient mathematician, scribbling calculations on the flimsy tissue.Paper towels run out quickly.

Bai Zhou spun the pen twice like a trapped animal, and hurriedly took out his mobile phone, but many symbols were difficult to express on the keyboard. His brain was trembling with excitement, and the calculations had already rushed past, and he ran to the end of the proof, but The screen is still stuck at mid-range.This made Bai Zhouyi extremely irritable and rarely anxious.

Lan Shan was awakened by his increasingly violent movements, sat up straight, rubbed his eyes, and asked in a daze, "What's wrong?"

Bai Zhou pressed the keyboard cracklingly, and said briefly, "Is there any paper?"

"Wait." Lan Shan realized something from his impatience, straightened up, hurried to the next door to knock on the door, and asked, "Does anyone have more paper?"

He came back two seconds later and shook his head at Bai Zhou: "They don't even have tissues."

Bai Zhou hummed briefly, but didn't look up. He was already a little stunned, his fingers were trembling uncontrollably, numerical values ​​and theorems whizzed through his mind like countless trains, he was like an over-loaded machine, in urgent need of output.

Lan Shan scratched his head, he was still sleepy, but he reluctantly proposed a solution: "Why don't you write it on your hand first?"

Bai Zhouyi said, "Not enough."

"Then..." Lan Shan sat down next to him and spread his hands, "You can also write on my arm."
