Lang rode a bamboo horse roaring

On the second day, the rock climbing team got up early and entered the mountain against the frosty morning fog.

The rock wall that Blue Mountain needs to climb is very remote. After crossing the valley and crossing a stream, it twists and turns, and finally sees its true face.

The rock wall is towering into the sky, with cracks all over the wall, and the upper half of it forms an obtuse angle with the ground. It is impossible to avoid gravity when climbing.

Difficult routes will not be easy to develop without the experience of the first comers.

Lan Shan stood not far from the rock wall and looked up thinking. He had seen pictures of this rock wall before, and had discussed with the coach what skills he would use to climb.

But photos and real objects are naturally incomparable.

Standing under the rock wall at this moment, Lan Shan glanced over the cracks, protruding rocks, and bevels, and quickly adjusted the strategy in his mind.

Bai Zhouyi stood beside him quietly, watching the rock wall with him.

After the two stood for half an hour, the sun shone into the valley, and today was fortunately sunny.

When the temperature rose to not so cold, Blue Mountain turned around to discuss with the coach and decided to start climbing.

He quickly changed into his climbing clothes, turned around and raised his hand to Bai Zhou.The clothes under the Lanshan protective suit were thin, and there was still snow on the ground. Bai Zhou felt cold even when he was wrapped in a down jacket, and he didn't want to know how he felt.But Bai Zhouyi didn't say anything, just stretched out his hand, gave him a light high-five, and said, "Come on."

Lan Shan's lips were pale with cold, but his smile was bright. He pointed to the formula on his left wrist and said, "Yes."

In order to prevent disturbing the climber's emotions, or being injured by accidental gravel falling, Bai Zhouyi retreated to the distant hilltop with the large group, and there were only a few people left at the bottom of the rock wall.

"Lan, what's this?" Before the climb started, the belayer saw the handwriting on Lan Shan's arm and asked, "Your new tattoo? Is your baby finally going to take the first step?"

Rock climbers are generally wild-minded, and tattoos are the norm, but Lanshan is very honest, not to mention tattoos, and they don't even have a pierced ear, but they are often caught and teased by the team members.

In fact, Lan Shan was also tempted, and wanted to get something tattooed on his body, but Bai Zhouyi said that tattoos hurt, and Lan Shan, who is so afraid of pain, must not be able to bear it.

Lan Shan murmured in his heart that he was afraid of pain, but said in his mouth that the tattoo would not be done.

Suddenly there were some marks on the good baby's arm, how could the protector not be curious.

"No." Lan Shan smiled at him and showed him his left arm, "This is much more awesome than tattoos, and this is the first time the theorem has been proven."

"Um." The belayer shrugged and said, "I don't understand these things, but if you say yes...I hope you take it to the summit."

Lan Shan said, "Thank you, I will."

After the chat, Lan Shan and the belayer stood face to face and checked each other's protective equipment. Lan Shan walked to the edge of the rock wall, clasped a concave point with his finger, took a breath, and said in a deep voice, "I request to climb."

The belayer said, "Climbing is permitted."

Rock climbing is a solitary practice suspended above the ground.

With no guidance, no idea where the next point would fall, and no one to talk to, Lanshan leaned against the crack in the center of the rock wall, using the friction of his arms to rub himself up little by little.

The above difficult routes are not easy to overcome. The climbers who came first will share their methods and give them as a reference for the younger generation. However, Lanshan is now facing an unknown route. He is the pioneer of this rock wall. For those who come, he wants to conquer it, define it, and take it as his own trophy, and give it to the lover watching from the mountain.

Lanshan is very light, and he can always leap like an antelope on the rocks. The onlookers only feel that gravity has no effect on him. He climbed up a few times and reached the middle of the rock wall.

"That big crack is a difficult point." The coach rubbed his hands beside Bai Zhouyi. They stood far away, so they could see the overview of the entire rock wall. The coach looked nervously at the small black shadow on the rock wall, and the blue mountain stood still for a few minutes. Seconds later, he jumped up quickly and broke out from the chasing of the crack. The coach wiped off his cold sweat and said nervously and thankfully, "He passed, thank God."

As soon as Bai Zhou didn't answer, he looked up at the rock wall, and the figure of Lan Shan had turned into a small dot, moving slowly on the boulder rock wall.Bai Zhouyi's expression remained unchanged, but he lightly rubbed the ring with his palm - it was given by Lan Shan before he put on the protective clothing. He said that he would exchange it back at night with a line called Zhouyi.

The blue mountain was like a kite, leisurely out of sight, and Bai Zhou held the ring and the rope that tied the kite.

As the spool twirled, his kite got higher and higher.

Higher.

Bai Zhou raised his head and muttered silently.

Go to the apex.

Opening up the route is a test for climbers and a torment for bystanders. The whole group is worried about Lanshan. During the period, when he made several mistakes, some people even exclaimed.

Fortunately, Blue Mountain did not disappoint them. The sun slowly moved up. At noon, after four hours and seven minutes of climbing, Blue Mountain grabbed the edge of the rock top and threw itself to the top.

The rock climbing team burst into cheers, Lan Shan heard it from the top of the rock wall, and turned around through the mist that had almost dissipated.On his left hand is written [Proven], and the sole of his foot is stepping on the top of the cliff that was first set foot by human beings.He stood up straight and waved to the people on the other hill.

Bai Zhouyi stood among the carnival crowd, looking extraordinarily stable, but the figure on the top waved his hand vigorously, waving some worry from his eyebrows, he was relieved and smiled without moving his expression.

"Great!" After Lan Shan landed, several people on the ground rushed over and threw him high into the sky excitedly.After throwing it down a few times, the protector gave him a big hug and asked, "How difficult is it?"

Climbers who climb a route for the first time are not only qualified to name the route, but also have the right to define the difficulty of the route.

After all, who knows the difficulty of it better than someone who has climbed it himself.

"Right." Lan Shan said, "The crack in the middle is more difficult."

"Yes." The protector laughed, "Your standard does not apply to other people."

Lan Shan also laughed, and the protector asked again: "Have you decided on a name?"

"LUNDI (Monday)." Lan Shan said the answer that had been decided long ago, but his eyes began to wander among the crowds of people in the distance, looking for something.

"But today is Sunday!" The protector said puzzledly, but he followed the eyes of the blue mountain, and when he saw the crowd in the distance, he understood a little, and asked with a smile, "Is his name 'Monday' right?" , is it such a simple reason?"

"That's right..." Lan Shan saw Bai Zhouyi, and he stood beside the thick-necked coach who was blushing with excitement, and smiled to himself again.

Lan Shan turned to the protector, smiled brightly, and said, "It's that simple reason."

Apart from Lanshan, there were two other team members who challenged the less difficult route, and they all succeeded before the sun set.

One day red-pointed three routes, and the team was filled with a joyous atmosphere. Back at the tavern, the coach waved his hand and said that today's drink is free, and he treated himself. As soon as he said this, the rock climbing team danced wildly, and Lanshan couldn't hold back. A bottle of beer, even if the alcohol concentration is not high, he was slightly tipsy when the show ended.

When he returned to the room, the handwriting on Lan Shan's wrist was a bit blurred. He felt a little regretful about it, and muttered whether he should really put that line of writing on his wrist or not. The drunk coaxed him to take a bath.

Lan Shan went into the bathroom, and Bai Zhou made a phone call to check whether the Chinese Academy of Mathematics had received the certificate.

After confirming, he called Pan Shi again.

After a few daily chats, Bai Zhouyi said, "I have two things to say."

"what?"

"I proved the Riemann Hypothesis."

"Really?!" Pan Shi's voice suddenly rose two degrees, and her joyful voice came along the phone line, "Oh my god, it's amazing, my son is a genius among geniuses!"

"Good luck." Bai Zhouyi said, "It needs to be verified before it can be completely confirmed."

Pan Shi understands him, she is not sure, Bai Zhouyi will not tell herself at all, she said cheerfully: "It's nothing. Then you can rest now, can you come back this year for the New Year?"

"can."

"Bring your girlfriend along." Pan Shi said with a smile, "It's such a festive event, we have to get together to celebrate."

Bai Zhou paused and said, "This is the second thing I want to tell you."

"Ok?"

As soon as Bai Zhou didn't speak, he turned his head and glanced at the porch. The bathroom door opened, and Lan Shan came out surrounded by warm white mist.Humming an out-of-key tune, he took out the hair dryer from the box, plugged it in, and tousled his wet hair.

Noticing Bai Zhouyi's gaze, Lan Shan raised his eyes and smiled heartlessly at Bai Zhouyi, looking innocent for his age.

"Hello——" Pan Shi asked puzzledly, "Can you hear me? Is the signal not good? Are you still there?"

Bai Zhouyi said, "Yes."

Then said: "Mom, it's not a girl, it's a boyfriend."
