"Pilots, we will enter the Tianlu section in twenty minutes. The train passes through the high-altitude areas of the Kokoxili, Kunlun Pass, and Tanggula Pass. The average altitude is more than 4,000 meters. Please pay attention to your physical condition and keep your mind relaxed. If you have any discomfort, please contact the train attendant..."

The noise-provoking carriage was quiet for a moment, and then it turned into a low whisper that blended together. The lights in the carriage were dimmed, and the continuous snow-capped mountains finally showed a true outline outside the window.

Yes pulled off his headphones and couldn't help but stretch out his fingers to poke the snow mountain through the glass.

He Xiu took off his other headphones and whispered, "Eat some chocolate."

The altitude sickness immediately, and high-sugar foods can provide some comfort to both the body and the mind. Yes nodded, and He Xiu stood up to reach the duffel bag above his head.

"Get a few more pieces." Yes said softly.

The girl sitting in front suddenly turned around and looked at Yes through the gap between the two seats. Yes looked as usual, but the girl turned around in panic a second later.

Yes sighed.

He Xiu grabbed a handful of chocolates and Yes tore apart one and took a bite.

The rich sweetness spreads on the tip of the tongue.

"Are you feeling uncomfortable?" He Xiu asked in a low voice.

Yes couldn't help but raise the corners of his lips, "Have you listened to the radio carefully? There are twenty minutes left."

He Xiu pinched his arm and said, "If you feel uncomfortable, you will speak. You have emergency medicine and oxygen inhalation tanks."

Yes nodded and continued to look out the car window.

The two men's jackets rubbed together, rubbing rustling sounds.

The train seat space was very spacious, but they still squeezed their arms. As they squeezed, Yes collapsed on He Xiu, pointing out the window, "Look at the snow-capped mountains."

He Xiu nodded, "I can't see at first glance."

The snow-capped mountains on the plateau are not only endless, but also pile up with snow that never melts all year round. The bottom of the mountain is a hard blue-black area, and snow gradually spreads upwards. When I first got on the bus at noon, the sun shone directly on the top of the snow-capped mountain. The snow exists arrogantly and unrestrainedly, a contradictory and tragic scenery.

He Xiu seemed to have countless thoughts in his mind, and he simply cleared his thoughts and tilted his head to Yes' forehead as if he was instinctively.

Yes snorted.

He Xiu couldn't help but kiss him again.

"What are you doing?" Yes lazily and shook the remaining half of the chocolate on his head, "Do you eat?"

He Xiu bit the chocolate into his mouth silently.

It has been more than a week since this trip. At the beginning, both of them were very excited. They wandered around and bought everywhere. He rode a rusty bicycle to carry Yes to taste all the noodles on a snack street. At sunset, he hummed a song and returned to his residence, and refused to part until the second half of the night.

But a few days later, they gradually bid farewell to the city and began to see endless roads, dry grasslands with cattle and sheep manure everywhere, mirrors of the blue and bright sky under the train, and countless temples.

The strong and unrestrained happiness on Yes gradually restrained. He didn't say a few words all day long afterwards, but just held his hand and curled the corners of his lips. The bright black eyes showed a sense of satisfaction.

Yes muttered while taking a photo in the Mirror of the Sky that there is nothing brighter in the world than here.

At that time, He Xiu was silently debugging the SLR, but he thought to himself that Yes's eyes were actually a little brighter than the Mirror of the Sky. Although it was only a little bit, it was indeed brighter.

He Xiu took Yes's hand and looked at the snow-capped mountains outside the car window.

When the two of them were dazed together, time seemed to pass faster.

In the white noise of the train running smoothly, He Xiu fell asleep in a trance for a while. When he opened his eyes, he felt a little dizzy and his chest was stuffy. He subconsciously looked at the time and quickly reached out to push Yes who was also asleep.

"Hmm?" Yes opened his eyes in a daze and frowned immediately, "Heart."

"The altitude sickness is coming." He Xiu quickly took out the oxygen inhalation tank. This thing was recommended by his classmates. If it weren't for the preparation for this trip, he wouldn't have known that some of his classmates were taking oxygen before going to bed every night before the college entrance examination. When he heard about it, he thought it was very fresh.

"This is yours." He Xiu looked at his cell phone for a long time, saw the Pikachu sticker on one of the bottles and jars, handed it to Yes and suddenly couldn't help but laugh.

"What are you laughing at?" Yes looked tiger-faced and his arm hit him.

"Nothing." He Xiu took apart another can, covered his mask and sucked it twice, then let go and said, "I'm really too naive now."

"You just say you think I'm childish and you're bad." Yes squinted his eyes and rubbed his fingertips on Pikachu, "What's wrong with sticking a sticker?"

"Not much." He Xiu smiled and covered his mask again.

The carriage became quiet, and after the altitude sickness, the people in the car were reluctant to speak. He Xiu took oxygen and the mild symptoms at the beginning eased, and he could still hear the little movement of Yes inhaling oxygen.

Perhaps the healthy heart is a gift from the system, but it is healthier and more energetic than his peers. Yes' heartbeat has always been a little faster than his, and now he is inhaling oxygen. The short sniffling sound makes people's ears itchy.

"Are you still feeling uncomfortable?" He Xiu couldn't help asking.

Yes took a hard breath, took off his mask and said, "I don't feel anything anymore."

He couldn't help but laugh, "Look at this car, it seems like he's being possessed by an evil person."

Everyone in the car was inhaling oxygen. Sitting in the front row and looking back, it was indeed a bit funny.

He Xiu looked at Ye Si's smiling eyes and gently shook his hand.

The train was at noon, but they left before four o'clock this morning.

Yes found the largest temple in the area, with ninety-nine steps in front of the temple. They held hands, clasped their palms one by one, put them down and then held their hands, and then bowed all the way.

He Xiu was an atheist. Even if he knew the existence of the system, he still could not equate time and space with gods. However, it doesn’t matter if he is not an atheist. Everyone should have pious faith in their hearts.

His belief may be a person or a period of time.

When they reached the top, both of them were a little panting. Yes' cheeks turned red, but instead of hanging around his neck like he usually did, he took his hand and pointed to the mountain.

"Look." Ye Si raised his eyebrows and said, his eyes full of youthful aura.

From darkness to dawn, there were three full hours, nine hundred and ninety-nine steps.

They all made wishes in the temple, and wrote them on the signs and left them in the temple.

He Xiu’s wish sign reads “My parents and Yes are safe and healthy.”

Yes wrote two wish signs, one of which stayed in the temple. It is said that he built a building for He Xiu for many years. There was another one. Yes secretly finished writing it and put it in his pocket. He Xiu could only pretend not to see it when he saw it, and he laughed and rushed to the station with him.

"Come on, laugh." Yes suddenly said in He Xiu's ear.

He Xiu came back to his senses and found that his phone was hitting above his face. Yes squeezed one of his arms, "Smile, take a photo."

He Xiu immediately raised the corners of his lips. Although he was a little stiff, he became very harmonious when he had more frames with Yes.

"It's so dark." Yes said and looked at the photo. It was dark all around. Without the flash on the camera, he could only use the light of the screen to sway a little on the faces of the two people.

"I took a lot of photos along the way, and I'll get it right away." He Xiu said with a smile, "I chose nine pictures to post on the third day of my trip, but now I'm starting to worry about it, and there are dozens of seed players."

Yes made a serious comparison, "I will choose the next day."

"What pictures?" He Xiu was a little surprised, "Are you not hesitating at all for so many photos?"

"Why do you have to hesitate?" Yes was a little confused when asked, "One Moments can only be posted nine times. Can't I post ten Moments to browse the screen?"

He Xiu: "..."

Yes sighed, "It's reasonable, it's not too much to come to the plateau and post ten circles of friends."

He Xiu's lips trembled, and finally couldn't help laughing. He turned his head and touched Hei and ate Ye Si's face.

Yes closed his eyes and snorted, "I'll tell you my boyfriend."

He Xiu's Adam's apple moved, "Yeah."

Yes: "You have exceeded your limit in the past two days, please restrain yourself."

"If you go to the plateau, you can't do anything." He Xiu whispered, and couldn't help but look at Yes's ear and kiss him.

"Fuck." Yes couldn't stand it anymore, as if he didn't see the glance in front of him sneaking through the crack in the seat. He turned sideways and took a bite on He Xiu's lips.

"It's okay to go to the plateau." Yes suppressed his voice, and his voice was too low, which made him feel a bit hoarse. "I will still kiss you when I stand on the top of the plateau."

He Xiu closed his eyes and said, "One word is determined."

There were still forty minutes before getting off the bus, and some people got up one after another to check their luggage, and the altitude was getting higher and higher. He Xiu was still worried and asked Yes again, "Does he feel uncomfortable in his heart?"

Yes closed his eyes, "You are so stubborn."

As he said that, he pulled open the zipper of the jacket, grabbed He Xiu's hand and put it on his chest. Before he could speak, he felt a certain head in front of him twisting back, and the two girls frantically used their elbows to each other.

Yes: "…"

A female voice said softly, "I'll go."

Another female voice said lower, "It turns out that the boys are still touching like this."

He Xiu: "..."

The first female voice paused, "It's okay, you can do whatever you want if you are handsome."

He Xiu was about to pull his hand back, so Yes pressed his hand and slammed his chest, as if he was demonstrating.

"I felt my heart beating very well." He Xiu said helplessly, "You should pay attention to it. You don't have to exercise more intensely these two days."

He said, without waiting for Yes to speak, and said, "I have already made an appointment to go up the mountain tomorrow. I will send half of it. Let's go the rest by ourselves, don't be stubborn."

"I know." Yes curled the corners of his lips and twitched again, "I just wanted to stand at the highest altitude and look at it, but I didn't say I wanted to climb up step by step. I'm sick."

He Xiu smiled.

In fact, there are quite a lot of people who are sick. Before coming out, he carefully prepared a guide. Many hikers not only hiked to the plateau, but even started cycling several cities away.

But Yes said: "Yes, but it's not necessary."
