The next morning, four o'clock.

Zhang Yuan woke up from his sleep and slept well last night.

I don't know if it's a happy time or a painful time.

He stroked the girl's silky hair and prepared to leave.

It's a strange feeling, it's not very comfortable.

After putting on his clothes, Zhang Yuan wrote a line of text on a sticky note on the bedside table: "I'm leaving, goodbye." ”

"I wish you a happy life and a long life of two hundred years."

Glancing back at the sleeping girl, he turned to leave the room.

In fact, Han Ziyue had already woken up, she just buried her head in the pillow and cried secretly, unable to stop at all.

There are some things that I know, but when they really come, they are still very uncomfortable.

What does it feel like a moth to a fire?

I couldn't help but pounce on it and burn myself to ashes......

It's still early, the sun hasn't risen in the east, and the streets are empty.

Strangely, there was a yellow-haired puppy that kept following Zhang Yuan, following in unison. Judging from its coat color and size, it should be a stray dog, very thin, and its life is not good.

Zhang Yuan thought about it and bought two sausages from a nearby automatic retail machine and fed them to the poor puppy.

Unexpectedly, after eating, it trotted all the way and followed Zhang Yuan again, and seemed to know which person was good to it and which person was not good to it.

In 20 minutes, Zhang Yuan returned to his bedroom, took all his luggage, and cleaned the room where he had lived for 19 days.

There are a lot of stories that happen here, which is unforgettable, and it is my last time on earth.

The puppy had been lying in the doorway watching.

Zhang Yuan said with a smile: "I'll help you take a little bath, if you clean up your hair, you won't necessarily be killed after being caught by the chengguan." If you look good, you may be able to find a beautiful woman to take you in. The girls here are very caring......"

The puppy has always been very obedient, and when it comes to bathing, its tail keeps waging.

Zhang Yuan estimated that the dog was probably abandoned here, otherwise it would be impossible to be so well-behaved.

Next, after taking a bath, Zhang Yuan couldn't help it more.

Close the door to the dormitory, grab all your luggage and prepare to leave, the dog continues to follow.

I took the rest of the sausage and fed it, but I still refused to eat it, so I followed it quietly.

Finally, I was about to leave the school gates.

Zhang Yuan said: "It will be more dangerous for you to run into the city, so it is better to stay in school." You can find food here, and you won't be killed. ”

Persuasion is ineffective.

Zhang Yuan squatted down, picked up a stone, and pretended to hit it.

The dog finally stopped, and it just squatted on the ground, as if it was stupid, with a stupid head, unable to understand the contradictory behavior of the person who had to feed it one moment and hit it the next.

Zhang Yuan turned his head and was slightly sorry in his heart, perhaps, this dog once pinned his hopes on him, but there was no way. What you can't promise, there's just no way.

Whether it's life or a dog's life, it's like this, you have to get used to being let down, to be lonely, to be banished, to wander, to be abandoned.

That's a person's life.

Seeing it walk back to campus, Zhang Yuan breathed a sigh of relief and sent a text message: "Li Zhendong, are you awake?" Where do you live? ”

"I'm in the cafeteria, and you're having breakfast. Do you think I'm just as chaotic as you are? I enjoyed my last night on Earth, didn't I, such a beautiful girl...... Wow! Li Zhendong chattered a lot.

"Bring me two buns."

When the two met, Li Zhendong had a gossipy look on his face.

"How does it feel? Isn't it very lively! ”

"Where is what you say, let's go!" Zhang Yuan was in a bad mood and was too lazy to say.

dragged the suitcase to the check-in desk and went through one security check after another.

The safety of the space elevator is strict, similar to that of previous aircraft, liquids, flammable, explosive and sharp objects are not allowed. And there are several medical examinations, and some patients with serious infectious diseases are not allowed on the ship.

After passing the physical examination, the staff quickly arranged for them to get on the space elevator batch.

【Identity number 330841244...... Zhang Yuan, your seat is 17-3-D, elevator lot 2264-8-3-1246......]

Zhang Yuan turned around and asked, "Isn't there any family to see you off?" ”

Li Zhendong smiled heartily: "No...... My mom was going to cry again when she saw me. Still won't let him come. ”

"That's right."

A lot of messages have been sent on the phone.

"Zhang Yuan, have a good trip!"

"See you on the spaceship!"

"Have a safe journey!"

Zhang Yuan received all kinds of condolences from relatives and friends, but Han Ziyue was missing. Maybe she's still sleeping; Or maybe as I said last night, there is no future anyway, and there is no need to contact more in the future, so that last night will be the most profound memory.

"Dingdong - 1246G batch passengers, please note that the space elevator you are riding in is about to start......"

As the minutes passed, he didn't dare to slack off and lined up in the line.

All the astronauts were quiet. Li Zhendong behind him lowered his head, not knowing what he was thinking.

Zhang Yuan raised his head and looked at the endless sky, the sky was gray, revealing a trace of light.

“…… The total length of the space elevator is 36,000 kilometers, which is more than 4,000 times that of Mount Everest, the highest peak in the world...... The main material carbon nanotubes, with a tensile strength of 62,000 MPa and a fracture length of 46,000 kilometers under the earth's gravity, are fully capable of meeting the needs of space elevators......"

“…… Human beings are very small, human beings are very great, technology changes the world, science and technology make the future! ”

The documentary on the big screen is playing on a loop, relieving the boredom of the queue.

In stark contrast, there is a group of passengers who are about to go to space. Men and women screamed and cheered. For them, it was a very memorable and proud trip of their lives. Tourists are noisy and talking, praising the greatest building in human history.

“…… We will finally open an unprecedented era of great stars. ”

Zhang Yuan has watched this documentary countless times, and he can almost memorize all the lines.

But he still saw the end all over again, and watched it carefully, this should be the last time in his life.

There are so many memories, no matter what the details, they are full of memories.

This is the home planet, the eternal home planet.

"Drip", through the gates.

"Have a nice trip."

The electronic tone is still the same cold tone, which is not so comfortable to listen to in the ears.

When he walked around that corner, Zhang Yuan couldn't help but wipe his eyes with his sleeve.

Then, I wiped it a second time with my sleeve.

This action is exactly the same as what Ye Kaifu did at the beginning.

A tear welled up from his eye socket and dripped down his cheek to the ground.

After this step, they no longer belong to the earth.

Farewell.

Hometown.
