Zhang Yuan took out his mobile phone, clicked on the self-service taxi-hailing software, and entered his destination voice.

"The destination, Donghai City, has a mileage of about 412 kilometers."

"Search for carpooling objects, please wait..."

A radar-like pattern is rotating.

This city bus costs 10 people to share a car, and the cost per person is not 60 yuan, which is very cost-effective.

It quickly drove onto high-altitude tracks between cities, with a speed of up to 400 kilometers per hour. This speed is no longer something that ordinary humans can control, so it is necessary to strictly maintain the distance of the vehicle through unmanned driving.

There was once a fool who wanted to show off his driving ability in front of his partner, and switched to manual driving in a non-emergency state, but the result was... of course it was gray. The car hit the high-track railing at a speed of 400 kilometers per hour, and no organ on his body was intact.

However, the railings made of carbon nanotubes are unscathed in car accidents, and the safety of high-altitude tracks is therefore well-known.

An hour later, after getting off the bus, Zhang Yuan took the subway to reach his destination.

"You are really on time and don't come early for a minute!" Li Zhendong opened the door.

"I slept in the massage parlor, so it was a little late..."

"Tsk tsk, there is a good place for a romantic encounter!" Li Zhendong looked like a livestock. After staying in the Aerospace City for a long time, his whole body was like dry firewood, as if he could rub and heat up when he came into contact with the opposite sex, and burned out a raging flame.

Zhang Yuan said angrily: "Please, they are all aunts, where did you get the romantic encounter? Do you have such a bad taste? Can you not talk to me about these things as soon as you meet..."

"Zhang Yuan!" Li Zhendong's eyes suddenly became serious, as if something was brewing.

"What are you doing?" Zhang Yuan's back chilled.

Li Zhendong looked excited and waved his cell phone, "I have talked to a girl these days, maybe some story can happen... You can see the photos, it's still very good."

"Yeah?"

I took my phone and saw that the avatar was a very cute girl, pouting, white and tender.

Chat history:

【Female: Are you very high salary?】

[Li Zhendong: Not very high, money is not very useful to us, mainly to live happily...]

【Spaceship Photos】

[Photo of Li Zhendong's entire body floating]

【Woman: Space is so fun! I dreamed of the last time I went to space, but unfortunately the travel cost was too expensive.】

[Li Zhendong: How can you say this work is fun at risk of your life? Without gravity, you can choke to death even if you drink a sip of water. There are really such cases!]

[Female: Is your father also a worker in Space City?]

[Li Zhendong: Of course, but I never rely on my father, I passed the exam myself.]

[……(Omitted 10,000 words of flirting with girls)]

[Li Zhendong: Look, I'm going to get on the spaceship. Can I watch a movie with me? I've grown up and haven't had a date yet.]

【Female: Ahha~ Really fake? Do you don’t have a girlfriend?】

The woman was so rude that she had not yet responded, but she seemed to be moved.

Li Zhendong showed off with a roar: "You know how good your buddy is. Do you want to teach you how to pick up girls? This is the first trick, pretend to be pure, and some women will be good at this! They like virgins!"

Zhang Yuan frowned when he heard this.

"There is another move, playing hard to get."

"The third move, the monkey steals peaches!"

"What...steal peaches?!"

Li Zhendong's tone became more and more excited, and his voice became louder and louder, "Oh, it's a heart-stopping... Think about it, even if you have left and left the earth, those girls still care about you. In the deepest part of their hearts, there is a corner for you, where the wonderful time you spent with you is buried."

"One year, ten years, one hundred years, the last words they spoke out were your name...and you are in another place in time and space."

"Don't you think this matter is meaningful?"

For some reason, Zhang Yuan was calm and even felt a little tempted to vomit...

Zhang Yuan sighed, "A man is good at everything, a high IQ, a genius, and a god-level figure who can achieve good results at will."

The only bad thing is... it's very introverted and bragging.

Zhang Yuan suddenly grinned: "Scumbaby!"

"I will tell your mom!"

The air fell into a silence like death.

Zhang Yuan Yuanma repeated as it was: "...A year, ten years, one hundred years, the last words they spoke out were your name at the moment they died?"

"Li Zhendong! Li Zhendong! Ah, I'm going to die."

"Is that true? Are you happy? Are you happy?"

Silence again.

To a certain extent, Zhang Yuan is also considered a talent.

Li Zhendong also sighed and stared at the ceiling: "I just want to kill you now, beat you to death, really!"

...

Li Zhendong on the dining table was just a good son, and he didn't say much, just ate silently.

Li's mother was very kind and kept asking Zhang Yuan to eat more, saying that "you can't eat the original meat when you go to space" and "this big chicken leg is real local chicken", exactly the same as my sister-in-law's words.

This is true. The spacecraft has limited space and the ecological environment is not very good. It is no problem to grow some plants, but it is impossible to cultivate pigs, cows, sheep, chickens, ducks, and fish in luxury. Therefore, the food in the space city is all synthetic meat, that is, the animal cell tissue in the petri dish.

Li Zhendong's father Li Cheng and Zhang Yuan's father are colleagues in Space City.

He was constantly talking about some stories about his past designs of the Earth Age.

"...Your father Zhang Qiming is such a genius. A problem we can't think of. He slapped his head and turned the pen to figure it out. It was like he was hitting medicine!"

"Put drugs?" Zhang Yuan couldn't help but wipe the sweat from his face.

"Most of the control programs of the spacecraft were built by him. So far, only 212 small bugs were checked, which is really too difficult..."

"It's a pity that I left too early, but it's a pity..." Li Cheng was in a complicated mood and even drank some wine.

“Is 212 still a small number?”

"You don't understand that the control engineering of spacecraft is one after another, one layer after another. The more complex the system, the greater the risk. Earth Age has more than a dozen subsystems such as security monitoring systems, energy systems, ecosystems, material circulation systems, communication systems, and a small number of industrial factories. The complexity of the control engineering is far beyond your imagination!"

"Software and hardware complement each other, and the difficulty of software does not have to be low in hardware!"

Neither young man could take anything to say.

After a while, Zhang Yuan asked, "Can the spaceship be faster?"

Li Cheng shook his head: "The speed of light of seven thousandths is really fast. It can only be faster unless it is pushed by a large-equivalent nuclear bomb. It is expected to reach 3% of the speed of light, but our materials are far from bearing the detonation power of nuclear bombs... and in the foreseeable future, it is impossible for nuclear bomb-resistant materials to appear."

Li Zhendong also asked, "Dad, will we build the next colonial ship after we leave?"

"No, it shouldn't be true in recent years, or even in recent decades... the entire Earth economic circle needs to rest for a while."

"This project is too exhausting and financially damaged. Even with the strong support of various governments and the Deep Space Foundation, it will take a long time to recover before slowly recovering."

"There are strong civil objections regarding special aviation tax, and several countries are also making a big fuss. It is probably going to be cancelled..."

Zhang Yuan asked in confusion: "Are we a separate group of deep space colonists?"

"Not necessarily, as for what will happen in the future, who knows?"

"The basic deep-space long-distance technology has matured. Rebuilding a second large colonial ship will not be as expensive as the first one. Perhaps, when the government has spare money, it is still possible to launch the second one."

"However, it is difficult to significantly increase navigation speed before new technologies emerge. Don't expect the spaceships behind you to catch up with you."
