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

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

"Searching for a carpooler, please ...... later"

A radar-like pattern is spinning.

This intercity bus is carpooled by 10 people, and the cost per person is not 60 yuan, which is very cost-effective.

It quickly moved on the inter-city high-altitude track, reaching speeds 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 between vehicles by means of unmanned driving.

There used to be fools who wanted to show off their driving abilities in front of their own objects, and switched to manual driving in a non-emergency state, and the result was ...... Ash, of course. At a speed of 400 kilometers per hour, the car hit the railing of the high track, and not a single organ in the body was intact.

However, the railings made of carbon nanotubes were unscathed in car accidents, and the safety of high-altitude tracks became famous.

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

"You're so punctual, you don't come early for a minute!" Li Zhendong opened the door.

"Had a night's sleep in the massage parlor so was a little late......"

"Tsk, that's a great place for sexual encounters!" Li Zhendong had the expression of an animal on his face. This guy has been in the space city for a long time, and his whole body is like dry wood, as if as soon as he comes into contact with the opposite sex, he can rub and heat up and burn a raging flame.

Zhang Yuan said angrily: "Please, it's all aunts, where did you get the affair?" Should taste be so bad...... Can you please not talk to me about this as soon as we meet......"

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

"What?" Zhang Yuan's back was cold.

Li Zhendong looked excited, holding his mobile phone and waving it, "I talked about a girl these days, maybe a little story can happen...... If you look at the photos, it's still very good. ”

"Really?"

I took a look at the phone, and the avatar was a very cute girl, pouting, white and tender.

Chat History:

[F: You have a high salary, right? 】

[Li Zhendong: It's not high, money is not of much use to us, the main thing is to have a happy ......]

【Spaceship Photos】

[Li Zhendong's whole body suspension photo]

[F: Space is too fun, isn't it?] I dreamed of going to space once, but unfortunately the travel cost was too expensive. 】

[Li Zhendong: Risking your life to do this job, how can you say it's fun? In an environment without gravity, you can choke to death by drinking saliva, and there are really such cases! 】

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

[Li Zhendong: Of course, but I never relied on my father, I was admitted by myself. 】

【…… (10,000 words omitted from flirting • sister)]

[Li Zhendong: Look, I'm going to get on the spaceship, can you accompany me to watch a movie. I'm so old that I haven't dated yet. 】

[Female: Aha~ really fake? You don't have a girlfriend? 】

The woman's grinding and chirping, there has been no official reply, but it seems that she is moved.

Li Zhendong's eyebrows fluttered and flaunted: "You know how powerful my buddy is." Do you want to teach you how to pick up girls, this is the first trick, pretend to be pure, some women are good at this bite! They just like virgins! ”

Zhang Yuan frowned when he heard this.

"There is a second trick, I want to capture the old man."

"The third trick, the monkey steals the peach!"

"What...... Stealing peaches?! ”

Li Zhendong's tone became more and more excited, and his voice became louder and louder, "Oh, it's stealing hearts...... Think about it, even if you are gone, away from the earth, those girls still remember you. In the deepest part of their hearts, there is a corner for you, where the good times spent with you are buried. ”

"A year, ten years, a hundred years, the moment they die, the last words they spit out are your name...... And you're somewhere else in time and space. ”

"Don't you think this makes sense?"

I don't know why, Zhang Yuan was not shocked in his heart, and even felt a little like vomiting......

Zhang Yuan sighed, this buddy is good at everything, a high IQ, a genius, and a god-level figure who can get good grades casually.

The only bad thing is ...... Very sullen and bragging.

Zhang Yuan suddenly grinned: "Scumbag! ”

"I'll tell your mom!"

The air fell into a deathly silence.

Zhang Yuan repeated it as it was: "...... A year, ten years, a hundred years, the moment they die, the last words they spit out are your name? ”

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

"That's what you call it, right? Cool? Cool? ”

Silence again.

To a certain extent, Zhang Yuan can also be regarded as a talent.

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

……

Li Zhendong at the dinner table is a good son, he doesn't say a word, just eats silently.

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

This is also true, the spacecraft space is limited, the ecological environment is not good, it is okay to plant some plants, but it is impossible to cultivate pigs, cows, sheep, chickens, ducks, and fish in luxury. Therefore, all that is eaten in Space City is synthetic meat, that is, animal cell tissue in a petri dish.

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

He was chatting about some of the stories he had told about the design of the Earth Age.

“…… Your dad Zhang Qiming is really a genius, we can't think of a problem, he patted his head, turned his pen, and came up with it, it's like knocking medicine! ”

"Drugs?" Zhang Yuan couldn't help wiping the sweat from his face.

"He built most of the spaceship's control program, and so far only 212 minor bugs have been checked, which is really too difficult and too difficult......

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

"Is 212 still too little?"

"What you don't understand, the control engineering of the spaceship, one ring after another, layer upon layer, the more complex the system, the greater the risk. The Earth Era, with more than a dozen subsystems such as safety monitoring system, energy system, ecosystem, material circulation system, communication system, etc., as well as a small number of industrial plants, the complexity of 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 answer anything.

After a while, Zhang Yuan asked, "Can't the spaceship be faster?" ”

Li Cheng shook his head: "Seven thousandths of the speed of light is really fast. It can only be faster unless it is propelled by a large-yield nuclear bomb, which is expected to reach 3% of the speed of light, but our materials are far from being able to withstand the explosive power of a nuclear bomb...... And in the foreseeable future, it is unlikely that materials will appear resistant to nuclear bombs. ”

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

"No, not in recent years, or even in recent decades...... The entire global economic circle needs to recuperate for a while. ”

"This project is too laborious and costly, and even with the strong support of governments and the Deep Space Foundation, it will take a long time to recuperate before it can slowly recover."

"Regarding the special aviation tax, there is a strong opposition from the people, and several countries are also making a lot of trouble, and it is estimated that the ...... will be abolished."

Zhang Yuan wondered, "Could it be that we are a single group of deep space colonists?" ”

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

"The basic deep space voyage technology has matured, and rebuilding a second large colony ship will not be as costly as the first one, and perhaps, when the government has spare money, it is still possible to launch a second one."

"However, before the advent of new technology, it was difficult to increase the speed of navigation significantly. You don't expect the ships behind you to catch up to you. ”

Zhang Yuan nibbled on the chicken leg and paused slightly, he deciphered a key piece of information: the fat and oily Deep Space Foundation seemed to have no money.
