I don't care how people in this world live, whether they are full or not, whether they can wear warm or not, or whether they have dreams or hopes. I don't care about their love and hate. But if I want to go to the sky, I need a complete higher industrial system, a complete set of relevant research institutes, the most advanced materials science laboratory and a large government that can coordinate all departments. It requires countless people with food and clothing to contribute their wealth to it, millions of higher intellectuals to contribute their minds, and tens of thousands of supporting manufacturers to provide the best parts. In short, a rich world and a great civilization can complete it. Ian A world reborn from the ruins. A round is about to usher in the end. A group of prisoners who fight for power and profit on the earth and fight for wealth and strength. A young man staring at the sky. Prisoners look out from the window of fate, mostly staring at the soil. Only one looked up at the stars.
