Star Wars Hymn: from Junkyard to Interstellar Overlord

In 2526, the world's technology has undergone earth-shaking changes compared to 500 years ago. People discovered an alien creature called a crystal beast. As long as the crystals on their bodies are used as materials, mechas will be greatly improved. As technology improves, the gap between the rich and the poor will also be the same. Human beings seem to have degenerated and degenerated into the emperor's seal. Building society, and the emperor who owns half the galaxy exploits people, but these are far away from me... I am just an interstellar deliveryman working during the summer vacation, but I was involved in a conspiracy about mechas. By chance, I discovered that I actually have the blood of a crystal beast. How should I choose between exploited humans and sealed alien ancestors?
