Rebirth: The Universe's Hidden Heiress - Chapter 4: Space Pirate

Because of his outstanding service and had enough merits, he was given a chance to become a human and unexpectedly transmigrated to the Interstellar era. But, how can he live his retirement days when has no money and everything? So, Qin An entered a reality talent show for idols and became an existence that everyone admires to.
