Interstellar Apocalypse: Sign-In, Copy, and Conquer the Galaxy

I, Ling Xiao, was once the first heir of the Interstellar Alliance. But after my wicked stepmother joined forces with my rebellious younger siblings to frame me, I was exiled to the interstellar wasteland. Then the apocalypse arrived. Mutant beasts ran rampant, and human civilization teetered on the brink of collapse. At my lowest point, I awakened the Sign-In Copy System! Sign in to obtain god-tier supplies, and copy mutant beast bloodlines, enemies' skills, and interstellar treasures!

My stepmother tried to seize my family fortune, so I copied her cunning and turned the tables on her. My rebellious siblings tried to take my life, so I copied the power of mutant beasts and crushed them all. A mysterious heroine, neither wholly good nor evil, became relentlessly entangled with me.

Starting with sign-ins in the wasteland, I copied everything, awakened the potential of a heaven-blessed prodigy, and clawed my way back from the brink to reclaim it all! In the interstellar apocalypse, where the strong prey on the weak, I, Ling Xiao, will sign in and copy my way across the galaxy, take control of humanity's fate, and become the overlord of the apocalypse!
