When the Demon King's Son Set Out to Conquer Earth

Yu Guo is a P13-level space sanitation worker. She has the classic ISTP personality: independent, rational, extremely self-controlled, and practical.

She likes taking on new challenges, so after becoming a legendary P13-level space sanitation worker, Yu Guo decides to quit.

On her last day at work, Yu Guo encounters an extremely rare cosmic storm. When her coworkers and managers all assume she's done for, she pilots the garbage-collecting spaceship she built herself back to them, having cleaned up every last bit of debris left by the storm.

No one knows that, among all that space junk, Yu Guo salvaged a spaceship more advanced than the most cutting-edge model of the era, along with a humanoid robot of extraordinary precision.

Yu Guo knows that her days ahead are going to get interesting again.

Eric is the son of Ao Rui of the Pegasus Galaxy. His mother is a valiant warrior, a great demon king feared by every race. His siblings inherited all sorts of her excellent qualities, each capable of standing on their own and earning a fearsome title.

Only him. Whenever people mention him, all they say is, "Oh, he's the least capable of the Great Demon King Aos's 108 children, right?"

Eric: Do you people have any manners?

Then one day, even his youngest sister earned a title of her own. Eric took a long, hard look at himself, left his personal planet, and boarded his beloved spacecraft for the Milky Way. He was determined to use his own abilities to successfully conquer a low-level planet.

But just after entering the Milky Way, Eric ran into a cosmic storm of a kind not seen in a century. The storm tore his beloved spacecraft to pieces and left him himself scattered in every direction.

The good news: he's still alive.

The bad news: he's lost his magic cube, affecting both his mobility and intelligence, and an evil woman named Yu Guo keeps taking him apart and studying him every day.

Then one morning, the villainess reached into his personal no-go zone. Eric couldn't take it anymore and sprang up. "You despicable lowly alien! If you dare disrespect me again, I'll have my mother capture every last one of you and send you to Ritan Star to mine elemental stones!!!"

Yu Guo slowly lowered her hand, her expression blank. "Lowly alien, huh?"
