Anime Crossover: Demon King of Another World, Hunting Down the Fourth Calamity

After transmigrating into a world of anime crossovers, Luo Chen binds himself to the System and becomes, from the start, the ruler of a Demon King's castle, a world blending the settings of Sleepy Princess in the Demon Castle, Genshin Impact, and more. When a human princess is brought to the castle as a hostage, she neither cries nor waits for a hero to rescue her. Instead, she steals keys, pulls out a needle from a porcupine's back to use as a pin, plucks a demon bear's fur to stuff a pillow, then makes herself a sleep pillow and falls asleep in an instant. Hidden in the shadows, Luo Chen can only sigh: "Are you the Demon King here?" Ying, an otherworldly Traveler who has slept for hundreds of years in a forbidden zone, awakens. They should be brother and sister, but the System has altered things so they're sisters. Her first words are: "My sister was taken by the gods." Luo Chen rubs his temples. "The records say you only have a brother..." A System mission pops up: Stop the Fourth Calamity from destroying the current world. Luo Chen crushes the panel and looks out the window at columns of light bringing down "players" by the hundreds. Poorly equipped and fanatical, they attack anything that moves and click dialogue boxes whenever they see an NPC. He turns to the princess, who is snoring away, and says, "Wake up. Your hero is here, except this time they're here to tear down my house."
