For five hundred years, the demon realm had no ruler, yet a prophecy persisted: *"When the heavens crumble and the earth splits, the new Demon King shall emerge—invincible, unharmed by any demon."* One day, an earthquake shook the demon realm. A hapless human, immune to magic, tumbled through a spatial rift. Kang Yu: *"…"* # *He looks weak as hell, but later…* # *He became the Demon King.* *** Xilai’er Ke’ang was troubled. Though he shamelessly became Kang Yu’s vassal after defeat, the lord’s attire was far too shabby. *No steed? Unacceptable.* After a fruitless search, he suddenly saw a brooding dragon reflected in the water’s surface. Xilai’er Ke’ang: *"…???"* *This’ll do!* —*Simp love interest × idol protagonist.* —*Lighthearted, fast-paced wish-fulfillment: sweet + crack humor + mindless adoration.* —*Edgy AF, worldbuilding based purely on author’s whims—demihumans only, atypical isekai.* —*Magic energy, nullification skills, and system-accompanied transmigration are tired tropes from old novels and anime. Plz don’t cry plagiarism.* **Author’s completed works:** - *"This Emperor Can’t, This Emperor Shouldn’t"* - *"Periodic Omega Syndrome"* - *"Severe Obsession"* - *"Six Cats Fight to Raise Me"* - *"Later, He Became a Cross-Dressing Icon"* - *"Later, He Became the Royal Wet Nurse"*
