Reborn as a Six-Year-Old Healer on a Monster Island

One moment, Irene was dead from a car crash. The next, she was a terrified six-year-old, adrift in a monster-infested ocean, narrowly escaping a prehistoric leviathan. Her new life seemed doomed before it even began. But a bizarre System intervened, offering a \"game test\" for survival. Choosing \"Physician\" wasn't just about healing boo-boos; it gifted her powerful spells, life-altering crafting abilities, and an terrifying \"Absolute Realm\" that bends reality to her will. She built a peaceful fortress on a remote island, aiming for a quiet, \"single-player\" existence. Now, a year later, thriving amidst her enchanted home, a mysterious door appears in her living room. The System, eager for her \"healing quests,\" has other plans, hinting at a multiverse populated by ninjas, pirates, and demon slayers. Can this \"nanny\" truly stay out of trouble when entire worlds need a doctor?
