Start with a Demon Cat, Give the Cat Gold Coins and You Will Be Invincible

Robin, a fourteen-year-old boy, came to a border town and began his fantasy journey. A cat that can spit out gold coins attracts adventurers from all over the world. Many years later, the king of adventurers was easily stepped on by a young man. "You're just a lucky boy." "Oh? Then guess, did I spread the news about the cat myself?" A talking cat, a treasure or a devil? If there is something that cannot be solved, just give the cat gold coins.
