Reborn into 2020 as a university student in America, Lin Yu'an vows to save his wife from the accident that destroyed her in his past life and build a better future for his family. Competing on "Alone in the Wilderness," he gains worldwide fame for his bow-hunting prowess against black bears. Surviving Alaska's merciless sub-zero temperatures, Lin Yu'an constructs log cabins, trains hunting dogs, and hunts with a Winchester Model 70 Rifle across dangerous wilderness. Determined to defend his championship, he returns to face extreme challenges and adopts an orphaned polar bear cub. Lin Yu'an then pursues adventure at sea, purchasing a single-handed sailing boat to hunt and explore across global waters. His expeditions span from deep-sea tuna fishing to diving for lobsters and Nautilus creatures—crafting a lifestyle that mirrors the endless discovery of "Animal Crossing."
