Jiang Chen, a modern-day overworked corporate drone, travels back in time to an ancient era of famine and becomes a notorious rogue in Sanshan Village, known for stealing his family's winter provisions to curry favor with his scheming fiancée. With his father's leg broken and the family completely out of food, Jiang Chen unexpectedly obtains a mysterious tortoise shell that reveals daily opportunities hidden deep in the mountains. Following its guidance, he finds snow hares, raids pheasant nests, digs up century-old gastrodia, and spears a giant fish in a deep pool. Not only does he put meat on his family's table, but he also reveals an astonishing talent for archery. Jiang Chen decisively breaks off his engagement to the parasitic mother and daughter, uses his strength to intimidate his fair-weather friends, and gradually sheds his reputation as a good-for-nothing. Taking responsibility for supporting his family, he leads the Jiang family to rise from adversity amid the bitter winter and chaos of troubled times.
