The 58-year-old Wang Dashan was reborn as a 15-year-old in Qingfengguan in Xiaoxing'an Mountains. His first goal was to save his grandfather Wang Zhengfeng who was killed by bandits while protecting the villagers in his previous life. Relying on the memory of his past life, he decisively killed the gangsters with his sword, making up for the lifelong regret of not being able to support his son. Since then, Wang Dashan and his Taoist grandfather have depended on each other. Relying on their familiarity with the mountains and their understanding beyond the times, they hunted blind bears, hunted wild boars, drove mountains to collect ginseng, and even dug up gold nuggets. They also accidentally discovered a Japanese military fortress.
