Paine Lyon transmigrates into a primitive tribe as the ousted chief, robbed by his adopted son, weak. Near death in a cave, no food, land, or tribe members, he almost hurts Hui, a captured girl. He binds the "Lucky System": gaining women's following and rebuilding his tribe, he regains youth, improves combat, unlocks food, land, skills. Rescuing three sisters, Paine defeats chief Shan and achieves a comeback.
