After transmigrating to an ancient mountain village, Jiang Chen transforms from a despised local rogue into the backbone of his family, capable of hunting ferocious beasts and identifying medicinal herbs. Blessed with a special system, he casts divinations every day to predict good and bad fortune, avoid danger, hunt game, and seek treasures, making his life increasingly prosperous. But the village landlord, the Chen family, sets its sights on the few acres of fertile land owned by the Jiang family. First, they frame Jiang Chen, then secretly lure the mysterious Black Mastiff King to him, intending to kill him. Relying on his superb archery and hard-earned boxing skills, Jiang Chen fights desperately against the giant beast in the mountains, risking his life to protect the villagers. When he is carried home with one leg broken, his elderly father throws away his crutch and stumbles forward, asking just one question: "You're not crippled?" Jiang Chen smiles and replies, "I'm not crippled."
