The mystery of the golden coffin never actually closes, it just keeps expanding outward, dragging new factions and hidden agendas into the light. Season 3 leans into this: the princes of Tianqi aren't obstacles, they're proof that the original mystery was always bigger than one coffin. Lei Wujie, Xiao Se, and the others are still kids playing catch-up in a game designed by adults who've been making moves for years. The show's real strength is how it refuses to let any revelation feel like an ending, only a new question wearing a different face. You watch not because you expect answers anymore, but because the cast's bond is the only constant in a world where allegiances and loyalties fracture with every new player introduced.

The battle at Lei Family Castle has left the head of the Lei family dead and the Sword Deity fallen. Xiao Se, having forced his internal energy into use, now hovers close to death. To save him, his companions set off across the sea toward a mysterious Immortal Mountain, hoping to find a legendary deity there. Meanwhile, the conflict pitting the imperial court against the martial world rages on. This third season of the fantasy adventure runs 26 episodes as an ONA, mixing action with mystery.
