A Dart Escort with One Sword Across the Mountains and Rivers

A broken sword that can speak but cannot kill leads four generations of the down-and-out Lu Family Escort Agency on a century-long escort mission. At first, they transport goods. Later, they transport the truth. At last, they escort the Sword Immortal himself to complete the seal he left unfinished all those years ago. The highest powers in the martial world maintain their authority by dividing up the Sword Immortal's remains, while the Martial Prohibition Bureau sustains the seal on the Celestial Tower by consuming the martial arts of the jianghu. To repair itself, the sword spirit must reclaim the remains, but restoring them will also shake the seal. Every generation of the Lu family must choose between family, the sword spirit, and the world.
