After the Death of the Sword Emperor, He Actually Became My Destiny

The veins of purple marrow are buried deep, and a city is both a prison and a chessboard. The sickly young son of City Lord Shen Zi embarks on a dangerous and unpredictable path of cultivation. His sword of destiny is linked to a forgotten past. In this desolate world, everyone is struggling. In the end, is it annihilation that leads to the same goal through different paths, or is it a subtle variable that cuts through the eternal desolation? The missing empress, the arrogant chamber of commerce, the dormant beast realm, the forces in the city with their own evil intentions... Are all on the chessboard.
