Murdered by the one person he swore to protect, Leo is reborn into a hellscape Earth. For five centuries, humanity has cowered in its last city, besieged by monsters from beyond the veil. At the city's heart stands the Tower of Ascension, a final monument to a dying world. But for Leo, death was just the beginning. He has a system—one that promises infinite power. To survive this apocalypse, he must climb the tower and become a god… or die trying.
