The cycles of heaven and earth follow their order. A great tribulation is the way heaven evolves. This calamity, which lasts ten thousand years, allows no cultivator to survive the tribulation and attain immortality. Heaven and earth use the tribulation as a furnace to refine the old era. This is the end of an old age and the beginning of a new world. A cultivator who was lucky enough to evade the ten-thousand-year calamity encounters a world of cultivation where immortality is no longer the purpose of practice. Will he change the world, or will the world change him?
