Global Cataclysm: Starting with Life-Years as Currency and Immortality

The abyss descends upon the world, demonic realms run rampant, and the endless void erupts... When three suns hang high in the sky, when worlds as numerous as grains of sand collide... where do we go from here? Will the gods raise their thrones? Will demons lurk in the abyss? When the firmament falls, I will shoulder the fallen pillar of heaven and become its new support. My name is Song Tian! Song Tian, as in, sending you straight to the western heaven!
