Collect the Doomsday

My name is Patient Zero and I'm an NPC in a dark game. This is the story of me traveling through different worlds with a stupid system and a hint sister, collecting apocalyptic elements and returning home. The Holy Grail War that has been completely cleansed, the ancient sky where gods and demons dance wildly, the Unrivaled Three Kingdoms where fierce generals are everywhere, the Primordial deification where the Heavenly Dao is unpredictable, the mass effect of the ten-thousand-year cycle, and the infinite space that completely fails to make people understand the meaning of life... Hello! I'm the supreme being in all your worlds. Don't casually send me a good person card!
