I am immortal and have unlimited lifespan. Are you going to kill me? I will not die until my time runs out. How much time do I have left? ∞. But I can only drift from one doomsday world to another, and in thirteen days I drift to another doomsday world that is taking shape or has already taken shape. Currently, we are imagining the first light and shadow mutation in the doomsday world, the second extreme temperature world, and the third fungus "True King".
