From Overlord To Multiverse. - Chapter 21: Labrinth.

Ye Feng was transported to a cultivation world, but unfortunately had no hope of cultivating immortality and could only live as an ordinary mortal. He only wished to live a peaceful life.Yet he didn’t know—The dog he adopted, because it ate his food, became a legendary demon king.The kitchen knife he casually forged became a peerless divine weapon, causing numerous experts to fight desperately for it.The young disciple he took in became an immortal lord that led an era, due to cultivating the techniques Ye Feng taught him.Even the skeletons he looked down on the most were ominous demon kings that suppressed countless worlds.Many years later, looking at the void shattered with a punch, Ye Feng murmured to himself: It turns out the peerless kings were myself all along…

Due to the whims of a higher-dimensional being called “The One”, the World of Terra ushered in a Monthly Apocalypse World Update Era.Every month, the World will draw a random monthly apocalypse world update theme, and the world will transform depending on what update theme has been drawn.Starting with a Zombie Apocalypse World theme, The World of Terra became infested with zombies!As a transmigrator, Zayne Voss, who thought he was living in a normal modern world, was caught up in this madness.Fortunately, he awakened the innate ???-rank talent, the Doomsday Life Simulator System![The Doomsday Life Simulator System allows the host to simulate your future and life in a given doomsday scenario.][For example, the simulator will randomly draw a doomsday scenario, and one of them might be a zombie apocalypse scenario. In that case, the host can experience life in a zombie apocalypse world.][Of course, it's not limited to that, as there are also different kinds of doomsday scenarios like the Helios Extinction Event, where the sun explodes and humanity faces such a world-ending scenario.][Not all doomsday scenarios are winnable and survivable, as some can be a dead end. However, your goal is not to win but to survive as long as possible and attain as many achievements as possible.][The longer you survive and the more you accomplish within that doomsday scenario, the higher your score will be. The higher the score, the greater the rewards you'll receive.][The rewards you can receive are mostly related to the power, skill, experiences, and talent that you possessed before the doomsday life simulation ended. They will be brought back to the real world so the host can gain power from doing life simulations.]-Ding![The host can choose one doomsday scenario from four of the following:][A. Helios Extinction Event][B. AI Singularity Rebellion][C. Global Ocean Survival][D. Acid Rain Catastrophe]Drawing the doomsday scenario called “Global Ocean Survival,” where everyone started with a wooden raft on a vast ocean, Zayne grinded in the doomsday simulation to become stronger in the real world!While everyone was still running away from zombies, Zayne had already eaten a Fairy Fruit from the Global Ocean Survival World and killed all the zombies around him!
