Deadly Reincarnation

(No female lead, one male protagonist, inexperienced writing, please bear with me) What exactly does the Ascension Game ascend to? Who are the actual players? Can you really escape after clearing every instance? Am I in reality, or inside a game? What is the order of these three worlds? Are they separate, or connected? My name is Xu Yao. My mission is to reclaim the cycle of reincarnation that rightfully belongs to the Underworld.
