[Behind the scenes] + [No heroine] + [Apocalypse] + [Cthulhu] + [Superpower] The peaceful world is flooded with unknown terrors, and the shadow named Cthulhu gradually engulfs the world. As the power of the old rulers completely polluted and eroded, the ghouls of the lower independent race, the Tindalos hounds of the upper independent race, the deep divers of the lower servant race, and the black goat cubs of the upper servant race came from other worlds. Their eyes were all set on the dominant race in this world - humans. Intended to bring the entire world under the power of the Old Ones. And just when the breath of the old masters was about to envelope the world and all mankind, an otaku named Fang Xiang accidentally obtained an old savior game and extracted characters with extraordinary powers in the game. The arcanist nicknamed Son of Thunder, the berserker codenamed Hand of Dawn, and the radiant priest known as the fanatical believer. Develop extraordinary power and repel the power of the past, thereby saving the world that is being targeted by the old days. Eventually, with the help of the power of the past, it developed into a top force spanning all the worlds.
