Tatsumi has been reincarnated as "Chikusou" and has become the Dungeon Lord of Orario! His own dungeon connects to all realms! Highschool of the Dead, Shokugeki no Soma, Gourmet Prisoner, That Time I Got Reincarnated as a Slime, Undead King, Reincarnation: Jobless, One Punch Man, Little Garden... and every battle in the dungeon converts into experience points for Tatsumi! So... Ace Wallenstein: My two minutes of deep training... and Tatsumi-sama raised his level by fifty?! Busujima Saeko: My sword is Tatsumi-sama's sword, and my body is its scabbard! Nakiri Erina: No, why are the ingredients fighting here? Storm Dragon Veldora: Dungeon? What the hell are you doing here!? Black Dragon: Master?! Save me! Albedo: Please let me fight for Tatsumi-sama! Roxy: One magic spell raised Tatsumi's level by a hundred! What the hell is a 100x entry?! Start by entering the dungeon, conquer the heavens and the worlds, and build the supreme kingdom of God!

Good news, he's transmigrated to the world of anime! Bad news, no cheat codes! Su Mu transmigrates to a crossover anime world filled with slice-of-life stories, but all he gets is a broken Sword Saint System. The system can provide him with sword techniques from various worlds, but it can't teach him them immediately; he has to learn them through his own efforts. Su Mu practices diligently and eventually becomes a sword master, but the comfortable life of modern society troubles him. No one can challenge him, and he finds amusement in beating up thugs at Soubu High School. Until one day, he obtains an Infinite Flow System, allowing him to transmigrate to different worlds and challenge powerful figures from those worlds. Su Mu has completely opened the door to a new world! *The Failed Knight*, *Black Bullet*, *The Burial of Freeland*, *Ascendance of the Fearless*, *High School DxD*, *DanMachi*, *Type-Moon*, *Honkai Impact 3rd*... From then on, Su Mu's fame spreads throughout various worlds. (Main world mixed with Aoyama Gyoukai, randomly transmigrating to Infinite Flow worlds)
