When MC was reliving a picture of a goddess, he died. Only meet the goddess, but instead of torturing him to eternity, she gives him wishes. And make him reincarnated in the Overlord world.As the name suggested, this is multiverse Fan fiction, that means MC will travel through different world like Marvel, DC, High School DXD, My vampire Diaries (may be) , Demon Slayer, etc.first world: Overlord (Chapter: 1—60)second World: Highschool DXD (Chapter: 60—215)Third World: Demon Slayer(Chapter: 216—)Fourth World: New World (Overlord)There will be a harem, no NTR or stuff.Some of you might dislike the Yggdrisil arc as it is a bit of AU and MC talk a lot. But it is only in this arc on world travel that I will tone down his unnecessary internal monologue.I am not a professional writer, and I have no deep experience in writing, so please ignore my grammar mistakes and such. I also took some inspiration from other fan fiction.It would be a great help if you could donate your power stone to me.

“I, an Immortal Cultivator in this world of superheroes, alone understand the Dao.”Elius Northrim had a peaceful life—until he blacked out and awakened with tragic memories of his past life.Along with those memories was a realization that in his eighteen years, he was living in a brutal superhero universe, and his ruthless alien father—whom he had never met and a SUPERMAN equivalent of this world—was coming for his life because one of his brothers, the main character of the comic awakened his Solarion bloodline.Surviving while being mistaken for an awakened Solarion offspring of his father too, Elius must keep the truth hidden—he’s not one of them, but an immortal cultivator.If his father discovers the deception, both he and his mother will die.But the worst part is that he has become his father's favorite among the two. To avoid being constantly under his father's watch, Elius enrolls in a superhero academy, blending in while secretly growing stronger.However, with rival students, watchful instructors, and his father’s looming presence, one mistake could mean death.Now, he must master his powers, play his role, and survive—before his secret is exposed as a lone immortal cultivator in this world of Superheroes.
