The Cyborg System - Chapter 7: Dark Tunnel

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.
