MTL - North American Detective: I Am Proficient In All Kinds of American IAI - Chapter 3 Hidden danger

A few hundred years ago, Earth was affected by a mysterious force from the depths of the universe, triggering the revival of spiritual energy. However, things didn’t turn out as wonderful as humanity had imagined. The spiritual energy carried a strange power that caused the corpses of all living things to rise again, transforming into ghouls. And above these ghouls, even more terrifying beings existed…There were no ancient methods of cultivating immortality, nor any legendary awakenings of supernatural powers. But within the spiritual energy, there was also a presence of ghostly energy. This led to the emergence of Runes.Some people bore mountain runes, enabling them to move mountains and overturn seas, suppressing chaos. Others carried river runes, allowing them to reverse the flow of mighty rivers with a mere gesture. However, this process required a special profession to assist these rune cultivators—to constantly modify and engrave their runes, making them more refined and perfect.This profession came to be known as Rune Engraving.

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.
