I am a Primitive Man - Chapter 76: Had never met such a shameless, despicable, and cunning tribe

A top-secret experimental explosion transports Xiao Ming to a parallel world resembling ancient times.In this hostile land, he is the most unfavored prince, given the most barren fiefdom.Fortunately, however, a mysterious item from the experiment—the Technology Crystal—comes with him, granting him the ability to upgrade a technology tree.Thus, he begins a leisurely life in his fief, farming and developing industry.In the face of his unfriendly brothers and sisters, he has always followed the motto- friends come and get wine, jackals come and get shotguns.

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.
