Resolved mc is a dungeon, novel at royalroad.

hello. maybe mc is former engineer, not sure. makes his dungeon at cave, including double door at surface entrance. for no reason starts singing and every npc goes 'omg, too domineering!!1'
failed to find it myself, thanks to all those similar dungeon core stories at rr.

 

Try to find it here! I'll look out for it.

I think it's either Dungeon Heart or this.

 

Yeah, if the MC used to be a dwarf then it's dungeon heart

 

Blue Core ?

 

thanks people! it is dungeon heart. strange how i forgot it was all dwarfy.
edit in: by the way, really recomended. it sure puts 'dung' in dungeon.

 

Is it that bad?

 

sorry, just joking.
