it's made by him from another universe
holy shit- so the dungeon was another universe??
It's not another universe, guys. The world was reset twice before. On the second or first run through, the sword was made and lost in the dungeon. Time in the dungeon doesn't flow the same way it does outside,. So Yeseong doesn't remember making it as the world ended already.
ohhhh! thank you kind stranger for the info! (⌒▽⌒)
no probs! i read the novel before I read the manga so I know the story
I need someone to spoil me, how tf is something that hadn't made, was already made, it even got his engraving and everything, the sword was even calling him father Σ(っ°Д °;)っ
