@LOOK INTO MY EYES he went down to a lower realm while saving some baddies. The lower realm thought the crack was to a demon world or smth and not the upper realm(or was it the barren wasteland?). I guess he's here to siphon someone's fortune or secure a babe with high fortune. But I'm not really sure either anynore
@Abyssalis nahh, his main purpose is the "Sword domination". Gu let go the person who fused withvthe sword to return to his home to find a way to separate. 2nd, just wonder or interterested in sword spirit's so he's there.
