Swordman of Gods and Ghosts

A player of a Dungeon & Fighter Ghost Blade class character accidentally crosses into another world carrying the Ghost Blade’s skills.

Ghost Blades possess an arm cursed by ghosts and gods, called the Ghost Hand.

Swordsmanship branch: Furious Dragon Heaven-Cleaving Slash, Phantom Sword Dance, Ultimate Ghost Sword: Storm Style. Through training in weapons, I will no longer submit to the curse of the ghosts and gods. Is this not the pinnacle of swordsmanship?

Wave branch: Evil Light Wave Array, Immovable King of Light Array, Dark Sky Wave Eye. When light disappears, I will use wave power to illuminate the path ahead!

Blood Qi branch: Soul Devouring Demon-Sealing Slash, Collapsing Mountain and Splitting Earth Slash, Demon Prison Blood Massacre. As long as I can obtain power, I will not hesitate to sell my soul to the ghosts and gods!

Ghost and god branch: Ghost Shadow Flash, Nether Flame Carlo, Seventh Ghost God: Evil God Bu Lashius. Whether one can sever the chains of fate depends entirely on one’s own will!

What kind of changes will this world undergo when these powerful Ghost Blade-exclusive skills appear in a different world?
