I'm a Sword Immortal in a World of Magic

[Fantasy + System + Transmigration + Academy setting] Ye Qingfeng transmigrates to a world of magic, only to discover that he can't awaken a spellbook! No need to panic. I've got a golden finger: the Sword Immortal System. And so, among a crowd of people carrying magic staves, one person appears with a sash around his waist and a sword on his back. “Praise the will of nature, flame…” Before the passerby has even finished chanting, a gleaming sword is already at his throat. … What kind of stir will the Divine Sword Art of Thunder, the Green Lotus Sword Song, the Nine Swords of Dugu, and the Zhuxian Sword Formation cause when they appear in another world and the realm of magic… (The story stays clean from the middle onward, so read with confidence.)
