Four Styles School's Sword Art chosen by Su Xing .
This was saved by the Fifth Generation Headmaster, but cultivating it was abnormally challenging. One hundred and eight swords required Heavenly Qian Magnetite and Kun Spinning Sand to forge; it was simply unable to be practiced. The reason why Su Xing chose this was only because he felt this One Hundred and Eight was mutually a good fit with the Heavenly Spirit Earthly Fiend Purple Star Five Elements Sword. Upon it was recorded a few Sword Arrays that could not be said for sure to intercommunicate usage.[1]
