Mixed Element Spirit wasn't a sword principle that focused on its form.
It focused on the mood, or in other words, sword intention.
The sword intention could be combined with the doctrine that a person comprehended perfectly.
Jian Wushuang comprehended Reincarnation Doctrine and his sword intention could become a reincarnation cycle. For instance, Jian Wushuang turned into a space blackhole that revolved like reincarnation and swallowed everything.
Although he continuously performed over a dozen strokes and they looked like they were different, in actual fact, he was performing the same sword principle, Mixed Element Spirit. It was merely because there were many patterns and forms.
"Among the four moves in Sword Principle Xuan Luo, Mixed Element Spirit was the most exquisite one. Because of Mixed Element Spirit, people found the sword principle perfect and almost flawless," Jian Wushuang muttered.
