It's obvious that the Great Demon Black Law is closely related to Evil Qi, while the Instant Wind Nine Curves is related to Escape Technique.
The exact function of the former is unclear, but the latter is already clear—it is certainly a technique for traveling far with the wind.
Daoist Zhenyue's method of travel, disappearing in fragmented Golden Thunder, and the Earth Escape technique of the twin sabers by Zuo Qiutian's side, are all similar spells.
However, the Escape Technique that returned Li Rui and Yuan Erliang to the plateau should be a one-time solidified function of this thing after it landed. To use it again, one must obtain the Cave Profound Yin Yang Umbrella and embed the Instant Wind Nine Curves inside it.
In any case, this enhanced Li Rui's anticipation for that legendary multi-holed equipment.
The process of obtaining this inlay is simpler than the Great Demon Black Law, at least it doesn't require slaughtering a city.
