The Nine Secrets are the Inheritance Secret Technique left in the Ghostly Face Mask by the Cruel Demon Emperor.
The Ghostly Face Mask has a total of eighteen seals. Every time Su Han breaks through a Great Realm, he can unlock one of them, obtaining a secret technique, each being the ultimate in its respective domain.
So far, Su Han has obtained seven secret techniques, each providing him with great assistance.
Unfortunately, the Nine Secrets cannot exert their ultimate power upon acquisition. So far, Su Han has only cultivated the Character Technique of Motion to minor accomplishment, capable of exploding with double the speed of sound, while the other six secret techniques are just barely past the threshold.
If each secret technique is cultivated to the extreme, they are comparable to Divine Arts, possessing boundless power.
