Xiaoyu, Autumn Cicada, and the Darkpearl Clan

"The Darkpearl Clan? They're one of the few bane existences of the Demon-sealing Fiendish Blade!" Old Black was deeply worried and dejectedly said this. "The God Race warriors are in a bad state, especially Xia Fei!"

The Darkpearl of Demon Race took its name from the 'Heaven Dark Earth Pearl'. Just like how the Skywing Clan was one of the few families in the Law Realm that had mastered the Law of Speed, this most extreme and difficult law, the Darkpearl Clan's elites were skilled in the two powerful Laws of Mist Concealment and Flash Blitz.

As its name implied, Mist Concealment was immersing the world in a thick fog that the Darkpearl warriors could hide in. Their bodies could turn into mist and they could use Law of Speed to quickly strike their foes.
