"Stygian Devil Mask?"

This was an advanced dao treasure-level mask. Wu Yu had heard of it.

In his field of vision, the three of them had appeared suddenly and all of them were wearing pitch black masks that sealed their appearances. They even obstructed Wu Yu from sensing the three's abilities.

Hence, he did not know what cultivation levels these three were at. 

He had no way of telling.

"I heard of an organization called Stygian Devils in the Yan Huang Ancient Region. It has power and influence in various major martial cultivator empires and belongs to no one country. It specializes in assassination and is akin to an assassin's organization in the mortal community, just that the members are all martial cultivators…."

Wu Yu did not expect to one day be targeted by the Stygian Devils.

Wu Yu smiled while looking at them and said, "Let me guess who hired you guys to attack me. Who else knows that I'm out on the Hidden Immortal and hates me? Perhaps one of the princes or princesses?"

Actually, Wu Yu...
