Xu Xiaoshou felt the spiritual essence in his energy reserve getting restless as if they had the urge to break through shackles.
"Good stuff!"
Xu Xiaoshou's expression changed.
This was a treasure!
It was probably even better than that third or fourth-grade sovereign-level alchemy elixirs.
This was because this crystal contained non-elemental energy that could be completely absorbed by the energy reserve without 'Transformation' or the breathing technique.
"Void Crystal?"
Xu Xiaoshou took the two black hexagonal crystals and realized that this was the reward of the "Clear Intruders" mission.
"Lord Void Attendant, what is the use of this Void Crystal?"
Xu Xiaoshou felt that since this thing was called "Void Crystal" and not a cultivation crystal, it must have some connection with Abyss Island and was not solely for cultivation.
