"Ah! I know! It's called the Essence Crystal Stone!" Qiao Zixian seemed to recall something, her eyes shining as she looked at the Essence Crystal Stone in Mu Qianyue's hand and said, "I heard someone mention before that in the Ancient Wilderness, there's something called the Essence Crystal Stone, and the Spiritual Energy contained within can be used directly for cultivation. Even in the Ancient Wilderness, these Essence Crystal Stones are extremely rare, much more precious than any Jade Crystal Stone or Elemental Crystal Stone!"
"There's another one over there!" Qiao Zixian said excitedly. She quickly got up, walked to the side, and picked up a fist-sized Essence Crystal Stone from the crevice in a nearby black rock.
Afterwards, Mu Qianyue and Qiao Zixian continued to discover several Essence Crystal Stones, a total of fifty-six pieces!
"Haha, we've struck it rich this time! These Crystal Stones are enough for us to level up!" Qiao Zixian said excitedly.
