Although the current concentration of Spiritual Qi is still somewhat short of the Fourth Rank Middle Grade, it is already quite good.
Moreover, with the presence of the Spirit Worm, upgrading the Spirit Vein of Blood Bone Island to Fourth Rank Middle Grade is just a matter of time.
"Perhaps I can find a way to help the Spirit Worm break through the fourth rank..."
"If the Spirit Worm can break through to the fourth rank, its ability to refine the Spirit Vein will be greatly enhanced, not only significantly shortening the time it takes for Blood Bone Island's Spirit Vein to transform."
"There is even a chance to reach a Fourth Rank Upper Grade Spirit Vein, or even a Fifth Rank Spirit Vein."
At this thought, Xu Ping couldn't help but feel a surge of excitement.
Even achieving a Fourth Rank Upper Grade Spirit Vein would be enough for him to become a Late-stage Nascent Soul Cultivator.
