[Lu Ling Jue+1431]!
[Proficiency in Lu Ling Jue; 1328/1600]!
The reason why Xu Mu didn't continue to accumulate Luck Value to rush the Lu Ling Jue to the Proficiency level all at once was first out of fear of missing the Flying Boat, and second because it was unnecessary.
A normal cultivator, once they train the Lu Ling Jue to the Proficient level, would already possess the ability to refine spirits.
With Xu Mu's current level of Lu Ling Jue approaching Proficiency, there would basically be no accidents.
Unless his fundamentals were too weak!
Clearly, Xu Mu's fundamentals were not weak at all. Few within the same realm could compare with him. Compared to the typical Qi Cultivation ninth level, he was only stronger, not weaker.
The most critical aspect of refining spirits is the spirit!
Xu Mu's spirit, reinforced by the double-enhancement of the Fire-Controlling Skill and Thunderbolt Sword Skill, was far stronger than those in the early stages of Foundation Establishment.
