Li Mo had barely returned to the inn before he seized the time to prepare for refining the Desert Diagram.
The Fourth and Fifth Refinements mainly tested a cultivator's control over spiritual power. After all, fully fusing several types of spiritual herbs was enough to make one's scalp tingle just thinking about it.
It was rare to see Low-grade Magic Tools above the Third Refinement in the Black Market. Even if a Magic Tool Blank had the potential for five refinements, continuing the refinement was simply not worth the cost.
Mid-grade Magic Tool Blanks had a greater capacity for spiritual herbs, and even the difficulty of the Tenth Refinement was actually inferior to the Fifth Refinement of a Low-grade Magic Tool.
Li Mo felt that he had a fair degree of confidence, so he began grinding the spiritual herbs for the Fourth and Fifth Refinements.
The spiritual herb selected for the Fourth Refinement was Grinding Jade. Its exterior resembled a rough, coarse jade stone, and it could allow the Desert Diagram to aid in healing injuries.
The spiritual herb for the Fifth Refinement was Gravel Sand, used purely to enhance the Desert Diagram's defenses.
