At Shushan Sect, Li Shiming, aside from his once-daily alchemy practice compared to the previous five times a day, needed only around three to four two-hour periods to craft Third-grade Spirit Pills, and consequently, he had some extra time.
He then began to look into the artifact refining legacy he had acquired before. Of course, the artifact refining legacies in his possession were of very low grade, but they were still sufficient for an introduction to the craft.
In fact, using the Red Sun Spirit Fire, which was nearly at the Golden Core standard, to learn artifact refining was a tremendous waste.
Especially since he was still using First-grade Materials for practice, resulting in the production of Magic Artifacts.
Crafting Magic Artifacts was not difficult, but he soon recognized the limitations of the artifact refining legacy he had.
