Yang Chan had refined quite a few Essence Condensing and Organ Refining Pills in the Earth Fire Institute. He also had a large stock of other elixirs, which he used to speed up the process of mastering the Essence Condensing and Organ Refining Pill. After all, he wasn't aiming for mere Qualified Level elixirs, but those of the Top Quality Level.
He could trade the Qualified Level elixirs at an opportune moment. Since Top Quality Elixirs provided more Potential Points—which was what he needed most—he naturally prioritized them.
Once he improved his success rate for producing top-quality Essence Condensing and Organ Refining Pills, Yang Chan planned to start refining Rejuvenating Liver and Kidney Pills. He already had all the necessary materials for this elixir.
