Peter Brown wanted to increase his Star Rank, and right now, the most important thing for him might still be elixirs.
Very quickly, Peter had a Pill Furnace in his hands.
Peter himself was a Master-level figure in alchemy—yet after arriving in the Divine Realm, he discovered that his refining methods still had certain differences. Besides, he hadn't yet grasped the refining techniques of this place, so his approach was to rely on purchases.
In the first two to three thousand Star Ranks, obtaining elixirs wasn't too difficult or expensive, but once he reached the 2,000-Star-Rank level, the required quantity of elixirs increased significantly, and the grade of elixirs needed skyrocketed. At this point, buying elixirs wasn't a practical solution anymore—he wouldn't be able to afford enough.
Looking at the Divine Medicine Star Planet within his Elixir Sea, Peter realized he needed to make breakthroughs in this area.
