Lin Yi, of course, would not overly pursue perfection. The Infant Breaking Pill is not something he can make at this point, as it is on par with the Longevity Pill and Heaven Pill.
However, after successfully making the Spirit Level Elixir Gathering Mysterious Pill, one possibility he had previously speculated became a reality, which was the experience of his Supreme-grade Artifact Alchemy Furnace increased slightly.
This means that as long as he is making a Spirit Level Elixir, regardless of the rank, he can improve the experience of his Alchemy Furnace.
Although making a Medium-grade or higher Golden Elixir can also gain experience, and the cost of the materials is much cheaper than the Gathering Mysterious Pill, his Alchemy Skills have already improved to the Spirit Rank, and making a High-grade Golden Elixir will not give him any experience.
