Marrow Cleansing Elixir

This type of Marrow Cleansing Elixir was divided into many grades, ranging from first grade to seventh grade. However, the magical thing was that the prescription of this elixir was the same, and the grade of the elixir refined was completely determined by the strength of the alchemist.

In other words, two alchemists used the same medicinal herbs to refine the Marrow Cleansing Elixir under the same circumstances, but the level of the Marrow Cleansing Elixir that was refined in the end was closely related to their own strength. Due to this reason, precious Marrow Cleansing Elixirs are exceptionally rare. This elixir can quickly enhance a person's spiritual power within a short period, aiding in breakthroughs, and making it extremely rare on the market.

This time, Su Qian aimed to refine the highest grade, the seventh-grade Marrow Cleansing Elixir. However, she wasn't sure if she could succeed.
