Inside the Great Yecheng City, many cultivators couldn't use their True Qi, so they practiced body refinement techniques. Thus, many people cultivated both aspects. However, body refinement was not an easy task. Even if they had the techniques, many couldn't afford the required medicinal baths.
In the Cultivation World, body refinement was divided into twelve levels, which were entirely different from the typical cultivation technique levels system.
Due to Nathaniel Russell's family wealth, he could afford various medicinal baths for body refinement. He became skilled in body refinement and reached the Body Refining Level 4.
At this level, he was capable of destroying a Golden Core practitioner's Elixir Sea. Thus, even Golden Core practitioners wouldn't dare to confront him directly, as they couldn't use their True Qi at this time.
