Rare Body Refining Techniques of the Foundation Establishment Stage in Liyang City are quite plentiful here in the Four Seas Immortal Palace.
However, compared to hundreds or thousands of Qi Cultivation Martial Methods, Body Refining Techniques are still niche.
After making a selection, Xu Mu decided on a Body Refining Technique called "Heavenly Extreme Purple Thunder Body".
The reasons for choosing this were two-fold. First, it was the most expensive among the Body Refining Techniques that were on offer. Allegedly, if one cultivated it to the Transcendent level, they could control Heavenly Punishment Purple Thunder and slay Golden Pill practitioners beyond their realm.
The second reason was that this technique came with one additional Divine Skill of Thunder Escape named Thunder Wing.
