William scoured his brain for every bit and piece of information related to the Earth Element. Every Spell he developed in the Mortal Realms, every Spell he watched others use, every Fusion Spell containing the Earth Element, and every Cultivator he'd met who had the Earth Affinity.
Practically the last four years of his life were experienced in a few minutes, everything relevant noted down and recorded in a separate part of his mind.
From merely analyzing the first three months, William learned of a Spell unique to the Desert Beetles that helped them conceal their presence in the Foam Desert. Some Outer Core Disciples of the Five Elements Sect taught him the most basic methods to increase his defense, while others had several Innate Talents that he could imitate with his current strength.
