After the protagonist Lin Fan traveled to Douluo Continent, his martial soul was not a traditional beast martial soul or weapon martial soul, but a supreme skill from "Fighting the Heavens" - **"Burning Technique"**. This martial soul has no fixed physical form. It exists in an invisible and intangible "devouring" and "evolving" characteristic, and is the foundation of all Lin Fan's power. It perfectly integrates the soul power system of Douluo Continent with the fighting spirit and strange fire system of Fighting the Heavens, and manifests in the form of a martial soul.
