Douluo: Martial Soul Body, Possessing a Primordial Spirit?

Xia Xuan, a fan of Douluo Continent, arrived in the world of Douluo with his memories intact. Fortunately, he lived in the same era as the future Tang God King, meaning the divine lineage hadn't been severed. He awakened his martial soul form independently, and it was a complete form. A sudden realization dawned on Xia Xuan: indeed, the soul is part of the physical body. (He doesn't follow the third brother, developing independently.)
