Either Sword God or Sword Demon was essentially a wisp of Zhong Shengming’s remnant soul. It was just that the strength of this Sword God of Bai Li was too powerful that even if it was just a remnant soul, it was seemingly as powerful as other cultivator’s intact primordial spirit.
Of course, a remnant soul was still a remnant soul. Behind its power, there were some limitation and weakness. As for a corporeal body? That was even more an excessive expectation.
However, for Wang Lu’s question, Sword Demon only gave a faint response, "For cultivators above Unity Stage, mortal body is not important. As long as I can unite with the other, the remnant soul, primordial spirit, magical power, and mortal body can be fully integrated with each other."
