Gu Shanhai flipped through and thought about it, he was right; if he had truly focused only on body refinement, he would have trained himself to death long ago.
This was essentially still Qi Refinement, but it achieved the effects of body refinement through an extremely painful process, diminishing the importance of mana in the early stages and focusing instead on the physique.
Therefore, in the Lower Three Realms, his mana would not be as strong as his contemporaries.
Only when he reached the Spirit Origin Stage and could accommodate a Spirit Vein would he be able to make up for this defect. Correspondingly, while possessing powerful mana, he would also have a stronger physical body than others at the same realm—an advantage that would continue indefinitely. However, during this process, the practice of refining the body with energy could not be stopped. He had to endure a more painful training process and consume more resources than others.
