After the Flame Embryo entered his body, Tang Feng did not dare to be careless, for it had been nurtured for tens of thousands of years and contained a tremendous amount of energy.
Tang Feng had been looking for an opportunity to break through the Foundation Establishment Realm, and now this opportunity was exceptionally good, perfectly suitable to use the Fire Seed within the Flame Embryo to cleanse his meridians.
He had always refined his meridians with the best elixirs he had, bringing them to their peak state, but Tang Feng wouldn't stop there. If there was a chance for improvement, it shouldn't be wasted.
The terror of the Fetal Fire goes without saying, and Tang Feng gritted his teeth, enduring indescribable pain as his bones and meridians were tempered like forging iron, continuously being refined.
It repeated over and over again.
Tang Feng could feel his meridians becoming inflamed, as red-hot as molten iron.
