However, the Blood Refinement Technique still has significant limitations.
For example, a common magic artifact can be refined with just a drop of fingertip blood, allowing it to recognize its master.
As for magic treasures, numerous drops of essence blood are required for them to recognize their owner.
Regarding spiritual treasures, Mu Jinyu wasn't entirely sure, but he estimated that "essence blood" would be necessary.
Thinking back to how Di Shitian controlled the Bi Fang Cauldron earlier, it seemed like he indeed used essence blood to nourish the Bi Fang Cauldron!
Mu Jinyu immediately gave a bitter smile.
This was why he initially chose to use the True Essence Refinement Method instead of the simpler Blood Refinement Technique!
Who knows how much essence blood it would take?
But now, there was no choice; he couldn't stay in this extremely dangerous sea of fire forever.
