Then came the Blood Refining Array.
This was why Brand wanted to avoid others; the Blood Refinement Technique actually comes from Madara's alchemical skills and is one of the forbidden techniques strictly prohibited within the Flame Temple. This is mainly because Blood Refinement harms the caster themselves, which contradicts the basic doctrines of the Flame Temple.
But it must be said that Blood Refinement is a very practical skill because it allows alchemists to complete some simple material synthesis without alchemical apparatus under any circumstances.
To be honest, although the Flame Temple strictly prohibited it back then, there were still a lot of players in Erune and Kruz using this technique. Players only cared about effectiveness, and at most, they would lose one level if discovered.
Moreover, generally, they wouldn't be discovered, would they?
