Alchemy King and Alchemy Ancestor were separated by two major boundaries.
But alchemists' duels were different from martial artists. A difference of two major boundaries between martial artists, even for a monster like Ye Yuan, he could not salvage it too.
But among alchemists, outside of competing in pill refinement, Alchemy Kings still had a possibility of winning Alchemy Ancestors theoretically.
Of course, that was also just in theory.
If without heaven-defying inheritances, for an Alchemy King to want to win an Alchemy Ancestor, that was basically sheer nonsense.
The accumulations and experience of an Alchemy Ancestor were simply not what Alchemy Kings could compare to.
Especially with fire control, experience had a crucially important effect. That was the accumulation on countless times of pill refinement.
