Varreth was extremely baffled about how Simon was able to advance his demon heart in less than twenty four hours, and two answers came to his mind when he pondered on this oddity.
The first is that Simon had killed so many candidates or beasts, and devoured their demon hearts to advance his.
However, Varreth immediately knew that this conclusion was wrong because of so many things.
The first was that Simon was a Minor Lesser Demon the last time he saw him in the barrier, and majority of the candidates were Fiends.
For Simon to have advanced from a Minor Lesser Demon to a Superior Lesser Demon, Simon would have needed to consume and refine the hearts of between twenty to thirty Minor Fiends.
Even if Simon had the ability to battle twenty to thirty Fiends- a feat which was abnormal- there was no way he could refine the hearts of so many Fiends in less than twenty four hours.
