Hill understood after hearing Fran's words.
This archmage, who insisted on descending to explore the demon's den, definitely had some connection with demons.
He was probably worried about his faction leaving traces behind there, which was why he had to go down and check.
Moreover, a normal archmage, even if they spent a longer time below, wouldn't just turn into a demon so directly.
If it were that easy, why would demons bother attacking human cities? Just besiege them for two days and they would transform into the same kind?
It was indeed foolish, not even knowing one's own limit of tolerance to the demon's power.
Even though the Mage Association seemed chaotically terrible, with elves and dwarves involved, not to mention those who cooperated with demons.
But neither William nor Fran paid much attention to it.
Hill thought about it and then understood.
Because those at the very top, the legendary lawkeepers, had no issues.
