457 is not a Blessed Monk

Can a Blessed Monk devour souls like a Sin Demon? This is the first time I've heard of it.

The characters I've encountered who engage in soul refining seem quite numerous. Before, they were freaks, but now it's Blessed Monks and Sin Demons... However, considering that Sin Demons are essentially the archetype of freaks, one should say that the power of soul refining in freaks is a mere imitation, while the Sin Demons are the original version.

Since Mazao is also a Blessed Monk, she must possess the power of soul refining as well, yet I've never heard her mention it, let alone witnessed her display it.

Moreover, when she first crossed over, her soul was heavily injured, precisely when she most urgently needed to devour souls for self-repair. Why didn't she exhibit such abilities then? Although her character is kind-hearted, she does have a side that disregards modern laws, and in an emergency, it shouldn't be too difficult to find some deserving people to kill...
