Review Detail of Zen_Fay in Being Blind For Five Years, All My Disciples Became Forbidden Curse Mages

What really disappointed me is that they never explained execution of magic and how they worked. All we know is that English is magic and stronger the caster stronger spell. We have no idea of the incantation or if every sentence is magic. It's was a easy and interesting mechanism to explore. The fls makes fireflies that burn on impact, acid rain, illusions, etc and how they work or the incantation are unknown. I mean even some of the trashiest novel have better explained magic than this novel.
