It is particularly annoying that the people who noticed his "talents" are not telling him about it . It's completely irresponsible and potentially lethal . Not that his "talent" had no particular explanation or that it was completely retconed 40 chapters in to force plot . It's simply annoying, because it's used as a deus ex machina for the author's intentions. Oh, something going wrong ? MC will speak some random stuff and the problem will fix itself.
