Finally someone in a martial arts story who thinks about the aftermath of a possible conflict. So you defeated an enemy group, got too many allies killed, even more crippled, and are now the lord of the land. Exactly how long do you think you will be able to keep that shit up in your weakened state with at least a hundred other enemy groups out to steal it from you?
I like the Storm Thief plot. The fact there's a rich boy after the reluctant protegé while going through the warzone makes it more complex. Props to Noh Ga Jang for keeping his head on his shoulders. Forget that rumored elixir of life or whatever it is, it's definitely not worth it. Especially not if nobody has actually managed to use it in some way. That should kinda ring some alarm bells that the rumors are only rumors, and eternal life is non-existant. Otherwise there'd already be rumors about that. Or at the very least, about someone who's practically invincible (because he's immortal).
By the way, why didn't those two at the very end notice our mc and his protegé? They're wearing bright blue, green and white outfits in a background area of black and dark brown colours ...
