Review Detail of Veriok in Abe the Wizard

Medieval-esque setting with bamboo growing everywhere. Almost burning freaking stone castle with fireball. Knights empowered by mystical qi. Killing for a toilet design. Royality everywhere. I can forgive mc being a cheat. I can forgive mc being an muscle-brained idiot or vilain without soul. But i can't forgive no logic being put into world building and zero repercussions for mc moronic actions. Zero research being put into work before sitting and writing silly things.
