Review Detail of Vrikzar in Tyranny of Steel

I like Historical KBs and this novel have taken setting in an interesting period of mediaeval Germany in an AU. Everything is good character building, relationships, world setting except the pacing. It has very fast pace of tech upgrade which is barely justifiable till ch90, but the social transformation is purely unrealistic you just do not survive after revoking almost every noble rights of your vassals, excommunicating by pope, being incharge of advanced weapon manufacturing which everyone knows, as a 'baron' nor do people get educated enough for a form of representative democracy with few months. Society does not work that way but hey it's just a light novel.
