Review Detail of DBBlackfyre in A Time Traveller's Guide to Feudal Japan

The story starts really well and the author makes a really good setting and develops the characters really well at the start. However when the MCs brother, lord and many of his friends end up dying is when it starts going downhill. The MCs character becomes inconsistent, from a pacifistic scientist to a bloodthirsty despot, the rest of the characters just lose most of what makes them good in the first place and become just placeholders, you can see this that the author barely mentions most of the survivors and close friends of the MC for more than a sentence or two. The battles can be interesting enough however, if every victory is a pyrrhic victory after two battles you dont have an army. Now the MC's army doesnt have many casualties later in the series however if you just slaughter your way through a province you plan to rule you end up ruling nobody. In other words the enemies are made to be just created from thin air, coupled with the fact that the start of the story showed us how hard it is from a village to recover from a failed campaign and how the MC knows this, his ruthlessness against what will be his own people are baffling to say the least. Another drop in quality and continuity is the whole monk arc. The author starts the series with a sci fi element, the AI teleports our MC through time to the sengoku era. Then it mostly follows a realistic historical setting, and then all of a sudden we get super powered monks, hidden arts power levels just like any other cultivation novel. And after that ark our MC is basically a god amongst men, he has profound understanding of everything and peerless martial prowess, and of course he trains his men in the same way so now he has an army of ridiculously powerful soldiers, which he recruits in a really filler way ( oh i was coming back from the mountain and they happened to be wandering around teehee). Over time the man from the future that wants a quiet peaceful life just ceases to exist and in his place is a bloodthirsty despot who does not care if he slaughters ten or a million people. Now all this could be how the author planned to have his character end up but personally i dislike the development. Another point i want to make is that in the end the premise of being from the future is just used to give his troops better rifles and cannons and has no other influence on the story. At the start of the novel i was hooked and would have given it full stars, however reading 200+ chapters i cant help but feel disappointment for all the lost potential of this rather unique novel.
