This novel just weaved in so many of my favorite genres and passions it’s kinda hard not to love it. First it is a semi historical set in like an alternate early to mid 1400s but the twist it has is that the main character has modern mechanical engineering knowledge. The novel interweaved what seems to be crusader kings, Europa universalis 4, and the isekai genre. If you decide to pick up this novel, you will see court intrigue, warfare, conquest, nation building, romance (with some “plot”), and a whole lotta guns. What I believe truly sets this novel apart however is that the main character is by no means perfect and actually adapts to the environment he finds himself in. First, he is in the gray for morality, second in introducing modern technology you won’t see machine guns or tanks versus knights, and third, he can become cocky and gets burned for it. As for adapting to the environment, our protagonist is an atheist, yet recognizes the importance of religion, he does not try to implement a modern justice system, but an extremely harsh one, as well as other things you can find out along the way. As for the other characters, they are all interesting and have at least one unique point about them and their interactions with the story.TL;DR a great novel that brings to life history in a traditional and fun way
