The novel is extremely enjoyable. I love how the MC only comes out with the ideas and asks the experts in their fields to try and implement them or researching ways to produce them instead of him suddenly turning an expert in every field and teaching blacksmiths or crafters of new inventions from modern time that he mostly had a passing knowledge of. Personality wise the MC is very likable so far as well. He”s very flirtatious and teasing think of usui from maid Sama in a harem fantasy setting. This story can be simplified with "What if Justinian I, Emperor of the Eastern Roman Empire an Elfand have a longer lifespan than a human? Can he reconquest and capture then build the Nova Romanum like in the past or not?" If you want to read earth history with some kingdom/empire-building and fantasy race in it, then I suggest you read this one. But beware sometimes later the story can really get annoying and you'll be like "wtf dude? Are you s*upid or twat?" just shrug it off then shut down your brain and that's why I only give this novel 3 stars + 1 for my favorite genre (kingdom building) oh, and idk if this makes you all get a bitter taste when reading, basically MC subordinate or his godfather got the worst story, I mean really worst even I feel bad for him when reading it.
