It's fine. I hope someone writes a story with a similar concept, but in a fantasy world filled with magical elements. This is basically just a historical novel. The MC ended up in a certain period, he's a history buff, he knows what's going to happen next, and talks about it with the king and his subordinates. For example, traveling back to ancient Rome and talking with Caesar, fixing his mistakes. Obviously there's no Caesar nor Rome here, but that's essentially what the novel is. It's a cool premise but it doesn't suit my personal preference as its just normal humans with our normal politics. There's no real plot.
