The battle where Riku unleashed a charge of pigs that were set on fire reminded me of Tian Dan’s Fire Bull Columns during the Warring States period, while her swift actions in suppressing an attempted plot of fire and confusion to open the gates reminded me of Zhang Liao of the Three Kingdoms.
Update: This is one of those stories that can be understood using Google Translate, as the dialogue and actions are easily digested (at least, for me). I have read ahead to ch300 in the raws and my initial assessment about the story's perverse direction seems to be in error: the MC attracts the attention of other beautiful women but he remains loyal to his number 1 girl. There have been lapses but they are written "as unavoidable" and he keeps repeating to them "I have a girlfriend". The story seem to move along at a decent pace, a lot of foreshadowing about the mysterious martial/cultivation world as well as his forays into the criminal underworld. For those worried about a perverted MC, rest assured that he remains level headed as far as I have read.
