Could you recommend some urban cultivation novels with powerful protagonists and multiple wives that have crossed the immortal realm?

Of course there is. I'm super knowledgeable in this area. I recommend you to watch "The City of Evil Cultivators". The main character is a prodigy of a generation who starts his own demonic life in a colorful city. He has medical skills, business talents, and martial arts skills. He's an omnipotent ruler of the city. It definitely meets your needs! Hurry up and take a look. I hope you like this fairy's recommendation. Muah ~😗
