😋I recommend to you the novel 'Top-grade Young Master Cultivator'. This novel fits your requirements. The main character was a self-cultivator playboy who had been chased out of his family and became his fiancée's male servant. Why was his cousin, school belle, female thief, chivalrous man, and all kinds of beautiful women looking for him? No matter how strong he was, he couldn't deal with it. He still had to cultivate! Especially the plot you mentioned. His cousin's father did die, and in his will, it was stipulated that he had to marry his cousin to inherit the family business, and his cousin also asked them to get married. The plot of the story is very fascinating. I hope you like my recommendation, Mwah ~😗
