There were two male protagonists who met these conditions, namely,"The King's Little Security Guard" and "The Dragon's Son-in-law". The male lead of "The King of the Little Security Guards" was a university security guard, who was also a gangster killer. There was also a Bugatti Veyron plot in the novel. The male lead of "The Departed Son-in-law Veyron" was a god of war. He married into the wife's family and became the wife's son. There was also a Bugatti Veyron plot in the novel. Both novels were urban novels. I hope you like this fairy's recommendation. Muah ~😗
