Yes, I recommend the novel "The Universe's Hack System." The male protagonist is a hacker who developed a cheat. After designing the cheat, he suddenly had an accident and transmigrated into the body of a genius youth from his family. He had the system in his hands, so he could act cool like the wind, step on the silkpants, and reverse the situation to reach the peak that no one knew about. This novel belonged to the category of Xianxia-fantasy immortal cultivation novels. Although it did not completely fit the identity of a profligate young master, the male protagonist did appear as a profligate young master. Moreover, he was very talented and worth reading. I hope you like my recommendation. Muah ~
