Qin Yu, a transmigration survivor in a parallel 2009, possesses a notorious reputation as the entertainment industry's ultimate 'scumbag.' Accused of seducing top starlets like Yang Mi and Reba, he finds himself blacklisted by major agencies and abandoned by his manager. However, his scandalous behavior masks a secret: a 'Female Star Assistant System' that rewards him with skills and treasures for every intimate interaction.

With a fortune amassed from his exploits and a cache of future classic scripts, Qin Yu decides to pivot from actor to director. He recruits Bai Lu, a loyal young assistant who quits her job to follow him, and targets Ni Ni, a skeptical beauty, to star in his debut film. As he navigates industry conspiracies and his own infamous persona, Qin Yu aims to prove that the man who broke the most hearts can also direct the most soul-stirring romances.

Can the 'Cannon King' wash away his sins with cinematic masterpieces, or will his past destroy his future before the cameras even roll?
