I Transmigrated as the Emperor's Legitimate Youngest Son

Every time you pick up a novel in this genre, it starts with the protagonist being a good-for-nothing and the heroine breaking off their engagement. It's the same old formula, practically rubbing readers' eyes into the ground. Seeing the same stale thing every day gets boring fast, so I'm here to offer everyone a change of pace and something fresh, giving more readers a new experience. Let's break away from the old plot formula and set out on an innovative journey toward new ideas. The times demand innovation, and old formulas will eventually be replaced by fresh ones. After transmigrating to a feudal society, the protagonist has a System but doesn't rely on it much. He's the ninth prince of the Great Xia Dynasty, and the youngest son and favorite of the Xia Emperor. As he grows older, he discovers that all the women of ancient times want to marry him. They even get jealous and fight over him, resorting to every trick in the book. The Xia Emperor's youngest daughter, the Tenth Princess, is afraid someone will snatch him away, so she treats his admirers with hostility. It leaves him at a loss whether to laugh or cry.
