The Noble Young Master of the Song Dynasty

[Highly recommended, a satisfying historical novel] After transmigrating into the Northern Song, he becomes the youngest son of Lady She. Since his older brothers all died on the battlefield, his sisters-in-law dote on him from the moment he is born, and he becomes a notorious young wastrel throughout the capital.

But his playboy ways and debauchery are merely a disguise. As a transmigrator armed with knowledge from the future, how could he fail to stir up a storm in the impoverished and weakened Northern Song?
