The Spoiled Heir of the Great Song

After returning to the Song Dynasty, Tang Ding has five thousand years of Chinese history at his back and a guidebook to the course of history in his hands. He might not be able to unite the whole realm in this life, but becoming a rich man shouldn't be a problem. But while Tang Ding is still daydreaming, his father holds a knife to his neck and says, “Pay me back!” His beautiful maid smiles and says, “Young Master, get up and take your medicine.”
