The Tang Dynasty's Simpleton Son-in-Law: My Sister Is the Crown Princess, Season 3

About the story

The crown princess is gravely injured in a plot and hangs between life and death. Wielding twin hammers, Su Hao fights his way through Chang'an, forcing the Prince of Wei to flee into the imperial palace and the aristocratic clans to surrender land and pay compensation. But before the turmoil subsides, Empress Zhangsun suddenly becomes critically ill, and Li Shimin grabs Su Hao's hand, begging him to save her. Can a “simpleton” who began by tending horses and supposedly knows only how to make refined salt and paper really save the empress of Great Tang? And what kind of future will this “simpleton” bring to the dynasty?
