Eight years ago, Li Changjun married into the Chen family. In name, he was a live-in son-in-law; in reality, he was a hostage! Fed scraps and made to sleep in a cowshed! Eight years later, Li Changjun, deputy commander of the frontier forces, returns in triumph! When the Chen family orders him to kneel before the ancestral tablets, he merely bows slightly, and the shrine cracks apart! The Li family considers him a disgrace, but he smiles calmly and establishes a new Li household! A living legend returns to the city! The dragon takes to the sea, and the son-in-law becomes a god of war!
