As the crown prince of the Tang Dynasty, Tang Yu was willing to go to the north as a hostage for eighteen years in order to bring peace to his family and country. After his term expired, he gave up the high position promised by the empress and returned to the Tang family happily. What greeted him was the sharp sword and endless betrayal of his relatives. His younger brother Tang Tian coveted his Supreme Sword Bone, while his father, the emperor and his mother looked on with cold eyes, while his two sisters only listened to him. He was deprived of his cultivation, expelled from the royal family, and turned from the favored son of heaven to the despised one of thousands of people overnight. Little did he know that the Supreme Sword Bone that everyone cared about turned out to be an impurity in Tang Yu's body.
