Li Cai, a modern social animal, died suddenly after working overtime and was reborn as the ninth prince of the Great Xia Dynasty in a different world. In his previous life, due to his mother's humble background and cowardly character, he was framed by his most trusted "good brother", the fifth prince Li Wen, during the cruel court strife. He was charged with treason and collaboration with the enemy. In the end, he was "accidentally" killed by bandits during his exile, and his body was left intact. And his fiancée Su Qingxue, who was born into a general, was also taken away from her by the fifth prince, and she died in depression. Reborn at the age of sixteen, at a critical point before the tragedy happened, Li Cai opened his eyes with all the painful memories of his previous life and the soul of a modern man.
