Old man Chenchuan's granddaughter, Lu Xiaoxi, was poisoned as a child. Many years ago, Chenchuan defied the clan taboo and went to the Tai’e Sword Tomb, hoping to find a cure for his granddaughter. However, instead of emerging with the antidote, he lost his life to a mysterious and deadly Dragon Formation. With the help of medicinal herbs, Lu Xiaoxi managed to grow up, but the poison in her body also became more deadly. Mr. De, who had raised her, was always looking for a way to activate the Dragon Formation. A marshal who was determined to obtain the Tai’e Sword learned the history between the Chenchuan Clan and the Tai’e Sword Tomb after carrying out secret investigations. He forced Lu Xiaoxi and Mr. De to obtain the sword for him. In order to find the chosen one who could unlock the mysterious formation, the marshal forced Lu Xiaoxi to hold a joust to find a spouse. By a twist of fate, Chen Qi won the joust. But what he does not know is that from the moment he won, he was set on course for an exciting adventure.
