The imperial court appoints Qingyuntang's number one killer "Yun Xiao" to assassinate Empress Dowager Jiang and is chased by the imperial guards. When he is desperate, he meets "Jiang Zhiyuan", the leader of the Baigui Alliance, a notorious individual killer organization in the world. He learns the true purpose of Baiguitang and the shocking conspiracy within the court. But he did not choose to go with Baiguitang, so Jiang Zhiyuan fought fiercely with Yun Xiao, but Yun Xiao had to escape because the Imperial Guards were approaching. On the way to escape, he was accidentally hit by an arrow and fell off a cliff. His life and death are unknown.
At the same time, "Ning Shu", the only son of the wealthy businessman "Ning Jiucheng" in the capital, has the dream of a peerless hero in his heart. While "acting chivalrously and doing justice" with his partners, he accidentally encountered the bad luck of "Yuwen Shangwu", the son of the prime minister of the dynasty, but was involved in court disputes and turmoil in the world. From then on, he started the "road of a hero" that he had longed for.
