The camera opens in the shepherd's flock outside the vast congestion, and the figure of the hero Xiao Feng stands between the wind and snow, and the grievances and hatreds of the past circulate in his deep eyes. On the eve of the life-and-death duel on the bluestone bridge, Zhu Danchen gambled with his life and staged a tragic stand-in plan in the dark night, and all of this was silently witnessed by Ah Zi who was hiding in the corner.
Revealed by Master Zhiguang, Xiao Feng, a hero formerly known as Qiao Feng, uncovers the secret of his family of Khitan nobles. However, in the pursuit of the identity of the "leading brother", the clue came to an abrupt end with the death of Master Zhiguang. Conspiring with Zhu Danchen, they are determined to find the last person to know, Kang Min, and after revealing the truth, they stay away from the disputes in the Central Plains and return to seclusion to herd horses and sheep.
Zhu Danchen wittily incarnated as Bai Shijing and approached the scheming Kang Min. Although she was alert, under Zhu's skillful interrogation, a shocking secret was finally revealed: the eldest brother in charge turned out to be Duan Zhengchun, the king of Dali Zhennan. In order to help Xiao Feng take revenge, Zhu Danchen did not hesitate to steal the Shaolin secret book "Yijin Jing" and give it to him.
At this time, Zhu Danchen hurriedly came to inform Xiao Feng that there was an enemy chasing and killing, and asked him to go to Xiaojing Lake to send a message to the Savior. There, Xiao Feng witnessed the scene of Ah Zi being accidentally pushed into the lake by Duan Zhengchun, but he never expected that this was Ah Zi's plan to lure out his mother Ruan Xingzhu. After Ruan Xingzhu found the tattoo and gold medal on Ah Zi's body, he was shocked to recognize her as her long-lost daughter, and Ah Zhu also touched the heartstrings because she was also the daughter of Duan Zhengchun and Ruan Xingzhu.
When Xiao Feng learned that Duan Zhengchun was the mysterious leading brother, he was furious and wanted to slash the enemy. Unexpectedly, the four villains suddenly appeared, and Chu Wanli bravely resisted Duan Yanqing and died unfortunately. Duan Zhengchun was grief-stricken, and fought against Yanqing but gradually showed defeat, Xiao Feng stepped forward and repelled the enemy together.
After the battle subsided, facing Duan Zhengchun, Xiao Feng questioned him about his past. Duan Zhengchun mistakenly thought that Xiao Feng blamed him for the chaos of his private life and was willing to bear all the charges. The two agreed to settle grievances on the bluestone bridge of the third watch. Zhu Danchen knew the misunderstanding, and in order to save his father's life, he decided to go to the appointment instead of Duan Zhengchun, and stopped Xiao Feng at the cost of his life at a critical moment. All this was seen by Ah Zi, who was hiding in the shadows.
When Xiao Feng buried his best friend Zhu Danchen, he painfully realized that he had killed an innocent person by mistake, and his heart was like a knife. At the same time, Qin Hongmian and his daughter found Ruan Xingzhu to question the old hatred, but they accidentally involved Kang Min, the hidden rival in love and the real murderer of Ma Dayuan. The crowd tracked down to Kang Min's mansion and witnessed her betrayal and torture of Duan Zhengchun. It turned out that behind the man in black was Bai Shijing, who had an affair with Kang Min, and he was assassinated when he tried to kill Duan Zhengchun. Xiao Feng took advantage of the chaos to rescue Duan Zhengchun, while Kang Min died of extreme fear after getting a mirror.
Facing the cunning and willful Ah Zi, Xiao Feng was both angry and guilty. In a battle around the "Shenmu Wang Ding", Ah Zi showed a strong survival instinct and selfish character, and even did not hesitate to collude with the Star Sect. After a series of conflicts and twists and turns, although Xiao Feng was angry at her ruthless methods, out of his commitment to Ah Zhu and Ah Zi's life hanging by a thread, he chose to take her around to seek medical treatment, and even did not hesitate to step into the depths of Changbai Mountain to find life-saving ginseng.
Xiao Feng not only exhausted his financial resources, but also showed his tenacity and benevolence in his dealings with Wanyan Aguta, the leader of the Jurchen tribe. His emotional entanglement with Ah Zi is complex and contradictory, not only the harsh reprimand for her, but also the remorse and all-out treatment after accidentally injuring Ah Zi.
