After losing her memory in battle, skilled archer Fu Yixiao is taken in by a noble family and unexpectedly reunited with her former enemy, Prince Feng Suige, the man she once struck with an arrow.
During the battle in Pingling City, Jinxiu’s military commander, Fu Yi Xiao, severely injures Susha’s eldest Prince, Feng Sui Ge, who quickly flees for safety.
Feng Sui Ge tortures Fu Yi Xiao to gain information about the battle at Pingling and, in so doing, helps her remember some of her past memories. He decides to keep her alive, hoping to figure out who tried to assassinate them.
Before striking a deal to cooperate with each other, Yi Xiao and Sui Ge get even with each other. Yi Xiao lures the assassins following her, but they hold back for some reason.
Sui Ge comes up with a plan to not only confirm his cooperation with Yi Xiao, but also to surface the assassins after her. Xue Ying arrives at the capital, bringing Yi Xiao’s three little disciples.
Sui Ge tells his sister Jinxiu’s plan to have her marry the Prince of Jinxiu, Xia Jing Shi, who is in love with Yi Xiao. Sui Ge vows to protect her and prevent her marriage.
Sui Ge discovers that his sister has fallen in love with the Prince of Jinxiu and therefore wants to marry him.
Sui Ge calls upon Yi Xiao to help him find his most skilled archer, who has gone rogue, thinking to relieve Sui Ge of his burdens by killing Xia Jing Shi, the Prince of Jinxiu.
Princess Xi Yang is melancholy after learning that Jing Shi’s heart belongs to another woman.
Despite remembering past events with Jing Shi, Yi Xiao makes it clear to him that she does not harbor the same affections for him as he does for her, which distresses him.
Yi Xiao catches a glimpse of Jing Shi’s pendant, prompting memories of her falling off the cliff. She decides to stay close to him, secretly asking Sui Ge for help.
The Emperor of Jinxiu happily accepts Sui Ge’s proposal to keep Jing Shi in Susha after the wedding with his sister, as it allows him to take control of Jing Shi’s army.
Prime Minister Zhuang’s plan fails when the Emperor receives word from the Emperor of Jinxiu accepting Jing Shi’s matrilocal marriage with Xi Yang.
