Before Qi Nongxi, a direct disciple of the Sword Master, went down the mountain, her master gave her two things -
First, the sword must not be pointed at the weak;
Second, protect the safety of King Huainan I.
King Qin Zhang of Huainan had a fiancée. He swore to protect her when he was very young. However, his mother-in-law left Beijing in anger and took his fiancée away. He thought he would never have a chance with his fiancée in this life, but he didn't expect that on the way to Kyoto to celebrate his birthday, his fiancée shouted "protect the prince" and fell from the sky together with an ambush assassin.
Qin Zhang: Well... Long time no see.
Qi Nongxi: The daughter of the people arrived late to save me. Your Majesty, please forgive me!
Qin Zhang:...(My fiancée whom I have missed for many years doesn't recognize me anymore)
The chivalrous woman who never loses in a fight is careless, and the prince who has been pretending to be sick for many years behaves cautiously, and the man chases the woman.
Concept: The male and female protagonists travel together
