The blood feud between the massacres of the village has not been settled, and her mentor has disappeared mysteriously. The orphan girl Qin Xi carries a jade pendant with the word "Shang" in her arms, and uses herbal and poisonous skills to make her way into the world, vowing to uncover all the mysteries.
Due to a misunderstanding in Yunzhou City, she got acquainted with Shang Jin, a son of an aristocratic family who had a gentle appearance and was secretly investigating his life experience. Later, the ranger Lin Ye and the heir to medicine and poison Su Wan joined one after another, and the four-person team broke into the ruins and Douying Pavilion to find out the truth between life and death: Qin Xi's ancient tribal bloodline, the secret of Shang Jin's illegitimate child, and the Su Wan family's injustice all pointed to a mysterious organization...
From the south of the Yangtze River to the extreme north, they used swords to break the situation, guarded each other with trust, and finally destroyed the conspiracy and comforted the dead. Qin Xi and Shang Jin also worked together through thick and thin, and their love became a destination.
