She is Su Qingyuan, the descendant of the Medicine King Valley. Her stunning appearance hides amazing medical skills. The silver needles at her fingertips can detoxify hundreds of poisons, and the sharp eyes can solve puzzles. In order to investigate the residual poison in the fire that destroyed her family ten years ago, she entered the capital with a medicine box. However, as soon as she took action in Suzaku Street, she shocked everyone with the "Corrupted Heart Grass Antidote Technique" and also caught the sight of the God of War, Prince Jing Xiao Jue.
He is Xiao Jue, the God of War in the Northern Territory of the Tianqi Dynasty. He is handsome, cold, and unparalleled in resourcefulness. The Xuanjia Army in his hands can control the northern border. The secret files before the case are tracking down the serial strange poison in the capital. Seeing her calmly treating the fatal poison in the face of danger, and hearing her condition of "diagnosis without disturbing the patient" without being humble or arrogant, this prince, who had never had any weakness, had the idea of "exploring the mystery together" with someone for the first time.
The rotten heart and grass poison connect old cases and new troubles. The strange disease of the old lady of the palace hides a deeper conspiracy. The half piece of jade left on her waist actually vaguely matches the dark pattern of his brocade robe. Is it a coincidence, or is it a bond that was laid down ten years ago?
She used her medical skills as a blade to cut through the strangulation of power behind the drug case; he used his military power as a shield to protect her from hidden arrows while investigating the case. There is no dodder to cling to, only two strong men working side by side - she solves the strange poison around him, and he helps her find the truth about her family. In the turbulent chess game in the capital, the two go from testing each other to entrusting each other. When they finally uncover the layers of fog, they discover the shocking secrets hidden behind poison and fire. They also create a legend of two men who are "a doctor who can conquer mountains and rivers, and a love that determines the god of war".
