In the third year of Zhanghe's reign in Dajing, three cases of officials "suddenly dying from old illnesses" caused unrest in the court. The newly promoted embroidery master Shen Yan was ordered to investigate the case, but he smelled a familiar medicinal fragrance in the relics - it was the cold star grass that only grew in the Hidden Mist Valley. It was also the last thing that his father held in his hands before he committed suicide ten years ago after being unjustly committed.
In order to pursue the truth, he disguised himself as a sickly scholar and sneaked into the Hidden Mist Valley, where he met Su Wei, the only doctor in the valley. This man has great medical skills, but he cherishes his words like gold. He dismisses people with just a few sentences, but there are hidden secrets in the prescriptions that no one can understand. What's even weirder is that all the officials who died suddenly seem to be closely related to a mysterious herbal medicine in the Hidden Mist Valley.
Shen Yan's suspicion gradually grew, but during his testing, he discovered that Su Wei had a similar obsession to his own hidden in Su Wei's eyes - he was the only survivor of the murderous murder case in Hidden Hidden Valley ten years ago. When the shadow of the court's intrigues spreads into the valley, the sword of the embroiderer and the medicine of the doctor will finally find a way to clear up the situation for their fathers and break the situation for themselves in the heavy fog.
