Wan Yanjin, a new female medical officer at Jin Chaotai Hospital, has superb medical skills but an upright temperament. While diagnosing and treating the "cold syndrome" of a royal family member, he unexpectedly uncovered a huge smuggling chain that used sulfur-smoked low-quality ginseng to pass off as high-quality Liaodong ginseng. Faced with the tangled web of interests and the threat of "violent liquidation," Wan Yanjin chose a more difficult path: teaming up with her colleague Chen Banxia, who was proficient in pharmacology, they groped among the alchemy furnaces and medicine mills, and unexpectedly discovered the "secret of the flame color" of sulfur when it meets fire. Using the medicine box as a shield and the silver needle as a pen, she promoted the birth of the "Medicinal Materials Trade Law" and examined the pharmaceutical market with an unprecedented "chemical eye". This is not a battlefield of swords and swords, but a battlefield filled with the fragrance of medicine. See how the young female official of Tai Hospital, guided by the benevolence of doctors, ignited a fire of justice that illuminated the darkness of business. In the whirlpool of imperial power, merchants and people's livelihood, she used the wisdom of the Jin Dynasty to write an alternative legend about "authenticity" and "justice".
