Su Wanqing, the chief medical examiner of the modern era, accidentally exploded while performing a mission and was reborn as Princess Yi who was immersed in a pig cage. The original owner was framed for breaking up a private meeting between Bai Yueguang and Lin Ruoxue and the prince, and ended up drinking poisoned wine on their wedding night with hatred.
After waking up, Su Wanqing was carrying a mysterious medicinal spirit space, a golden needle in his left hand to save the world, and a scalpel in his right hand to break the situation. He opened a medical clinic, made firearms, and cured plagues. He used modern medicine to tear apart the hypocritical mask of White Lotus, and even stirred up troubles in the court with the art of rejuvenating the country through science and technology.
