Female protagonist who transmigrated into a novel called Dominion, becoming the vicious cannon-fodder supporting character of the same name. She is the legitimate eldest daughter of a marquis household whose mother died shortly after giving birth to her. In her previous life, her grandfather owned a martial arts school and her maternal grandfather ran a traditional Chinese medicine clinic. She learned martial arts and inherited extraordinary medical skills, later entering medical school specializing in Western medicine. She combined traditional Chinese medicine with modern medicine and saved countless lives before dying in a car accident. In the novel, the original Su Wan was forced to marry the impoverished scholar Gu Huaizhi after her father swapped her arranged marriage to the Crown Prince with her stepsister. The original Su Wan poisoned Gu Huaizhi's medicine, sold his younger siblings to traffickers, and ultimately died a gruesome death at his hands. In this chapter, Su Wan prevents the poisoning, fights off child traffickers using martial arts skills, and begins to clean up the mess left by the original owner.
