Modern forensic doctor Su Waner and neurosurgeon Ye Qiu accidentally traveled to the Dayin Dynasty. Su Waner became the daughter of a convicted general, and her entire family was exiled; Ye Qiu disguised herself as a man and became a street doctor. As soon as they crossed over, they found themselves in a desperate situation: the Su family was about to be raided, and Ye Qiu was also intercepted and killed by the prime minister. In a desperate situation, the soul master's medical system is activated. As long as you complete the tasks of curing diseases, saving lives, and collecting soul power points, you can upgrade to the soul master realm and exchange for modern medical knowledge and cultural relic appraisal technology. In order to seize the imperial power and assassinate the emperor, the prime minister mobilized the forces of the court to block the protagonist and sent dead soldiers to intercept and kill him many times. Once the protagonist fails to be treated, not only will the protagonist be untied and killed by the system, but the entire Su family will be wiped out. After the emperor dies, the prime minister supports the puppet prince to ascend to power, and the world will fall into war. Su Waner relied on systematic inheritance to become a soul master, and used modern anatomy knowledge to help Ye Qiu accurately perform acupuncture. The two traveled together, starting from saving the Su family, and gradually established a foothold in the capital. In ancient society where men were superior to women, Ye Qiu, who disguised herself as a man, was ostracized and discriminated against everywhere. The wealthy nobles regarded them as a thorn in their side and constantly set up traps to frame them. The two of them hid their identities as time travellers, and moved forward step by step despite the rumors of the demon doctor. Each upgrade was accompanied by a life and death crisis. They had to fight against the pursuit of the clan, and also struggled with the bottleneck of soul master promotion. At first, they just wanted to survive and save the family. As their strength increased, they finally decided to use the medical knowledge and soul master power that transcended the times to break the class solidification of the Dayin Dynasty, prevent rebellion, and create a new world without the monopoly of clans.
