Lin Mu, a graduate of the College of Traditional Chinese Medicine who had lost his apprenticeship, was forced to take over the dilapidated ancestral medical clinic. On the first day, she encountered powerful people who used their power to force her to receive illegal treatment. She took out the dusty copy of "Xuan Hu Lu" and opened the first page, which warned: "Those who practice this technique will suffer from five disadvantages and three deficiencies, one of which will be widowed and lonely." Helplessly, she picked up her pen and added ink, and slowly wrote a new rule next to the instruction in the hospital that "doctors do not knock on the door" - "medicine does not cure evil." The moment the silver needle fell into the hole, the arrogant and domineering medical seeker suddenly screamed and fell to the ground, bleeding from all his orifices... And all of this is just a small test in the prologue of that weird medical book.
