Three years ago, the one hundred and seventy-three households in the Zhenguo General's Mansion were stained with blood, and all of them were executed. As the only surviving legitimate daughter, Gu Qingshang, she crawled out from the pile of dead people with blood and mud embedded in her fingernails. Three years later, there was a medical doctor named "Shen Qi" in the capital who could compete with the King of Hell for people with silver needles. Everyone said that Dr. Shen had the heart of a Bodhisattva and took nothing from the poor people. He was an immortal living in the world. Only Shen Qi knew that half of her medicine box contained good remedies to save people, and the other half contained poisons that would send people to hell. Every bit of her reputation paves the way for revenge. Every rescue she performs is a ploy to get closer to her enemy. The Minister of the Ministry of Civil Affairs has always been in trouble, so she entered the government with her "unique acupuncture method" and conveniently replaced his letters of collaboration with the enemy. The deputy commander of the Forbidden Army loved her son as much as her life, so she saved her son from "danger" and made him willing to become the knife in her hands. The high-ranking imperial concubine wanted to have an eternal appearance, so she offered "immortal jade dew" and chipped away at the foundation of her mother's family bit by bit. She thought her heart was as solid as stone, until the commander of the Imperial Guard, who always had a dark face but appeared every time when she was in crisis, pushed a bowl of steaming Yangchun noodles in front of her. "Doctor Shen," the man's voice was low and his eyes were as sharp as an eagle, "Your hands are used to save people. Don't get too much blood on them." Gu Qingshang lowered his eyes, looked at the clear soup in the bowl, and laughed softly. "Master Xiao, I save people, but I also kill people. Do you... Want to arrest me?"
