Yun Yu, the youngest Minister of Household Affairs in the Jin Dynasty, was born with a delicate heart, but he was also the most sick man in the capital. He had been coughing up blood for three years, and the imperial doctor declared that he would not live to be twenty-five years old, but he still wanted to hide his huge ambition in this broken body. Once the "Rejuvenation System" is awakened, you can change your luck by treating illnesses, and gain power by saving people. He smiled and coughed up blood: "My illness must be cured by the people of the world." In the court, he saved the emperor with his wonderful rejuvenation, then turned around and sent his political opponents to death; in the harem, he treated the disease with wonderful methods and won the love of the noble concubine, but secretly he planned a plan to seize the heir. The villain is a serial murderer who only targets high-ranking officials. Yun Yu takes the opportunity to eliminate dissidents while investigating the case. Under the humorous writing style, there is a bloody power game. "Sir, you are coughing up blood again." "It doesn't matter, this blood is my certificate of surrender." Let's see how the sick and weak careerist uses his good hand as a blade and his sick body as a shield. In this chess game of high-ranking officials, he will win step by step and have the last laugh.
