Gu Yehan, the descendant of the poisonous doctor who was expelled from his school, opened a medical clinic called "The King of Hell Does Not Accept" in the most remote alley in the capital. There is only one rule: no matter how incurable the disease is, she can save it. But the medical fee requires you to kill someone for her. One life, one life in exchange. Fair enough. Since its opening, business has been booming. There is an infatuated prince who wants to save his sweetheart and eliminates a dishonest traitor in the court; there is a peerless swordsman who wants to renew his sinews and kills a demon who is full of evil in the world; there is a wealthy businessman who, in order to survive, disperses his family wealth for her and overthrows his old enemy. Gu Yehan's "death list" is getting shorter and shorter, and her reputation is getting louder and louder, sounding like a reminder. Until that day, the famous and upright martial arts leader came to the door. He was poisoned by a strange poison and was dying soon. He had visited famous doctors to no avail. "The King of Hell refused to accept him" was his last chance. "Doctor Gu, as long as you can save me, I am willing to pay any price." The leader of the white-clothed alliance still retains his strength, but he can't hide the deathly look on his brow. Gu Yehan slowly wiped the silver needle in his hand without even raising his eyelids. He opened his red lips lightly and spoke words that shocked the entire martial arts world: "I want your position as the leader of the alliance." - I want the power to command the world to judge those who even the King of Hell cannot judge.
