In his previous life, Ye Jinghong was the last descendant of the Wan Gu Sect, the world's number one poison sect. He was a master of both medicine and poison. He was dedicated to assisting the second prince Yun Che in his fight for the world. However, on the eve of his success, he was betrayed by Yun Che and his junior sister. They cut his heart and took his blood. His poison skills were abolished and he died with hatred. When she opened her eyes again, she was reborn in the body of a concubine with the same name and surname in the Zhenbei Hou Mansion. This concubine was the stand-in for the legitimate daughter of the Hou Mansion. She was bullied by her aunt and sister and had a cowardly character. After rebirth, the soul of Ye Jinghong was the decisive leader of the Poison Sect. She changed her cowardice and killed her on the spot, starting the road to revenge. On the surface, she is an inconspicuous substitute concubine, but secretly, she transforms into the mysterious poisonous doctor with a thousand faces, stirring up chaos in the world and the court. Step by step, she exposed the hypocrisy of her aunt, and tore her aunt Bailianhua to pieces, causing unrest in the Zhenbei Hou Mansion. She gradually found out the real cause of death of this body, and found that it was inextricably linked to the enemy in her previous life. In the process, she met Xiao Linyuan, the cold and ascetic martial arts leader. The two tested each other and became friends and foes until Xiao Linyuan discovered her true identity, broke the rules for her, gave up the right path and rules, and joined hands with her. In the end, Ye Jinghong killed all his enemies in the past and present life, uncovered a huge conspiracy to subvert the imperial power, and climbed to the top of the martial arts world with Xiao Linyuan.
