The heroine Su Jingzhe was born in a poisonous family that was spurned by hundreds of immortal families. Because of her "evil and crooked" background, her beloved fiancé broke off the engagement in front of everyone at the immortal ceremony and became a laughing stock. When she was disheartened, she unexpectedly met the legendary No. 1 Immortal Ye Wuchen, who was as bright as the moon and unstained by the mortal world, but he had no cure for the cold poison in his body and was about to die soon. Su Jingzhe discovered that the natal spiritual Gu inherited from his family was actually the only thing that could temporarily suppress the strange cold in his body.
One is a "poisonous woman" abandoned by the world, and the other is a "god" hanging high in the clouds. The two reached a contract: she will extend his life, and he will protect her. From then on, Su Jingzhe stayed at Jueyunding, which all immortal disciples yearned for, and became the only "exception" around the ascetic immortal. In the process of searching for the antidote for Ye Wuchen, Su Jingzha's repressed talent for poisons was completely awakened. She refined strange poisons, controlled thousands of poisons, and trampled on those who had humiliated her one by one. And the aloof Immortal Lord also spent day and night together, and had a deep affection for this girl who had a cold appearance and a soft heart. He turned into a wife-protecting maniac and doted on her to the sky. In the end, the two not only solved the shocking conspiracy behind the strange poison, but also worked together to eliminate the scum of the Immortal Sect, and stood side by side at the top of the Immortal Way.
