Born into the immortal realm, Shen Li grew in power, her skill on the battlefield eventually earning her the title of General Bi Cang. Pressured into a political marriage against her will, the general chose to fight for her freedom rather than accept the match. Sustaining injuries, Shen Li reverts to her original form and falls into the human world as a phoenix where she is picked up by a mortal vendor and sold as a plucked chicken at a local human market to the sickly Xing Yun, who is unable to pass by the plucked chicken he sees caged at the human market. With that single purchase, Xing Yun links his fate with Shen Li's and love is born. Passing through the three realms and time, just as things are saved and reborn, in a small corner an ancient evil is being revived. With a stunning betrayal, Shen Li's world is turned upside down, but her stubbornness and fierceness will not stop her for seeking revenge and the truth. Going against Natural Law, their love becomes both their strength and taboo. As more secrets are revealed, will they ultimately win against evil and save the three realms from utter destruction? What will happen to their eternal love?
