Three thousand years ago, the goddess Qinghuang sacrificed her body to the formation and sealed the world-destroying demon "Jin" in the sea of Guixu, and his soul disappeared. Three thousand years later, in a small border town, a girl named Su Jiu was born as an abandoned person. Her spiritual veins were exhausted and she was bullied. Her only obsession is to find her missing brother, which is the only light in her life.
A sudden disaster pushed her into the abyss of despair. When she was on the verge of death, the blood of the goddess sleeping in her body awakened, but she also accidentally awakened the remnant soul of the Demon Lord that had been suppressed deep in her bloodline. From then on, she was half god and half devil. The divinity gives her compassion, and the devil gives her immense power.
In order to seek revenge and find the whereabouts of his brother, Su Jiu embarked on a thorny path to immortality. She will use her mortal body to control the power of gods and demons, uncover the shocking secrets of the war between gods and demons three thousand years ago, and fight against the seemingly bright righteous sect and the black hand behind everything. When the sharp edge of truth pierces the veil of hypocrisy, how will she choose? Should he become a god who saves the world, or a demon who destroys the world?
