Due to her incomplete memory, the heroine Yun Zhi relied on fragmentary clues to sneak into the dangerous demonic realm, approaching and testing the demonic abyss. She used witchcraft and wisdom to deal with the suspicion and pursuit of the Demon Lord, and gradually pieced together the memory fragments, but found that all the clues pointed to herself - she was once the supreme "dream weaver" who could weave, tamper with and even delete memories. Thousands of years ago, in order to seal a spiritual catastrophe that could destroy the world, she used forbidden witchcraft to tamper with the memories of all relevant people, including Chong Yuan, at the expense of herself, and erased her own existence from history. Now that the seal is loosened and catastrophe strikes again, Yun Zhi must choose between finding himself and accepting his fate. In the confrontation and entanglement, Zhong Yuan gradually sees the truth and falls into the painful contradiction between protecting the people in front of him and obeying the tampered "past". The core excitement of the story lies in the shocking reversal of the heroine's identity, the equally matched battle of wits and love with the Demon Lord, and the sense of suspense in which the truth about the world is revealed step by step.
