Ye Yu, an ordinary young man, makes a living by doing odd jobs just to take care of his seriously ill grandmother. Until that night, the nightmare came true—black shadow-like beasts invaded reality, and when grandma's life hung on a thread, an ancient jade pendant suddenly awakened and involved him in a shocking secret that spanned the multiverse.
It turns out that the multiverse is powered by the "Mother Dream Core", and the negative energy generated by the core's operation breeds nightmare beasts. After the defeat of the ancient civilization, the core was sealed in the gap dimension, leaving behind the "Guardian Seeds of the Same Origin" - Ye Yus scattered in various parallel universes.
