Reporter Yan Qing suddenly hears seven voices in her mind: her parallel-world selves are hunting her.
With the help of psychiatrist Gu Sen, she discovers that this is a case of “self-hunting.”
Every time she kills one of herself, she gains a memory, piecing together a more complete self and drawing closer to the truth.
When her seven selves merge, Yan Qing gains the “Mirror Eye,” which lets her see traces of parallel worlds. She becomes the “Gatekeeper,” guardian of reality and the sea of consciousness.
Then an even greater threat arrives. Ten years later, the rifts widen, and ordinary people are “replaced” by their parallel selves.
A higher-dimensional civilization known as “Yuan” descends, treating humanity like a crop to be harvested.
Her daughter, Lin Fei, was born able to transmigrate between worlds, making her prey in Yuan's eyes.
From reconciling with herself to protecting the world, from waiting for her daughter to letting her go and save three thousand worlds.
This is the ultimate question of who “I” am.
