In the interstellar era, the twin sister Mingxu (Xian) of the top scientist Ji Yun (Entropy, Qi) mysteriously disappeared.
A few years later, Ji Yun discovered that her sister's disappearance was related to the huge technological organization "Terminal Beacon" (TTB).
So she used P-ε to copy herself and pretend to be her sister, using herself as bait to set up a chess game.
Ji Yun and his companions went hand in hand. When everything settled, in the torrent of time, different first causes appeared, and then an even more shocking truth surfaced.

In the process of destroying TTB, Ji Yun discovered that there seemed to be something more than absolute trust between herself and the replica. However, did this really come from "me"?
