The fates of Cheng Xin, Lin Feng, and Colonel Chen are bound by an ancient agreement, forming the "Trinity" that starts or ends the cycle. They must walk on the border between madness and despair, fight against the "shepherds" and "scavengers" from higher dimensions, and engage in a desperate struggle at the rules level. Their goal is not to simply survive, but to tear apart a path of their own to "repair the sky" for the "wrong" civilization of mankind on the iron curtain of destined destruction.
