In 2075, a red meteorite hit the earth and triggered the "Big Crunch". Human civilization was on the verge of collapse due to space-time rifts and genetic pollution. Doctor Chen Mo has a blood-colored tattoo on his wrist, and his "compassion scale" actually quantifies morality as a bargaining chip for survival - saving lives and healing the wounded can accumulate healing energy, and surviving in death can awaken the killing power. When he was forced to choose between the mycelium-eating mother and the mutated doll, every 1% drop in the scale meant that he was one step closer to the abyss of transformation into a cold-blooded tyrant.
In this Doomsday Judgment, the new nuns armed with shotguns and crosses hunt down the "Zero Zeros", the genetically modified Chen Wang leads the scavengers to dismember the same kind, and the Coke cans with human eyes growing out of the convenience store refrigerators are witnessing the final collapse of civilization's conscience. Chen Mo gradually discovered that he and countless "mirror selves" jointly carried the god-killing gene. Those "selves" who jumped from the hospital rooftop, were transformed into cocoons in the laboratory, and even turned into credit card faces and wandered the streets were pushing the bloody balance to the extreme of annihilation.
When the causal blade formed from the tattoo liquid pierced Sister Lucia's chest, and when the Scale Zero Alliance concluded a blood contract in the pile of carrion, Chen Mo finally understood the front page of the "Jinling Daily" that his mother burned before her death - in the 1989 archaeological team photo in front of the bronze door, the red cross birthmark on his parents' necks was the initial code of this human experiment across time and space.
