The Seven Deadly Sins of Dark City

Is sin a curse or a vaccine for the evolution of civilization? The Seven Deadly Sins trial is not a punishment from the gods, but a "self-examination program" left by ancient civilization - testing whether humans can control pride, greed, lust, jealousy, laziness, gluttony, and rage, instead of being enslaved by them. Lu Chen and Cheng Xue, a pair of "twin mirror images" bound by genetic experiments, witness the deepest shades of human nature in the living Tower of Babel: the glutton uses his body to protect children, the arrogant uses the password of a painting to guide redemption, and the greedy turns back time just to see his dead wife again... They discovered that the "eighth sin" beyond the seven deadly sins was called "the ability to choose." Can this tiny bit of free will reverse the tide of civilization being swamped by genetic destiny? When the choice comes, will you pick up the scalpel to dissect fate, or will you become fate itself? A dark epic about sin, civilization, maternal love and free will.
