When bioengineer Shen Yuan was inspecting the protective shield in New Atlantis, a swarm of rampaging deep-sea anglerfish formed a fetal shape in front of his eyes. Twelve years ago, his father turned into a crazy wall-gnawer during the Kuroshio Incident. Now, inside the diving suit of his father's remains, he found an embryo map that exactly matched his own genetic sequence. This underwater city bred from a coral womb is undergoing horrific transformations - salmon are growing human teeth, protective shields are leaking amniotic fluid, and the gill slits on the backs of the residents' necks are leaking fishy-sweet mucus on full moon nights. In order to pursue the truth behind his mother's disappearance at the scientific research station, Shen Yuan and the psychoanalyst Beluga carrying orca hormones sneaked into the restricted area of the abyss, where they witnessed the Church of the Deep Sea sewing believers and worms into a pulsating cocoon of flesh. When hundreds of millions of pale umbilical cords carrying genetic codes emerged from the submarine rift, he realized that he was the living key chosen by ancient beings, and that what was conceived in the Mariana Trench was an embryo of the universe that human cognition could not bear.
