Mingchuan is the chief genetic doctor of the deep-sea settlement "Atlantis". His responsibility is to protect the residents' "deep-sea adaptive genes." But he discovered that the leader of the settlement, "The Emperor of the Sea," was secretly conducting a taboo "animal transformation experiment" in an attempt to transform humans into bloodthirsty deep-sea warriors.
When Mingchuan found out that his dependent sister was selected as the next batch of experimental subjects, he decided to resist. In the desperate situation of being hunted, he activated the "source code replicator" hidden in his body, completed tens of millions of genetic iterations in one second, and gained adaptability that surpassed the behemoths of the deep sea.
He not only has to stop the experiment and fight against the high-pressure rule, but he also has to face the unknown giant creatures awakening in the deep sea-these creatures are being attracted by the animalization experiment. Mingchuan must make a choice between adhering to the bottom line of humanity and survival of the community: to become a cold-blooded savior, or a martyr who retains his humanity? Under the deep sea, genes are weapons. Is human nature just a burden on evolution?
