The apocalyptic island survival trial begins, with contestants from around the world sent to dangerous deserted islands. Su Miao draws the most inconspicuous starting talent: Affinity +1, and everyone underestimates her. While others fight ferocious beasts to the death, she picks up an unremarkable little black sea monster on the beach to keep her company. The little creature is gentle and clingy, and Su Miao treats it like her own child, caring for it attentively. But when fierce beasts surround the settlement and danger strikes, every giant beast kneels in submission before the little creature in her arms. Only then does she realize that the creature she brought home is the supreme ruler of the deep sea, who commands all the oceans.
