Mutations sweep the world, and a tide of demons is coming! Lin Zhao struggles to survive in the apocalypse, but during a hunt, he unexpectedly awakens the “Saintess System,” which demands that he purify corruption and become humanity’s hope. But the System fails to activate, and its holy energy flows into his opponent instead: a girl known as the “Saintess of the Apocalypse.” When she points her bloodstained sword at Lin Zhao, a hint of seduction flickers in her eyes.
That is not the look of a human! Lin Zhao immediately realizes that the “Saintess” is hiding a shocking secret: she is the most terrifying succubus queen in the apocalypse! To survive and grow stronger, he takes the risk of binding himself to her Demon Servant System. By day, she is a noble saintess who slays monsters. By night, she is a bewitching succubus who pins Lin Zhao beneath her and forces him to submit. The succubus queen teases him relentlessly, but Lin Zhao has the innate ability to devour succubi! Through one dangerous partnership after another, Lin Zhao grows stronger under the succubus’s domination, going from an insignificant nobody to a “Succubus Hunter” who makes demons tremble. Yet the Saintess’s identity becomes increasingly mysterious, and her succubus powers keep mutating until they seem to touch upon the Creator God’s forbidden domain! What is she really planning?
