Upon transmigrating into this new world, Xia Feng discovers his original heart replaced with a defective demon heart—one with a fatal flaw: it can only sustain his life for eighteen years. Yet this cursed organ possesses an extraordinary ability: it synchronizes with the power level of any being it binds to, growing stronger as they do. Facing certain death, Xia Feng makes a desperate gamble. He binds himself to the Destructive Witch, a formidable villain prophesied to annihilate the world. As the witch's power surges, so does his own. With each breakthrough she achieves, his survival hangs longer in the balance. Xia Feng soon realizes the truth behind his reckless provocations—provoking the witch is not merely impulse, but strategy. "Miss Witch, I acknowledge your strength," he taunts, "but you're not powerful enough." His fate is now intrinsically tied to hers: her ascension is his salvation, her strength his lifeline.
