I Bound Myself to a Destructive Witch Novel

Upon transmigration, Xia Feng discovers his heart has been replaced with a defective demon heart—one capable of sustaining life for only eighteen years. This extraordinary heart possesses a unique ability: it synchronizes with the power level of whoever it bonds with. Facing his mortality, Xia Feng makes a desperate choice and binds himself to the Destructive Witch, an ultimate villain destined to bring ruin to the world. As the witch grows stronger, so does Xia Feng, creating a symbiotic relationship that extends his life. This arrangement transforms his predicament into an advantage. Xia Feng comes to realize that his troublemaking nature serves a purpose—by constantly challenging and provoking the witch, he pushes her toward greater strength. With each increase in her power, he gains the vitality needed to survive. In his own words, he acknowledges the witch's formidable abilities while simultaneously spurring her onward: "Miss Witch, I admit you're strong, but not strong enough!"
