After Xia Feng transmigrated, his heart was mysteriously removed.

In its place, a defective demon heart capable of sustaining life only for eighteen years was implanted.

This is a magical heart that can sync with the power level of its target.

To stay alive, he bound himself to the ultimate villain of the future, a Destructive Witch who was destined to destroy the world.

Thus, Xia Feng realized, it's not my fault for stirring up trouble: “Miss Witch, I admit you're strong, but not strong enough!”
