The Archmage Vanquishes the Villain

The Archmage, the sole survivor in a world that has fallen into ruin, gambles everything and manages to return to the world before its destruction. However, he finds himself not in his original body, but in the body of Lee Jin-woo, the worst villain and a third-generation chaebol heir with brilliant talent. Using his memories from before the regression, he begins to vanquish the villains one by one.
