Cruel tyrant Taxian-jun killed his way to the throne and now reigns as the first ever emperor of the mortal realm. Yet somehow, he is unsatisfied. Left cold and bereft, abandoned by all he held dear, he takes his own life...only to be reborn anew.

Awakening in the body of his younger self-Mo Ran, a disciple of the cultivation sect Sisheng Peak-he discovers the chance to relive his life. This time, he vows to attain the gratification that once eluded him: all who defied him will fall, and never again will they treat him like a dog. His greatest fury is reserved for Chu Wanning, the coldly beautiful and aloofly catlike cultivation teacher who betrayed and thwarted Mo Ran time and again in their last life.

Yet as Mo Ran shamelessly pursues his own goals in this life he thought lost, he begins to wonder if there might be more to his teacher-and his own feelings-than he ever realized.
