The longer Mo Ran spends in his life reborn, the less he understands the man he once was, to say nothing of the teacher he so hated. As emperor of the mortal realm, Mo Ran loathed Chu Wanning with all his being, but the Chu Wanning of this life has sacrificed himself for his student’s sake time and again. Nevertheless, with the day of Chu Wanning’s greatest betrayal on the horizon, Mo Ran clings to his hatred and his hopes: he must not let the past repeat itself. Yet strange new tragedies continue to unfold, and Mo Ran finds himself working alongside Chu Wanning to hunt down the mysterious culprit—a cruel mastermind who may know more about Mo Ran than even he remembers.
