Born with a voice that defies the natural order, Lang Wu Yao grows up isolated among snow-covered peaks. His blind mother subjects him to brutal training, driven by the hope that her son's singing will one day be without equal and reach the ears of the imperial court. However, the grueling regimen leads to a tragic accident that claims her life. Now alone in the world, Lang wanders from place to place, and unscrupulous, grasping men use his extraordinary voice as nothing more than a tool, gradually wearing down his spirit. In time, his peculiar melodies attract the attention of the princess of Xi You, and Lang is brought to the very stage his mother once dreamed of. But what waits for him there is a deadly musical duel against other performers, staged purely for the entertainment of the court. Then one day, Lang catches word of the Sword Plundering Nemesis—a notorious thief famous across all of Xi You for stealing magical weapons. What he does not realize is that the emperor has concealed the bandit's next target within the very castle where Lang has been performing.
