Eight years ago, a legendary martial art nearly destroyed an entire family. To protect the sacred Wuji Fist manual and a newborn heir, his parents died fighting a mysterious enemy, while his uncle fled with the boy and the secret technique. Now grown, the boy has secretly mastered Wuji Fist—but no one knows what he can really do. When a ruthless challenger storms the family dojo and defeats every fighter in sight, the quiet prodigy finally steps into the ring. One devastating punch changes everything—and exposes him to the enemy who has been hunting him for eight years.
