Twenty years ago, the world's greatest martial master was betrayed by his own disciple. His son and daughter-in-law were murdered, but revenge had to wait. With his dying son’s final wish—to protect his granddaughter—he sealed his power, changed his name, and endured every humiliation in silence. For twenty years, he never struck back. But the promise has finally been kept. Now the seal is broken, and the man everyone thought was powerless is back. This time, every enemy who wronged his family will kneel before him!
