Peerless War Dragon

Betrayed by his girlfriend and framed for a crime he didn't commit, he's thrown into prison while she marries his enemy. But behind bars, a mysterious master transforms him into an unstoppable warrior. When the Dragon returns, he finds his parents murdered and his sister crippled. Now vengeance will be his—one by one, the betrayers will fall, their clans will crumble, and rivers will run red with the blood of those who wronged him.
