Yu Ping'an, who had been unjustly imprisoned for ten years, learned a thousand skills and returned to plan to track down the real culprit. From breaking up the mahjong parlor to breaking into the underground casino "Boundless Ocean", he used his superb skills to defeat conspiracies, win people's hearts, and even instigate his opponents' right-hand men. Although he was hunted down and assassinated, he still teamed up with his companions to win the Thousand Arts Competition and dominate the world as the "Master of Peace". In order to force the mastermind behind the scenes, Lao Hei, to show up, he set up a series of traps, alienated forces, secretly threatened, and finally forced the other party to the negotiation table - but the moment Lao Hei appeared, the truth about ten years of injustice was about to be revealed.
