In the nursing home, Qianwang Wu Shunliu often advises the elderly to stay away from gambling. One day, his bank card was deducted, and he learned that his granddaughter had been trapped in a casino to lose money, so he put on the costume of Qian Wang and went to the rescue. He rescued his granddaughter, her roommate and counselor, and proposed to pay off the debt through gambling, but was laughed at by everyone. At the fried gold flower table, he used thousands of skills to make the person who set up the game lose everything and knelt down to beg for mercy. After teaching them a lesson, he wanted to lead everyone away, but was stopped by the casino owner and asked to gamble again. When rolling dice and betting big or small, Wu Shunliu caused his boss to lose all his money and ordered him to close down the business. The boss's men retaliated. At the critical moment, his former subordinates rushed to the rescue and called him a thousand kings, but he just wanted to return to the nursing home. Later, because his apprentice wanted to challenge and threaten his granddaughter, he took action again and defeated everyone at the card table. The apprentice was punished by law and the casino involved in gangs was shut down. In the end, Wu Shunliu and his granddaughter returned to a peaceful life, leaving only the legend of the King of Thousand Kings.
