Set 4 years after end of The Unbeatables I.
In Las Vegas, a senior of Long Tingguang, Ye Zhong, was having a gambling competition with four other gambling sorcerers from around the world. After he won the game, the media present at the event claimed him to be "King of Gamblers". He refused to accept the title, and instead showed 4 different people on the screen and did the introduction:
* King of Deception, Long Tingguang - turned insane after he lost a gambling match to Yan Fei four years ago.
* Queen of Gamblers, Luo Qifang - rumored to be dead.
* King of Gamblers, Yan Kun - disappeared after his son won the match against Long Tingguang.
* New Generation King of Gamblers, Yan Fei - still active and his gambling skills has improved.
Ye Zhong declared that only when he beats Yan Fei on the gambling table will he be fit to be the "King of Gamblers".
Although Wenxin kept telling him that Luo Qifang is dead, Yan Fei insisted otherwise. Over 4 years, he travelled the world with his and Qifang's son, Yan Xing, hoping to find Qifang. When Yan Fei and Yan Xing got back to Coral Island, Wenxin refused to meet both father and son. As the pair stood in the rain waiting, Wenxin had series of flashbacks.
* 4 years ago, Qifang took a bullet in the head for Yan Fei. Before she went for surgery, she wanted Wenxin to promise her 2 things: let Yan Fei have the custody of their son, and if the surgery is successful, she doesn't want anything to do with Yan Fei anymore. After the surgery, Qifang lost her memory and forgotten her past with Yan Fei. Wenxin decided to fulfill her promise by faking Qifang's death, sending her to Switzerland, and giving her a new name - Huang Yuefang, and a new father - Huang Wu.
