At eighteen, Jin Lan was lured into the Wanjing Casino and didn't escape until she'd paid for it in blood. She married Nie Fu, an honest man, hoping for a quiet life—until their wedding day, when his oldest friend set him up to lose three hundred thousand. To save them, Jin Lan revealed the skill she had sworn to bury and won it all back in a single hand. That hand drew the police's attention. Now she goes back inside as bait, facing the casino's Four Kings one by one, until she and the law bring the whole house down. With the syndicate destroyed, she and her husband finally get the quiet life they were promised.
