After his parents are murdered, Jiang Xiao Yu is separated from his twin as a baby and taken by a family friend to Villains Valley, where he is raised to be a villain by a host of outlaws, each of whom has a special skill. When he's old enough, he devises clever means to trap each of his uncles and escape the valley to head off into the outside world. A chance encounter with a beautiful girl dressed as a man leads to a treasure hunt and eventually a confrontation with the Princess of Yi Hua Palace, the one who murdered Xiao's parents in the first place. Eventually, a reunion with his twin will occur.
