Even in wuxia fiction, people do unlikely lifestyle and career changes all the time. Kiu Fung went from being the Chief of the Beggar's Union to a Khitan warlord. Gwok Jing went from a Mongol prince consort to leader of Chinese wulin's resistance against the Mongols. I hear that Ging Mo Meng went from killer swordsman to medical doctor.

No Flowers Monk from CHOR LAU HEUNG might take the cake in terms of doing a complete 180 in his lifestyle and career choices. He went from being an enlightened Shaolin Buddhist monk to becoming a proto-fascist dictator in the Loulan Kingdom after Chor Lau Heung exposed his role in the Jinan conspiracy. That's...quite a switch from Buddhist monk to proto-fascist dictator.
