Age of Wushu? You'll need to lose your virtual junk first, as the evil-aligned sect is basically an order of eunuchs that forcibly castrate initiates.
And yes, it's in the game.
MMO Culture has all the details, including a gameplay video if you're so inclined. In a nutshell, prospective Rootless monks must obtain a special daily quest and then undergo the castration process, which features a dedicated health bar. "After around two minutes, the process will end," the site says. "However, the success rate of castration is still considered low at this time. If it is unsuccessful, the victim will still sustain significant damage." Click past the cut to see a snippet of castration gameplay for yourself.
