Hey, can you people give me more info on Xian Tian Gong or directly meaning with english is First Sky Gong? It's obviously an internal kung fu. It's suppose to be very strong as South Monk later proved it. And East Evil said that the 4 greats all lost to Xian Tian Gong. However, I don't seem to be able to find much info about it. You guys know anything else?
