Under the World and on the Rivers and Lakes

There is no court here, only the rivers and lakes. Under the sky, there are three mountains and one sect. In the Jianghu, there are six sects, nine sects and ten families. If you are not innate or a master, don't enter the world of martial arts lightly. However, there are rivers and lakes everywhere. Etc! Is this martial arts? Why am I cultivating immortality?
