Where can I learn the playboy without sects in Jiuyin Zhen Jing?

At present, there is no "playbook", and the internal skills without sects are now two levels behind the eight sects. For example, at present, the eight schools are all in the four-level stage, but there are only two "Bing Xin Fa" without schools, and the "Hua Xin Fa" is said to be a three-level method, while the "Xuan Bing Fa" is a four-level method. Of course, all this is decided by snails. Snails have developed too little without sects, and put all their energy into 99 martial arts and 65438+.
