This is a beautiful era. Secret skills and techniques are made public for free. As long as you want to learn martial arts, whether it is supreme secret skills or basic fists and kicks, you can find them at will.
This was also the cruelest era. Although the techniques were made public, resources and inheritance were never equal.
