What is the concept of the Supreme Sword Body?

It is the physique that every swordsman dreams of having. It's not just one in ten thousand; you probably won't find a second one in the entire Taixuan Realm.

Originally, it was thought that Ye Zhiqiu had struck it lucky, but it turns out Chen Changan was just as fortunate.
