So, a bit of information on the manuals. There has been misinformation circulating around the jianghu, and the Shaolin record appears to be the most comprehensive one thus far.

Wuxiang Qiankun Skill (無相乾坤功, Formless Universe Skill)
Created by a Shaolin monk who merged Buddhist and Taoist teachings. It is said to have no step at all, being formless, with its progression entirely dependent on the user to develop for itself. Due to that requirement, the risk of losing oneself during meditation – causing their consciousness to never return – is rumoured to be extremely high. It is the only method in existence that can reconcile the energies of the Jiuyin Holy Art and the Jiuyang Divine Skill.

As for the librarian, Xuezi tells you that she encountered him once close to a hundred years ago, when she still had all of her powers. He was rather old even then, but he looks a little older now. She attempted a manual raid on the Shaolin library and after single-handedly easily trashing the entire temple and the Eight Sects masters who stood in her way, was so soundly and humiliatingly beaten in front of the library that she didn’t feel like setting foot in the Central Plains until now (when she has no choice). She was of the impression that he must have been long dead by now (hence her excitement to visit the library), but after meeting him again, thinks that he must be practicing some sort of longevity neigong similar to hers.
