The Sunflower Manual was written by a eunuch and was discovered by Yue Su and Cai Zifeng, two members of the Mount Hua Sect, in the library of Shaolin Monastery.
The abbot of Shaolin Monastery recognised the evil nature and inherent dangers of practising the skills in the Sunflower Manual so he sent a Shaolin monk, Duyuan, to serve as a mediator in the conflict between the two factions and dissuade them from practising the skills in the manual.
