The
Sunflower Manual () was written by a
eunuch and has been passed down for 300 years before it came into the possession of Hongye, the abbot of the
Southern Shaolin Monastery. Yue Su and Cai Zifeng, two members of the
Mount Hua Sect, heard of the manual and plotted to steal it under the guise of visiting Southern Shaolin. One night, they sneaked into the Shaolin library to find the manual and each memorised half of the book in an attempt to copy it. After returning to Mount Hua, they tried to piece together what they had read, but the final copy turned out to be incomprehensible. Nevertheless, each of them managed to integrate what they had learnt into their existing skills, and became more powerful. However, over time, a rift developed between them, resulting in the Mount Hua Sect splitting into two factions: one focusing on swordsmanship, led by Cai Zifeng; the other focusing more on
neigong, led by Yue Su. Hongye realised the inherent dangers of learning the skills in the
Sunflower Manual so he sent a monk, Duyuan, to mediate the conflict between the two factions. Yue Su and Cai Zifeng agreed to a truce and sought Duyuan's help in better understanding the manual. Duyuan, having never read the manual before, was able to piece together their individual recollections and compiled a comprehensible version of the manual. This manual later fell into the Sun Moon Holy Cult's hands when the cult took advantage of the Mount Hua Sect's internal conflict to attack them; Yue Su and Cai Zifeng were both killed during the raid. While working on the manual, Duyuan fell under its evil influence and his mind became corrupted. He secretly created a new skill, the Bixie Swordplay (), based on his interpretation of the manual, and wrote a manual for it on his
kasaya. Afterwards, he renounced his vows as a monk and returned to secular life, reassuming his former name Lin Yuantu. His mastery of the Bixie Swordplay brought him fame in the
jianghu. The Bixie Swordplay bears similarities to the
Sunflower Manual, one of which is that any man who wishes to learn the skills must be castrated, or else he will die from
neigong imbalance. Lin Yuantu had forbidden his adopted son and descendants from learning the Bixie Swordplay and hidden the manual in the Lin residence. Both the Mount Hua Sect's copy of the
Sunflower Manual and the Bixie Swordplay manual contain only a fraction of the original contents of the
Sunflower Manual. The Mount Hua Sect's copy is ultimately taken from Dongfang Bubai after his defeat, and destroyed by Ren Woxing, while the original copy was destroyed by Hongye in Southern Shaolin. The Bixie Swordplay manual, written on Duyuan's kasaya, ends up in the hands of his descendant Lin Pingzhi, who destroys it. == Appearances in media ==
