What does wild silkworm mean?

1, Synopsis: Yunfei (Xu Shaoqiang), the handyman of Wudang, is the illegitimate son of Song Qing (Wang Rong), the head of Wudang. Because of the rules of the gate, Song Qing couldn't recognize him, so he had to hide his identity and secretly teach Yunfei martial arts. 20 years ago, Yandang World War I and Shahukou World War I were both defeated by the invincible door owner Dugu Invincible (Wan Ziliang), and Guan Rifeng Song Qing was also defeated by Dugu Invincible, but Invincible was afraid of the "wild silkworm skills" of Senior Yan, so he had to meet again two years later. Two years later, Song Qing accepted Fu Yushu (played by Liu Yong) as an apprentice. How do you know that the master of Xiaoyao Valley, Sun Zifu of the Emperor of Heaven, only entered Wudang for revenge and stealing the stunt "Wild Silkworm Skill"? Fu Shizhen assassinated Song Qing, framed Yunfei and took over as the head. Yunfei was therefore hunted down. Fortunately, Dugu's invincible daughter Du Gufeng (Yang Jingjing) came to save her and took her to see her mother Shen Manjun. Yunfei learned that Song Qinghe and Dugu were rescued by Mrs. Shen after the defeat and injury, and spent the night with the drunken Mrs. Shen. Du Gufeng is Yunfei's half-sister.
