During the Republic of China, Li Chengfeng, a descendant of the Qi Men sect, reopened the "Suiyuan Hall" to practice medicine for the benefit of the world. He first broke the ominous pattern of the "Longhuai on the Tomb Top" of the Ye family's ancestral tombs, and then broke the "Earth Evil Cattle Slaying Technique" of the Japanese Yin-Yang Master to save the entire village, but thus incurred a mortal enmity with the Japanese Jiu Ju sect. Master Sato Masahiro of the Jiu Ju sect set up the "Heavenly Chop Evil" evil formation in Haicheng, attempting to sever the dragon's vital energy with a saber tower. Li Chengfeng used the secret technique of "armoring the dragon" to protect the dragon's vital energy, and invoked the Five Thunder Orthodoxy to kill Sato, who had transformed into a corpse demon, ultimately safeguarding the national fortune.
