In the tenth year of the Republic of China, deep in the Taihang Mountains ruled by warlords, Tanaka Jiro, the leader of the Japanese Yin-Yang Lao clan, led his disciples to sneak into Yin-Yang Village disguised as sinologists. On the surface, it is investigating folk customs, but in fact, it is secretly drawing a star map, and the five-pointed star dragon-suppressing formation is quietly nailed seven inches into the dragon's veins. When the mountain beast died violently, the children were infected with evil, and the earth's veins moved abnormally, Uncle Qi, the descendant of the Qingwei sect, opened the ancestral secret box and was shocked to realize that the thousand-year-old dragon vein had become the target of the Japanese country's "Dragon-Slaying Plan".
A battle of blood and fire unfolds at Dragon's Back: the Beidou Light Formation and Shikigami Swallowing, the Pure Fire versus the evil power of Amaterasu. Uncle Qi used his body as a lock to detonate the Nine Dragon Formation and perished with the enemy. The dragon soul stayed in the mountain forever. The golden light of dawn pierces the haze, and the Yin Yang Village returns to peace. However, lost travelers often encounter an old man in a green shirt with blurred seal characters on a copper bell - the mountain guard.
