In the early years of the Republic of China, warlords ran rampant, demons were at large, and the Japanese coveted Chinese territory, accelerating their invasion. A Japanese Onmyoji with a mysterious mission entered China under the guise of cultural exchange, aiming to locate the Chinese dragon veins and disrupt China's feng shui to pave the way for future invasions. Led by Qi Shu, a group of Chinese folk Taoists uncovered the Onmyoji's conspiracy. Embracing their national duty, they sacrificed themselves to protect the dragon veins, engaging in a fierce battle of cunning and Taoist magic with the Japanese Onmyoji.
