The deceased Lord Ren not only mysteriously “resurrects” and becomes known as the “blood demon”, but also kills several people. Police Captain Cao has no choice but to invite the Taoist Chief Qian He to conquer the evil spirit. After some magic practices, even Taoist Chief Qian He is powerless against the spirit. Following the threads of clues, Mao Xiaofang, a Mount Mao Taoist Priest, gradually discovers the truth of the matter. The mastermind behind the “blood demon killing” is actually Taoist Chief Qian He.

Mao Xiaofang and his disciples follow the clues and track down the hiding place of Taoist Chief Qian He. After a fierce life-and-death struggle, they finally subdue Taoist Chief Qian He, making him confess to his sins and face legal punishment…
