The Martial Immortal's Record of Subduing Demons is a tale of the struggle between good and evil, and of the unbroken chain of cause and effect. Jiang Xiaoying, an actress in a theater troupe at the heart of an ancient marketplace, is beaten to death after offending the powerful. Her spirit enters the underworld, then moves on to the Eastern Realm of Eternal Bliss. But her resentment has not entirely faded, and she continues to see the powerful in the mortal realm oppressing the common people. These visions constantly test her resolve. In the end, unable to bear it any longer, she descends to the mortal realm and starts a war. Many people become vengeful spirits in the conflict, and Jiang Xiaoying is trapped in the mortal realm to suffer because of them. After enduring her punishment to the end, she returns to the Immortal Realm. From then on, she understands that everything is governed by cause and effect, and practices even more diligently, advancing to a higher spiritual rank.
