The film tells that Yan Xian's master passed him a demon catcher before he died, but the demon catcher was stolen by the three cat demon. The stranger caught the "demon in the ear" inside the king. Yan Seventeen caught a rat demon who had stolen his money and treasure, and this rat demon named Rat Laibao was the real successor of the demon catcher.
Sorry, but for now we weren't able to find movies like The Love of Immortal.
