He went from a haunted house in the city to an ancient secret realm, from a different path between humans and ghosts to the love between immortals and mortals. Let's see how this Taoist priest walks between the worlds of yin and yang to find a way to the sky that not only protects the common people, but also attracts peach blossoms.
