By vanquishing evil and eliminating supernatural threats, he accumulates heavenly merit to temper himself and break through to higher levels of cultivation. By day, he mingles among ordinary people to make a living; by night, he wields his sacred powers to subdue malevolent spirits. Thus begins a legendary tale of hidden Daoist treasures and demon-slaying in the modern city!
