In the urban jungle of steel and concrete, Lin Wanxing, an ordinary working girl whose edges have been smoothed by life, works overtime in a "996" Internet company during the day, enduring the infighting of her leader's PUA and colleagues. However, when night falls and the neon lights of the city light up, she sheds her disguise as a social animal and transforms into a female Taoist priest who catches monsters with the inheritance of the ancient "Xingyue Temple". She holds a peach wood sword and carries a star-and-moon compass. She walks in the shadows of the city, slaying demons and maintaining peace in the world.
