Night Watchman

In the bustling city, as night falls, certain 'things' always appear. Women without shadows under the streetlights, fox-faced old women, walking corpses...Whenever they appear, there are always those who stand guard in the darkness, slaying demons and monsters; these people are called Night Watchmen. The Night Watchmen always considered themselves a serious, upright organization, detached from lowbrow tastes. Until a guy named Lin Xu joined them. Lin Xu: Fellow Daoist, are you drawing talismans? Perfect, I just bought a printing press, let's try it out...Is this the legendary Mohist puppetry? Can I use this Iron Man I just bought?
