Neon Talisman

In "Xinghai City", a city so prosperous that it is difficult to tell the difference between day and night, the glass curtain walls of skyscrapers reflect false skylight, but the forgotten ancient aura flows in the underground pipe network. Most people are trapped in "normal" life and know nothing about the "abnormalities" hidden in the blind spots of convenience stores, fire escapes in office buildings, and deep in the alleys of old cities - there are "shadow erosions" that feed on human emotions, and there are people who guard the city's terrain. There are also a group of people called "talisman masters" who can use blood as a guide to transform modern symbols (QR codes, neon signs, electronic screen codes) into aura-driven spells to fight against darkness in the reinforced concrete jungle.
