This is a series of stories that took place in Chang'an during the period when Wu Zetian was in power and the Tang Dynasty was at its peak. The characters are all fabricated and have no historical basis. Don't be offended if it is inconsistent with history!
The inspiration comes from "Chang'an Fantasy Night" and "Young Onmyoji". The story revolves around three teenagers in Chang'an City, their confrontations and duels with some non-human species, and their own emotional commitments.
