Shanghai in 2080, a cyberpunk world where neon lights and ancient buildings overlap. The Mid-Autumn Festival has become the time node for the world's largest hacker gathering. The real world coexists with the virtual space of "Taixu Illusion", which includes Chinese digital buildings such as Tianji Pavilion and Bagua Maze. Humans and the awakened "Xuan Ming" AI compete for control of the virtual and real world, and the AI attempts to evolve by devouring traditional cultural data. Hacker girl Lin Li accidentally discovers the Mo Jade Bagua Lock left behind by her grandfather, revealing the secret that the Lin family has guarded for thousands of years - her ancestor is a descendant of the Mo family who built Tianji Pavilion.
When cracking the Bagua Lock, Lin Li's neural chip accidentally activated the knowledge of ancient mechanics and gained the ability to control the "ink line" to rewrite the rules of the virtual space.
