On his way to a job interview, modern young man Zhang Mingxuan accidentally transmigrated to the prosperous Tang dynasty. He had no money to his name, was starving, and had no golden finger to rely on. To stay alive, he took a menial job at a Chang'an bookshop. There, he unexpectedly discovered that this version of the Great Tang concealed a Daoist alliance and the hidden currents of a chaotic Journey to the West era. From then on, he hid among the common folk, keeping a low profile as he cautiously sought the path to transcendence.
