Once he woke up from his dream, Shen Yanqing was reduced from a modern restorer of ancient books to a poor scholar on the streets of Chang'an. With a thousand years of cultural knowledge, he used his pen and ink as a blade to distinguish the authenticity of antiques, solve the mystery of inscriptions, and dig through the dust of history under the glazed tiles. With his forward-looking insights, he improved papermaking techniques and reproduced lost craftsmanship, creating a different world on Zhuque Street. When the Wenrun inkstone encounters the character of the prosperous Tang Dynasty, watch how he, in a commoner's body, makes friends with poets, immortals, drinkers, and circles around the court, allowing thousands of years of wisdom to bloom in the moonlight of Chang'an, creating a legend of the prosperous Tang Dynasty that belongs exclusively to Shen Yanqing.
