A Scholar of the Tang Dynasty's Zhenguan Era

Gu Qing, with a large backpack, transmigrates to the Tang Dynasty's Zhenguan era, a time of boundless charm. Surrounded by beautiful women during the prosperous Tang dynasty, he dreams of creating small inventions and living a leisurely, wealthy life with Wu Meiniang, like salted duck eggs. But alas, the second son of the Li family, the emperor, takes notice of him, forcing him to build military factories, establish academies, expand the territory, receive noble titles, and share the fate of the nation.
