The time traveler Li Qiu came to the Zhenguan period of the Tang Dynasty. He was imprisoned at the beginning and was bound to the "resistance ability becomes stronger" system. The jade pendant he accidentally exposed revealed a shocking life story - it was actually the flesh and blood of Li Shimin and Empress Changsun who had been missing for 17 years. Relying on the combat power exchanged by the system and his own talents, Li Qiu opened a tavern in Chang'an, brewed "Shenlang" wine, created special dishes, made friends with virtuous ministers and generals such as Wei Zheng and Qin Qiong, and also attracted provocations from powerful officials such as Li Ke, the king of Shu.
