Datang: the Emperor Visited the Street Stalls at the Beginning

Li Yi traveled to the Tang Dynasty and accidentally awakened the god-level stall setting system. Sorghum, Quyuan plow, red cannon and other cross-era products were born one after another. From then on, as the sixth prince, Li Yi put aside his status and started his career as a stall owner. Wei Zheng: "How can the dignified Sixth Prince be reduced to a merchant class!" Fang Xuanling: "The businessman is indeed inconsistent with the status of the sixth prince..." Queen Changsun: "My son has been learning court etiquette since he was a child. How could he do such a thing? Wuwuwu~" Finally, Li Er couldn't stand it anymore. "Shut up, everyone. Without the explosives Yi'er sold us, the Turkic barbarians would have invaded Chang'an City long ago!" … A few years later, sorghum was grown all over the Tang Dynasty, and everyone had a Quyuan plow. The legendary red cannon that terrified enemies conquered the world! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
