Zhenguan Grocery Store: Save Queen Changsun at the Beginning

A top student at the Modern University of Traditional Chinese Medicine and a history enthusiast, after an accidental car accident, traveled back to Chang'an City in the first year of Zhenguan (627) of Emperor Taizong of the Tang Dynasty. In the early years of Zhenguan, he became the owner of a grocery store on the verge of bankruptcy in the corner of Chang'anxi City. Just when he was worried about his livelihood and an unfamiliar era, the "Civilized Fire Grocery Store System" was activated! Looking at the dazzling array of but expensive "gods" in the system mall - refined salt as white as snow, crystal clear sugar, "miraculous medicine" that can reduce fever and inflammation, blueprints of steel knives that can cut through iron like mud, grains with astonishing yields per acre... Li Heng realized that this was not only an opportunity to survive, but also the key to changing history! He knew very well that just a few years later, the virtuous Empress Changsun would die prematurely due to illness, which would become a huge regret for Li Shimin and the early Tang Dynasty.
