Traveling Through the Tang Dynasty, Counting Down, the System Vendor!

Modern young man Wang Yifeng accidentally came to Zhenguan for three years and found that he could only stay in Chang'an for twenty days. In order to gain a foothold during this period, he set up stalls in markets with the help of modern supplies he brought. Refined snow salt, soap, matches, water purification tablets, drought-resistant wheat seeds and other items gradually changed the lives of the people around them. While he got to know the market of Datang, he also helped the disaster-stricken people, orphans, widows and poor villagers. As his business unfolded, he attracted the attention of many people and became involved in disputes between merchants in the West City, palace officials and local forces. Twenty days are limited. Before leaving, Wang Yifeng must use his own way to save more people and fight for a glimmer of life for himself.
