There Is a System for Traveling Through the Tang Dynasty

I accidentally traveled to the Tang Dynasty. I didn't have any other skills, so I had to start my old business, selling barbecue. I didn't have all kinds of seasonings. Don't people in the Tang Dynasty eat barbecue? Business was bleak, and I was bullied by street bullies, until one day the system appeared, woo woo hoo, I was finally going to live a good life in the Tang Dynasty. I was the worst person who had ever traveled through time and space. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
