I Sold Milk Tea in Ancient Times

What can a milk tea shop owner do if he travels back to ancient times? Of course they still sell milk tea. As a tea-picking girl whose parents both died, living in a dilapidated house, eating porridge, soup and wild vegetables, and dragging a sick and cheap younger brother with her, Lin Nianshu collapsed. Others who traveled through time were either young ladies or palace concubines. It would have been a lot of trouble for her to wear it. But what else can we do? Let's just make do with it! Fight the best, fight against evil relatives, pick and fry tea... And so on! Seeing everyone drinking tea and even eating the tea leaves, Lin Nianshu learned to give it a try and smashed the cup. Teach the world to drink tea, make milk tea, sell milk tea... The career is booming and the days are prosperous. But my cheaper brother seems to have suddenly become very different in height?
