Transmigrate and Open a Shopping Street in Ancient Times

Wen Ying unexpectedly transmigrates into the body of a woman in an ancient rural village, just as a bitterly cold winter sets in. At home, she has a husband with a bad leg and three children whom the original owner mistreated. What? There are floods, plagues, famine, and scorching heat still to come... Wen Ying: What a disastrous start. Ding! Your shopping System is now bound! No need to panic, your golden finger is here to help! A supermarket, clothing store, food shop, milk tea shop... Wait, how did I end up opening an entire commercial street in ancient times?
