Shen Zhixian, a college student in the 21st century, woke up and found that he had traveled to the Korean battlefield in 1950. Accompanying her is a mysterious system, which tells her that her mission is to open a small supermarket on the battlefield to provide supplies and warmth to the soldiers, helping them live and fight better. Shen Zhixian must complete this task without changing the course of history. After the war, she will get the chance to return to modern times and receive a bonus of 1 billion.
