Unemployed young woman Huajuan unexpectedly inherits a snack bar left by her grandfather that automatically travels back in time to the ancient era at night. To survive in modern times, she begins using modern instant foods like instant noodles and oden to trade with ancient people, exchanging them for antique currency to cash out in modern times, quickly escaping her financial plight. As her business booms, Huajuan gets acquainted with General Lu Mingli, who is tormented by anorexia, the loyal foodie soldier Mo Chuan, and others. Not only does she use delicious food to cure Lu Mingli, but she also takes in a large number of refugees during a year of natural disaster.
