Shu Qinghe, a prospective graduate of the Academy of Agricultural Sciences, stepped on the air and transformed into a small peasant girl who was about to starve to death on her way to escape from the wilderness in ancient times. The beginning is hell mode: parents starve to death, younger siblings are young, and the whole village is sallow and skinny, and they can only survive by chewing Guanyin soil on tree bark.
