Lin Wan, an AI architect in the 21st century, died suddenly from overwork. When she opened her eyes again, she became a female educated youth who went to the countryside without enough to eat in the 1970s. It also comes with a half-disabled AI system "Turing", which stores a huge amount of information from the future. While others are still worrying about work distribution, she relies on AI to analyze the soil quality and achieve a new high yield per mu. While others were still taking care of themselves when they were sick, she relied on AI's medical database to become the "little miracle doctor" in the village. Others are still fighting for the place to return to the city, and major scientific research units are already quarreling over her. The whole village regarded her as a treasure. Anyone who dared to bully the lucky star of their village would be attacked with hoes. Jiang Yi, the production team leader who initially thought she was squeamish and troublesome, followed her every day: "Lin Zhiqing, it's cold, so wear long pants." "Lin Zhiqing, that guy is not a good person at first glance, stay away from him." "Lin Zhiqing, look... When are we free to get the certificate?"
