The husband lost the last half of his land, leaving Shen Hengzhi with a mute child and a lot of bad debts. The people in Shapo Village laughed at her as she was crazy - it was better to wait for death than to farm in the desert. But they didn't know that Shen Hengzhi could see the weather three days later. Before the sandstorm hit, she planted grass squares overnight; when the whole village knelt down to pray for rain, she had dug a reservoir in the underground river. What's even more amazing is that the picked-up child, Lu Yanzhou, has a photographic memory and can write down a Thousand-Character Essay from memory after reading it three times. While she was growing alfalfa and watermelons under the yellow sand, she was helping him study. When an evil neighbor comes to grab water, she predicts in advance that the well will dry up; when the clan leader wants to seize his land, she predicts that heavy rain will destroy his granary. Three years later, the county magistrate came to Shapo Village in person to list a twelve-year-old boy. Everyone is asking: How did that peasant woman do it? Only Shen Hengzhi knew that every prediction left traces on her body. But as long as she could send an inkstone boat to the Qionglin Banquet, she would risk her life.
