At the end of the Jiajing period, there was a severe drought in Guanzhong. The soul of a doctor in agriculture transformed into Zhou Qiao, the silly daughter-in-law of a farmer, and was sold to make a fortune. She used modern agricultural technology to improve winter wheat and hand-operated threshers, and led the Zhou family to escape famine to Kushuigou in Hanzhong. She opened terraced fields, built stone canals, and established a girls' school. She got rid of poverty in three years and became rich in five years.
Purpose: Let the people of the world not worry about famine
