Su Zhe, a doctor of modern agriculture, traveled through time and became a prisoner in an unjust case and was thrown into a sky prison. In order to survive, he silently wrote "Essentials for Elevating the People" in exchange for a bowl of porridge from the jailer Zhao Hu. Unexpectedly, Zhao Hu knelt down and begged to be his disciple. Warden Yuan Zhong secretly handed him a pen and paper. Chen Shouzhuo, a prisoner on death row, helped him open his joints. Even Zheng Qiuniang, the daughter of a grain merchant, gave her dowry in exchange for agricultural books... An ancient book stirred up the court.
