Crop expert Zhu Chongzhen traveled to the late Ming Dynasty. Three days later, he will ascend the throne and become the historical Emperor Chongzhen of the late Ming Dynasty. Three experimental plots of hybrid rice, sweet potato, and sorghum were planted in the back garden.
Queen Zhou: "Your Majesty, what is the use of growing sorghum?"
Emperor Zhu Chongzhen: "Of course I want the people to have enough to eat, so that they don't starve or rebel. I can lie down and die, pamper my concubines, and I will revive the Ming Dynasty."
Queen Zhou: "Your Majesty, does sorghum land have other uses?"
Zhu Chongzhen took Queen Zhou into the sorghum field and said, "Yes, Queen, it's getting dark, it's time for us to give birth to the prince."
