I, the governor of Jinyiwei Town, picked up a history textbook three hundred years in the future when I ransacked my house. The book says: Three months after the Ming Dynasty fell, the person who destroyed the country was my honest master who reads the account books every day. I didn't believe it until the prophecies came true one after another. When I put the dagger against his neck, he sneered and opened the account book: "Do you think I am settling accounts? I am calculating God's will."
