In the forty-sixth year of Wanli's reign, outside Datong City, the last leaf fell from the old locust tree.
Ma Gui wrote the last line in the account book - "The Jin Dynasty will be prosperous, the Ming Dynasty..."
He closed the book and said to Zhao Hu: "After I die, I will bury this book under the old locust tree. One day, someone will come looking for it."
Zhao Hu asked: "Who will come?"
Ma Gui didn't answer. He looked out the window and suddenly said: "Who made that knife? I have been searching for fifty years and finally found it."
Zhao Hu waited for him to continue, but Ma Gui closed his eyes.
Fifty years ago.
Everything starts from the winter of Datong Right Guard.
