I am the piano master of Prince Yong's Mansion. The fourth master allowed me to play the piano in the hall, but he never looked at me.
He thought that I could only play "High Mountains and Flowing Waters" and that I didn't know how to maneuver and conquer. Until that night, I opened the bottom of the piano case and pulled out the secret guard token. When the Fourth Master was captured, I finally whispered to him: "Master, do you know why the Emperor only loves "Guangling San"?"
The moment his pupils shrank suddenly - I cut the rope that tied him.
