Su Rong visited the old Duke's study, where the Duke handed her several manuals.
He sighed, "You girl, I know you need to leave soon, and there's not enough time to teach you more. These manuals contain my notes and others'. Take them, and read them in your spare time!"
Su Rong picked them up, knowing these manuals were valuable. She said immediately, "I don't need to take them with me. Give me half a day, and I'll read them all in your study. I can remember."
The old Duke slapped his forehead, "Right, I forgot, you do have that ability."
In Changzhou, when he instructed her, he discovered her exceptional memory, making her able to remember everything she saw. Therefore, he was thrilled and wished to impart all of his lifelong learning from the battlefield to her.
He waved his hand, "You better get reading then!"
Better that she doesn't take them, so he can leave them for his successors.
