"You chose the wrong path."
"I made the right choice. I don't have to be a spoiled young man. I can do something else."
"What to do?"
"Make a knife that hides in the dark."
The gentleman was silent for a moment, then took out a small inkstone from his arms and handed it to him.
The inkstone is blue-grey, fine in texture, inconspicuous, and easy to handle.
"Making a knife is too eye-catching and easy to break." The gentleman said calmly, "Make an inkstone. The ink is silent, and the words hide thousands of troops. Others see you as just a decoration; only you know how much you hide in your belly."
