Rich sighed. "My teacher told me that in the profession of hacking, you would only be a good hacker when others don't know that you are a hacker. Otherwise, you are a failure, because you won't have any way of protecting yourself in the real world. He used himself as an example to warn me."
Xu Cheng: "Have you seen what your teacher is capable of?"
Rich: "No. But, he made me into the hacker I am today, and that's enough to prove his skills. But unfortunately, for the rest of his life, he could only instruct me into writing the codes he wants for himself, but I would always fall behind his tempo. But, I can see how much he desires to touch the keyboard again. He said, he would never forget the feeling of typing again, just like his first love."
