Super Card System

I just got home now. I’m really tired today. I’m sitting in front of the computer thinking about codewords, but my mind is blank. I’m not in a good state. I guess I’m afraid I won’t be able to write them tonight. Don’t wait, let me slow down. Right.

PS: It may also be because of a cold. It rained today and the temperature dropped a lot. I take some medicine and take a break.
