The staff nodded to the middle-aged man with a smile on her face, took his badge, and scanned the badge with a scanner specially modified by the public office. A few seconds later, the middle-aged man's personal information appeared on the laptop screen.
The staff then typed a few lines of commands on the keyboard, then looked at the middle-aged man, and said, "Sir, you have seventy contribution points. Do you want to redeem all of your points?"
The middle-aged man nodded and said, "Yes. I want to use half of my contribution points to exchange for weapons and armor, and the remaining contribution points to exchange for supplies."
After he said that, the staff opened a book, showed it to him, and said, "Sir, you can choose what you want from the list on this page."
