CPCTF_Market

Two Squirrels

My name is Mallory. I'm just an ordinary seller running a small shop on the digital asset exchange "CPCTF Market".

Sales haven't increased at all, and my account balance is a mere 1,000 CP. Right in front of me is a price tag displayed by the official shop—"The FLAG: 1,000,000 CP." It's called a legendary item, but it's a number that will never be within my reach.

That's why I need your help.

Login Information ID:mallory PW:CPCTF2026 About Alice and Bob There are two users on this marketplace, Alice and Bob. They are subscribed to shop update notifications, and whenever someone updates a shop, they immediately log in to check it out.

However, they only focus on selling. No matter what products you display, they'll just glance at the shop and log out.
