Gao Yang quietly found Antonio in a room set up like a study, while Antonio was standing in front of a floor-safe in deep thought.
Upon hearing footsteps, Antonio didn't look up and said softly, "What's up?"
Gao Yang coughed lightly and said, "How's it going?"
Antonio responded in a deep voice, "It's very complicated. This is a safe with a combination of electronic and mechanical locks, and the electronic password is twelve digits, while the mechanical lock's password is definitely different from the electronic one because it only requires six digits. Also, this safe needs a key to open. Two passwords and one key; you need to meet all three conditions to open it. What's inside must be very important."
Gao Yang said quietly, "Oh, what's here is definitely documents upon first glance. It's useless to us, so should we just leave now? What do you think?"
