The appraiser introduced himself to Val as Bart, then told Val, "I must admit, I am quite curious about how you managed to get your hands on such rare items. But of course, I understand if you would rather not talk about it. It's your trade secrets, and it's not my place to poke my nose in other people's business."
Val shook his head with a slight smile, his acting to the point. "It's alright. I don't mind sharing. I purified these cores myself. Also, if you happen to find customers interested in purifying cores, I would appreciate it if you could refer them to me. In return, I'll give you a 10% commission."
Bart's eyes lit up at the proposition.
"That sounds like a fair deal to me, so I'll definitely collaborate with you," he agreed, extending his hand for a handshake, to which Val happily obliged.
