Luffy: Hey, Jack, have you heard? The price of salted fish has suddenly plummeted lately!
Jack: What? Salted fish? That doesn't sound like normal market fluctuations.
Luffy: Exactly, I thought so too. I'm starting to suspect someone might be manipulating the market.
Jack: (pausing to think) You mean someone is pulling strings behind the scenes, deliberately driving down the price of salted fish?
Luffy: Right. I don't think this is a coincidence at all. And this manipulation might not just be about making money. There could be a much bigger conspiracy behind it.
Jack: (his eyes flickering) That's an interesting idea. Should we investigate and find out who's really behind it?
Luffy: (nodding) That's exactly what I was thinking! But we need someone who understands finance to help us analyze market data and trading behavior.
Jack: (smiling) Then we'd better find a business genius. This won't be easy otherwise.
(Not long afterward, they met Cheng Yaojin one evening.)
Cheng Yaojin: Hey, what are you two talking about?
Luffy: We're trying to uncover the conspiracy behind the market, but we need a partner who understands finance.
Cheng Yaojin: (eyes lighting up) That's right up my alley! I'm very interested in finance.
Jack: Do you know the financial markets?
Cheng Yaojin: Of course. I have some experience in business. Why don't we work together and uncover the truth?
Luffy: (smiling) Looks like we've got ourselves a strong team.
