Luffy: Hey, Jack, did you hear that? The price of salted fish has suddenly plummeted recently!
Jack: What? Salted fish? This is not like normal market fluctuations.
Luffy: Yes, I feel the same way. I began to suspect that someone might be manipulating the market behind the scenes.
Jack: (thinking for a moment) Are you saying that there is someone behind the scenes, deliberately causing the price of salted fish to drop?
Luffy: Yes, I don't think this is a coincidence. And this kind of manipulation may not only be for making money, but there may be a larger conspiracy behind it.
Jack: (eyes twinkling) That's an interesting idea. Shall we dig deeper and find out who is behind this?
Luffy: (nodding) Exactly what I thought! But we need someone who understands finance to help us analyze market data and trading behavior.
Jack: (laughing) Then we have to find a business wizard, otherwise this will not be an easy task.
(Soon after, they met Cheng Yaojin one night.)
Cheng Yaojin: Hey, what are you discussing?
Luffy: We are trying to reveal the conspiracy behind the market, but we need a partner who understands finance.
Cheng Yaojin: (eyes light up) This is my food! I have a strong interest in the financial field.
Jack: Do you understand financial markets?
Cheng Yaojin: Of course, I have some experience in the business world in the past. How about we work together to reveal the truth behind it?
Luffy: (smiling) Looks like we made a strong team.
