Super Detective in the Fictional World

Luke didn't care if he was joking or not. Only those who didn't have an opinion wouldn't open their mouths.

He nodded. "Then let me give you a joke reply: If you're willing, I can pay you a ton of gold in one go, or give you a gold bar every month. Consider it… a small toy."

Carter Slade: … If Mephisto had been this generous back then, would he have considered it?

This was a hypothesis with no answer.

He could only shake his head. "I'm just kidding. I don't need gold or cash."

Luke nodded. "Then you can treat it as a joke. However, I'll give you a million in cash. You can use it whenever you need to. No matter how much you use, I'll top it up the following year."

Carter Slade: "…I don't need it."
