"I have an idea."
Paul looked at him and asked, "What idea?"
"Have you heard the story of 'Who Stole the Pie'?"
This story from Su Mu is a local fable-like tale about a mother who made several pies but found one missing.
None of her children admitted to stealing it, so she came up with a plan.
She marked the pies with different colors and told the children that only the pie of a certain color was the one they wanted to eat; the others were not.
Then, in front of her children, she broke open a pie to reveal a filling they disliked.
The next day, she caught the one who had stolen the pie.
It was actually a story to inspire young children to think, because reality might not be so simple, but now, perhaps they could also make use of it.
Paul had also heard this story. He fell silent for a while, "Call people individually."
Mueller nodded and started calling people.
Paul assigned each of them a task and told them not to inform anyone.
