"In short, we just let those birds conduct the search themselves."
Hill Fawkes produced a pencil and sketched a tree diagram on a piece of paper. "Since we pay for information instead of the person who collects them, the more information he gets, the more he earns. To obtain more information, he'll find a way to hire more people to do the work for him. In His Majesty's words, it's called a top-down approach."
"I see," Edith commented, who immediately grasped the nature of this management style. "To expand the lower-level organization, we, as the stem of the tree, must give them some incentives to make sure that they keep working for us."
Hill nodded and said, "Exactly. Scouts and detectives are all at the very end of the chain. They won't change much over time. Therefore, the information would become more reliable as time progresses, although their search area can be fairly limited."
"But they're essentially Rats..." Iron Axe said, frowning.
