Just as the three losers were at their wits' end, Ping Pong Ball, who had remained silent all along, finally spoke:
"I have a way to let you keep observing what he does, but..."
"If you want terms for a deal, just say them. I think you've eaten too many people and picked up their nagging habits." Silver Marble said impatiently.
"Perhaps," Ping Pong Ball actually did not refute it. "My condition is that you give me one of your dogs to use."
"Any one you like. Pick for yourself," Silver Marble said directly.
White Rat and Turtle were deeply disheartened. Being called dogs was one thing—after all, aside from humans, dogs were the most successful animals in the world.
But to be valued so little, given away at the drop of a hat like a toilet tossed aside after use—this was an insult to their worth.
Ping Pong Ball looked them over, then said, "I want that Turtle."
White Rat suffered another Critical Hit. It felt that its status among the four prisoners was now surely the lowest.
"It's actually very simple. As long as we help him do things, can he still block us from observing him? Last time, he said he wanted us to gather Source Crystals, but he seems to have found other reliable helpers and has not mentioned it again. As long as we make him believe that we sincerely want to work for him, he should remember to put us to use." Ping Pong Ball explained simply.
"Oh, not bad. Even a fool may have a good idea after much thought. Actually, I was thinking the same thing," Silver Marble said, unceremoniously claiming the idea as its own. "But how do we make him trust us?"
"Of course, by submitting a Certificate of Allegiance."
