"I was unaware that treasures grew in strength the longer they were on their own," Tony said as he thought through history to find examples of it.
"It's not something that's easy to figure out," Ning said. "After all, what would you compare it to? Unless you have the same two treasures, you can't compare them two. And since a treasure is always unique until destroyed, you have no method of learning how they differ, so you don't know."
"How do you know about all of this?" Tony asked. "Are you a historian? You knew about the corals too."
"I am… going to answer that question of yours sometime in the future," Ning said. "For now, just listen to my words and know that they are true."
"Sir Ning," Tim spoke up. "What does it mean for a treasure to be stronger? A treasure can only do one thing, so does it become better at doing that?"
