"I don't understand." Richie hesitated and said, "Uncle Bruto and Uncle Simon just said it was almost invincible, and now you're saying it's impractical?"
"It... can't move. Yes, it can't move," Bruto answered, "because it's too complicated, so it's best to keep it in one place and not touch it. Otherwise, it can easily malfunction. Do you understand what I mean? A grain of sand falling into the magic array, a gust of wind can cause it to malfunction. I guess they definitely set up many other arrays at the core of the magic array to protect it. Also, because it's so complicated, once it malfunctions, it might take a very long time to repair. Maybe fifty years, maybe a hundred years. Repairing the array might not be difficult, but finding the cause of the malfunction would be extremely hard. It could take thousands of years."
Richie was stunned.
Simon cackled, "I've actually seen something similar."
"Where did you see it?" Bruto asked.
