"Do you know she sometimes moves on her own?"
William waited as the words settled inside of him before he asked slowly.
"And that isn't a cause of worry because…"
"Because she is surrounded by the world's best cage. The steel walls themselves can generate up to 10 billion volts. That's similar to 10 thunderbolts."
"And even if that's not enough we also put runes surrounding her body and some of them are also on her body."
"And even more so we put anti gravity field machines under the giant centipede so that it would also have trouble trying to move if it tried."
William heard all of that and nodded multiple times then he said.
"So all I hear is that there is a giant centipede that could maybe destroy the whole society above it if it ever woke up from its slumber and you put steel bars around it, drew up some drawings and put some machines under it that was supposed to make the thousands of ton heavy beast only slightly heavier."
