Zhou Yi looked at the Crystal Bone Man in front of him: "You say you're one of the pilots of 404 City?"
"Yes."
Lin Hao nodded: "Mr. Zhou, 404 City is essentially a giant conical gemstone vehicle, with its front constantly rotating, moving continuously in the deep underground, currently advancing towards the Earth's core within the mantle."
"Because of this special structure, there are seven places inside 404 City similar to engines and control rooms, operated collectively by 7 Crystal Bone People."
Zhou Yi realized: "So, transforming you into a gemstone structure was to facilitate propelling 404 City."
"You are absolutely correct."
The Bone Man nodded: "Initially, Lord Verne had to control it himself. Later, with us, these tasks were handed over to us pilots."
Zhou Yi asked curiously: "Why are 7 pilots needed?"
