On the steam locomotive, Lu Zhiyu travelled from the main world, across the portal, and arrived at Rhode Bitwall instantly. Everything around him seemed to faded away, transforming into void and silvery white shortly, then the locomotive took all through spaces, arriving at the City of Steams in Rhode Bitwall.
Through the endless tunnels, the locomotive travelled on the rails. Alchemy lamps lighted up in the tunnel, till the sky emerged, and a major city filled with metals and machinery appeared in front of everyone's eyes.
"Wow!", shouted kids on the train, as they were captivated by the scenery. They were students of various seminary schools. Those who came here and got off were at least apprentice professionals. It was completely a world of professionals.
It was an island floating on the sky. They had travelled on rails in the air, from the top of the island, circling down the City of Steams.
