Saleen's Floating City did not fly by for fear of causing unnecessary trouble. The Floating City was sturdy, but the number of magic cannons placed at the Palace at Sea was simply too many. Saleen had no intentions of fighting Grand Duke Iron Blood.
However, the Floating City's land area was simply too huge, and parking it near the Palace at Sea would pose a threat to the place as well. The reason why Saleen made such a request was to gauge the Grand Duke's reactions. The Grand Duke agreed to it and he made up his mind to fight Alchemy City. The assault would require them to mobilize naval forces.
Attacking from the sea would make the Floating City a makeshift giant warship. The Ancient looked like a toy beside the Floating City.
