Adjusting the Necromantic Space and adding another island was naturally a major undertaking.
Even with Chen Yu's Demigod Level strength, completing these tasks would require considerable effort, so to save some time, he naturally enlisted Jounouchi Hiromi to help him. As for his Ship-girl subordinates, they had other tasks.
When Chen Yu saw that Misumi Mikoto's summoned Chitose Sisters possessed casting abilities, he had already thought about summoning new Ship-girls with magic casting powers. However, due to some reasons, he decided to put this plan on hold temporarily.
After serious consideration, Chen Yu planned to summon the four aircraft carriers: Flying Dragon, Soryuu, Shoukaku, and Zuikaku from the Former Japanese Navy. But the wrecks of these four carriers still lay deep in the ocean, requiring time for salvage.
