The Map of Secret Treasure

A few hours later, in the middle of the endless sea, Ace's small ship, encased in an invisible barrier, was sailing smoothly. 

Ace was spectacle after having a lengthy conversation with Noa and Freya, and he was also relieved that they were doing fine; actually, they were doing more than just fine. 

After he learned just how much the world has changed in these past two years, he was in disbelief somewhat. But it didn't come as a shock as well, for this was bound to happen. 

As for Noa and Freya's reason for contacting him, it was because they were worried since he wasn't returning their calls. Noa especially sounded relieved when she heard he was okay, while Freya was as smug as always, but she was also secretly relieved.
