The world of Granaxx was about the size of Earth, so as an Immortal that flew through the ocean, it would take Iris about 3 hours to reach land, assuming she was at the furthest point away from any single piece of civilization.
Ning flew along with her at a leisurely pace, doing nothing but following her. From time to time, beasts would pop out of the ocean to harm them, and depending on the beast's strength, Ning would either deal with it or let Iris handle it.
Iris got into some very gruesome fights where she had to give it her all to beat the aquatic beast. Other times, she watched as Ning got rid of a stronger beast with merely his thought.
She wondered if she could ever get as strong as him. After a few hours of flying, she finally found a flying boat that going in roughly the same direction as she was, so she stopped to ask.
The people of the ship suddenly got on alert, wondering if she was a bandit that was around here to rob them.
