In the center of Vic Island (just outside of Sleepywood) you can take a boat to Orbis, and them from Orbis to Mu Lung.
Alternatively, and also much quicker, you can choose to instead take a boat to Edelstein, and then from there a boat to Orbis. Difference being that it costs you a very small amount, is a few minutes quicker, and adapts to your schedule. --- "I'm gonna match my in game snacking to my real life snacking. Acid. Morphine. Coke.
