Road to the Continent of Beasts
After being dropped off by their guide in the territory of the Flooded Dragons, Minos' party would travel through this maritime part of the South Sea for a few weeks without encountering any major problems.
Of course, their journey hadn't been so peaceful that the crew members hadn't had to use their skills. The most powerful environments in the Spiritual World were never peaceful.
Even if intelligent beings didn't cause problems for each other, spiritual phenomena could cause countless problems on one's journey.
At the bottom of the sea or on a floating island, anywhere rich in spiritual energy, one might encounter extreme natural phenomena that would require action from those close to the place where something like an exceptional storm or a massive earthquake occurred.
