The crust is the two to three thousand miles of the shell wall you entered, which is also where the Unihorn Tribe resides.

That's why you don't see many Unihorn Tribe people here; the few you do see are just the prison guards on duty."
He pointed to the ground beneath him, "This second part, well, consists of islands one through nineteen, mostly used to imprison the cultivators. The environment is quite similar, as such relatively enclosed spaces rarely show starkly different terrain or landscapes.
Only the nineteenth island is not used to hold people but serves as a trial arena with another function."
