Not very far into the desert itself were the crumbled ruins of a temple, which was the entrance to a necropolis that stretched out under the surface of the city.
The necropolis was huge, almost half the size of Sky City itself. All sorts of rare beasts, immortal grasses, and spirit plants grew there. It was a source of abundant resources for cultivators.
The ruins of the necropolis were the only place where disciples could go on missions inside Sky City itself. In fact, many of sect missions required that disciples go there.
It was a special place, much safer than locations on the outside. Although it was indeed the ruins of an ancient necropolis, it had been put there by the Starry Sky Dao Polarity Sect for the express purpose of allowing disciples to train.
