Shared Heavens from Douluo Continent

The Sacred Mountain spiraled upward from its base, each complete circuit forming a level, for a total of eighty-one levels. The first fifty levels were open to outside cultivators. As long as they paid the required Spirit Stones, they could rent cultivation caves there. The higher the level, the more Spirit Stones the cave required. The caves from the fifty-first to the eightieth levels, however, could only be rented by Star Palace's internal cultivators.
