The cultivation techniques and martial skills on the third floor were significantly superior to those on the lower two floors. There weren't any more lower astral grade items here. The lowest was at least middle astral grade.
However, it was a pity. Leo skimmed through several books but failed to find any upper astral grade items. It seemed like the upper astral grade ancient books and records were an extremely scarce item, even for the Zephyr Blade Sect.
Upper astral grade items weren't readily accessible, not because they were nonexistent, but because they were not easily accessible. For that kind of level of cultivation technique or martial skill, eight or nine out of ten of them were over on the core disciples side; after all, only the core disciples were the Zephyr Blade Sect's most important talents.
