"What!" Ling Xiao exclaimed. He couldn't remain calm. Even in the Cultivation Realm, storage equipment that could preserve items in pristine condition for millennia was exceedingly rare!
A typical Cultivator's Storage Bag could store plant-based Heavenly Materials and Earthly Treasures for three to five hundred years without issue. But any longer than that, and you would need a dedicated Spirit Gathering Array made of Crystal Stones to keep the treasures' efficacy from fading before the crystals' energy was depleted. And across the entire Cultivation Realm, there were probably very few Heavenly Materials and Earthly Treasures luxurious enough to warrant preservation with a Crystal Stone Spirit Gathering Array!
And yet this world's development in the field of Storage Space had completely surpassed the Cultivation Realm... Ling Xiao was simply astonished!
