Hearing this, Lady Hua nodded like it was expected and without looking around or trying to identify where her Spatial Devices were in the pile of loot and scraps Di Tou had not too far away from her, she said calmly, "I can only remove the restrictions on two of the Spatial Devices. The rest are either too high or low quality for me as the owner to remove the binding."
Although this was a bit unpleasant to hear, it indeed made sense. Security systems on Spatial Devices weren't something that were created for fun, and weren't always entirely under the cultivator's control. The lowest quality of Spatial Treasures wouldn't have any protection at all. Somewhat like the Spatial Bags that Di Tou had used for a while, or Ownerless Spatial Rings, anyone could access them as long as they had their hands on them.
