Near the summit of the Mountain of Hidden Weapons were also vast crystalline regions. The Secret Treasure Pearls within those crystalline regions were even more numerous than those below the mountainside. Mountain-Bearing True Person, Zhang Anguo, and Qi the Old Freak were searching near the summit for Secret Treasure Pearls that might contain storage pearls and spatial equipment.
One of the most important characteristics of Silver Secret Treasures was that they broke through the physical and spatial limits of conventional equipment—limits of size, solidity and intangibility—creating equipment whose principles of existence were already beyond ordinary people's comprehension.
Weapons among Silver Secret Treasures could turn the intangible into the tangible, directly drawing elements from the Elemental Realm and combining them into solid forms. To ordinary people, this was already mythology.
Storage pearls and spatial equipment, on the other hand, could turn the tangible into the intangible, opening up immense capacity and space within equipment of a fixed size.
If knights, having sensed the existence of the Elemental Realm, could still understand the principle behind Silver Secret Treasure weapons turning the intangible into the tangible, then the principles behind things like storage pearls and spatial equipment were beyond the understanding of people of this era.
Were they miniature wormholes? Folded space? Methods of compressing and restoring matter's quantum state of existence in a particular way?
No one knew!
Everything was mere conjecture.
Scientists might have found this fascinating, but to knights of this era, being able to hold something in their hands was what mattered. Everything else was bullshit.
Although spatial equipment such as storage pearls counted as Silver Secret Treasures, they were considerably more advanced than ordinary Silver Secret Treasures. Moreover, unlike ordinary Silver Secret Treasures, storage pearls hidden within Secret Treasure Pearls displayed no true form of a secret treasure
