This is Vault Number Five, one of the seven major secret repositories of Huaxia, storing a large quantity of Spiritual Materials.
As for the other vaults, each focuses on different items: Vault Number Four stores various equipment, Vault Number Three stores Rare Artifacts, and Vault Number Two stores Spiritual Marvels produced in the Wilderness Area.
Vault Number One, while the smallest in scale, has the highest specifications and stores the accumulation of Huaxia's National Destiny Artifacts over the years.
Other countries also have National Destiny-level Artifacts, just not as consistently produced as Huaxia's.
Thanks to Huaxia's relatively stable situation in Spiritual Energy for the past eight hundred years, with no large-scale internal turmoil, these National Destiny-level Artifacts serve as a deterrent, similar to nuclear weapons, and are rarely depleted.
