In the game, teleportation tools for cross-zone travel are commonly instruments, such as the large teleportation device seen at Granny Bai's zone and the Xin Family in Eye of Platinum. Compared to "Inversion Ring," these instruments are massive, have limited uses, and are definitively expensive and consumable. Whether due to technical limitations or deliberate technological blockage, the frequent cross-zone tools in the game are instruments.
Although Super Props also have usage limitations, they can be used multiple times and are easy to carry.
However, despite being a Super Prop, the "Inversion Ring" cannot be activated outside the game. The "Small Inversion Ring" also cannot be used at the entrance and exit of District 001. To free the people of District 001, they must at least enter spaces like the Metal City or Metal Forest, and then be taken out by the "Inversion Ring." Since the Super Dungeon venue itself is not open, it cannot limit zone teleportation.
