Naturally, the Scarlet Family was aware of the unique difficulty mechanisms of the labyrinth, so they wouldn't commit the folly of having Cardinal Elder and Obsidian Elder join the Labyrinth Raid Team.
The "method" they mentioned refers to a special way of entering the labyrinth that only they could execute.
This special method revolves around Viviana.
To protect the Divine Heir, Viviana, the Scarlet Family inscribed a concealed magic circle within her at birth.
This magic circle has two activation methods: one is for Viviana to initiate it herself, and the other is for it to automatically trigger when Viviana's life is in danger.
Regardless of the method, once the concealed magic circle is activated, Cardinal and Obsidian Elders would be teleported to Viviana's side immediately to ensure her safety.
This unique teleportation applies even if Viviana is within the labyrinth.
