Angel had made that guess because Sky Mechanical City had a precedent for such things. Back then, in order to upgrade Purification Garden, they had sacrificed a great number of apprentices.
But was this time the same?
Angel thought it over carefully, then felt that perhaps it was not.
After all, there was no point in sending apprentices into the Casket of the Undead's Reincarnation to explore. Even if an apprentice discovered some useful information, could they possibly escape from the Reincarnation Box?
To emerge from the Reincarnation Box, one had to undergo at least twenty reincarnations. In those reincarnation worlds, ordinary undead appeared in swarms, special undead were not uncommon, and one might even encounter fallen god undead comparable to legends.
Even Frost, a mysterious hunter above the legendary realm, had nearly met his downfall in the Reincarnation Box.
Could apprentices come out alive? That was practically impossible.
Since apprentices could not emerge from the Reincarnation Box, they naturally could not convey any useful information.
After rejecting his own conjecture, Angel sank back into confusion... Could his initial guess have been wrong? Perhaps this was not the Reincarnation Box at all?

Sanders already knew of it, so
