The reason Angel speculates in this way is because the Sky Mechanical City has a history of such actions. Previously, to upgrade the Purification Garden, they sacrificed a large number of apprentices.
Is it the same this time?
Angel thought carefully and felt that it might not be the case.
After all, having apprentices explore the Reincarnation Casket doesn't serve any purpose. Because even if the apprentices discover useful information, can they escape from the Reincarnation Casket?
To escape from the Reincarnation Casket, one must experience at least twenty cycles of reincarnation. In these worlds of reincarnation, ordinary undead gather together, special undead are common, and you might even encounter a fallen deity undead comparable to a legend.
Even a mystic hunter like Frost, who surpasses legends, nearly met his end within the Reincarnation Casket.
For an apprentice to survive and come out? It's almost impossible.
