Annan knew that advancing to the Gold tier came with risks.

Should one's obsession be exhausted before the advancement is complete, they would become a mindless husk... the so-called "Death Pupa," like a butterfly that never escapes its cocoon.
And the Melvin family had produced a large amount of such "Death Pupae."
