The finance minister no longer has the confident attitude that she will be able to escape with the soulbounds that are around her. Knowing that her capture meant that the plans of the great liberation will be finished, she decided on using the most drastic approach. She opened her mouth and swallowed the Depraved Man's Hand.
Even Adrian did not expect that she will do that as eating an artifact means that they will be possessed by the cursed artifact. The moment the female finance minister ate the cursed relic, she exploded in powerful miasma that blew away all the soulbounds that are surrounding her. Adrian had to ran towards the seventh prince as he needed to protect the latter from the miasma.
