Red Key

Red Key is notable because it serves the following role: a final-arc artifact used against the Cursed Hospital director's altar and concealed heart. Its importance comes from demonstrated use and custody rather than an assumed artifact rank.

History

The blood-red key appears during the final assault on the Cursed Hospital. A red-clothed ally linked to Chen Xiang’s side uses it against the director’s altar, where the enemy’s concealed heart and control structure are protected. (Chapter 1204)

Abilities and properties

• Pierces, destroys, or unlocks the hospital altar during the Demon God battle. (Chapter 1204)
• Its effect is powerful enough to matter against a structure protected by the hospital director.
• The text does not establish a reusable lock-opening power, independent intelligence, or a formal artifact class beyond the demonstrated attack.

Ownership and custody

The key is carried into the final battle by the allied red-clothed force and used immediately on the altar. Its origin and later physical custody are not established clearly enough to assign a permanent owner. (Chapter 1204)
