Card

Biodata

Classification

Appearance

Ordinary Cards are commonly depicted as silver, glowing objects bearing abstract patterns. Their patterns can suggest an identity or trait, but reliable information generally requires digestion or system access 32.

• Abyss Cards may appear blood-red and translucent rather than silver 519.
• Duplicate Cards can exist; one Contaminant precipitated seventeen Cards, including multiple Centipede and Ant Cards 32.
• A Card can crystallize from a corpse after death 475.

Acquisition and Precipitation

• Killing a Xenomorph can cause one or more Cards to precipitate from its corpse 3 32.
• A Xenomorph that logs out abandons its body and does not leave a Card behind 11.
• Inside a Labyrinth, Cards from dead Players or humans may remain if the system fails to reclaim them; Labyrinth creatures can subsequently acquire them 373.
• Labyrinth creatures that acquire unreclaimed Cards may exceed their natural growth limits and become comparable to a Labyrinth Master 373.
• Cards are not indestructible. Explosions, extreme heat, and similar conditions can damage or destroy them before recovery 574.
• Players initially receive a randomly assigned character and main Card when connecting to the system. They may spend Points to reroll an unsatisfactory character or Card 37.
• Humans cannot draw a new main Card through re-registration, though they can still digest Cards they obtain 228.

Digestion and Deck Mechanics

Card Digestion

Digestion integrates a Card into the holder's body and may add, strengthen, alter, or fail to grant abilities depending on compatibility 3 299.

• Killer Bee granted target marking and tracking after digestion 3.
• Repeated Crimson Ghost Centipede digestion expanded Feng Ling's Mother's Embrace into four fang-and-claw limbs while improving hardness and speed 33.
• Not every inherited trait remains intact: Feng Ling lost Ghost Jellyfish's underwater transparency after a later skill conflicted with it 156.
• A Card used as a main Card and the same Card absorbed as a sub-Card can produce different results 299.
• Administrators can view a Card's traits, but cannot necessarily determine exactly how a skill will manifest within a particular deck 540.

Main and Sub-Cards

• The main Card determines a holder's growth ceiling and foundational ability direction 410.
• Digesting compatible sub-Cards may enhance existing skills or unlock new ones 410.
• Incompatible Cards can produce disproportionately high Corruption Value and limited practical benefit 337.
• Once a Card's gene chain fully merges into the body, it can no longer be removed through Card-draw mechanics 408.

Card Influence

Card traits can subtly influence a holder's behavior and personality, though personal will remains a deciding factor 14 162 482.

• The Demon Card is associated with intimidation, mischief, mystery, and provocation 14.
• Research identified Card-induced personality influence as a measurable concern among Card holders 162.

Corruption Value

Digesting Cards increases Corruption Value, with the increase affected by compatibility, Card rank, and the holder's deck 33 519.

• Early research estimated the human tolerance threshold at roughly 22%; four of twenty experimental subjects died after their Corruption Values went out of control 162.
• Most Players keep decks at three Cards or fewer because suitable Cards are scarce and excessive Corruption Value is difficult to reverse 33.
• High-level and Abyss Cards carry especially serious risks when incompatible with the holder's main Card 519 743.
• Excessive Corruption can lead to genetic collapse, mutation, or death 162 544 743.

Card Draw Game

Certain Labyrinth Idols can remove a Card from a holder's deck through a random draw, lowering Corruption Value in exchange for the Card and its buffs 93 409.

• Feng Ling lost Mirror Newt in a draw, losing its Nest Building ability while reducing her Corruption Value to 15% 93.
• Ye Zheng sacrificed Royal Moth through the same process, reducing her Corruption Value to 33% 409.
• The mechanic cannot remove Cards that have fully merged with the holder's body 408.

Advancement

Cards possess individual growth systems. Digesting suitable Cards can advance a holder through forms and unlock new stages of the main Card's potential 333 410.

• High-level Cards have the greatest advancement ceiling but are also the most difficult to evolve safely 333.
• Feng Ling's Hive advanced from Juvenile Form to Mature Form after digesting Queen Mother of the West 128.
• The Hive later reached Completed Form after Feng Ling digested three High-level Cards, triggering a system-wide danger warning 333 337.
• Completed Form does not necessarily prevent further skill acquisition; continued digestion can still add abilities if Corruption Value remains manageable 410.

Storage and Handling

• The Supervision Bureau uses a Card Storage Device: a cylindrical alloy apparatus that emits low-frequency sound to draw a precipitated Card into an internal glass tube 11.
• Qingjiang City initially possessed only one such device 11.
• The Squirrel Card can store Cards and read their information after storage 139 520.
• A phone storage function can hold Cards but cannot release them; stored Cards may therefore have to be surrendered to the Supervisor General Bureau's Research Institute 341.
• Storing Cards in an unstable holder can be dangerous: if the storage Card merges into the holder's genes, the stored Cards may cause secondary contamination 504.
