Wristband

Biodata

Power Progression

Appearance & Interface

• Physical form: Initially a simple, dark-colored band worn around Lu Heng’s wrist; later descriptions identify its surface as metal 1 260.
• Display: Produces light screens, floating text, and scanning beams. Ordinary interactions commonly use pale blue light, while its initial binding emits white light 1 37 114.
• Controls: Responds to touch, fingertip taps, and mental activation 1 33 37.
• Alerts: Uses vibrations and warning buzzes as well as visual notifications. Mandatory announcements can appear directly before the user’s vision without a skip option 41 283.

Functions

Environmental & Personal Monitoring

Tracks external conditions and displays information about its wearer and their equipment.

• Environment: Reports the current environment and temperature, including readings of −33°C and −40°C during the blizzards 1 81 84.
• Physical condition: Lists injuries, frostbite, physical exhaustion, mental fatigue, and armor wear 41.
• Attributes and talents: Displays physical attributes and newly acquired abilities, including Temperature Control and Water-Covering Vine Binding 49 69 205 275.
• Parasite detection: Reveals Lu Heng’s otherwise hidden infection through the status [Being Parasitized], then updates it to [Being Parasitized (Suppressed)] after contact with a Snow Pearl 99 100.
• Shelter feedback: Displays low-energy warnings, completed upgrades, and equipment set bonuses 35 136 248.

Appraisal & Knowledge Records

Scans creatures, plants, materials, equipment, and special items, returning information such as names, tiers, effects, and usage restrictions.

• Food identification: Distinguishes edible plants from poisonous lookalikes and reports freshness, contamination, and preparation requirements 35 37.
• Threat assessment: Identifies monster ranks, behaviors, and attack methods, including the Swamp Giant Python’s vibration-based detection and the insect swarm’s specialized units 120 311.
• Material records: Unlocks explanations for newly obtained resources, such as bronze’s inherent Spirit-Breaking property 34.
• Database growth: Creature entries can be recorded through kills or contact; the Swamp Poison Lizard’s entry arrives only after the encounter has ended 13 22.
• Physical backup: A study module can synchronize its Bestiaries, documents, and intelligence into physical books 127.

Appraisal is not exhaustive:

• The Spider Marrow Crystal initially appears only as an unknown material, without an explanation of its use 35.
• The future Purifying Water Lotus is recognizable as an aquatic seed, but becomes [Unknown object] after sprouting 111 112.
• Some construction scrap cannot be appraised at all 209.
• Powerful or unusual targets may receive minimal descriptions: Blood Taisui initially returns only its name and Silver Tier (advancing) status 300.

Storage Space

Provides portable inventory slots for food, tools, materials, equipment, carcasses, and unopened treasure chests.

• Inventory access: Stored items can be retrieved through the interface or by thought 16 222.
• Large objects: Accommodates a workbench, treasure chests, and an intact Black-Eyed Bear carcass 17 34 111.
• Organization: Includes material and miscellaneous-goods categories; later loot intake automatically sorts, merges, and stores supplies 34 35 394.
• Field use: Allows Lu Heng to stow bulky equipment rather than carry it openly, reducing encumbrance and exposure 99.
• Capacity limit: Early storage slots are scarce. Even after expansion, Lu Heng uses stationary storage to reserve portable space for combat supplies 16 17 148.
• Collection restriction: Stones still pinned in hardened riverbed silt cannot be stored until they are dug out 17.

The Clear Spirit Water-Pattern Necklace’s ten-slot inventory is explicitly separate from the Wristband’s main storage 38.

Dismantling & Resource Collection

Breaks down bodies and certain objects into standardized resources.

• Corpse processing: Converts beasts into usable meat, bones, hides, sinews, and other materials, transferring the results into storage 86 113.
• Material cards: Early Cold Stiff dismantling produces physical resource cards. Crushing these cards records them into the system and stores their materials or unlocks permissions 16.
• Batch processing: Can cover multiple Zombie corpses within several meters with a dismantling halo 260.
• Chest reclamation: An empty Black Iron Chest yields five units of black iron without material loss; an empty bronze chest similarly yields five units of bronze 17 34.
• Kill confirmation: Confirms the Blood Banyan Tree’s death after Lu Heng cuts through its remaining moving roots and tendrils 264.

Important limitations:

• Scattered Giant Plume Eagle feathers cannot be dismantled in bulk and must be collected by hand 86.
• Dismantling leaves energy traces that another Blizzard Monster notices at the site where its mate and cub died 95.
• After manually finding both Energy Cores and Flesh Cores inside river beasts, Lu Heng concludes that one-click dismantling has destroyed valuable cores 288. Earlier dismantling of Blizzard Monsters does produce Energy Cores 94.

Crafting & Shelter Management

Connects stored resources, blueprints, workstations, and building modules.

• Forging: Blueprint-based weapon production requires a workbench; the Wristband cannot synthesize the Bone Dagger directly without one 16.
• Automated processing: With a workbench available, its light grinds, shapes, polishes, and sharpens leopard bones into a replacement dagger 50.
• Shelter upgrades: Displays construction requirements and stored materials through an upgrade panel 18 50.
• Module installation: Installs a water purification device directly at the Shelter’s water inlet 38.
• Material requirements: Refuses to activate the ice cellar module until the necessary ice-attribute ore is supplied 38.
• Automatic assembly: Deducts materials from storage and assembles a complete lookout tower within seconds 189.

Communication, Trading & Donations

Supports public channels, private messages, and system-mediated supply transfers.

• Public channels: Provides global and regional survivor discussions, including reports about disasters and resource shortages 69 86 97.
• Private messaging: Allows direct consultation and the exchange of videos, annotated screenshots, and written instructions 114 115.
• Identity display: Automatically shows survivors’ real names rather than nicknames or identification numbers 290.
• Trading: Uses a verification window to exchange supplies after both parties confirm the terms 135.
• Donations: Transfers donated supplies under system management, without human handling. Lu Heng confirms a donation through the Wristband, and the selected meat is removed from his cellar 109 136.

Surveillance & System Access

Connects the wearer to security equipment, territorial restrictions, and compulsory world-system notices.

• Security links: Binds a Silk-Peeping Bug to the Shelter’s power supply 53.
• Lookout alerts: A linked lookout tower sends Wristband alerts for approaching creatures or moving objects within twenty meters of the Shelter and can share Spy Bug surveillance views 189.
• Mandatory broadcasts: Global disaster announcements cannot be blocked or skipped 190.
• Travel rules: Communicates the five-percent supply charge for travel between the original and newly opened regions 198.
• Territorial permissions: Outside survivors receive [No permission to enter.] when reaching Moonview Valley’s restricted entrance 370.
• Encrypted records: Stores Greedy Wolf awakening information in a deeply encrypted access level without Lu Heng initially noticing. He later deliberately opens the concealed awakening assessment 304 309.
