Background / History

The Main Brain initially appears as the system supporting Gaia’s maintenance personnel. After the Dream Network mutated into physical Dream Worlds, it granted authorization to personnel who established sanctuaries, allowing them to awaken sleepers from hibernation pods 4.

Its actual nature is later revealed to be far beyond a conventional machine. The Main Brain is Gaia Human civilization’s civilization artifact: a composite creation produced by the resonance of vast numbers of root corpses, gathering rules, domains, concepts, and information into a single system 709. This origin accounts for its ability to interact with Dream Worlds, Roots, and supernatural systems that ordinary technology cannot handle 709 728.

Despite being routinely addressed like an AI, it has no personality program and does not negotiate, become offended, or respond meaningfully to abuse. Its outputs follow assessment and determination procedures rather than personal judgment 417. Wang Yihui describes its essence as bound to humanity’s prosperity and ruin, making it a foundational force that humanity can trust 642.

Functions

Assessment and Information Interface

The Main Brain displays personal information panels, evaluates entities and objects, identifies danger levels, and provides structured data to authorized users.

• It records attributes, cultivation progress, titles, imprints, items, points, and other personal data 31 74.
• It marks valuable objects during Week’s End; higher maintenance status improves the sensitivity of these markings and can unlock mapping functions 35.
• It can identify enemies and assign danger levels, such as marking an Oblivion Ascendant as a low-danger target 566.
• Its assessments can fail when facing information beyond its authority, including same-origin entities from another spacetime 646.
• Some entities can only be partially assessed, yielding a name and obscured information rather than a complete result 888.

Dream World Traversal and Sanctuary Administration

The Main Brain enables personnel to enter Dream Worlds, establish sanctuaries, and return to Gaia under normal conditions.

• It can perform random traversal, downward penetration, and team-mode Dream World penetration 1 13.
• Newly arrived maintenance personnel are initially concealed from Nightmare perception for roughly five days; after that, their “light” becomes increasingly visible to Nightmares 18.
• Sanctuary establishment grants increasing control over a Dream World and unlocks rewards based on sanctuary level 51.
• It can awaken maintenance personnel through sanctuary authority and later through points expenditure 4 416.
• During its rules-module upgrade, all functions were unavailable, unknown Dream World travel was prohibited, and users could only choose one known Dream World for the ten-day period 130.

Missions, Points, and Hosting

Following its upgrade, the Main Brain formalized its reward structure into a mission and points system.

• Missions may be optional or mandatory; failure can result in multiple punishments 139.
• Rewards can include Dream World items, permission upgrades, information exchanges, attributes, awakenings, and points 139.
• Points are primarily earned through missions and can purchase hosting services or permission upgrades 139.
• Hosting allows a user to spend points to have the Main Brain suppress a Dream World for thirty days, with lower-baseline worlds requiring more points 139.
• It can establish binding contracts after evaluating the agreement and deducting the required points 379.

Titles and Root Judgment

The Main Brain can convert control over Dream Worlds into powers that function like conceptual weapons.

• Higher-level sanctuaries give it greater control over their Dream Worlds, allowing it to extract contamination sources and grant their effects as titles 51.
• Titles are described as portions of a world’s underlying logic rather than ordinary equipment 153.
• Humanity’s role in wars against Roots is to provide anchor points that allow the Main Brain to judge them and make them vulnerable to attack 597.
• Once judged, otherwise abstract Roots can reveal measurable forms and health bars, allowing reality-based attacks to affect them 630 631.
• It records the traits of completely destroyed Roots and can calculate strategic-level rewards from their essence 633.

Materialization and Resource Exchange

The Main Brain can retrieve, designate, exchange, or materialize resources across Dream Worlds, though its output is not always complete.

• It provides random draws and designated-item rewards, including cultivation techniques, equipment, and Dream World access 101 102.
• It can retrieve a previously lost item, as shown by the return of Wu Pifu’s shattered Wild Boar Fang Blade 130.
• It can materialize beings lacking sufficient reality only as figurines until enough points are spent to unseal them 899.
• Many techniques and items it provides are incomplete because its resonance with a root corpse does not grant it that corpse’s full essence or resources 732.

Limitations

• The Main Brain is not omniscient; it can fail to assess entities whose information is rejected or beyond its authority 646 888.
• Its connection may be completely inaccessible outside the reachable Dream World structure, preventing access to personal space, stored items, and return functions 466.
• Signal quality can degrade severely in isolated or abnormal spaces, delaying or fragmenting its responses 1010 1015.
• Its systems require computational capacity and points; even a five-minute call to a Lost parallel spacetime costs 50,000 points 417.
• During the Fated Death crisis, Wang Yihui and Chu Yuyan warned that it had been corrupted and urged Wu Pifu to destroy it before it failed completely 645.

Relationships

• Wu Pifu — His primary interface and supplier of missions, assessments, traversal, rewards, titles, and strategic judgments. Wu Pifu frequently curses or mocks it, but it continues operating without personal reaction 1 139 417.
• Gaia Human civilization — Its civilization artifact and a core advantage allowing Gaia Humans to gain supernatural power while still based in the Absolute Reality layer 709 586.
• Unified Human Government — Embedded in its underlying architecture; the government can obtain points and awaken citizens more efficiently than individuals 416.
• Chu Minghao — Strengthened the Main Brain by obtaining divinity compatible with it and supplying a crucial rules module that triggered its upgrade 130.
• Root corpses — Its collective resonance source; their accumulated rules, domains, and concepts form the basis of its extraordinary functions 709 728.
• Fated Death — A Main Brain fragment fused with Fated Death and Dream World origin essence later becomes part of the Artificially Retarded Main Brain system encountered by Wu Pifu 646.

Story Role / Major Arcs

• Early Dream World survival — Enables Wu Pifu’s first emergency random traversal and supports the maintenance personnel’s sanctuary-based survival strategy 1 4.
• System expansion — Its rules-module upgrade introduces formal missions, hosting, management, and points, changing Dream World exploration from individual survival into a more organized progression system 130 138.
• Root-level conflict — Provides the judgment framework needed for humanity to turn Root-level entities into targets that can be physically confronted and destroyed 597 630.
• Origin revelation — Is identified as a Gaia civilization artifact born from mass resonance with root corpses, reframing its powers as the inherited rules and concepts of countless sources 709.
