Power Progression

Stage / Realm / Level	Chapter	Notes
Level one	234	Documented baseline. Ion Beam Weapons are mastered, opening the path toward level-two Plasma Weapons; Lü Yongchang finds no usable defensive technology in the level-one tree.
Level two	307	The level-two technology tree is accessible. Optical quantum computing and Nanometer Robot Technology connect to Starship Adaptive Repair Technology; the Ternary Computer appears as a future research node.
Consolidated level two	315 317	Sixty years of development produce carbyne-strengthened ships, the Ternary Optical Quantum Computer, Plasma Weapons, and a fleet of 3,000 starships. Ship cruising speed reaches 0.2c.
Level three	428 430	Research into magnetic-field shields, supported by dismantling a Lator secondary flagship, culminates in basic shield technology, the defining foundation of level three.
Level four	516 517 547 583	The Antimatter Engine opens the level-four tree. Antimatter production strengthens propulsion and weapons, although Warp Drive and Gravity Manipulation Device research initially remain incomplete.
Level five	659	Completion of grand unified theory brings advancement in Earth Calendar year 3276. By 3300, humanity has successful crewed curvature navigation, stronger gravity shields, and warp weapons.
Peak level five	742	By Earth Calendar year 3700, maximum travel speed reaches 100c. Practical control of fundamental forces supports black hole missiles, Gravity Bombs, and Matter Disintegration Cannons.
Level six	818	Confirmed during the three-century development period ending in Earth Calendar year 4050. Four-Dimensional Optical Brain research accelerates spacetime theory, grand unified field theory, and spatial weapons.
Peak level six	819 822	Star-class starships complete the transition. Mainline warships average 80,000 meters, while the flagship Earth reaches 200,000 meters; curvature performance approaches 1000c.
Quasi-level seven	838	Research into natural Klein bottles and the micro-universe advances higher-dimensional spacetime theory, taking humanity into the domain of level-seven technology.
Level seven	889	The foundational level-seven node illuminates and the technology tree advances. Subsequent development enables large-warship jumps and white dwarf-class construction.
Quasi-level eight	911	Lü Yongchang reveals that humanity has risen from level one to quasi-level eight in just over ten thousand years, sharing key vacuum zero-point energy theories with the Saikol Civilization.
Level eight	917 922	Successful operation of Suirenshi establishes preliminary mastery of vacuum zero-point energy. The later account places this advancement 170 years before Earth Calendar year 14370.
Level eight with dimensional ascension	934 937 950	Humanity gains attacks through the fourth spatial direction and defeats pursuing four-dimensional beings. Biological adaptation remains a serious obstacle to prolonged ascension.
Level nine	978	Completion of source theory identifies zero-dimensional singularities as the universe’s basic units and formally crosses the level-nine threshold.
Consolidating level nine	980 983	A successful five-dimensional voyage by Flood Dragon prompts production-line upgrades for black hole-class starships. Humanity contests the manipulation of physical laws through Genesis.

History

Solar Catastrophe and Exodus

In the original doomed future, humanity shelters underground before the Sun’s helium flash engulfs Earth. Lü Yongchang witnesses the catastrophe with Su Yutong, then awakens in a university classroom in 2030 with knowledge supplied by a mysterious technology tree. He resolves to prevent humanity’s extinction 1.

In the changed course of events, humanity evacuates Earth aboard an interstellar fleet. The final evacuees ascend through the Jianmu Space Elevator while catastrophic weather destroys the surface. Fifty Luan Bird Type I Starships carry five hundred million people in hibernation, and Lü Yongchang departs aboard the flagship Earth 192.

Proxima Centauri and Reconstruction

The Human Fleet reaches the outskirts of Proxima Centauri on Earth Calendar date 2146.6.7 after traveling 4.22 light-years. Its final approach uses inertial coasting, with thrusters and high-power radio facilities shut down to conceal its movements 263.

During the war, humanity blockades Proxima b and decodes the Proxima Centauri people’s genome to develop a weapon intended to secure victory without a direct fleet battle. The later account states that humanity chose genocide to save time and eliminate future threats, leaving no prisoners 284 375.

Over sixty years of reconstruction, humanity builds twenty cities on Proxima b and rebounds to a population of six billion. Materials, computing, propulsion, and weapons improve, but the deaths of numerous elderly researchers leave Lü Yongchang mourning the people who made that recovery possible 315.

Advanced Civilizations and Apparent Extinction

Contact with the level-seven two-dimensional lifeform Hua introduces humanity to the Cleaners, Gardener Faction, and Neutral Faction. Lü Yongchang negotiates for a simplified Two-Dimensional Fragment Stabilizer, but Hua declares that the request has cost humanity its opportunity to join the Gardener Faction 330 332 345.

Humanity defeats the Lator fleet and confronts the problem of handling alien prisoners for the first time. The resulting debate becomes a broader discussion of humanity’s future relations with other civilizations 372 375.

After conflict with a Cleaners probe and the Bosa Civilization, both the Gardener Faction and Cleaners conclude that humanity has been destroyed by a chain reaction involving Hua’s fragments. Sweeper 9527 identifies human remains within a two-dimensional painting, reports humanity’s extinction, and cancels its warrant. Humanity nevertheless appears in later chapters as an active civilization 568 583 624.

New Humans and Kepler-452

Humanity’s social public child-rearing system produces a generation whose outlook increasingly centers on civilization rather than blood-related families. Lü Yongchang regards this as a profound transformation forced by humanity’s circumstances, while recognizing that education must sustain the new outlook over a long period 613.

Contact with the Lost Giant Trees reveals Nus, their collective consciousness. Exchanges with the surviving Nus Civilization subsequently contribute to humanity’s biological research and lifespan-extension technology 627 660 818.

At Kepler-452, humanity deploys Dyson Clouds, expands its specialized fleets, terraforms planets, and builds a surrounding network of probes and space gun emplacements. Following Kepler-452b’s transformation, the Awakening Ceremony commemorates the dead, declares the age of catastrophe over, and begins awakening the billions still in cryosleep 666 713.

Federation Expansion and Voluntary Expedition

The Pan-Human Federation expands through diplomacy, military coercion, and vassal agreements. By Earth Calendar year 3700 its territory spans five hundred light-years; over the following centuries, it reaches 1,000 light-years and includes more than a thousand vassal civilizations 742 818.

After obtaining star-class ships, humanity approves an expedition beyond the Milky Way. Unlike its earlier migrations, this voyage is undertaken voluntarily rather than as an escape. By Earth Calendar year 4400, expedition preparations have expanded its territory to 1,800 light-years despite deliberate limits on further growth 822 824 825.

The expedition retraces parts of humanity’s old escape route before reaching Andromeda. There, humanity fights the Cleaners, reactivates the Dandelion Plan to spread its seeds toward nearby galaxies, and eventually relocates into a micro-universe before setting out toward M87 with the Silicon Stingray Civilization 846 864 867 893.

M87 and the Boötes Conflict

The Gardener Faction exposes humanity’s Enroget identity near M87. Lü Yongchang openly acknowledges humanity’s past, demonstrates its exceptional development rate, and secures the Saikol Civilization’s protection. The Tenth Empire later broadcasts that Silicon-Based Alliance members must shelter humanity 911 916.

After achieving level eight and mature wormhole technology, humanity leaves the Virgo Cluster. It reaches the Shapley Supercluster by Earth Calendar year 15500 and uses its galaxies as stepping stones toward the Boötes Void 917 923.

Humanity’s dimensional research and rapid growth provoke an all-out Gardener campaign. It captures Thread and Ant, defeats pursuing four-dimensional beings, and obtains intervention from the Tenth Empire and Neutral Faction. Accusations that its central computer contains prohibited advanced artificial intelligence subsequently bring the Cleaners and Gardener Faction together against it 950 953 966 967.

Total War and Restoration

Rejecting demands to open its Civilization Central Computer, humanity attacks first. The Tenth Empire and Neutral Faction join its side, while humanity’s industrial output allows its fleet to grow despite enormous combat losses 968 969.

After devastating losses, the Cleaners’ intervention draws the Gardener Faction’s attention away long enough for humanity to rebuild. Eighty-one years of uninterrupted manufacturing raise the Human Fleet above thirty billion ships. Humanity later completes source theory, reaches level nine, and sends a seventy-billion-ship fleet against Membrane 975 978 982.

The final battle pits humanity against Membrane and a Cleaners fleet equipped with shared law-manipulation technology. The subsequent account confirms the destruction of the Cleaners’ main fleet and humanity’s eradication of its remaining forces. Lü Yongchang then orders the repair of the devastated Laniakea Supercluster, which Zero restores over more than three hundred years 983 984.

Government and Society

Institutions

• Chief Scientist — Lü Yongchang directs scientific development and major strategic decisions. His leadership acquires extraordinary prestige over centuries; by the expedition era, 99.99% of the Federation’s thirty billion citizens have grown up hearing accounts of his deeds 375 824.
• Human Federation Parliament — Participates in policy discussions and unanimously approves the intergalactic expedition alongside the Academy of Sciences 375 824.
• Academy of Sciences — Coordinates research, ship development, biological studies, and technological exchanges with other civilizations 666 818.
• School of Sociology — Develops vassal-risk assessments, evaluates alien societies, and trains foreign-affairs personnel 666 695 698.
• Ministry of Foreign Affairs — Recruits Lin Shuguang following his assessment of how humanity should treat hostile and useful alien civilizations 666.
• Zero — Manages computation, automated industry, fleet coordination, and vassal computer systems; also assesses eligibility for contribution-based lifespan extensions 315 698 818.

Child-Rearing, Lifespan, and Culture

• Communal upbringing: The social public child-rearing system encourages New Humans to regard all humanity as one large family, placing civilization-wide development above narrow family interests 613.
• Lessons from failure: The separate Proxima Centauri human civilization supplies eighty years of child-rearing-system data after its reforms fail. Its suffering informs the Human Federation’s own decisions 421 428 496.
• Lifespan extension: Research derived from the Nus Civilization establishes a baseline lifespan of about a thousand years. Additional extensions depend on contributions assessed by Zero 818.
• Cultural influence: Human history and everyday culture spread rapidly among the Talodans, inspiring reverence for humanity and Lü Yongchang 703.
• Art: Art has little priority during the escape era, but begins to flourish again as humanity grows stronger and interacts with vassal cultures 907.

Documented Population and Territorial Milestones

Milestone	Documented Scale

Foreign Policy and Vassal System

Membership and Obligations

• Stated purpose: An interstellar alliance based on mutual benefit, mutual support, and shared progress; vassals are explicitly distinguished from slaves 693.
• Autonomy: Vassals are promised relatively extensive freedom to preserve their existing way of life 693.
• Trade: Contributions earn Credit Points exchangeable for advanced equipment, weapons, selected blueprints, and even level-five warships 693.
• Security: Humanity promises protection to accepted members and warns the Eugene Civilization that attacks on the Talodans will be treated accordingly 698 700.
• Admission review: Joining the Pan-Human Federation requires a comprehensive assessment; surrender alone does not guarantee membership 720.
• Computer control: The Talodan agreement gives humanity access to the fleet’s Central Computer. Trojan 1.0 obtains control, after which Zero assumes computation and management duties 698.
• Coercive expansion: Membership is not always voluntary. Military demonstrations, defeated fleets, and pressure from the Eugene Civilization help bring other civilizations into the Federation 742 783.

Vassal Risk Assessment

The School of Sociology’s model evaluates threats on a hundred-point scale using internal civilization data. A score can rise suddenly following particular actions 698.

Risk Value	Response
Below 30	Regarded as model Federation members 698
30–50	Gentle measures to reduce risk 698
50–70	Coercive measures 698
Above 70	Zero locks down computing equipment; the Human Federation fleet moves to eliminate the potential threat 698
Talodan assessment: 5	Considered an exceptionally low-risk vassal 698

Technology and Military Capabilities

Technology Tree and Scientific Development

Humanity’s central advantage is Lü Yongchang’s access to the Technology Tree System, combined with Zero’s expanding computational capacity 1 315 818.

• Supplies research directions and technical knowledge, including controlled nuclear fusion and carbyne synthesis 1 315.
• Connects advances across disciplines: optical quantum computing and nanorobotics support adaptive repairs, while higher-dimensional computing accelerates spacetime and field theories 307 818.
• Allows some technologies to precede their usual level: humanity partially constructs its Dyson Cloud and Dyson Ring system before recognizing them as level-four prerequisites 516.
• Does not remove research hazards. Thought Imprint and Four-Dimensional Optical Brain technologies are identified as incomplete higher-level technologies with significant risks 818.
• Sustains an unusually accelerating development rate instead of the slowdown normally seen as civilizations advance 742 950.

Automated Industry and Fleet Coordination

Zero directs factories, repairs, drones, and large-scale military production 315 659 969.

• Drone swarms become a principal fighting force, provided communications remain intact 315.
• Engineering Ships can join into temporary Starship Factories, producing ammunition with materials supplied by Glutton reserve ships 757.
• Automated construction processes stars and planets into industrial materials on an assembly-line scale 922.
• Manufacturing allows fleet growth to outpace wartime losses: after losing over a hundred million ships, humanity nevertheless expands to a billion-ship fleet 969.
• Computing remains a bottleneck. Expanding fleets and factories consume more of Zero’s capacity, and the final contest against two law-manipulating level-nine opponents pushes utilization to 100% 969 983.

Propulsion and Dimensional Travel

Development	Capability and Limitation
Improved Hall Thrusters and fusion reactors	Ships reach 0.2c and probes 0.25c after the sixty-year Proxima reconstruction 315.
Early level-five curvature navigation	Theoretical maximum reaches 50c, but most travel remains below 10c because of communication failure, energy consumption, and resource limits 659.
Peak level-five curvature navigation	Maximum speed reaches 100c 742.
Peak level-six curvature navigation	Updated warships exceed 900c and approach 1000c 819.
Four-Dimensional Leap	Initially enables small kinetic weapons to bypass shields and armor; later supports large-warship jumps exceeding one hundred million kilometers 859 890.
Mature wormholes	Enable travel across hundreds of millions of light-years; galactic matter remains necessary for efficient long-distance voyages despite vacuum zero-point energy 923.
Dimensional ascension	Permits observation and attack through the fourth spatial direction, but most humans cannot adapt to prolonged four-dimensional life 934 937.
Five-dimensional travel	The successful voyage of Flood Dragon supports the transition toward new level-nine fleet technology 980.

Defenses

• Starship Adaptive Repair: Nanorobots continually restore damaged hulls; early ships combine repair with rotation and evasive movement against lasers 307 362.
• Magnetic-field shields: Establish humanity’s level-three foundation. Later regional deployment protects selected areas without burdening a full-ship shield 430 548.
• Gravity shields: Strengthened by gravitational-field-control breakthroughs following grand unified theory 659.
• Combined fleet shield: Spreads defensive loads across multiple Shield Generators. An Enrojet estimate suggests roughly fifty thousand attacking warships would be needed to break it under the observed conditions 758.
• Radiation Shielding Layer: Supplied through Nus-related technology, but insufficient to withstand humanity’s own Twin Starburst attack 870.
• Spatial compression: Shrinks later ships externally while increasing internal space and combat capacity 922.

Weapons

• Electromagnetic and energy weapons: Progress from electromagnetic cannons and Ion Beam Weapons to plasma cannons, advanced lasers, gamma-ray weapons, and Matter Disintegration Cannons 234 315 516 742.
• Genetic weapon research: Decoding the Proxima Centauri genome allows humanity to design a weapon intended to defeat the enemy without direct fleet combat 284.
• Antimatter weapons: Improve destructive power and missile propulsion; early estimates place two direct High-Yield Antimatter Missile hits as sufficient to destroy the asteroid-class Earth 517.
• Two-Dimensional Fragments: Used offensively against Bosa ships, though the reported strike fails to damage the Bosa flagship 568.
• Black hole missiles and Gravity Bombs: Attack through concentrated gravity, tidal forces, and gravitational fluctuations 742 764.
• Spacetime resonance: More than two thousand coordinated warships generate a spacetime tsunami, disrupting an enemy Spatial Weapon and degrading interception accuracy 778.
• Spacetime Traps and Spatial Rifts: Cripple level-five fleets during humanity’s level-six expansion; later Spatial Rifts last over an hour and travel at up to 1000c 818 819.
• Twin Starburst: Collides two comparable stars and triggers their cores to produce a supernova-scale explosion capable of destroying an entire stellar system. Its danger to friendly forces prevents early testing 870.
• Dark Matter Bombs and dimensional attacks: Help split Thread apart, while four-dimensional attacks can bypass defenses confined to three dimensions 934 941.
• Genesis: Manipulates physical laws within a human-made quasi-universe bubble; later assists in reconstructing regions reduced to fundamental particles 983 984.

Fleet and Major Assets

Starship Development

Era	Documented Fleet or Ship Specifications
Earth evacuation	Fifty Luan Bird Type I Starships, with Earth serving as the departure flagship 192
Level-two reconstruction	3,000 starships; Earth measures 5,000 meters, ten secondary flagships measure 3,000 meters each, and ordinary ships range from 500 to 1,500 meters 317
Early antimatter era	Existing asteroid-class ships are upgraded while satellite-class development waits on propulsion and gravity research 517
