Background / History

Green Field City developed from the inherited Sky City of the Green Field Civilization. Six months after arriving in Sky City, Lu Yuan formally established Green Field Town after its residents reclaimed 8,000 mu of farmland and alleviated their food crisis. The settlement later grew into Green Field City through industrialization, education, cultivation, and the use of inherited infrastructure. 620

The city’s continued expansion relied heavily on the legacy of the Green Field Civilization, including Sky City’s anti-gravity regulation, the Opium Tree, and Green Field Paradise. Green Field Paradise’s surviving systems enabled the city to preserve and inherit prior-era knowledge, while the original city structure provided a foundation for habitation, factories, power stations, farms, reservoirs, warehouses, and escape mechanisms. 510 730 826

After three years of preparation, propaganda, and diplomatic arrangements, Green Field City departed the Northern Frontier. Its leadership regarded the long peaceful period there as a potential source of complacency and chose continued exploration over permanent settlement. 67 111

City Layout and Infrastructure

Green Field City has been repeatedly expanded and reconfigured as its population and capabilities grew.

• It has been described as a layered city with ring-shaped zones; the outer ring serves as a military district, while inner rings contain technology, industrial, and education districts. 67
• A later three-layer configuration covered 450 square kilometers: a 200-square-kilometer lower layer for agriculture, military facilities, experiments, Green Field Mountain, Coral Island, and high-risk laboratories; a 150-square-kilometer middle layer for residences and industry; and a 100-square-kilometer upper illumination zone. 812
• Another expansion added a fourth layer whose area alone reached 360 square kilometers, supporting a population of 6.5 million. 555
• The city uses extensive greenery and extraordinary plants. It possessed more than 600 Spirit Plant Fields, while Golden Rainbow Vines provide long-blooming flowers, edible fruit, and fodder. 555
• The central ecological dome contains extraordinary plants maintained under the Harvest Blessing. 67
• The Opium Tree’s stump is protected beneath a large glass greenhouse that admits sunlight while providing defensive value. 202
• Short-Distance Space Web Technology reduced cross-city travel to less than a second, replacing much of the former drone, car, and train traffic. 114
• Tens of thousands of Grotto-heavens in a Pot provide a combined internal space of approximately 3,000 cubic kilometers. 114
• The inner ring is encircled by a 120-kilometer heavy earth-attribute wall with defensive and load-bearing capabilities, including access for cargo trucks. 10

Flight System

Sky City uses anti-gravity technology inherited from the Green Field Civilization. Its gravity must remain partially reduced after landing because ordinary ground cannot safely bear the city’s full mass. 730

• During an early flight test, Sky City stabilized at an altitude of 20,000 meters and traveled at approximately 0.09 kilometers per hour. 730
• Its power system has drawn on human-generated electricity and wind power during sandstorms. 730
• City-wide flight and gravity regulation were originally handled through Green Field Paradise, making the inheritance system strategically essential. 730

Green Field Paradise

Green Field Paradise is the surviving virtual-world and inheritance system associated with the Green Field Civilization. Its artificial intelligence identifies itself as Green Elf. 510

• Its six documented modules are:
  • Carefree Paradise
  • Green Field Heart
  • Industrial Paradise
  • Education Paradise
  • Battle Paradise
  • Technology Paradise 510
• Carefree Paradise formerly carried the consciousness of hundreds of millions of Green Field People, but was destroyed during the prior civilization’s war. 510
• Green Field Heart serves as the central management backend for the system. 510
• The Green Field Civilization Inheritance System was designed to transfer top authority to surviving Green Field People if the original administrators perished. Seashell activated the system through her verified bloodline and soul identifiers. 510

Economy and Trade

Green Field Trading Market

The Green Field Trading Market was established to turn the city’s industrial output, security, and reputation into a regional trading platform.

• Its first phase covered roughly 22 square kilometers and included 360 large buildings, more than 1,000 residential buildings, botanical gardens, animal-breeding bases, restaurants, supermarkets, and hot-spring resorts. 52
• Green Field City recruited foreign races for service industries because its own workforce was more valuable in technical and industrial roles. 52
• By the second year, 51 foreign cities had settled in the market and its permanent foreign population had reached 66,000. 52
• A later market configuration covered approximately 60 square kilometers and hosted at least 300,000 beings of different races. 485
• Civilizations receive a free 100-square-meter exhibition hall; larger spaces require payment for construction. 393
• The market purchases Civilization Points at a stated rate of 1 Civilization Point for 50 Spirit Essence, while emphasizing open and fair trade. 393 515
• Green Field City’s sale of Spirit Plant Fields created demand from nearly a thousand competing cities, forcing the market to use a lottery system for purchase priority. 613

Field Industrialization

Field Industrialization is one of Green Field City’s defining economic and technological strengths.

• The city developed a stable method for producing Spirit Plant Fields, derived from Plant Affinity and Extraordinary Tinder principles. 52
• It later created the Focus Field, which increases concentration and helps Artisans accumulate Inspiration. 662
• Other documented Fields include the Body Settling Field, Detection Field, Shelter Field, and custom Fields for Great Grandmasters. 662 798
• The Shelter Field was placed in the Trading Market’s central square as a public display of the city’s capabilities and prestige. 798
• Artisan University was founded with Li Datie as its first president, supported by an Education Committee of six Artisan Masters. 798

Defense and Expeditionary Forces

Green Field City avoids unnecessary war because of its comparatively limited population, but maintains substantial defenses and deterrent forces. 493

• The city maintains dedicated military and external exchange zones; the latter allows it to receive foreign visitors without exposing Sky City’s core secrets. 202
• King Insects serve as elite insect-hive warriors. They are Level Twelve extraordinary lifeforms and stand roughly four meters tall in golden armor. 48
• One King Insect recorded a combat power of 170,000, a level considered capable of overwhelming ordinary Powered Armor forces. 162
• During a Level Guai incident, Green Field City deployed 98 Giant God Soldiers armed with high-energy particle cannons, magnetic rail sniper cannons, and heavy armor-piercing rounds. 142
• Its arsenal includes high-power Blood Guai Bullets, Aberration Bullets, a restraint cage purchased from the Turtle Civilization, and access to the Ancient Worm Horn Cannon. 142
• The Green Field Knight serves as the city’s ceremonial spaceship and is equipped with detectors capable of identifying high-level supernatural fluctuations. 265
