Background / History

The empire is identified by Huo Yuhao as the “meta answer” for an era of divided states and continual warfare, with continental unification presented as more beneficial than endless conflict among separate countries 9.

Huo Yuhao entered the empire after fleeing the Star Luo Empire. Xiao Hongchen and Meng Hongchen recognized his potential at the border and sought to recruit him into the Sun Moon Imperial Soul Engineer Academy 16. His later inventions, cultivation, and cooperation with figures such as Kong Deming, Jing Hongchen, Xu Tianran, and Gu Yuena became central to the empire’s rise.

The old emperor initially intended to retain the throne until Huo Yuhao and the empire’s strongest younger generation had matured, then pass it to Crown Prince Xu Tianran to pursue unification 173. Xu Tianran ultimately ascended the throne after the empire had seized and begun reorganizing former Star Luo and Heaven Spirit territories 319.

Government and Society

• Emperor — The former emperor resumed direct control of state affairs after Xu Tianzhen healed him with a piece of Gold of Life 49 83.
• Emperor Xu Tianran — Succeeded the old emperor and led the postwar reorganization of conquered territories without favoring the original Sun Moon regions 319.
• Kong Deming — Grand Elder, Huo Yuhao’s teacher, and a leading Soul Tool Master; personally executed Titan at the war’s conclusion 49 336.
• Jing Hongchen — Major Soul Tool authority who later became a Super Douluo and helped defend Mingdu 217 242.
• City Management Team — Maintains order in Mingdu during the Soul Master Competition; backed by Rank Nine Soul Engineers and defected sect personnel 216.

The empire’s policies emphasize ordinary people’s welfare alongside military development. Free awakening ceremonies and barrier-free Soul Tools were implemented for commoners, while immigrants from other nations received equal treatment and were encouraged to see themselves as fellow victims of aristocratic conflict rather than enemies 215 216.

Technology and Military

Soul Tool Development

The Sun Moon Empire possesses the continent’s most advanced Soul Tool technology. Huo Yuhao and Xiao Hongchen developed a Soul Tool Handgun, which the Worship Hall verified before the emperor rewarded both inventors with viscount titles 83.

The empire also developed offensive Soul Tools usable by people without Soul Power, alarming rival states because of the resulting military imbalance 86 149.

• Lathes and assembly lines expanded Soul Tool production and transformed national strength 211.
• Soul Tool products are widely used in Mingdu’s daily life, not solely for warfare 215 216.
• Xiao Hongchen continued developing both offensive tools and civilian technologies after entering Mingde Hall’s core 319.

Battle Armor

Battle Armor	Documented capability / development
Two-Word Battle Armor	Developed by Huo Yuhao and Gu Yuena; substantially increased Huo Yuhao’s strength 208
Three-Word Battle Armor	Its development was kept secret while Mingde Hall and the Worship Hall concentrated Rank Nine Soul Engineers on overcoming technical barriers 211
Four-Word Battle Armor	Worn by Sun Moon Soul Engineers to reach Rank 95 Super Douluo-level power; Kong Deming’s armor could overwhelm an Ultimate Douluo 211 242

Military Forces

• Rank Nine Soul Engineers — Deployed to defend Mingdu, contain attacks, and protect civilians during high-level battles 216 239.
• Soul Tool Master Legion — The empire’s principal military force during its later campaigns 270.
• Four-Word Battle Armorists — Elite concealed force used in the conflict against the Clear Sky Empire, though Niu Tian and Titan initially repelled their surprise attack 324.
• Fixed Soul Tool Cannon Shells — The empire retained nuclear-level shells as a potential last-resort measure against annihilation 325.

Economy and Civilian Life

Mingdu is depicted as exceptionally prosperous, with ubiquitous civilian Soul Tools, busy markets, and a population visibly satisfied with its standard of living 215. Visitors from sects and academies are struck by the city’s conveniences and by the lack of discrimination toward migrants speaking with Star Luo, Heavenly Soul, or Heaven Spirit accents 215.

During the prolonged war among rival powers, the empire sold Soul Tools and accumulated wealth while the Holy Spirit Church, Star Luo, and Heavenly Soul were drained by attrition 211. It also accepted refugees without exception, with Xu Tianran personally arranging housing at the border 208.

• The empire treats technological development and public welfare as complementary priorities 215 319.
• Its favorable treatment of migrants created a “siphon effect,” drawing more commoners from rival states 216.
• Numerous sects began negotiating relocation or defection after witnessing Mingdu’s prosperity and military strength 216 217.

Story Role / Major Arcs

Rise through Huo Yuhao and Soul Tool Innovation

The empire nurtures Huo Yuhao after his departure from Star Luo, with Kong Deming accepting him as a disciple and the imperial court recognizing him as a national treasure-level talent 49. The emperor’s rewards for Huo Yuhao and Xiao Hongchen’s handgun establish a pattern of state support for their inventions 83.

Strategic Expansion

Rather than immediately invade the original Douluo Three Kingdoms, the empire waited while rival factions exhausted themselves in war, expanded its technology, welcomed refugees, and accumulated wealth 173 208 211. Xu Tianran used the Soul Master Competition to reveal the empire’s power and encourage sects to join voluntarily 211.

Unification War

After displaying Four-Word Battle Armor and defeating major opponents at the competition, the empire declared war on Shrek Academy and the Holy Spirit Church while pressuring Star Luo and Heavenly Soul to surrender 242 244. Although Shrek Academy and Clear Sky Sect attempted to prevent the rival empires’ submission through usurpation, the Sun Moon Empire eventually seized former Star Luo and Heaven Spirit lands and consolidated them 253 318.

The Clear Sky Empire later threatened the Sun Moon Empire with Niu Tian and Titan’s strength. Facing possible defeat, Huo Yuhao proposed an alliance with the ferocious beasts; the Soul Beast Clan arrived during the decisive crisis and aided the empire 325 326 327.

Continental Unification

Kong Deming executed Titan after Di Tian defeated him, ending the war for the continent’s unification 336. The empire spared surviving enemies except those deemed unforgivable, preserving powerful martial soul bloodlines under a plan established by the emperor and Huo Yuhao 336.

Following victory, the empire began changing human attitudes toward soul beasts in recognition of the Soul Beast Clan’s decisive assistance 340.

Trivia
