Background / History

The Sun Moon Empire originated on the Sun Moon Continent, which collided with the Douluo Continent thousands of years ago. Having unified its original continent, the empire fought the Original Douluo Three Kingdoms in the Holy War, initially gaining the upper hand through superior spirit tool technology. Its spirit tools decisively outclassed Tang Sect hidden weapons during the conflict. 24

Shrek Academy ultimately rallied more than one hundred Titled Douluo to defeat the empire. The Sun Moon Empire was forced to cede territory, pay reparations, rename the Sun Moon Continent as the Douluo Continent, and accept unequal treaties. 24 25

Under the former emperor, the empire observed the treaty, restrained the War Hawk Faction, restricted military-grade and large-scale destructive spirit tools, and prioritized civilian research. These policies raised living standards above those of the Original Douluo Three Kingdoms and won broad popular support. 25

The former emperor, empress, and Crown Prince Xu He died in a single night; the War Prince seized military control and ascended the throne with the backing of the Five Great Guardian Hands and Royal Offering Institute. Opposition was violently suppressed. 68 Under the new regime, previously suspended military projects resumed, producing major advances in detection, long-range, close-combat, and humanoid spirit tools. 89

Following the Mingdu Great Explosion, the empire rebuilt its strength and restored Mingde Hall under Starry Sky Douluo Ye Yulin rather than Jing Hongchen. 362 It later launched a surprise war against the Star Luo Empire, using advanced reconnaissance, Spirit Tool Master Legions, fixed-array cannon shells, and soul-guidance mechs to overwhelm the Northwest Army Group. 418 436

Territory and cities

Mingdu

Mingdu is the imperial capital and is regarded as the Douluo Continent's most prosperous and technologically advanced city. It has no city walls; its defense relies on spirit tools, including four High-Energy Compression Array Spirit Tools that supply core energy. 24 27

• Foreign merchants from the Original Douluo Three Kingdoms trade freely in the city and are treated favorably. 27
• Residency passes require only a registered name, age, and place of origin; officials do not verify whether this information is truthful. 27
• The city uses soul tool screens for public broadcasts and communications. 238
• The Imperial Palace is protected by layered defensive soul tools and soul-guidance barriers, which can stop even fixed soul tools. 315

Coastal territories

The empire permanently stations Spirit Tool Master Legions in coastal cities to repel recurring Sea Soul Beast incursions. Sea soul beasts are also treated as a cultivation resource because their meat can aid soul master cultivation. 26

Mingdou Mountain Range

The Mingdou Mountain Range forms part of the border with the Star Luo Empire and serves as a major military theater. The empire concealed an army of more than one million troops there through advanced detection and intelligence-denial spirit tools. 416 418

Society and education

The Sun Moon Empire is the only known nation to provide free Martial Soul Awakening for commoners. The policy both identifies talented children and gathers information on the next generation of Mingdu residents. 30

Common-born talents such as Luan Feng and Luan Yu were trained by the empire after awakening, entered the Sun Moon Royal Spirit Tool Master Academy, and eventually joined Mingde Hall. 30

The empire's strongest social and professional networking platform is the Sun Moon Royal Spirit Tool Master Academy. 172

Spirit tool technology

The empire possesses the continent's most advanced spirit tool technology and greatest wealth. Its technological lead over the Original Douluo Three Kingdoms is repeatedly described as overwhelming. 235 418

Civilian applications

• Civilian spirit tools are widespread in Mingdu and at the Sun Moon Royal Spirit Tool Master Academy. 89
• Academy screens adapted from communication spirit tools display spirit-tool crafting footage. 89
• Flying spirit tools are common enough that the empire structured tournament rules around aerial combat. 238

Military applications

• Detection Spirit Tools — Conceal troop deployments and make enemy reconnaissance extremely difficult. 418 421
• Flying Spirit Tools — Give the military mobility and make retreat difficult for opposing armies. 428
• Rank 9 Fixed-Array Soul Cannon Shells — Used for long-range strategic bombardment. 416 418
• Soul Guidance Mechs — Advanced humanoid combat equipment deployed by the Scorching Knight Legion. 416
• Sun Moon Divine Needle — One of the empire's foremost Ninth Level Spirit Tools; deployed against White Tiger Duke Dai Hao. 428
• Tenth-Grade Soul Tools — Kong Deming's Silver Moon Divine Light Shroud reached demigod-level power. 345 350

Military

Five Great Guardian Hands

The Five Great Guardian Hands are the empire's elite Spirit Tool Master Legions. The Royal Spirit Tool Master Legion is the strongest and is absolutely loyal to the emperor. 33

During the continental tournament, the empire publicly paraded five elite legions:

• Infantry Spirit Tool Master Legion
• Fire Phoenix Spirit Tool Master Legion
• Terror Claw Spirit Tool Master Legion
• Evil Monarch Spirit Tool Master Legion
• Imperial Dragon Spirit Tool Master Legion 239

The Sun Moon Royal Spirit Tool Master Legion was presented as the strongest among the legions. 239

Notable formations

• Fire Phoenix Spirit Tool Master Legion — Formerly commanded by Fire Phoenix Douluo Luan Feng; Xu Tianran intended to transfer its command to Ju Zi. 29 235
• Evil Monarch Spirit Tool Master Legion — Commanded by Wang Yihang during the Mingdou campaign. 416
• Scorching Knight Legion — Uses advanced Soul Guidance Mechs; Liu Xing and Firefly are associated with the legion. 89 416
• Royal Spirit Tool Master Legion — The empire's strongest legion and one of its principal displays of military dominance. 33 239

Foreign relations

The empire has long maintained a hostile relationship with the Original Douluo Three Kingdoms, with frequent small-scale border conflicts even during the former emperor's period of restraint. 10 25

It formed a strategic alliance with Spirit Hall. Spirit Hall provides high-end combat support and rare-metal resources, while the Sun Moon Empire supplies advanced spirit tool technology that can improve conditions and influence on Spirit Hall's continent. 306

The empire's relationships with the Earthly Dragon Gate and other Original Douluo Three Kingdoms factions remain politically sensitive; Luan Yu's identity as a Rank 9 Spirit Tool Master and sister of a legion commander had to be concealed from the Earthly Dragon Gate. 75 76
