Background

The Sun Moon Empire is one of the Four Great Empires and possesses a territory nearly equal in size to the combined Douluo Three Empires. Its wider distribution of martial-soul awakenings gives the Body Sect a larger pool of potential recruits than the three western empires. 47 106

Unlike the Douluo Three Empires, the Sun Moon Empire develops both Soul Tool and Martial Soul disciplines. Its academies use Practical Control departments to help students retain Soul Tool advantages without neglecting Martial Soul cultivation. 7

The empire’s Soul Tool education is unusually standardized: it is the only place on the continent stated to provide unified theoretical and practical instruction in Soul Tools. 7

Soul Tool Technology

Education and Civilian Development

The empire’s Soul Tool ecosystem extends beyond combat equipment. Its Soul Tool Halls use Soul Tool lighting, conveyor systems, multifunctional reception desks, and separate combat, auxiliary, and civilian sections. 49

  • Soul Engineer clans can receive state support and annual rare-metal allocations for training disciples. 57
  • Civilian Soul Tool development is a major field alongside military Soul Tools and personal-combat equipment. 46 49
  • A Level 4 Soul Master from the empire may possess more detailed Core Array knowledge than a Level 6 Soul Master from the Heaven Dou Empire, reflecting the gap in technical environment. 48

Rare-Metal Control and Technological Blockade

The Sun Moon Royal Family does not necessarily mine every rare-metal vein itself, but it controls the Level 9 mining Soul Tools required for extraction. Because those tools wear down, the state can effectively regulate how much rare metal is mined. 57

  • Advanced Soul Tool technology exported to the Douluo Three Empires is deliberately limited; foreign powers may only access what the empire permits them to learn. 61
  • The export restriction on rare metals is a central part of the technological blockade against the Douluo Three Empires. 57
  • Researchers capable of studying Level 9 Soul Tools are monitored, while many high-level talents are drawn into Mingde Hall. 57
  • Rare metals nevertheless reach the Douluo Three Empires through smuggling networks and black-market trade. 7 45 54

Military Soul Tools

The empire’s military strength rests heavily on advanced Soul Tools, especially Fixed Soul Guidance Shells.

  • The Sun Moon Royal Team fielded one Soul Emperor and six Soul Kings, with Ma Rulong able to use the Level 8 Sword of Judgment and the other members equipped with exceptionally costly Soul Tools. 23 26
  • Mingde Hall developed Soul Tools specifically to interfere with Su Fan’s Space Jump after observing it in the tournament. 27
  • The team deployed 108 Soul Tool cannons during its match against the Dou Ling Team. 27 28
  • Its escape measures included automated decoy Soul Tools that simulated the team’s soul-power signatures and an eighth-level Fixed Soul Guidance Shell whose explosion could be felt from a great distance. 41
  • Mingde Hall possesses at least dozens of Level 9 Fixed Soul Guidance Shells. A single shell can destroy an army encampment or force the abandonment of a city. 65

Relations

  • Douluo Three Empires — The empire restricts their access to rare metals and advanced Soul Tool technology, while their merchants and noble families rely on smuggling to obtain those resources. 7 45 57
  • Body Sect — The sect entered the empire under negotiated conditions to recruit Body Martial Soul masters, later infiltrated its territory on a wider scale, and launched an assault on Mingde Hall. 46 47 64 106
  • Su Family — A Ming Capital Soul Engineer family that cooperated with Su Fan and Du Busi over the Aperture Method while attempting to prevent Su Fan from contacting Mingde Hall or the Royal Soul Master Academy. 46 48
  • Sun Moon Royal Team — The empire’s elite tournament team; its members relied on Mingde Hall’s countermeasures, Soul Tool firepower, and decoy systems while transporting the Hundred-Thousand-Year Soul Beast embryo. 27 41
  • Holy Spirit Cult and Xishui Alliance — The cult and its affiliated underground power became deeply entrenched in the empire before the Royal Family turned on them, dismantling the Xishui Alliance and executing identified Evil Soul Masters. 52 121

Story Role / Major Arcs

Soul Master Tournament

The Sun Moon Royal Team entered the tournament as one of the final four teams and faced the Dou Ling Team in the semifinals. It neutralized Su Fan’s initial Space Jump tactic with dedicated spatial-interference Soul Tools and answered his battlefield control with overwhelming cannon fire. 26 27 28

Su Fan’s Evil Spirit Mirror Annihilation repeatedly destroyed the team’s Milk Bottles, creating a soul-power crisis that undermined its Soul Tool-heavy fighting style. The Sun Moon Royal Team was ultimately eliminated by the Dou Ling Team before the final. 28 29 32

Embryo Transport and Border Crossing

After acquiring the Hundred-Thousand-Year Soul Beast embryo at auction, the Sun Moon Royal Team returned toward Ming Capital using automated Soul Tool decoys and an eighth-level Fixed Soul Guidance Shell to misdirect pursuers. The Body Sect failed to intercept it. 40 41

Aperture Method Negotiations

Su Fan’s disclosure that Core Arrays could be inscribed into apertures drew intense interest from the empire’s soul-engineering circles. The Aperture Method demonstrated that apertures could serve as superior internal carriers for Core Arrays, bypassing some limitations imposed by rare metals. 46

The Su Family accepted a deal for aperture-condensation techniques in exchange for Soul Tool study access and limited entry for Body Sect personnel. The agreement enabled up to fifty Body Sect members to enter the empire for recruitment, provided they did not participate in politics or important Soul Tool projects. 46 47

Attack on Mingde Hall

The Body Sect attacked Mingde Hall to seize the Hundred-Thousand-Year Soul Beast embryo. Du Busi, having reached the Limit Douluo realm, led the assault while Elder Qilin retrieved the embryo; Mingde Hall activated a spatial lockdown to prevent the raiders’ escape. 64

The raid exposed the empire’s deeper military reserves. Du Busi withdrew after discovering Mingde Hall’s Level 9 Fixed Soul Guidance Shells and sensing the danger posed by Long Xiaoyao and the Black Market’s Evil Soul Masters. 65

Aperture Soul Tool Research

The Sun Moon Royal Family later funded Su Fan’s Aperture Soul Tool research with Crimson Sun Divine Iron. It agreed to provide ten standard pieces each month for three years, with Mingde Hall establishing a laboratory on Snow Demon Mountain for the project. 92

The Royal Family also provided Linkage Technology documents, valuing Aperture Soul Tools for their potential to store soul power, propel it, and inscribe Core Arrays directly within a soul master’s body. 95

Martial Law and Holy Spirit Cult Purge

After the Holy Spirit Cult suffered major losses, Xu Tianran acted against it without hesitation. The empire entered martial law, the Xishui Alliance collapsed overnight, and the Royal Family seized its assets while executing located Evil Soul Masters. 121

The same crisis prompted the empire to place Ming Capital under total lockdown, keep defensive Soul Tools charged, and deploy Soul Master Legions to search for Body Sect forces after Du Busi re-entered its territory. 121
