Sun Moon Empire

Biodata

Geography

• Mingdu — Imperial capital and home to numerous noble clans. Qin Bohai uses his connections among its Soul Douluo families to recruit supporters for the Su Clan 85.
• Shanhai City — The Su Clan’s original residence within the empire, where the family had been established for over a thousand years 1 17.
• Imperial border — Serves as a meeting point for tournament-related negotiations and student exchanges with Shrek Academy 49 86.
• Capital security — At the time of Su Yun’s departure for the tournament, the capital has no Soul Beast detectors, allowing the Snow Empress to move there without her identity being detected 31.

Government and Nobility

Imperial Authority

• The Xu imperial family controls access to the empire’s best cultivation medicines, giving it substantial influence over Soul Masters who depend on pharmaceutical cultivation 26.
• Titled Douluos can serve as imperial retainers. Their noble treatment is less favorable than in the original Douluo Three Kingdoms because of the imperial family’s control over medicine 6 26.
• Imperial succession disputes can devastate noble families: the Qin Clan lost its only Titled Douluo after backing the wrong faction and fell from ducal to earl status 84.

Ducal Succession

Holy Spirit Cult Influence

The Holy Spirit Cult is entrenched within the empire and backs its imperial family. Su Yun identifies its two Limit Douluos as a major obstacle to protecting his clan and eventually overthrowing the Xu rulers 21 78.

According to Qin Bohai, the cult’s predation has made imperial protection essential. Unaffiliated Soul Masters commonly join the empire’s legions to avoid being abducted as cultivation resources. Even noble Soul Masters fear that an offense against the authorities could turn them into bargaining chips in a deal with Evil Soul Masters 85.

Qin Bohai also attributes the population’s conspicuous displays of devotion to the emperor to this insecurity: those who do not demonstrate loyalty risk losing protection against the cult 85.

Cultivation and Soul Engineering

Soul Tools

• Soul Tools are central to the empire’s combat practices, and its Titled Douluos devote much of their time to researching them 12 70.
• This specialization comes at the expense of Martial Soul knowledge and conventional Soul Master cultivation 70.
• Soul Bones are comparatively inexpensive, and absorbing them is not a widespread custom. Jing Hongchen initially regards them primarily as materials for producing Soul Tools 6 13 53.
• The imperial court commands high-level Soul Engineers; four Level 9 Soul Engineers accompany the emperor during his visit to the royal academy 73.

Medicine Refinement

• Refining medicine requires high-grade Soul Tools, ingredient extraction, and multiple processing steps 2.
• Pharmaceutical cultivation allows people with relatively modest innate Soul Power to progress substantially. Su Qingxue assures Su Yun that rank-three innate Soul Power does not eliminate his prospects in the empire 1.
• The empire’s medicines make reaching Level 50 before twenty comparatively accessible, according to Du Weilun 61.
• Their effectiveness drops sharply after Titled Douluo, contributing to the low cultivation levels of many imperial experts 35.
• Rare natural treasures remain scarce; even Xiao Hongchen uses treasures with side effects 8.

History

Xu Kun’s Accession

Xu Kun takes the throne after his imperial brother and female relatives die violently and the former crown prince disappears. He publicly presents his accession as an emergency measure, promising to abdicate if his missing nephew returns. He appoints his son Xu Tianran crown prince 16.

Xu Tianran subsequently commissions the Holy Spirit Cult to destroy the Su Clan, intending to rescue Su Qingxue afterward and secure her loyalty. The attack fails, and Su Yun orders the clan to sell its Shanhai City properties and relocate to the capital 16 21.

After news concerning Xu Tianran spreads among the princes, the emperor orders him dragged away to be beaten to death. Xu Kun fears that his son’s plan to obtain an heir through someone outside the close imperial family would ultimately surrender the Xu dynasty’s realm to another bloodline 33 34.

First Tournament Championship

The Sun Moon Royal Soul Engineer Academy traditionally finishes behind Shrek and has never won the Continental Advanced Soul Master Tournament. Its championship odds stand at one hundred to one, reflecting widespread confidence in Shrek’s continued dominance 30.

During the tournament hosted by the Dou Ling Empire, the academy wagers one hundred million Gold Soul Coins on its own victory. Hoping to protect its expected gambling profit, the host imperial family supplies Shrek with the Sun Moon team’s roster 36 37.

Su Yun’s victories eventually force Yan Shaozhe to concede, securing the academy’s first championship. Jing Hongchen demands that Shrek deliver promised Soul Bones to the Sun Moon border within seven days 49 54.

Xu Kun publicizes the victory as an auspicious achievement of his new reign and holds a grand reception in the capital 54.

Educational Reform and Shrek Exchanges

Following the championship, Xu Kun establishes the Sun Moon Royal Soul Master Academy as an imitation of Shrek’s Soul Master education. The Su Clan Grand Elder wins its headmaster competition, while other clan members obtain senior positions 69 70.

Despite the rivalry, the empire exchanges students with Shrek and later hosts joint classes to extend access beyond the limited exchange places. Xu Kun permits Yan Shaozhe to act temporarily as dean, provided imperial secrets remain protected 73 74.

The exchange ends with further recruitment competition. Su Qingxue and Qin Teng Shan invite Shrek students to remain, and the Soul Engineer among the next generation of Shrek Seven Devils chooses to join the Sun Moon Royal Soul Master Academy 86.

Opposition to the Xu Clan

Su Yun’s hostility toward the dynasty begins with Xu Tianran’s attack and deepens after the victory banquet. He plans to destroy the imperial family after the next tournament, but delays action because of Kong Deming and the Holy Spirit Cult’s senior experts 55 74.

Qin Bohai later offers the Qin Clan’s allegiance, recognizing the Su Clan as a potential challenger to the throne. He identifies widespread noble resentment of the Xu rulers and names the Tian, Liu, and Wang Clans as likely allies 84 85.

Su Yun authorizes recruitment of Soul Douluos above Level 85 by offering a route to Titled Douluo. Qin Bohai pledges that, within three years, at least fifteen new Titled Douluos in the Imperial Family’s Worship Hall could answer the Su Clan’s call. This remains a recruitment promise, not a completed overthrow 85.

External Relations

• Shrek Academy — The empire’s principal educational and tournament rival, but also a partner in student exchanges and joint teaching. Xu Kun personally admires Shrek despite fearing that an imperial descendant studying there could be detained 56 73.
• Dou Ling Empire — Hosts the tournament in which Sun Moon wins its first championship. Its rulers assist Shrek by sharing the Sun Moon roster after accepting the academy’s enormous championship wager 36 37 49.
• Original Douluo Three Kingdoms — Remain targets of Xu Kun’s long-term ambitions. He envisages another thirty to fifty years of development before conquering them 56.
• Earlier anti–Sun Moon coalition — Su Yun attributes the empire’s survival against an earlier allied counterattack to divisions among the opposing countries over interests and spoils 79.
