Background / History

Xu Jingyao’s Reign

Emperor Xu Jingyao pursued recovery, peace, and the development of soul guidance technology. His restraint allowed the population to recover from an earlier war while the empire accumulated substantial reserves, earning him considerable popular prestige 2 6.

Technological growth strengthened an expansionist faction among ministers and imperial nobles. They wanted to annex the other three nations and use their resources to sustain further Soul Tool development. Xu Jingyao’s commitment to stability made him an obstacle to those ambitions 2.

Palace Coup

The coup erupted during a palace banquet celebrating eight-year-old Xu Yan’s return from obtaining his second soul ring. The palace burned, the imperial family was purged, and Mingdu entered a citywide lockdown. Xu Jingyao was among more than thirty people killed in the palace 1 2.

Xu Tianlong seized power with support from radical court officials and nobles. Xu Yan and his elder brother Xu He escaped with Ji Juechen and Yan Feng, but imperial patrols and Aodu Chamber of Commerce trackers pursued them. Xu Tianlong considered Xu Yan the greater threat because of his talent, ambition, and political judgment 2 3.

The Offering Hall did not intervene. Kong Deming defended its nonintervention as an established rule, while Ye Yulin argued that the empire needed a more aggressive ruler. Liao Mengkai opposed this position, maintaining that renewed conquest would sacrifice ordinary people’s recovery to elite ambition 6.

Body Sect Intervention

Prince Xu Tianyuan intercepted the fugitives and attempted to kill Xu Yan and his companions. Du Busi intervened, provoking a confrontation with Kong Deming above Mingdu. Kong’s Soul Tools protected him from Du Busi’s attacks, and the arrival of additional consecrators with Level 9 weapons prompted the Body Sect master to withdraw with the fugitives 11 12 14.

At Xu Yan’s suggestion, Du Busi captured the wounded Xu Tianyuan before leaving. Kong Deming refused pursuit because of Du Busi’s strength. Xu Yan subsequently took the prince’s equipment and killed him, declaring his intention to rebuild the empire and destroy its corrupt ruling faction 15 16.

Strategic Warehouse Raid

Xu Yan exploited the disruption following the coup to organize a raid on the South City Strategic Warehouse. The attackers concealed their soul power, placed commander Wang Xiao and his soldiers under Mo Yuan’s illusion, and entered using Xu He’s still-valid inherited access privileges 16 17 18.

The group emptied the warehouse’s rare-metal reserves and seized its weapons and supplies. Before escaping, Xu Yan instructed Yan Feng to leave a trace of his martial soul’s evil aura near the entrance. The guards remained unaware of the theft even after the illusion ended 18 19.

Xu Tianlong discovered the loss while inspecting security and collecting resources to reward his coup supporters. He threatened Wang Xiao with extermination of his ten clans unless the culprit was found within an hour. The planted aura led him to blame the Holy Spirit Cult, although Liao Mengkai privately found it familiar 20.

Territory and Capital

• Mingdu: A city of towering metal buildings, described as the continent’s pinnacle of soul guidance technology. Its infrastructure includes soul guidance patrol vehicles and an extensive sewer network 1 2.
• Imperial palace: Houses the Offering Hall in its deepest reaches 6.
• Southern Mingdu: Contains slum districts and one of the empire’s most important strategic materials warehouses 7 17.
• Heaven Dou border: The empire shares a border with the Heaven Dou Empire; Xu Yan’s group crosses it after escaping Mingdu 21.

Government and Institutions

Imperial Court

• Post-coup transition: Xu Tianlong temporarily governs as prince regent rather than immediately completing his accession 20.
• Patronage: Rare ores and high-grade Soul Tools are used to reward nobles and senior officials who supported the coup 20.
• Restricted access: Xu Tianran remains excluded from the empire’s core warehouses, privately interpreting this as evidence of his father’s distrust 20.
• Succession politics: Liao Mengkai supports Xu Yan as an ideal heir. Ye Yulin rejects him partly because half of his ancestry comes from the Heaven Dou Empire 7.

Offering Hall

The Offering Hall is described as the empire’s true pinnacle of power and its protective foundation 6.

Institution	Documented Function

High-Grade Weaponry

• Level 9 Soul Cannons: Xu Yan reports that the empire possesses at least fifty, with the actual total potentially higher. Even an ordinary cannon of this grade can deliver a shot equivalent to a Titled Douluo’s all-out strike 16.
• Fixed Soul Guidance Shells: A Level 9 shell carried by Xu Yan is powerful enough to flatten an entire city. Such ammunition can be fired using a suitable cannon mount 11 19.
• Silver Moon Divine Light Shield: Kong Deming’s Level 10 defensive Soul Tool survives Du Busi’s space-breaking punch, although the spiritual impact severely depletes Kong’s spiritual power 13 14.
• Sun Moon Divine Needle: Ye Yulin’s target-locking Level 9 Soul Tool helps deter Du Busi from continuing the confrontation 14.
• Heaven-Burning Nine-Sun Cannon: Xu Tianyuan’s weapon fires nine high-temperature rays and can use Level 9 flame shells. Xu Yan judges that, combined with its owner’s Sun Martial Soul, it could instantly kill an ordinary Super Douluo, but requires a lengthy charge 16.

Detection and Security

• Aerial surveillance: High-altitude detection tools locate Xu Yan’s group in the southern slums and allow Offering Hall elders to observe them remotely 7 10.
• Underground searches: Patrols use detection Soul Tools to scan Mingdu’s sewer network 3.
• Life-sign alarms: Strategic warehouse guards carry heart-rate and life-sign sensors capable of alerting the Imperial City within one second if they are killed or rendered unconscious by severe injury 17.
• Targeting support: Overhead Soul Power Detection Soul Tools provide early warning and precise targeting for Soul Cannons 17.

Access and Limitations

• Unequal distribution: Combat Soul Tools are widespread but remain concentrated among nobles; low-ranking assassins lack access to comparable equipment 10.
• Common storage technology: Storage Soul Tool Rings are nearly universal in the empire, though most hold only two to five cubic meters 17.
• Cultivation weakness: The empire’s traditional soul-master cultivation foundations fall short of those of the Douluo Three Kingdoms 23.
• Bloodline difficulty: Sun Moon bloodlines are described as making cultivation—and especially advancement to Super Douluo—more difficult 11.

Strategic Resources

The South City Strategic Warehouse has three underground levels and fortifications designed to withstand Level 9 fixed-weapon attacks 18.

Level	Contents Before the Raid
First	Rare metals and strategic ores, in quantities valuable enough to equip several Soul Engineer Corps 18
Second	Standard Soul Tools, Level 4–7 fixed shells, Soul Cannons, defensive equipment, and rechargeable “Milk Bottles” 18
Third	Level 8 cannons and shells, five Level 9 cannons, and ten Level 9 shells 19

• Five crates remembered by Xu He were already missing. Xu Yan inferred that Xu Tianlong had taken them as contingency weapons for the coup 19.
• The theft deprived the new regime of supplies intended to strengthen the royal family and reward its supporters 20.

Relationships

• Body Sect — Rescues Xu Yan’s group, clashes with imperial defenders, and raids the strategic warehouse. Kong Deming vows to destroy the sect after Xu Tianyuan’s capture 12 14 15 19.
• Holy Spirit Cult / Xishui Alliance — Xu Tianyuan avoids antagonizing Nangong Wan and allows him to take Yan Feng. Xu Tianlong later blames the Holy Spirit Cult for the warehouse theft 12 20.
• Aodu Chamber of Commerce — Supplies trackers and assassins for the pursuit of the surviving princes 3 4.
• Xu Yan — A surviving imperial prince turned opponent of the ruling faction; he joins the Body Sect while retaining the ambition to rebuild the empire 13 16.
• Douluo Three Kingdoms — Targets of the expansionist court faction’s proposed annexation and resource seizure 2.
