Background / History

Preparations for the Throne

Xu Chengjing began secretly plotting against his brother, Emperor Xu Chengye, on the day his eldest son Xu Tianran awakened the Purple Brilliant Heaven Destroying Dragon Martial Soul. Xu Tiance’s knowledge of the original course of events placed the intended coup three years after his own awakening ceremony 1.

Xu He’s awakening of Twin Martial Souls and Innate Full Soul Power threatened those plans, particularly when Xu Chengye immediately appointed the boy Crown Prince. Xu Chengjing briefly showed concern, then concealed it behind apparently sincere congratulations 1.

The ceremony soon shifted in his favor. His fourth son, Xu Tiance, awakened Sun-Moon Radiance and became Kong Deming’s disciple. Xu Chengjing interpreted Kong’s choice as assurance that the Offering Hall’s chief would not oppose his bid for the throne. Tiance’s subsequent confirmation of Innate Full Soul Power reinforced his conviction that his family was destined to rule 2 3.

Securing Support and Choosing an Heir

Xu Chengjing repeatedly sought Jing Hongchen’s backing, but the Mingde Hall master initially avoided committing himself. After Tiance became Kong Deming’s final disciple, Jing Hongchen visited the prince’s manor uninvited and agreed to cooperate. Xu Chengjing recognized this change as a direct consequence of his son’s new patronage and decided to accelerate his plans 17.

He also investigated the compound Kong Deming had built in Mingdu. Unable to learn much through his agents, he summoned Tiance, who disclosed that the entire Body Sect had relocated there. Xu Chengjing welcomed the sect’s arrival as a major increase in the military strength he expected to command as emperor 21 22.

Despite his preparations, he remained reluctant to act without a clearer indication of Kong’s intentions. Tiance resolved that uncertainty by revealing that Kong had asked whether he wanted to become Crown Prince. Xu Chengjing took this as an endorsement of his own accession and decided to make Tiance his successor. He intended Xu Tianran, his previously favored heir, to inherit the title of Prince Purple Brilliant instead 22.

Palace Coup

With his coalition assembled, Xu Chengjing ordered a concealed Soul Tool signal to begin the uprising. Mingde Hall and three Soul Engineer corps moved against the palace, while the Offering Hall refrained from intervening 23.

Supporter	Contribution to the coup
Kong Deming and the Offering Hall	Tacit approval and nonintervention removed Xu Chengjing’s principal concern 22 23.
Jing Hongchen and Mingde Hall	Supplied core Soul Tools, deployed two Level 9 and six Level 8 Soul Engineers, and sealed the palace’s approaches 23.
Xu Tianyuan — Imperial Dragon Soul Engineer Corps	Broke through the palace gate and defensive array; publicly justified the rebellion as necessary to protect the empire 23.
Luan Feng — Fire Phoenix Soul Engineer Corps	Committed her corps to the palace assault 23.
Liao Mengkai — Terror Claw Soul Engineer Legion	Committed his legion to the palace assault 23.

Xu Chengjing entered the palace with Xu Tianran and captured Xu Chengye and his consorts. He was angered to discover that Xu He had escaped unnoticed despite the forces surrounding the palace 23 25.

Confronting his brother, Xu Chengjing condemned his conciliatory foreign policy. He accused Xu Chengye of failing to hold Dai Hao accountable for an attack on a Sun Moon border town and of endangering the empire by proposing to share its core Soul Tool technology. Xu Chengye rejected these justifications, insisting that personal ambition motivated the rebellion 25.

Du Busi then arrived with Tiance and the recaptured Xu He. He publicly confirmed both his position as Tiance’s second teacher and the Body Sect’s allegiance to the empire. The corps commanders began addressing Xu Chengjing as “Your Majesty,” and Xu Chengjing ordered Xu Chengye, his consorts, and his children killed 25.

Early Reign

The coup established Xu Chengjing as emperor, and Xu Tiance became Crown Prince. Xu Chengjing remained in the prime of life and occupied with his ambitions, leaving Tiance free to continue training rather than immediately assuming substantial duties 26 27.

The Holy Spirit Cult considered exploiting the change of ruler. Zhongli Wu proposed helping Xu Chengjing consolidate power in exchange for permission to operate openly, but Ye Xishui judged direct cooperation risky: the new emperor had spent years building his foundation and already possessed strong military backing. She instead chose to approach Tiance 26.

Personality

Xu Chengjing is an ambitious hardliner whose political goals contrast sharply with Xu Chengye’s preference for peace and diplomacy. He sees the empire’s technological advantage as something to protect, arguing that rival empires would turn equivalent Soul Tool weaponry against it if given access to its technology 12 25.

He is skilled at concealing his reactions. During the awakening ceremony, he suppresses both alarm at Xu He’s success and delight at Tiance’s rise beneath courteous remarks. His caution also extends to political action: even after securing Mingde Hall’s support, he waits for reassurance about Kong Deming before launching the coup 1 3 22.

His treatment of succession is pragmatic and ruthless. He shifts his preferred heir from Tianran to Tiance when Kong’s favor makes the younger son more advantageous, and after taking power he orders the defeated emperor’s entire captured family killed 22 25.

• Within his residence, only he and Xu Tianran are identified as having awakened it 1.
• His cultivation rank, Soul Rings, and specific Soul Skills are not disclosed in the provided chapters.

Relationships

• Xu Chengye — Brother and predecessor. Xu Chengjing overthrows him, condemns his foreign policy, and orders his execution 1 25 26.
• Xu Tiance — Fourth and youngest son; chosen Crown Prince. Tiance’s talent and influential teachers provide decisive political advantages for his father 2 17 22 26.

• Xu He — Nephew and former Crown Prince. His exceptional awakening initially threatens Xu Chengjing’s plans; his attempted escape is stopped before the new ruler orders the captured family killed 1 25.
• Kong Deming — Respected imperial power broker. Xu Chengjing treats his approval as essential to a secure seizure of the throne 2 22 23.
• Jing Hongchen — Crucial coup ally whose support follows Tiance’s appointment as Kong’s final disciple 17 23.

“The moment the Three Great Empires of Douluo Continent gained Soul Tool technology that could rival ours, they would turn their cannons on the Sun Moon Empire!” 25

Trivia

• Tiance’s intervention accelerates Xu Chengjing’s coup rather than originating it; his father was already preparing to seize power 1 18.
• Tiance contrasts the vigorous newly crowned emperor with the sickly Xu Chengjing of the original storyline, whose later death he associates with Huo Yuhao’s explosion in Mingdu. That death has not occurred in the events shown 27.
