Background / History

Dugu Xuan is Dugu Ce's grandfather and Dugu Bo's younger brother. In his youth, he was regarded as a Dugu family genius, but the inherited Jade Phosphorous Serpent venom tortured him for decades and nearly killed him. Dugu Bo preserved his life by suppressing the venom at the Ice and Fire Yin-Yang Well and helping him form a Poison Pill; even so, Xuan could survive only within the well's environment for many years. 1

His son—Dugu Ce's father—was humiliated by the Blue Lightning Tyrant Dragon Clan while seeking to marry Yu Yin. The injuries and venom backlash he suffered eventually caused his premature death. This loss gave Dugu Xuan a lasting grievance against the clan and a desire to return to True Dragon Mountain to seek justice. 1 4

Dugu Ce later identified the Ninth-Rank Purple Ganoderma as a remedy suited to Xuan's depleted body. The herb restored his vitality and allowed him to break through to the Titled Douluo realm. 3 Golden Crocodile Douluo then aided him in acquiring a ninth ring from the Nine Nether Poison Flood Dragon, which Dugu Ce artificially pushed to the hundred-thousand-year stage. 4 5

After absorbing the ring, Xuan's venom backlash was suppressed into his dantian, his life force was revitalized, and he adopted the title Nine Nether Douluo in honor of the beast that changed his fate. 5 He subsequently joined Dugu Ce, Dugu Bo, and Golden Crocodile Douluo in confronting Liu Erlong and destroying the Blue Lightning Tyrant Dragon Sect. 6 15 18

Following the sect's fall, Xuan helped establish the Dragon-Serpent Sect on True Dragon Mountain. He was assigned to integrate the former Blue Lightning Tyrant Dragon branch families, later advanced his martial soul again at the Ice and Fire Yin-Yang Well, and condensed a Soul Core under Dugu Ce's guidance. 21 25 26

Appearance

Before his recovery, Dugu Xuan was described as skeletal and deathly, with a withered body and a near-terminal aura caused by long-term venom damage. 2 His condition improves dramatically after his breakthroughs.

• Emerald eyes and jade-green soul power. 15 18
• His evolved martial soul initially gains purple-gold scales and a single horn. 5
• He is recognized by others as the Dugu family genius once believed to have died from poison. 15

Personality

Dugu Xuan is fiercely loyal to his family and carries a deep resentment toward the Blue Lightning Tyrant Dragon Clan for his son's death and the Dugu family's humiliation. He regards Yu Tianheng's captivity and the sect's destruction as repayment of an old blood debt. 15 18

Despite his ruthlessness toward enemies, he is caring and protective toward Dugu Ce. He worries that Ce's exceptional talent will worsen the family's inherited poison problem, supports his grandson's plans, and respects his advanced cultivation knowledge even when it requires Xuan to take risks. 2 26

He is also blunt and proud, readily mocking Dugu Bo and the Blue Lightning Tyrant Dragon martial soul while celebrating the Dugu family's rise. 21 29
