Background / History

Dugu Xin is Dugu Bo's eldest son and Dugu Chen's older brother. While Dugu Chen travels, Xin remains at Dugu Residence, oversees household affairs, and honors his father with newly harvested Spirit Tea from the Ice and Fire Yin Yang Well 17. He is also the father of Dugu Yan, whom Dugu Chen calls “Yanyan” 23.

Before the Saintess Ceremony in Wuhun City, Xin researches notable independent soul masters in hopes of recruiting promising experts as retainers for the Dugu family 37. He accompanies Dugu Bo and Dugu Chen to the ceremony, where he enters Spirit Hall's younger-generation contest.

Xin defeats Chen Dongqing through poison-based attrition tactics, then forces Blue Lightning Tyrant Dragon Sect disciple Yu Xiaolie to concede after exhausting his soul power against the Jade-Scale Serpent Emperor Poison 39 40. His tournament run draws the interest of Qian Xunji and earns praise for his stable, disciplined combat style 38 40 41. He is later defeated by Tang Hao after deploying his Martial Soul True Body 41 42.

Dugu Chen gives Xin the Gale Demon Wolf Right Leg Bone earned as a tournament reward. Under Dugu Bo's insistence, Xin absorbs it and approaches the Soul Douluo threshold 45 46. After reaching level eighty, he travels with Dugu Bo and Dugu Chen into the Extreme North in search of a suitable Hundred-Thousand-Year eighth Soul Ring 52 60.

At Dragon Ridge Snow Mountain, the group battles a Frost Dragon. Rather than kill it outright, Dugu Chen arranges for the dragon to sacrifice itself to Xin. Xin endures three days of fusion and emerges with a Hundred-Thousand-Year Soul Ring, a Frost Dragon Dragon Soul, and a torso Soul Bone 67 68.

Appearance

Dugu Xin is a young man in his twenties who carries himself with unusual composure and a deep, steady aura 35 38.

• During martial soul possession, his eyes become emerald-green vertical slits 38.
• His Jade-Scale Serpent Emperor manifests as a large, robust jade serpent with a horned head and kingly bearing 38 40.
• Following his Frost Dragon fusion, his eyes flicker between emerald and ice-blue; his skin is described as silver-white with a cold luster 68.

Personality

Xin is calm, mature, and restrained. He handles family matters, treats guests courteously, and remains composed even while surrounded by admirers and political factions in Wuhun City 17 35 36.

He is filial toward Dugu Bo and accepting of Dugu Chen's antics, though he openly complains when his younger brother drags him into punishment 35. He is also practical and selfless: when the search for a Hundred-Thousand-Year Soul Beast appears fruitless, he considers settling for a high-age Ten-Thousand-Year ring rather than force Dugu Bo and Dugu Chen to continue suffering through the Extreme North for him 61.
