Background / History

Dugu Xin is the only son of Dugu Bo, head of the Dugu Family. He inherited the family’s Jade-Phosphorus Snake martial soul, whose violent poison had devastated the family’s bloodline: the poison killed his mother after it invaded her marrow during her pregnancy. Learning this history made Xin cautious about having children before resolving his martial soul’s mutation. 14

At the Heaven Dou Auction, Dugu Bo purchased a 2,300-year One-Horned Azure-Scaled Python torso bone for Xin. The bone suited his martial soul and carried a trace of dragon bloodline, giving Dugu Bo hope that Xin’s martial soul could mutate and escape the family’s inherited fate. 6

Xin later married Feng Yansha. Xia Feng attended their wedding and presented a four-thousand-year Dragon Lingzhi, which Dugu Bo passed to Xin as a crucial opportunity for his martial soul. 13 14

After consuming the Dragon Lingzhi, Xin broke through from level 38 to level 40, absorbed its soul ring, and evolved his Jade-Phosphorus Snake into the Jade-Phosphorus Azure Flood Dragon. The new martial soul became a top-tier sub-dragon martial soul with poison and wood attributes, freeing him from the ordinary snake lineage and greatly improving his future potential. 14

When Dugu Bo suffered a near-fatal poison backlash, Xin remained at his father’s side and trusted Xia Feng’s family with the crisis. He witnessed Xia Mu save Dugu Bo with the Dragon Core, which also evolved Dugu Bo’s martial soul. 25 26

After Xia Mu returned from Slaughter City, Xin received a Ten-Thousand-Year Ninth-Grade Purple Lingzhi. Refining the medicinal king strengthened his foundation and raised his soul power to level 60, while Feng Yansha’s corresponding Ninth-Grade Ginseng King allowed her to reach level 50. 33 38

Although Dugu Bo urged the couple to have children, Xin and Feng Yansha decided to postpone parenthood and concentrate on cultivation while they were young. 34

Dugu Bo later sent Xin and Feng Yansha with Xia Mu to train on Sea God Island, hoping its opportunities would help secure the Dugu Family’s future. After four years of advancement, Xin had reached level 84. 92 120

Personality

Dugu Xin values gratitude and personal bonds. He openly sought a close friendship between the Dugu and Xia families after recognizing that Xia Feng’s Dragon Lingzhi had transformed his future. 15

He is devoted to his father and was deeply distressed during Dugu Bo’s poison backlash. He also initially refused Xia Mu’s Ten-Thousand-Year Ninth-Grade Purple Lingzhi because he believed the treasure had been won at great personal risk, accepting only after Dugu Bo urged him to do so. 25 33

Xin is hospitable and conscientious in his treatment of allies, personally visiting the Xia Family to congratulate them on their move to Heaven Dou City and directing Feng Yansha to assist Liu Yuer. 15

He also places importance on propriety and formal family relationships, though he has expressed frustration at the increasingly complicated kinship arrangements among the allied families. 38

He proved persistent on the Xia Family’s behalf, persuading several prospective recruits to join them. 52

Abilities & Skills

Jade-Phosphorus Azure Flood Dragon

Dugu Xin’s martial soul evolved from the Jade-Phosphorus Snake after he absorbed a four-thousand-year Dragon Lingzhi soul ring.

• A top-tier sub-dragon martial soul with poison and wood attributes. 14
• Its evolution moved him beyond the ordinary snake lineage and improved his cultivation aptitude. 14 26
• Dugu Bo believed this martial soul gave Xin a chance to become a Titled Douluo. 14
• The former Jade-Phosphorus Snake martial soul carried an inherited poison that could harm its wielder before harming enemies and endangered the Dugu bloodline. 14
• As a snake- and dragon-lineage martial soul, it is heavily suppressed by Liu Yuer’s Crimson Sky Sword, which possesses a natural restraining effect against serpents and dragons. 60

One-Horned Azure-Scaled Python Torso Bone

Xin absorbed a 2,300-year torso bone from a mutated One-Horned Azure-Scaled Python.

• The torso bone was compatible with his martial soul and contained a trace of dragon bloodline. 6 14
• Its improvements contributed to his rapid cultivation to level 38 and set the foundation for his later martial-soul mutation. 14

Equipment / Items

• One-Horned Azure-Scaled Python torso bone — 2,300-year torso bone with a trace of dragon bloodline; absorbed before his martial soul evolution. 6 14
• Ten-Thousand-Year Ninth-Grade Purple Lingzhi — gifted by Xia Mu to strengthen Xin’s foundation, nourish vitality, and accelerate cultivation; accepted at Dugu Bo’s insistence and subsequently refined to reach level 60. 33 38

Relationships

• Dugu Bo — Father and head of the Dugu Family. Dugu Bo devoted major resources to altering Xin’s inherited martial soul and viewed Xin’s successful evolution as the end of the family’s tragic fate. 6 14 Xin remained at his father’s side during the latter’s poison backlash and later awaited Dugu Bo’s emergence from seclusion so that the family could undertake their soul-ring hunts. 25 38 Dugu Bo subsequently sent Xin and Feng Yansha to train with Xia Mu on Sea God Island. 92
• Feng Yansha — Wife. They were introduced as a couple and later married; she remained beside Xin during Dugu Bo’s poison backlash. 11 13 25 She assisted the Xia Family through the Dugu Family’s connections and later reached level 50 after refining Xia Mu’s Ten-Thousand-Year Ninth-Grade Ginseng King. 15 33 38 They agreed to delay having children while pursuing cultivation and later traveled together for training on Sea God Island. 34 92
• Xia Feng — Close friend and sworn elder brother. Xia Feng’s Dragon Lingzhi enabled Xin’s breakthrough and martial-soul evolution, binding the Xia and Dugu families together. 14 15 25
• Liu Yuer — Family friend and Xia Feng’s wife. She and Xia Feng relied on the Dugu Family during their efforts to obtain Xia Feng’s fourth soul ring. 15
• Xia Mu — Junior member of the allied Xia Family and a major benefactor of the Dugu Family. Xin accepted Xia Mu’s Ninth-Grade Purple Lingzhi after initially refusing the gift, then refined it to become a level-60 quasi-Soul Emperor. 33 38 After Dugu Bo acknowledged Xia Mu as his master, Xin and Feng Yansha accompanied Xia Mu to Sea God Island for training. 38 92
• Ye Renxin — Senior ally of the Xia and Dugu families. Xin received Ye Renxin at the Dugu Estate while Dugu Bo was in seclusion, and their families prepared to hunt soul rings together. 38 39
