Background

Xie Biyan originated from the Dou Qi Continent, where he served as the Supreme Elder and effective controller of the Ten Thousand Scorpion Sect. Before being brought to the Douluo Continent, he was a Dou Zong and a poison cultivator versed in ruthless secret arts and bloodline-tracing techniques. 12 16

The system deployed him as Bai Shu's guardian and converted his cultivation into the Douluo power system. Regarding Bai Shu as the one who gave him a new life and hope of further advancement, he immediately pledged himself as Bai Shu's servant. Bai Shu subsequently granted him the title Ten Thousand Scorpion Douluo. 11 12

His advanced age before the conversion was partly caused by old battle injuries, but chiefly by the long-term erosion of his life essence through poison testing and poison cultivation. The Eight-Petaled Mysterious Ice Grass and Blazing Apricot purified and fused these accumulated toxins, healed his injuries, and restored his remaining lifespan to roughly four to five hundred years. 32

Appearance

Xie Biyan's appearance changed drastically after consuming immortal herbs.

• Before restoration — A hunched, white-haired old man in plain clothing, with murky yet sinister eyes. He used a black wooden cane topped with a scorpion head that emitted a faint purple toxic glow. 12
• After restoration — A muscular, middle-aged man around forty with black hair, a powerful build, and facial features still recognizably similar to his elderly form. His formerly raspy voice became deep and resonant. 31
• His Blood Demon Scorpion Emperor manifestation is a colossal scorpion more than ten meters long, with dark green metallic armor, blood-colored patterns, giant pincers, and a venomous stinger. 12
• When fighting the Blue Silver Emperor, the manifestation displayed purple, red, and blue poison markings across its scarlet carapace. 66

Personality

Xie Biyan is fiercely loyal and deferential to Bai Shu, consistently addressing him as “Young Master” and treating his safety as his foremost duty. His loyalty extends beyond obedience: he takes initiative in anticipating threats, gathering intelligence, and securing Bai Shu's interests without needing explicit orders. 19 39 49

He is also ruthless, bloodthirsty, and takes satisfaction in an enemy's despair. During Tang Hao's defeat, he deliberately revealed painful truths to break Tang Hao psychologically before his death. 16 He considered prolonging Tang Hao's suffering with the Ten Thousand Poison Heart-Devouring Array, but abandoned the idea because returning to protect Bai Shu took priority. 17

Despite his brutality, he is deeply moved by Bai Shu's concern and generosity. Bai Shu's gift of poison-aligned immortal herbs strengthened his devotion further. 14 30 31 His protectiveness can make him visibly anxious when Bai Shu is endangered or undergoing an unpredictable transformation, though he remains disciplined enough not to interfere recklessly. 52 54

Abilities & Skills

Blood Demon Scorpion Emperor

Xie Biyan's martial soul is a poison-aligned scorpion martial soul of exceptional destructive power. 12

• Possesses nine soul rings: two yellow, two purple, four black, and one hundred-thousand-year red ring. 12
• Can transform through Avatar of the Martial Soul into a blood-colored giant scorpion. 15
• Can mutate his arm into an enormous metallic scorpion pincer capable of smashing through stone and opening a cave entrance. 12
• His martial soul's poison and pressure can overwhelm ordinary Title Douluo. 26
• His seventh Soul Skill, Bone-Eroding Heart Pierce, inflicts a poison capable of threatening to spread through the roots and life essence of the Blue Silver Forest. 66

Poison Mastery

A former poison cultivator, Xie Biyan's poison expertise surpasses Dugu Bo's and includes both direct combat toxins and covert control methods. 12 26

• Magic Poison Spot — His innate poison; he claims it can kill even a level 99 Limit Douluo if unleashed at the cost of his life. 12
• Corrosive Poison Claw — Forms a poisonous spectral claw capable of corroding targets; he can use it without manifesting his martial soul. 25
• Can create venom barriers that dissolve hostile attacks, including Dugu Bo's petrification rays. 26
• His scorpion-headed cane can seize and absorb Dugu Bo's Azure Phosphorus Serpent Emperor Poison, stripping Dugu Bo of control over it. 26
• Secretly implanted Dai Hua with a colorless, odorless Poison Seal merged with his Soul Power; Xie Biyan can kill him with a thought if he becomes disloyal. 49
• He passed poison-cultivation techniques and secret arts to Dugu Bo, contributing to Dugu Bo's ability to overcome his inherited poison backlash and later contend with ordinary Title Douluo. 29 102

Blood Demon Poison Domain

Xie Biyan's domain allows him to dominate an enclosed battlefield and heavily suppress opponents. 42

• Yue Guan and Gui mei were unable to escape or meaningfully resist within it. 42
• His domain suppressed a Star Luo Title Douluo enough for Yue Guan and Gui mei to capture him almost immediately. 46
• He can form invisible barriers to contain battle aftermath and prevent collateral damage outside a designated area. 46
• He can create large poison formations to obstruct intruders and Spirit Beasts. After Bai Shu's martial soul evolution destroyed an earlier formation, Xie Biyan reestablished one that helped repel the beast tide around the Ice and Fire Yin Yang Well. 54 56

Soul Cores and Converted Cultivation

Xie Biyan retained advantages from his former cultivation after conversion to the Douluo system. 15

• His former poison-attribute Dou Qi crystal transformed into a Soul Core, an advantage unavailable to ordinary Title Douluo. 15
• His Soul Core continuously replenishes Soul Power and allowed his injuries from Tang Hao's ring detonation to heal at a visible rate. 16
• By level 98, he possessed two Soul Cores. 43
• His Soul Cores provide the foundation for his confidence in fighting above his nominal rank. 15 43

Concealment and Perception

Xie Biyan uses Ten Thousand Scorpion Sect techniques to remain hidden and detect threats. 19 39

• Identified Xiao Wu as a transformed hundred-thousand-year Soft Bone Rabbit through her abnormal aura. 19
• Detected concealed observers in Sunset Forest and pursued one who attempted to flee. 25
• Remained undetected while protecting Bai Shu at an auction, including by Dugu Bo and other Title Douluo. 39
• Perceived the higher-quality power obstructing Xiao Wu's attempt to condense a thousand-year spirit ring. 37
• Although special auction-room materials could block his ability to identify individuals, he could still sense the presence of multiple Title Douluo and two Super Douluo within the venue. 39
• Maintained constant spiritual surveillance while accompanying Bai Shu through the Blue Silver Forest and prepared to evacuate him at the first sign of danger. 63

Equipment

• Scorpion-headed black wooden cane — His original cane, which emits a purple toxic glow and was modified by the system into a treasure comparable to a Level 7 Soul Guidance Device. It can fire highly corrosive venom attacks and absorb powerful toxins. 12 17 26
• Storage ring — Carries supplies and equipment for Bai Shu's group, including Bai Shu's dagger during their journey through Sunset Forest. 25
• Black robe — Manifested after his restoration to middle age. 31
• Ten-thousand-year soul bone — Rewarded to him by Bai Shu for his service. 77

Relationships

• Bai Shu — Master and Young Master. Xie Biyan was deployed as Bai Shu's guardian, pledged his service to him, and protects him without reservation. 12 39
• Tang Hao — Enemy targeted by Bai Shu. Xie Biyan ambushed, defeated, and killed him after a fierce battle. 14 15 16
• Xiao Wu — Bai Shu's companion whose transformed spirit-beast identity Xie Biyan discovered; he later assisted Bai Shu during her spirit-ring condensation. 19 37
• Dugu Bo — Initially confronted as an intruder in Sunset Forest. Xie Biyan's overwhelming poison mastery helped force Dugu Bo to consider Bai Shu's offer, and he later taught Dugu Bo poison cultivation techniques and secret arts. 26 29 102
• Yue Guan and Gui mei — Opponents whom Xie Biyan overwhelmed and delivered to Bai Shu, later becoming fellow subordinates. They subsequently fought alongside him to defend the Ice and Fire Yin Yang Well from a beast tide. 42 43 54 56
• Dai Hua — Subordinate secretly restrained by Xie Biyan's Poison Seal to ensure loyalty. 49
• Blue Silver Emperor — An adversary in the Blue Silver Forest. At Bai Shu's command, Xie Biyan poisoned it with Bone-Eroding Heart Pierce after it attempted to evade its obligations through its forest-spanning root network. 63 66

Story Role / Major Arcs

Deployment and Tang Hao's Death

Xie Biyan appears as Bai Shu's system-provided guardian and immediately demonstrates level 96 Super Douluo strength. He retrieves the Blue Silver Emperor Right Leg Bone with Bai Shu, then ambushes Tang Hao outside Notting City on Bai Shu's orders. 11 12 14

Tang Hao's ring detonation injures but fails to kill Xie Biyan. Xie Biyan ultimately defeats him, taunts him with Bai Shu's identity and Tang San's connection to the absorbed spirit bone, and survives the subsequent interference of the Asura God's consciousness. 15 16 17

Guardian of Bai Shu's Early Growth

Xie Biyan protects Bai Shu in Notting City, investigates Xiao Wu's true identity, drives Bai Shu's carriage during the journey to Sunset Forest, and guards him while he absorbs his second spirit ring. 19 23 25

When Dugu Bo intrudes on Bai Shu's ring absorption, Xie Biyan easily counters the Poison Douluo's attacks before stopping at Bai Shu's command. 26

Immortal Herb Transformation

Bai Shu grants Xie Biyan two immortal herbs formed from rare poisons, specifically to strengthen his poison cultivation and prepare him for stronger future enemies. 30

The herbs restore Xie Biyan's lifespan and youth, transform him from a frail elder into a middle-aged man, raise him to level 97, and bring him to the threshold of level 98. 31 32

Recruitment and Faction Enforcement

Xie Biyan covertly protects Bai Shu during the Heaven Dou auction, defeats Chen Xin's sword intent in a single clash, and helps establish Bai Shu's reputation among major powers. 34 35 39

He uses the Blood Demon Poison Domain to defeat and capture Yue Guan and Gui mei, enabling Bai Shu to recruit them. He later contains the collateral damage from their battle against a Star Luo imperial elder. 42 43 46

Securing Dai Hua's Loyalty

After Dai Hua joins Bai Shu's faction, Xie Biyan secretly places a Poison Seal inside him as a safeguard against betrayal. Bai Shu approves of the initiative and instructs Xie Biyan to continue monitoring Dai Hua. 49

Guarding the Ice and Fire Yin Yang Well

While Bai Shu and the other subordinates refined immortal herbs, Xie Biyan stood guard at the Ice and Fire Yin Yang Well. When Bai Shu fell into a deep sleep and became encased within an enormous evolving Green Lotus, Xie Biyan protected the site, contained Yue Guan's breakthrough pressure, and waited for Bai Shu to emerge safely. 52

Bai Shu's completed evolution released an immense life aura that washed away Xie Biyan's poison formation and triggered a beast tide throughout Sunset Forest. Xie Biyan ordered Yue Guan and Gui mei to defend the valley entrance, then restored the poison formation and helped drive off the remaining Spirit Beasts. 54 56

Blue Silver Forest Expedition

Xie Biyan accompanied Bai Shu to the Blue Silver Forest to seek the Blue Silver King for Bai Shu's third spirit ring. He maintained constant vigilance as the forest closed around them and stood ready to attack when the Blue Silver King reacted with hostility to the Blue Silver Emperor aura carried by Bai Shu. 62 63

When the Blue Silver Emperor attempted to use its root network and life essence transfers to evade repayment, Bai Shu ordered Xie Biyan to attack. Xie Biyan used his seventh Soul Skill, Bone-Eroding Heart Pierce, forcing the emperor to confront the danger its forest faced from his poison. He later guarded Bai Shu while Bai Shu absorbed the Blue Silver Emperor's hundred-thousand-year spirit ring and soul bone. 66 69

Later Service and Assignments

Bai Shu rewarded Xie Biyan with a ten-thousand-year soul bone in recognition of his service. 77

When Bai Shu needed to locate Dai Mubai, he dispatched Xie Biyan to Star Luo to investigate the situation while Bai Shu personally searched Suotuo City. 78
