Background / History

In his previous life, Sun Buxiao stayed overnight at an internet café, then fell into a cauldron of congee at a breakfast shop. He awakened on the Dou Qi Continent as a baby born with a soul-bound Porridge Bowl 1 2.

He grew up in the Chu Yun Empire with an absent father and a mother who practiced poison refinement. His mother accidentally killed herself through that practice when he was ten. After burying her, he began traveling with his bowl, teaching himself cultivation and scavenging equipment and Dou Techniques from corpses in the wilderness 1 10.

His reputation in Chu Yun was considerably darker than his conduct toward later companions. Xiao Yi Xian had heard that he slaughtered the small sect responsible for encouraging his mother to become a poison master, defeated a Da Dou Shi while still a Dou Shi, and retaliated against even minor offenses. These accounts initially made her afraid to approach him 27.

Retaining imperfect knowledge of Battle Through the Heavens, he traveled to Wutan City intending to befriend Xiao Yan after the latter’s fall from genius. Finding Xiao Yan still a One-Star Dou Zhe, he realized he had arrived three years too early and prioritized his own breakthrough instead 1.

Appearance

Sun Buxiao initially appears as a lean young man with black hair and a worn but clean white robe. His clothing gives him a refined air despite his frequently coarse behavior 1 27.

  • Porridge Bowl: Almost constantly carried in one hand; part of the recognizable description Xiao Yi Xian associates with his Chu Yun reputation 27.
  • White hair: His hair has become entirely white after his confrontation with Han Feng 78.
  • Scorpion tail: A later bodily feature capable of piercing opponents and fighting separately while he restrains another enemy 160.
  • Large wings: His Wind-Radiance Heaven-Splitting Wings are conspicuous enough for Mu Gu to recognize them as an Earth Tier Flying Dou Technique 222 224.
  • Hall of Souls attire: Receives an Elder’s robe and tokens after joining the organization; subsequently appears wearing a black hood 243 244.

Personality

Sun Buxiao is irreverent, vulgar, and deliberately provocative. He invents scandalous “unofficial histories,” spreads them through intermediaries, and uses his targets’ reactions to generate negative energy for cultivation. Han Feng becomes a particularly persistent target of this combination of mockery and calculated antagonism 4 35 76.

His confidence is tempered by an awareness of power disparities. As a young cultivator, he recognizes that talent offers little protection against someone capable of killing him. He postpones entering the Black-Corner Region until reaching Dou Ling and adopts a deferential manner before Hun Miesheng rather than pretending he can challenge a Dou Sheng 1 15 243.

Despite considering himself cold-blooded, he insists on retaining basic empathy. The sight of Qing Lin imprisoned for sale enrages him even before her identity matters to him. He becomes deeply protective of her and Xiao Yi Xian, while remaining ruthless toward enemies and subordinates who betray him 19 119 196.

He is also an experimental risk-taker. His willingness to force an incomplete Poison Pill procedure nearly destroys his body, and even his punishing fight with Mu Gu excites him as an opportunity to transform further. His poor reputation does not trouble him greatly: he attributes it to others’ fear and does not deny his violent methods 147 224 242.

Abilities & Skills

Porridge Bowl and Negative Energy

His soul-bound Porridge Bowl collects negative energy and produces millet porridge, which supports cultivation and strengthens the soul 2 4 11.

  • People strongly connected to fate produce more negative energy for the bowl, motivating his early approach to Xiao Yan 4.
  • Consuming this energy requires enduring negative emotions; prolonged use caused his acquired Woeful Poison Body 5 11.
  • One drop temporarily restored the sealed Hai Bodong to Dou Wang strength for approximately four hours 15.
  • Soul Solution directly strengthens the soul and stimulates Dou Qi. Spirit Realm advancement also allows solutions containing emotional poisons 45 135.
  • Millet porridge cannot fully replace Bodhi Body-Transforming Saliva: its protection of the heart is inadequate, and it does not provide the same cleansing effects 147.

Woeful Poison Body and Poison Pill

Unlike Xiao Yi Xian, Sun Buxiao was not born with his poison constitution. It developed as a side effect of consuming negative energy from childhood 5.

  • Cultivates by absorbing toxins, including poison he produces himself, though recycling his own poison is relatively inefficient 7.
  • Adapts to the Heavenblood Sickle Mantis’s venom before killing the fourth-order beast 7.
  • Releases poisonous gas and miasma for defense, area denial, and attacks; his poison can endanger bystanders as well as enemies 13 34 64.
  • Excessive toxin accumulation risks a fatal outbreak and widespread contamination 28 61 160.
  • Resolves the life-threatening accumulation by forming a seven-colored Poison Pill around a Heavenly Poison Scorpion Dragon Beast magic core 147 160.

Heavenly Flames

Flame Documented use
Netherworld Poison Flame Collected in the Millennium Poison Marsh, gradually attuned to his aura, and eventually devoured. Its heat and poison enable him to fight far above his cultivation rank 7 34 77 83.
Myriad Beast Spirit Flame Obtained as a weakened fire seed near a powerful beast skeleton. Later assists his Poison Pill formation and contains the wild Netherworld Poison Flame during Xiao Yi Xian’s absorption attempt 83 147 153.
Green Lotus Core Flame Uses a wisp alongside his other two flames to force toxins into the Poison Pill; this assistance does not establish him as the flame’s owner 145 147.
Sea Heart Flame Later keeps it in his bowl when preparing to use the Eagle Mountain Elder’s corpse and soul 183.
Fallen Heart Flame Conceals it inside his soul before Mu Gu arrives. It subsequently resonates with the Netherworld Poison Flame during his seclusion 222 246.
  • His original Netherworld Poison Flame remains within him when he helps Xiao Yi Xian absorb a separate wild flame of the same kind 152 153.
  • By the end of his month-long seclusion, he has fused and swallowed two Heavenly Flames, leaving a grayish-pink flame over his body before it withdraws inside him 246 247.

Kicking Techniques and Mobility

Sun Buxiao favors kicks rather than weapons, partly to keep one hand free for his bowl and retain the ability to escape 50.

Technique Applications and limits
Ink Poison Kick Profound Tier Low Grade attack. Breaks the Heavenblood Sickle Mantis’s sickle and defeats Mo Ran through his Dou Qi Armor 7 22 50.
Mist Shadow Step Movement technique used to close on Luo Bu during their fight 23.
Instant Shadow Cloud-Shattering Art Profound Tier Middle Grade movement technique taken from Zheng E 50.
Heavenly Poison Cloud-Treading Collapse Self-created axe kick capable of breaking combined Dou Wang attacks. Hai Bodong judges its force above Profound Tier, but early recoil can break Sun Buxiao’s leg, preventing a firm Earth Tier classification 64 67 69.
Purple Nightmare Piercing Thorn Earth Tier Low Grade poison technique. He chooses to practice it through his legs and combine it with his self-created kick 67 69.
Wind-Radiance Heaven-Splitting Wings Earth Tier Flying Dou Technique providing exceptional speed 222 224.
Three Thousand Lightning Movement Used alongside his wings for rapid travel through neighboring empires 245.

Body Tempering and Scorpion Tail

He experiments with condensing toxins and Dou Qi within his body rather than continually increasing poison intake 61.

  • Develops Poison-Pressure Body Tempering with Xiao Yi Xian, beginning with his legs 114 209.
  • Later withstands exchanges with Dou Zong-level opponents without the broken-leg problem that afflicted his earlier kicks 209.
  • Uses his scorpion tail to pierce Han Feng’s chest and engage other Dou Emperors while restraining him 160.
  • By Chapter 242, believes his physical strength alone is sufficient to beat a sixth-rank magical beast to death, but recognizes that his body still lags behind his soul 242.

Soul Perception and Soul Techniques

Negative energy strengthens his already unusual soul, supporting perception, concealment, and combat applications 11 41.

  • Locates Hai Bodong’s shop, recognizes Xiao Yan’s unusually powerful soul, and detects Earth Demon Old Ghost’s concealed soul aura 11 41 209.
  • Heart Demon Seed: Introduces an Inner Demon that can damage Dou Qi and soul strength or take over the victim’s personality. Overcoming it can instead bring benefits 77 135.
  • Soul Capture Net: Has one documented successful use against a Heavenly Poison Scorpion Dragon Beast. His later attempt cannot capture scattered emotional soul power or the power of heaven and earth 240.
  • His soul power initially forces Mu Gu’s back, but does not overcome the latter’s Dou Zun cultivation and experienced soul defenses 222 224.
  • Yao Lao identifies his early use of Spirit Realm soul power as crude; Sun Buxiao later seeks Hall of Souls knowledge to improve its application 137 240.

Poison Research and Auxiliary Arts

  • Medicinal-property reproduction: Helps Xiao Yi Xian investigate converting absorbed herbs’ properties into poison-body products; she produces blood reproducing fernwood grass’s medicinal components 124.
  • Strange Divine Limb-Reattachment Secret Art: Trades the art to Bai Ya for money, cultivation methods, and Dou Techniques 196.
  • Puppet refinement: Creates Heavenly Demon Puppets and two Lizardman Earth Demon Puppets; the latter are nearly destroyed during the Mu Gu battle 222 224.
  • Mosquito swarm techniques: Uses poisonous swarms to obstruct Medusa and evade coordinated attacks. Medusa’s lightning armor keeps the mosquitoes at bay, making them a distraction rather than a decisive attack 101 209.

Equipment / Weapons / Items

  • Porridge Bowl — Born with him and bound to his soul; cannot be taken away. Also holds Heavenly Flames and fire seeds 2 7 83.
  • Black Vein Poison Tome — His mother’s Profound/Mystic Tier Middle Grade poison cultivation method, used during his early self-taught career 10 137.
  • Dragon Chi Poison Canon — Earth Tier cultivation method that replaces his earlier tome 137.
  • Storage Rings — His original ring was scavenged from a corpse. Later acquires numerous high-grade rings filled with seized resources and uses rings to conceal allied souls 10 221 243.
  • Tou She Ancient God Jade fragment — Obtained from the Xiao Clan for three Profound Tier Dou Techniques; later surrendered to Hun Miesheng 51 52 243.
  • Hall of Souls Elder’s robe and tokens — Received with his appointment, together with resources and duties involving soul collection and the Myriad Soul Devouring Spirit Array 243 244.

Relationships

  • Xiao Yi Xian — Fellow Woeful Poison Body cultivator, research partner, and romantic partner. Their initially wary alliance develops through shared cultivation, Poison Pill research, and mutual protection; she also coordinates much of the Heavenly Poison Gate’s work in Black Seal City 28 30 124 153 156 214.
  • Qing Lin — Rescued girl, pupil, and close companion. He teaches her Qi Refining, arranges safer training opportunities, and threatens anyone who might bully her at the Heavenly Snake Mansion 19 22 140 196.
  • Xiao Yan — Fellow transmigrator and close friend, usually called “Little Yanzi.” Sun Buxiao supplies cultivation resources, helps him obtain the Green Lotus Core Flame, and maintains a friendship spanning nearly ten years 41 48 143 242.
  • Xiao Ding and Xiao Li — Traveling companions and mercenary allies. He helps them control Stone Desert City and asks Xiao Ding to gather poison-related methods before joining him in the Black-Corner Region 9 15 40 56.
  • Hai Bodong — Initially an adversarial bargaining partner, later an investor and ally. Tests Sun Buxiao’s self-created technique and oversees the Heavenly Poison Gate’s businesses 13 15 67 196.
  • Su Qian — Jia Nan Academy ally who recognizes his unusual talent and offers aid in battle. Sun Buxiao treats him informally but respects his goodwill 84 140 209.
  • Xiao Xun’er — Suspicious of his origins, knowledge, and closeness to Xiao Yan. Their conflict centers on the Ancient Jade fragment; he argues that removing it from the Xiao Clan protects Xiao Yan 40 52 143 187.
  • Han Feng — Major enemy targeted through fabricated rumors, Heavenly Flame combat, and a Heart Demon Seed 35 76 77 160.
  • Yuan Yi — First forced into negotiations after Sun Buxiao poisons his subordinates; later handles auctions and military responsibilities within the Heavenly Poison Gate 64 180 182.
  • Zi Yan — Traveling and operational companion who escorts captives, returns with him from Chu Yun, and accompanies the departure toward the Central Plains 221 222 247 248.
  • Yao Lao — Adviser on soul techniques and cultivation balance; concealed from Hun Miesheng when Sun Buxiao negotiates entry into the Hall of Souls 137 240 243.
  • Heavenly Fire Venerable / Yao Tianhuo — Sheltered soul whom Sun Buxiao helps resurrect using Earth Demon Old Ghost’s corpse; entrusted with guarding the Northwest during his planned absence 205 222 243.
  • Hun Miesheng — Hall of Souls master who appoints him an Elder, extracts a strand of his soul, and orders him to reach Dou Zun within ten years. Sun Buxiao privately intends to manipulate the organization 243.
