Background

Xuan Du was born among the Human Race and later entered Kunlun Mountain as Laozi's disciple. He became the Ren Sect's senior disciple and was entrusted as the person Xuan Dan should seek when Laozi and the other Saints were absent 15 18.

He remained closely tied to his origins. During a journey with Xuan Dan, he returned to the Human Race for the first time since joining Kunlun Mountain, preached the Dao to talented humans, and maintained ties with leaders such as Suiren Shi 18 20 170. When the War of Ten Thousand Races threatened humanity, he returned to support his people and spent much of his time away from Kunlun Mountain 318.

Appearance

Xuan Du is ordinarily described as having an honest, simple bearing, a spring-like smile, and a calm demeanor 17. Xuan Dan's pills repeatedly alter this appearance.

• The Tianxin Pill transformed him into a childlike female form with a child's voice after he achieved enlightenment in the Profound Mirror Divine Eye 4.
• Following the Divine Root Pill incident, he developed a high-pitched voice and an affected “eunuch persona,” which he found deeply humiliating 562 564.
• After becoming a Saint, he again discovered that he had become a loli and dispersed his Saintly phantom rather than reveal himself publicly 616.

Personality

Xuan Du is generally dependable, cautious, and responsible. He takes his role as senior brother seriously, guides Xuan Dan, returns to aid the Human Race in times of need, and accepts unpleasant responsibilities when others avoid them 15 318 545.

His patience is most tested by Xuan Dan. He is wary of his junior brother's pills after personally enduring their side effects, yet repeatedly accepts them out of trust, duty, or concern for Xuan Dan's feelings 18 295 545. He can also be teasing and mischievous, such as laughing at Xuan Dan after forcing a Breakthrough Pill on him during their tournament duel 66.

Defeat and public embarrassment affect him strongly. After losing to Xuan Dan through Poison Miasma, he sought Laozi for comfort; later, his transformations and accidental public displays repeatedly leave him desperate to preserve his dignity 67 549 616.

Abilities & Skills

Golden Elixir Great Dao

Xuan Du cultivates the Golden Elixir Great Dao and is particularly vulnerable to techniques that directly suppress Golden Elixir-based Magic Power.

• His Golden Elixir cultivation gave him a clear advantage over Xuan Dan in their initial exchanges during the Grand Competition 65.
• Xuan Dan's Poison Miasma specifically interfered with his ability to mobilize the primal power within his Golden Elixir 65 66.
• He teaches the Golden Elixir Great Dao through detailed instruction on refining essence, energy, and spirit into an internal Golden Elixir 433.

Profound Mirror Divine Eye

After consuming a Tianxin Pill, Xuan Du spent a hundred years attaining enlightenment in the Profound Mirror Divine Eye.

• Its completion manifested as two golden beams shooting into the sky and resonating with the Dao 4.
• The breakthrough ended a bottleneck that had persisted for thirty thousand years 4.

Pill Dao and Teaching

Xuan Du is regarded as a talented Pill Dao practitioner and is especially effective as an instructor, though his own performance in a formal alchemy contest was poor.

• He scored three out of ten in an alchemy competition, leaving him dejected despite his reputation 216.
• He offered to guide Shen Nong on the medical path and taught him cultivation systematically 438.
• His explanations of the Golden Elixir Great Dao are thorough, and Shen Nong's questions are answered directly 433.

Combat Techniques

Xuan Du is an experienced combatant with both fire-based techniques and defensive treasures.

• Samadhi True Fire — Used to restrict Xuan Dan's movement during their Grand Competition match 65.
• Eight Trigrams Purple Gold Furnace — Absorbed Xuan Dan's Blazing Heaven Fiery Flame during their duel 66.
• Dragon-Headed Flat Crutch — His primary close-combat weapon; he later used it to strike Saint Tian Yu's true spirit 66 549.
• Physical combat — After taking a Dragon Elephant Pill, he relied on enhanced physical strength to crush Grand Unity Golden Immortal puppets inside the Spirit-Severing Mist 547 548.

Spirit Deprivation Mist

Xuan Du gained the ability to summon the Spirit Deprivation Mist after refining Saint Tian Yu's true spirit and absorbing the Saint's residual memories.

• The mist seals Magic Power and forces intruders to rely on physical-body cultivation 547.
• He obtained the technique after discovering that Saint Tian Yu's inheritance trial was an attempted possession scheme 549.

Saint Realm

Xuan Du proved the Dao with the help of a Tianxin Pill refined by Saint Xuan Dan.

• His breakthrough drew together Heavenly Dao power, Human Race Luck, Great Dao runes, and Saintly might 615 616.
• He became the first Saint of the Pangu Primordial Era 616.
• His ascension was concealed when he dispersed his own Saintly phantom to hide his transformed appearance 616.

Equipment / Items

• Dragon-Headed Flat Crutch — Close-combat weapon used against Xuan Dan and Saint Tian Yu 66 549.
• Eight Trigrams Purple Gold Furnace — Furnace capable of absorbing hostile flames 66.
• Tianxin Pill — Xuan Dan's comprehension-enhancing pill; helped Xuan Du attain the Profound Mirror Divine Eye and later prove the Dao, but repeatedly transformed him into a loli 4 615 616.
• Clear Toxin Pill — Used to purge Xuan Dan's Poison Miasma after their tournament match 67.
• Dragon Elephant Pill — Temporarily enhanced his physical body enough to pass the Spirit-Severing Mist's trials 547.

Relationships

• Laozi — Master. Laozi entrusts Xuan Du with overseeing Xuan Dan when necessary and comforts him after his tournament defeat 15 67.
• Xuan Dan — Junior brother. Their relationship combines mentorship, affection, rivalry, and repeated pill-related disasters; Xuan Dan prioritizes Xuan Du whenever he refines a new pill 18 506 614.
• Shen Nong — Student. Xuan Du teaches him the Golden Elixir Great Dao and assists in guiding him after he becomes Human Emperor 433 444.
• Fuxi — Fellow guide of the Human Race. Xuan Du identifies Fuxi as the former Demon Court Xi Huang and helps arrange guidance for the Human Emperor 318 432.
• Duobao — Fellow senior disciple and friend. Duobao consoles him after his poor alchemy score, though Xuan Du finds the consolation aggravating 216.
• Xuanyuan — Human Emperor and accidental travel companion. The two became stranded in the Demonic Primordial Era and eventually returned together 561 564.
• Saint Tian Yu / Heavenly Feather Saint — Deceased Saint whose purported inheritance was actually an attempted possession. Xuan Du defeated and refined his true spirit 547 549.

Story Role / Major Arcs

Early cultivation and Tianxin Pill incident

Xuan Du emerged from seclusion after sensing Xuan Dan's alchemy. He accepted Xuan Dan's Tianxin Pills, achieved enlightenment in the Profound Mirror Divine Eye, and discovered that the pill had transformed him into a childlike female form 3 4.

Human Race journey

He brought Xuan Dan to the Human Race, returned to his original people, preached the Dao to promising humans, and remained alert to instability within the Three Sects 18 19 20.

Three Sects Grand Competition

Xuan Du fought Xuan Dan in the tournament and dominated the early stages through superior cultivation and Samadhi True Fire. Xuan Dan ultimately poisoned him through Blazing Heaven Fiery Flame laced with Poison Miasma, forcing Xuan Du to concede defeat after using a Clear Toxin Pill to purge the poison 65 67.

Human Race mentor

After the Human Race produced Fuxi, Xuan Du returned to Kunlun Mountain to enlist Xuan Dan's help. He later became Shen Nong's principal instructor, teaching him the Golden Elixir Great Dao and helping oversee Human Race affairs 318 433 444.

Divine Root Pill and Heavenly Feather inheritance

Xuan Du reluctantly tested Xuan Dan's Divine Root Pill, which enhanced his foundation but sent him into spatial turbulence. In an ancient battlefield, he passed the Spirit-Severing Mist, defeated its puppets with the aid of a Dragon Elephant Pill, and destroyed Saint Tian Yu's true spirit after learning the “inheritance” was a possession trap 545 547 549.

Saint ascension

When Xuan Dan became a Saint, he kept his promise to prioritize Xuan Du with the first Tianxin Pill he refined afterward. The pill enabled Xuan Du to prove the Dao and become a Saint, though it also completed the recurring cycle of transforming him into a loli 607 614 616.

Trivia

• Xuan Du's first Tianxin Pill transformation occurred immediately after he celebrated ending a thirty-thousand-year bottleneck 4.
• Despite frequently distrusting Xuan Dan's pills, he remains one of Xuan Dan's most consistent test subjects 295 545.
• He once described himself as the “Ninethousand Years Old of Pangu Primordial Era” while mocking the puppets in the Spirit-Severing Mist 547.
• His Saint ascension was the first known case of someone actively dispersing their own Saintly phantom out of embarrassment 616.
