Lu Changfeng

Biodata

Power Progression

Background / History

In his previous life, Lu Changfeng was a top student at Capital Medical University, trained in both Chinese and Western medicine. After crossing into a martial Great Tang, he initially had no martial arts knowledge and did not know how to treat conditions involving true qi 1 40.

The original body's background was far humbler. According to Jinghong's investigation, he grew up alone and destitute in Shengping Ward. The itinerant physician Chen Yunsheng took him as an apprentice, and he spent ten years accompanying his master through Chang'an's streets. Neighbors remembered his medical abilities as mediocre, limited to ordinary colds and injuries 3.

Princess Taiping summoned him to treat Xue Chongyin after other physicians had failed. Facing execution if he could not help, he corrected Xue's neck injury with acupuncture and precise manual adjustment. Taiping then compelled him to become her residence's chief physician, assigning him quarters and an attendant whose duties also included surveillance 1 2.

His new position made ordinary medical knowledge insufficient. He sought martial medical texts and additional ways to prove his value, reasoning that dependence on a powerful patron's appreciation alone could not keep him alive 3 7.

His medical achievements, poetry, music, and transformed appearance eventually make his name famous throughout Chang'an. While public attention initially centers on his beauty and banquet performances, his rapid cultivation growth later establishes him as an exceptional martial figure as well 58 281.

Yuan Tiangang's examination provides an unusual indication of his otherworldly origin: his natal chart settles in none of the nine palaces, his qi lineage does not belong to this world, and his past and future are obscured by chaos and variables. Lu Changfeng is alarmed that Yuan can perceive something so close to his secret 113.

He becomes a newly initiated junior brother of Jiang Li in Medicine King Valley, but declines Jiang Li's invitation to relocate there, choosing to remain with Taiping for the time being 123. His later travels take him through Youzhou, Jiangnan, Mount Shu, Dragon-Slaying City, and Hongfang, where he acquires further medical inheritances, martial arts, and powerful allies 234 283 350 397 410 439.

After returning from Hongfang, he learns that Li Lingyue is pregnant with his child. His subsequent victory over He Chen on the Northern Frontier strengthens her political position, and she appoints him to the highest civil and military offices named in the provided context 454 474.

Appearance

Lu Changfeng's cultivation progressively changes his appearance, culminating in an extraordinarily beautiful, refined bearing that he often conceals with disguise techniques 12 27 28.

• After refining Shennong Qi: His previously slightly pale face acquires a warm jade-like luster, and his eyes become clear and bright 12.
• After Ice Skin, Jade Bones Art: His skin becomes exceptionally delicate, his bone structure refined, and his presence strongly alluring 27.
• Disguised appearance: He adjusts his bone structure and complexion to resemble a pleasant-looking but unremarkable young scholar 28.
• Clothing: Wears pale green official robes while working and a moon-white Wu Silk scholar's robe at Taiping's gathering 12 33.
• Public unveiling: When his disguise fails during the musical duel, guests mistake his beauty, bearing, and accomplishments for evidence of aristocratic upbringing 37 38.
• Private unveiling: Removes his disguise for Luo Qingge, who is visibly moved by his true appearance despite having expected exceptional beauty 97.
• Yan Zhaoming disguise: Uses a Rooted Skin Mask to take on a different, refined face appearing barely past twenty, paired with moon-white scholar's robes and the bearing of a traveling physician 391.
• Advanced body refinement: His skin briefly develops a jade-green sheen during the deeper transformation of his Shennong Qi, repeating nine times before the radiance merges into his body 347.

Personality

Lu Changfeng is composed under pressure. He maintains steady breathing and an unchanged expression even when surrounded by the corpses of unsuccessful physicians. His outward calm can also conceal intense anger: Taiping recognizes his nearly emotionless demeanor as a warning that he is genuinely displeased or harboring killing intent 1 36.

He values autonomy more than approval. He prefers practicing medicine and enjoying his own interests to pursuing courtly favor, and rejects becoming Taiping's male favorite because it would turn an exchange of useful services into dependence on her favors. He can yield when circumstances demand it without accepting that others have a right to control him 7 9 31 44.

His pragmatism has a ruthless side. He uses fear to establish authority, cripples attackers without hesitation, and kills Wei Linlang after she declares that she would try to murder him again. Nevertheless, the mutilated children in Mingyang's laboratory provoke genuine fury and a determination to help them 6 17 27 48 49.

During the laboratory investigation, his search for rewards becomes more morally troubling. He considers deliberately creating patients, then frames captured enemies as potential subjects for repeated medical and poison experiments rather than simply killing them 49 50.

His initial wish to avoid conflict gradually gives way to open defiance when caution repeatedly fails to prevent enemies from targeting him. He decides that, having done nothing wrong, he should not continually suppress his grievances to accommodate others 38 40.

Although initially uninterested in romance with Taiping or involvement in imperial succession struggles, he later becomes deeply attached to Li Lingyue and Luo Qingge. He refuses to endanger Luo Qingge by requiring her to accompany him to Hongfang or match his cultivation speed, and chooses to return to the Central Lands rather than accept a safer or more privileged life for himself alone 171 269 279 438.

His concern for loved ones does not wholly override calculation. While attempting to save Qing Dai, he recognizes that recklessly staking his life could fail to save her and only harm those who care for him. He adjusts his goal to surviving and buying time for reinforcements 303.

By the later political conflicts, he displays patience, strategic ruthlessness, and a clear sense of proportion. Zhao Lanjun comes to regard him as an exceptionally valuable ally and a terrifying enemy, capable of turning an escape investigation into an offensive against a rival faction 384.

Abilities & Skills

Noble Physician's Canon

The Noble Physician's Canon grants rewards for successful treatment, forming the foundation of Lu Changfeng's rapid growth 2 16 32 42.

• Immediate acquisition: Some rewards directly infuse mastery, internal energy, martial intent, or muscle memory rather than requiring conventional study 2 42.
• Varied rewards: Documented rewards include martial arts, scent expertise, poison and antidote, musical techniques, and items 2 6 16 32 49.
• Patient value: Its reference to “overall value” initially makes him wonder whether treating nobles produces better rewards; this is his inference, not an established rule 2.
• Deliberate exploitation: He actively seeks treatment opportunities and later considers extracting repeated value from enemies through injury, poisoning, and treatment 27 30 49 50.
• High-level treatment opportunities: The Canon identifies Yuan Tiangang's condition and offers the complete Four Absolutes of the Cosmic Sphere as a successful-treatment reward. Lu later receives the complete art 112 350.
• Later documented rewards: Receives the Nine Dragon Stone for treating Li Chongjun, the Heavenly Demon Zither for treating Sima Cheng, and the Snow-Drinking Saber for treating Li Lingyue 72 300 343.
• Cultivation planning: While in the late Fifth Realm, seeks to treat the Sixth Realm Lu Huanzhang in hopes of obtaining an internal cultivation reward rather than spending another year or two advancing conventionally 392.

Medical Expertise

His previous-life training allows him to recognize physical causes that local physicians misidentify, while later study equips him to treat martial injuries and poisons 1 4 7 21.

Nine Yin Manual

His first Canon reward provides complete mastery of the manual's internal cultivation, healing, acupoint sealing, palm, claw, fist, and defensive arts 2.

• Soul-Shifting Great Method: Combines qi, gaze, and voice to penetrate mental defenses and compel disclosure. He uses it on Cui Mingxuan after shock has weakened the man's resistance 6.
• Heart-Destroying Palm: Also rendered as Heart-Crushing Palm in combat; damages Yue Tao's heart meridians 2 17.
• Nine Yin White Bone Claw: Crushes limb joints and Gao Lu's ankle 17 18.
• Golden Bell Shield: Creates a bell-shaped defensive qi barrier. It survives Gao Lu's strike without being completely breached, but cannot prevent internal injury from the transmitted force and corrosion 18.
• Movement and body control: Uses uncanny evasions and bodily contraction to escape Gao Lu's ranged attacks 18.
• Cultivation limit: The manual does not provide the Heaven and Earth Bridge-opening method he needs to reach Xiantian 10.
• Bone-Shrinking Skill: Compresses his body enough to pass through an opening barely a foot across while investigating the subterranean route beneath West Mountain Island 287.

Shennong Glazed Glass Art

Lu Changfeng discovers this medical cultivation art hidden throughout Sun Simiao's handwritten Thousand Gold Prescriptions. Its effectiveness depends heavily on medical understanding 10 11 23.

• Shennong Qi: Healing-oriented qi that purifies internal toxins, nourishes the body, and neutralizes dangerous poisons 12 42.
• Glazed glass body: Cleanses flesh, marrow, and acquired impurities while strengthening the body 21 23.
• Breakthrough method: Supplies the means to open the Heaven and Earth Bridges 10 21.
• Initially incomplete inheritance: The missing visualization diagram prevents him from condensing true intent and advancing to Grandmaster through the version he initially obtains. He later reaches Grandmaster through his expanded cultivation resources and obtains a visualization scroll from Jiang Li that can benefit his Shennong Qi 12 106 123.
• Higher potential: The third realm opens the body's medicine vault to absorb medicinal properties. The proposed fourth realm promises regeneration and reattachment of severed limbs, but even its creator did not attain it. Lu later reaches the human golden elixir level associated with limb regeneration and bodily fragrance 23 347.
• Five-Organ Medicine-Storing Method: Stores medicinal essence in appropriate meridians and acupoints, allowing medicinal power to nourish his qi and support breakthroughs 59.
• Rare medicinal refinement: Uses the Seven-Colored Purple Vine and Nine-Springs Jade-Leaf Bloodflower to bring his glazed glass body near full mastery and transform his qi 140.
• Pure vitality: Further refinement with nine-jointed sweet flag changes his qi beyond ordinary healing energy into a force described as pure vitality 347.
• Advanced medicine storage: Directs the dual properties of nine hells mystic lotus into the Lung Meridian's Deficient Mound and Kidney Meridian's Shining Sea acupoints, where the medicinal power interacts with Primordial Beginning True Qi 436.
• Dangerous desirability: Taiping warns that others might enslave him as a medicine slave. Zhang Lingjun later identifies his xiantian dao body, fortune, and comprehension as ideal ingredients for a Human Origin Great Pill intended to transform Li Chongfu 23 272.

Scent Recognition and Fragrance Craft

His scent-related reward grants extraordinarily precise smell and instinctive expertise in fragrance properties, extraction, concentration, and combinations 6 8.

• Distinguishes individual medicinal ingredients and separates layered scents 8.
• Traces scents to their sources and estimates how long they have lingered 8.
• Combines this expertise with physics and chemistry to build a simple distillation apparatus, produce high-proof alcohol, and create jasmine Fragrance Dew 8.
• Offers Taiping the production methods and instructions for seven additional fragrances in exchange for medical-library access 8.
• His tracking becomes a recognized threat to enemies: Xu Xiao concludes that Lu tracked Siming by scent and supplies Ink Flood Dragon Saliva to mask their odors 384.

Photographic Memory

Lu Changfeng memorizes medical texts and answers Zhang Shouzhuo's tests on prescriptions and acupuncture fluently 11.

• Retains the hidden Shennong cultivation method without revealing its location 10 11.
• Uses rapid study of medical manuscripts to expand his treatment knowledge 21.
• His exceptional comprehension later allows him to master nearly every cultivation method in the Longbo forbidden grounds within half a month 410.

Ice Skin, Jade Bones Art

A max-level life-nourishing art transforms his physique and appearance while making qi circulate more smoothly 27.

• Strengthens and widens his meridians 27.
• Establishes the foundation of a xiantian dao body and grants a natural affinity with the opposite sex 27.
• Makes his appearance conspicuous enough that he uses disguise techniques to suppress its effects 28 33.
• His later xiantian dao body becomes a motive for Zhang Lingjun's attempt to use him as human medicinal material 272.

Thousand-Face Disguise Art

Lu Changfeng learns this art to change his appearance and move through crowds without being recognized by his enemies 26.

• Adjusts bone structure, complexion, and visible refinement 28.
• Successfully passes through increased patrols as an ordinary scholar while concealing his aura 28.
• Requires fine control and practice; his disguise fails during the intense musical duel with Wang Xiao 26 37.
• Supports his covert identity as the merchant Yun Fan during the Youzhou investigation 221 234.
• Later employs a Rooted Skin Mask for the Yan Zhaoming identity. The treated human-skin mask fuses with his skin and cannot be peeled away unless dissolved with true qi 391.

Poetry and the Six Methods of the Guzheng

He presents celebrated poems from his previous world's literature and receives the Six Methods of the Guzheng after treating Luo Qingge 30 32 36.

• Uses Li He's “Dreaming of Heaven” to impress Luo Qingge and the Moon-Gathering Tower's guests 30.
• Overwhelms Taiping's poetry contest with “Qingping Tune” 36.
• Performs “Ambush from Ten Sides” on the Lovesick Zither, countering Wang Xiao's sonic attack, injuring him, and breaking his Jade Flute 37.
• His victory is attributed to music that commands the soul rather than superiority in internal cultivation 37.
• Suspects Peng Junqing's guqin performance is intended to control the Hook-Tailed Serpent and attack Li Dan, and accepts a joint performance to prepare a countermeasure 191.
• Soul-Seizing Tune: Uses the Heavenly Demon Zither to magnify Liu Ciyuan's murderous impulses, disrupt his precision, and drive him toward qi deviation while buying time for Li Lingyue's arrival 306.

A-Fei's Swift Sword

The Canon directly imparts this sword technique after he cures Mu Lan 42.

• Focuses on instantaneous explosive force and absolute speed 42.
• Brands an efficient draw–thrust–sheathe sequence into his muscle memory, eliminating redundant movement for a single lethal strike 42.
• No combat use explicitly identified as this particular technique is documented in the supplied passages 42.

Gu Studies

He studies gu arts for Taiping's poison problem and the investigation of the Blood Tai Sui 23 40.

• Favors refining gu over spellcasting because his initial-Xiantian spiritual sense is too weak for powerful spells 41.
• Considers combining gu with pufferfish poison to make killings harder to trace 41.
• Recognizes the burden of nurturing gu with the practitioner's vital and heart blood; he has not completed a refinement during his initial studies 41.
• Blazing Wind Gu: With Lan Die'er's instruction, completes the initial refinement of the Crimson Flame Wyrm into Blazing Wind Gu 78.
• Cultivation upkeep: Lan Die'er later supplies poisonous creatures for the Crimson Flame Wyrm 140.
• Interrogation: Uses Blazing Wind Gu to inflict agonizing pain on the captured Pei Zhennan after he refuses to disclose information about Great Vehicle Sect activity 240.

Threefold Origin-Returning Qi and the Three Supreme Arts

Lu Changfeng fully masters Threefold Origin-Returning Qi, which combines wind, cloud, and frost and possesses qualities useful for both combat and medicine 75 76.

• Three Supreme Arts: Employs Wind God Leg, Cloud-Displacing Palm, and Heavenly Frost Fist, combining their refined qi into concentrated attacks 76 182.
• Medical applications: Its dissolving power can seal acupoints, stop bleeding, remove dead flesh, and promote new tissue 75.
• Explosive defense: Releases its full power at close range to repel a half-human, half-snake attacker and crack its scales 89.
• Condensed attack: Compresses the three energies into a crystal-clear sphere containing wind vortices, cloud currents, and frost 89 182.
• Origin-Returning Qi Barrier: Forms a large spherical defense capable of temporarily resisting simultaneous attacks from ten experts, including two Fourth Realm Grandmasters, though sustaining it imposes a substantial burden 228.

Heaven and Earth Great Shift

This art mobilizes the latent strength of his prior cultivation and grants exceptional perception and redirection of force 94.

• Increases his physical strength severalfold when first acquired 94.
• Establishes an awareness field that registers dust, flame movement, and faint underground vibrations 94.
• Redirects the tremendous momentum of Mad Weituo's Mind-Bewildering Pestle, sending it into the ground rather than taking the strike directly 107.

Yin-Yang Arts, Formations, and Spellcraft

His Yin-Yang Arts use his body as an array core, Divine Sense to command qi, and circulating yin, yang, and Five Elements power to produce effects around him 106.

• Five Elements array: Establishes an invisible array through Grandmaster-level qi and Divine Sense 106.
• Eight Formations Diagram: Becomes part of his broader martial foundation and his preparations for dangerous expeditions 279 299.
• Flying Dragon and Coiling Snake Formations: Enhance his control over water and allow him to fight freely in Kunming Pool 263.

• Three Powers Sword Formation: Coordinates three flying swords into a formation combining sword qi with ice, fire, and baleful energy 270.
• Talisman script and Divine Sense: His proficiency makes him particularly suited to confronting divine-soul possession, a problem conventional swordsmanship cannot readily solve 365.
• Eight-Direction Barrier: Uses it to confine Luo Qingge and Bai Qianqian within Snow Listening Tower during their confrontation over Wang Jingxian 474.

Ghost Valley Inheritance

The Treatise on All Under Heaven gives Lu Changfeng Vertical and Horizontal True Qi, advanced close-combat methods, and the ability to draw upon natural forces 186 187.

• Divine Command of the Six Forces: Uses true qi as a guide and Divine Sense as a bridge to perceive and command yin, yang, wind, rain, darkness, and light 186.
• Opening-and-Closing Hands: Alternates attack and concealment, opening and defense, with precise force guidance through his hands and fingers 187 228.
• Force redirection: Diverts powerful palm strikes, disperses leg attacks, and incorporates an opponent's force into his own responses 228 303.
• Six Forces Lock: A talisman-based ultimate move of Divine Command of the Six Forces, used to trap the young Flood Dragon 264.
• Sustained combat: Draws on the Six Qi and Eight Circulation Energies of heaven and earth to replenish himself during prolonged fighting 304.

Expanded Martial Inheritances

His later acquisitions and training encompass multiple weapons, bodily disciplines, and spiritual arts 166 171 299 350 409 410.

• Phoenix Dance Nine Heavens: An elusive movement technique used to evade attacks in confined spaces; combining it with wind power greatly increases his speed 225 230.
• Tathagata Divine Palm: Receives nine palm forms corresponding to Buddhist spiritual conceptions, with supreme yang power capable of suppressing dark and evil killing intent 171.
• Spear mastery: Demonstrates profound spear technique while wielding the Horizon Spear alongside the Wind-Raising Formation, surprising Xue Chongjian and Qing Dai 166.

• Five-Thunder Dissolution Hand: Destroys Liu Xuance's dantian, true qi, and dragon essence. Later uses Five Elements lightning to dissolve metal attacks 343 383.
• Indestructible Golden Body: Provides advanced physical protection alongside the regenerative support of Shennong Glazed Glass Art 383.
• Dragon God Art: A nine-level, supreme-hardness and yang art allowing illusory dragon transformation, flight, attacks, poison expulsion, healing, object seizure, and bodily protection 409.
• Yu King's Axe Technique: Masters the Longbo-associated axe art and demonstrates it with an axe condensed from true qi 410.

• Flame Dance Whirlwind Sword Art: Kills most of the Qinyuan swarm pursuing Yun Lou 438.
• Yin-yang dual cultivation: Demonstrates expertise during his extended relationship with Ji Xian 453.

Four Absolutes of the Cosmic Sphere

Yuan Tiangang's treatment quest offers the complete version of this supreme body-tempering art, which Lu Changfeng eventually receives 112 350.

• Refines the natural forces of heaven, earth, sun, and moon into vital essence 346.
• Uses sun and moon as intermediaries for the opposing powers of wind, thunder, fire, and rain, creating complementary yin-yang forces that renew themselves 346.
• Forms four streams of vital essence when mastering its foundations 350.

Astrology, Divination, and Strategic Insight

Lu Changfeng studies the True Explanation of Purple Tenuity Astrology and learns to use starlight for insight and simple divination 350.

• Writes a memorial opposing the cession of the Nine Bends of Hexi to Tubo on strategic-defense grounds 372.

• Go: Defeats Yun Lou by one and a half points, drawing praise for an upright opening, deep middle game, and watertight endgame 425.

Integration of Martial Arts

The Imperial Seal briefly grants Lu Changfeng Divine Wandering in the Great Ruins, enabling him to perceive how his many inheritances can form a single martial system 299 305.

The yin-yang principles of Opening-and-Closing Hands merge into his swordsmanship, Tathagata Divine Palm's force enters his punches and kicks, and Heavenly Crippled Divine Skill informs his footwork. Incorporating force-dispersing methods into Supreme Sword Dao greatly increases his sword techniques' effectiveness, though overwhelming opponents such as Liu Ciyuan can still place him in mortal danger 299 305.

Equipment / Weapons / Items

• Wind-Raising Sword — One of the Shu Eight Swords and formerly Marquis Wu's weapon. Although initially a fourth-tier renowned sword, its spirituality exceeds that of an ordinary spirit weapon.

Relationships

• Princess Taiping / Li Lingyue — Patron and initially compulsory employer. She rewards his usefulness, monitors him, and publicly names him her guest adviser. Her personal interest grows, but he initially rejects dependence as a male favorite and resists her control 2 8 33 44. Their relationship later becomes openly intimate; she declares that he belongs to her, while he avoids implicating her in retaliation against her nephew Li Chongfu. She rescues him from Liu Ciyuan, kisses him after he treats her, and later becomes pregnant with his child. Once empowered to govern on the emperor's behalf, she appoints him Tong Zhongshu Menxia Pingzhangshi and Supreme General of the Celestial Strategy 264 269 306 343 454 474.
• Qing Dai — Attendant, protector, and initially an instrument of surveillance. She shields him from Zhang Shouzhuo, helps him escape questioning, fights beside him, and supports him after exhausting treatments 2 4 11 18 22. She continues accompanying his travels, and her encirclement at the Riverside Inn prompts him to hurry to her rescue despite the danger 179 225 300 303.
• Jinghong — Taiping's senior official and intermediary. Arranges his duties, escorts him on urgent cases, identifies Gao Lu, and reports the Wind-Raising Sword's awakening 2 16 19 40.

• Chen Yunsheng — The original body's medical master, who took him in as a child apprentice 3.

• Gao Jian — Jealous rival whose resentment grows after Lu gains Taiping's trust. Plans his death; the exposure of Gao Lu leads to Gao Jian losing his posts and being confined 8 9 19. Later accepts an offer of help from Yin Xuanhe, the Great Vehicle Sect's Netherworld Doctor, while continuing to blame Lu for his lost favor. Taiping subsequently places the judgment of Gao's participating confidants in Lu's hands 78 94.
• Su Bonian — Prisoner whose Avici Seal Lu removes, earning profound gratitude and advancing Taiping's investigation of the Two Zhangs' treasures 19 22 40.
• Wei Linlang — Great Vehicle Sect holy maiden who impersonates Qing Dai to capture him. He interrogates and kills her after she vows to try again 25 27.
• Luo Qingge — Musician and patient who initially regards him as a kindred spirit. She admires his independence and attempts to shield him from Yan Mingxiao's questioning 30 31 32. Their relationship develops into love dating from his Xiantian period. He rushes to help when she is threatened, later works with her bird-scouting ability, and gives her the Deathless Elixir upon returning from Hongfang. She accepts Bai Qianqian and informs him of Li Lingyue's pregnancy 140 209 279 438 454.
• Yan Mingxiao — Chang'an Constable investigating Zhang Shouzhuo's death. His refusal to submit to questioning without credentials and a warrant strengthens her suspicion 31. Later grants him several days to investigate a mysterious adept, requiring him to share any discoveries 209.
• Zhang Shu — Friendly acquaintance who introduces him to banquet society and warns him about Wang Xiao's lethal sonic art 33 34.
• Wang Xiao — Rival aligned with Princess Anle and Empress Wei; defeated by Lu in the musical duel 34 37.
• Princess Anle — Initially challenges him to embarrass Taiping, then becomes interested in recruiting him away from her aunt 36 38. Her repeated advances fail, and her attraction develops alongside resentment over his relationship with Taiping. She and Fifth Ying'er view his pretended injury at Kunming Pool as an opportunity 262 264.
• True Person Mingyang — Enemy exposed through the Blood Tai Sui investigation. Lu condemns his experiments on children and vows to make him suffer if captured 47 48 49 50. The real Mingyang later attacks him as a slaughter-driven Soldier with Great Grandmaster-level power 52.
• Lan Die'er — Gu practitioner who teaches him to refine the Crimson Flame Wyrm into Blazing Wind Gu and later supplies poisonous creatures for its upkeep 78 140.
• Yuan Tiangang — Unfathomable elder and high-value patient whose Dark-Mystery True Qi initially exceeds Lu's ability to handle. Gives him Snow Robe, recognizes anomalies in his natal chart, and later praises his actions at Li Mountain 112 113 345 346.
• Ye Fashan — Senior master whose visualization diagram Lu studies. After treating him, Lu describes himself as Ye's successor and credits him with helping hold back the Ancestral Dragon 112 343.
• Jiang Li — Medicine King Valley senior brother who permits him to keep a visualization scroll, offers the valley's protection, and assures him that the sect will stand behind him despite his decision to remain with Taiping 123.
• Li Chongjun — Crown prince and patient who offers him a position in the Eastern Palace. Lu declines; Li Chongjun subsequently fears that his ability to suppress Taiping's gu poison will undermine a larger scheme 72.
• Li Dan — Imperial figure whom Lu repeatedly helps protect from assassination and poisoning. Lu's warning about frontier danger is conveyed to him, and he cautions Li Longji against excessive entanglement with Taiping's trusted adviser 191 206 273 386.
• Li Longji — Imperial ally whose admiration for Lu's abilities is tempered by concern that Lu greatly strengthens Taiping's faction. Lu entrusts him with the Imperial Seal and sends him to seek reinforcements; later treats his injuries after the Ancestral Dragon conflict 269 300 343. After Lu returns from Hongfang, Li Longji is alarmed by his survival and the powerful fox immortal accompanying him 456.
• Zhao Lanjun — Powerful ally in Taiping's service. Assists in crises and later recognizes Lu's political methods, patience, and ruthlessness as assets comparable to an army 46 52 343 384.
