Background / History

Sun Yanbo trained under the same master as Lu Yangong and Lu Yanzhen. Their master entrusted him with the Overlord Sword, appointed Lu Yanzhen sect master, and taught Lu Yangong formation crafting, artifact refining, and pill refining. Sun regarded these inheritances as recognition of their different strengths rather than unfair favoritism 47.

He devoted himself to the Overlord Sword Strike within the Heavenly Demon Art, perfecting the technique with the support of the sect’s guardian spirit sword. Although Lu Yangong had cultivated for over a century longer, Sun’s focused sword training made him stronger in direct combat. His swordsmanship earned considerable renown for the Heavenly Demon Sect 47 48.

Appearance

Sun Yanbo is tall and burly, with the appearance of a man around fifty despite being centuries older. His bearing is fierce and domineering 46.

• Face: Thick eyebrows, large eyes, and a full beard flecked with gray 46.
• Clothing: A black robe, which becomes drenched in sweat after the poison takes effect 48.
• Signature weapon: A pitch-black greatsword carried on his back, nearly two meters long including its hilt 46.

Personality

Resolute and intensely devoted to swordsmanship, Sun places sect duty above personal ambition. He defends Lu Yanzhen’s authority on the grounds that the sect master is the most capable of their three fellow disciples. He also states that, had he been chosen to sacrifice his cultivation for the sect’s future, he would have considered it his duty 46 47 48.

His loyalty does not exclude compassion. After hearing Lu Yangong’s grievances, he offers to overlook their encounter—even at the cost of violating sect rules—if his senior brother abandons the Lin–Bai alliance. He also recognizes the suspicious nature of Lu Yangong’s battle tactics and holds strength in reserve rather than attacking recklessly 47 48.

Facing death, Sun remains defiant and resourceful: he refuses to let Lu Yangong kill him and claim his sword. His desperation later takes a darker turn when he attempts to seize Liu Xing’s body without first speaking to him 49 50.

Abilities & Skills

Heavenly Demon Overlord Sword Strike

Sun’s principal combat technique is an exceptionally fierce offensive art derived from the Heavenly Demon Art. With the Overlord Sword, he has brought it to a perfected level 48 49.

• Merges with his sword and transforms into black rainbow light to attack at tremendous speed 47.
• His clashes with Lu Yangong release shock waves that shatter space and force the Spirit-Devouring Beast’s divine sense to retreat 47.
• Outmatches Lu Yangong in sustained head-on combat, despite the latter’s longer cultivation history 48.
• Depends on spiritual energy; poisoning prevents him from replenishing the energy consumed during battle 49.

Sword-Based Escape Technique

At its pinnacle, the Heavenly Demon Overlord Sword Strike can shift from overwhelming offense to a powerful retreat technique. Lu Yangong does not know this capability exists 49.

• Requires the Overlord Sword and only a thread of spiritual energy to activate 49.
• Envelops Sun in the sword’s radiance and sends him fleeing as rainbow light faster than an ordinary rainbow-light transformation 49.
• Allows him to escape beyond Lu Yangong’s ability to pursue 49.
• Does not cure his poisoning or permit prolonged flight in his depleted condition 49.

Divine Sense and Concealment

Sun possesses powerful divine sense that remains intact even when his spiritual energy is nearly exhausted 45 50.

• Detects Liu Xing’s breathing and footsteps and locks onto him as he approaches 50.
• Examines Liu Xing’s body closely enough to confirm that he lacks an innate spiritual root 50.
• Does not provide the visual perception available through the Spirit-Devouring Beast’s divine sense 50.
• By drawing his spiritual energy inward, Sun conceals himself so thoroughly that he believes even another Nascent Soul cultivator should not detect him; the Spirit-Devouring Beast nevertheless tracks him 49 50.

Nascent Soul Release and Body Possession

With his original body deteriorating, Sun opens the Niwan Palace at the crown of his head and releases a nascent soul resembling a miniature version of himself, about a foot tall 50.

• Attempts to possess Liu Xing as a means of surviving the failure of his poisoned body 50.
• Normally considers a body without cultivation aptitude unsuitable, but accepts it because he has no alternative 50.
• Body possession has an exceedingly low success rate and numerous lingering complications; the attempt’s outcome remains unknown 50.

Equipment / Weapons / Items

• Overlord Sword — The Heavenly Demon Sect’s guardian spirit sword, inherited from Sun’s master. Its pitch-black blade supports both his perfected sword strikes and his concealed escape technique. Lu Yangong intends to seize it after Sun’s death 46 47 48 49.

Relationships

• Lu Yangong — Eldest senior brother and eventual enemy. After hundreds of years as fellow disciples, Sun pursues him for betraying the sect. Lu Yangong rejects an offer of mercy and poisons him during their duel 46 47 48.
• Lu Yanzhen — Fellow disciple and sect master. Sun defends his appointment and insists that decisions affecting the entire sect belong to him, not to an elder acting independently 46.
• Lu Xuanqing — Sect junior who addresses him as a grand martial uncle. When he confronts Lu Yangong, her sympathies lean toward Sun, though she cannot directly observe their battle 45.
• Liu Xing — Covert witness to Sun’s duel. Liu approaches him hoping to rescue Lu Xuanqing or leave Connors Star, but Sun instead attempts to possess his body 47 49 50.
• Unnamed master — Teacher who entrusted Sun with the Overlord Sword and appointed Lu Yanzhen to lead the sect 47.
