Background

Old Yao spent three years hidden within a ring while drawing Xiao Yan's Dou Qi. After Xiao Yan discovers him, he manifests as a silver-haired soul phantom and is confronted over the stolen cultivation. Intrigued by Xiao Yan's Fire Kirin physique and abnormal cultivation speed, he recognizes him as an ideal candidate for Fen Jue and offers Shadowless Step and Eight Extremes Collapse as an apology. 2

He later becomes Xiao Yan's teacher, presenting him with a choice between the Earth-tier Intermediate Crimson Sun Art and the low-level Yellow-tier Flame Mantra. Xiao Yan chooses Flame Mantra without hesitation. 4

Before taking Xiao Yan as his disciple, Old Yao had treated Han Feng as his own son. Han Feng's betrayal ended that bond; when they meet again, Old Yao regards him with detached indifference and leaves his punishment to Xiao Yan. 94

Old Yao also bears a painful history with the Yao Clan, having been expelled from it in the past. Despite those grievances, he helps save Yao Dan during the Hall of Souls' assault on the Yao Clan, then chooses to leave after concluding that the clan must bear the consequences of its own actions. 171 179

Appearance

Before his resurrection, Old Yao appears as an ethereal elderly phantom with silver hair flowing without wind. After receiving a new body, he appears as a refined, authoritative middle-aged man with ink-black hair. 2 147

• Soul form condenses from the Bone Flame Ring. 14 71
• His spectral body becomes increasingly solid as Xiao Yan repairs his soul. 35
• His resurrected body bears faintly glowing runes, a manifestation of condensed power. 147
• Seven-colored fire lotuses bloom beneath his feet when he moves after his resurrection. 147

Personality

Old Yao is blunt, temperamental, and exacting toward Xiao Yan. He harshly rebukes reckless decisions—especially dangerous pill consumption, premature Strange Fire absorption, and distractions during alchemy—but his anger consistently comes from concern for his disciple's safety. 14 50 71

He takes obvious pride in Xiao Yan's extraordinary talent, gradually embracing him as his precious disciple. Xiao Yan's achievements repeatedly astonish him, from refining medicine through his own body to reaching the Emperor Realm Soul at an unprecedented pace. 50 170

Although he is hardened by Han Feng's betrayal and the Yao Clan's treatment of him, Old Yao remains capable of compassion. He chooses to aid the Yao Clan against the Hall of Souls despite their past wrongdoing. 94 179
