Background / History

Yao Chen was born into a humble branch of the Yao Clan. After losing his father young, he endured scorn, was framed during the Yao Conference, and expelled from the clan despite his talent. Through hardship and fortuitous encounters, he rose from an ordinary cultivator with poor bloodline and limited resources to become the foremost Medicine Master of the Central Continent. 289

Known as the Medicine Venerable, Yao Chen became an eighth-grade Medicine Master and a Nine-Revolutions Dou Zun. His career ended in betrayal when his disciple Han Feng collaborated with the Soul Hall and caused Yao Chen's death; Yao Chen survived only as a soul within the Bone Flame Ring. 26 238 241

After awakening in the ring, Yao Chen accepted Xiao Yan as his disciple and began guiding him on the path of cultivation and medicine refinement. 14 29 He later formed a cooperative relationship with Little Doctor Immortal, providing knowledge on the Calamity Poison Body, lending her soul power in battle, and entrusting her with alchemical and cultivation legacies. 12 115

Yao Chen eventually confronted Han Feng in Medicine Emperor City. Coldly ending their master-disciple relationship, he destroyed Han Feng's cultivation and spiritual foundation before killing him with the Bone Spirit Cold Flame. 241 242

During the battle against the Outer Realm Heavenly Demon, Yao Chen burned soul power to strengthen Little Doctor Immortal to peak Dou Zong-level strength for a brief period. The expenditure left him in a deep sleep expected to last months even with soul-restoring medicine. 351 353

Appearance

Medicine Elder commonly appears as a white-robed, white-haired, handsome man rather than an aged elder.

• Flowing white robes and long white or silver-white hair. 289
• Handsome face; openly praises his own appearance. 289
• Usually manifests in soul form or resides within a Storage Ring/Bone Flame Ring. 103 240
• When possessing Xiao Yan, he changes Xiao Yan's eyes pale silver-white and turns his hair long and white. 73 168

Personality

Yao Chen is experienced, perceptive, and pragmatic. He supports Little Doctor Immortal's decision to seize resources, believing that strength and self-preservation are essential in the cultivation world. 18 He is also patient with Xiao Yan, encouraging him through difficult training and repeatedly protecting him in crises. 84 168

Despite his status and experience, he has a shamelessly playful side: he eagerly claims valuable alchemy furnaces, calls himself handsome, and is teased by Little Doctor Immortal as a “shameless old man.” 19 289

Han Feng's betrayal remains his deepest wound. Yao Chen's normally relaxed demeanor turns sharply hostile whenever Han Feng or the Soul Hall is involved, though he retains enough restraint to judge Han Feng personally rather than acting blindly. 28 238 241
