Background

Before accepting Zhong Lin, Yin Daoyan was already the Hall Master of Hundred Herbs Hall, an elder of the Sword Cauldron Sect, and a renowned second-rank martial artist. He was preparing the Dao Yan Materia Medica, a major medical work for which he sought Zhong Lin's illustrations of medicinal materials. 64

His lineage emphasized “talent and fortune” rather than fierce competition. Though many people sought to become his disciple, he initially had no formal successor and chose to observe Zhong Lin before making a decision. 64 67

Appearance

Yin Daoyan initially appeared as an elderly man with white hair and a white beard. 69 After breaking through to the Innate Realm, his hair became completely black and his appearance reverted to that of a middle-aged man. 263

• Previously carried the appearance and bearing of an aged master physician. 69
• Looked markedly younger following his Innate Realm breakthrough. 263
• Is associated with a red sword light when intervening in combat. 123

Personality

Yin Daoyan is discerning and unorthodox in selecting disciples, valuing natural talent and providence over pedigree. His delight at Zhong Lin's aptitude is genuine and unconcealed; he repeatedly praises him as a future pillar of the Sword Cauldron Sect. 67 78 124

He is also protective of his disciples. When Zhong Lin was pursued and injured, Yin Daoyan's first concern was confirming his safety, and he vowed vengeance against the attacker if Zhong Lin had been seriously harmed. 114

Despite his status, he is playful and sharp-tongued with close friends such as Jing Tang and Lian Shan Elder. He is proud of his pill-refining accomplishments, enjoys teasing others, and is a poor loser at chess. 81 123 190

Story Role / Major Arcs

Heavenly Eagle Stronghold Poisoning

Yin Daoyan answered Shen Hongyu's urgent summons to Heavenly Eagle Stronghold, where Shen Xuexin and thirteen others had fallen into unexplained unconsciousness. He swiftly identified the cause as a complex poison and later created an antidote, while refusing to entangle himself in the Shen family's internal power struggle. 69 70 71

Taking Zhong Lin as a Disciple

After seeing Zhong Lin grasp and master sword techniques with extraordinary speed, Yin Daoyan formally accepted him as his disciple. He subsequently brought Zhong Lin to Hundred Herbs Hall, where Zhong Lin became the Young Master of the hall and received access to its personnel and resources. 77 80 85

Blood Demon Sect Investigation

Yin Daoyan investigated the reappearance of the Blood Soul Pill and the Blood Demon Sect alongside Jing Tang. He presented Zhong Lin's portrait of “Military Advisor Han” as evidence, though Han's true identity remained unknown. 79 81

Later, Yin Daoyan, Gu Yourong, and Mei Weixuan killed rebel leader Guo Yanhai and other rebel leaders, but Han Jin escaped. 231

Sword Cauldron Sect Recognition

Yin Daoyan introduced Zhong Lin to Sect Leader Yu Jinglei and proudly presented his disciple's accomplishments as a Rank 3 Inner Breath martial artist and Rank 3 Pill Refiner at seventeen. 124

By the time he reunited with Zhong Lin, he had become an Innate martial artist, Fifth-Rank Pill Refiner, and Guest Elder of the Flying Sky Treasure Tower. 263
