Lin Wan is the scent master of the "Ningxiang Pavilion" and practices with "nose breath" - he can distinguish hundreds of incense, smell emotions, break illusion formations, and even talk to the dead through "fragrance souls". She was hunted down by the "Incense Soul Sect" for mixing up the "Incense of Rebirth", which can help the souls of the deceased to rest, but it triggered the sect's magic of "nourishing souls and refining incense". The leader of the Fragrant Soul Sect was actually her missing master. He was corrupted by the "Fragrant Poison" when he tried to save her, thinking that "nurturing the soul" would make his apprentice immortal. Lin Wan discovered the "Fragrance Soul Pearl" in the sect's forbidden area, which contained the memory of the ancient "Xiang Ancestor": Xiang Ancestor was originally a human race. He created the "scent-smelling technique" because he couldn't bear to see living beings being "manipulated by smells" (such as soul-enchanting incense and bone-eroding incense), but was slandered as a "witchcraft" by the immortal sect. In the end, Lin Wan used the "Seven Emotions Fragrance" (joy, anger, sadness, fear, love, evil, desire) to reconcile the violent energy of the Xiang Soul Pearl. After the master woke up, he destroyed his sect. Lin Wan took the "Xiang Ancestor's Notes" and founded the "Jingxiang Hall" to teach the world to "nurturing one's nature with fragrance and not to be enslaved by fragrance."
