Lin Yan's growth path is full of thorns. When he was five years old, he got lost in the hill behind his ancestral grave, but was guided by an old elm tree; when he was seven years old, he stopped the medicine shop owner from discarding moldy licorice because he could hear the "cry" of the licorice, and the licorice actually cured the patient.

In order to save her, her father carried her on a journey to find Xuan Zhenzi in Qingxu Mountain.
