Xiao Su, the president of the Xiao family, has been secretly in love with his business rival Shen Ling for many years. A car accident caused him to enter the fairy tale and become the father of the male protagonist - Mo Yuan, the head of Qingyun. He also had an old face. What made him even more devastated was that the male protagonist's Taoist companion and poison doctor Su Wan actually had a face exactly like Shen Ling's.
The object of his crush became his "future daughter-in-law", and Xiao Su felt sour in his heart as he watched the face that he thought about day and night show its edge towards his "son". In order to get rid of this ridiculous identity and old age, he embarked on a road of crazy search for medicine. However, when dealing with Su Wan, he found that the other party always said some "inappropriate" words and looked at him with unspeakable complexity.
When Xiao Su finally regained his appearance, he bumped into Su Wan muttering to a manuscript late one night - "Xuantian Immortal Path" was clearly written on the manuscript. It turns out that the book on immortality that confused him was actually written by his crush; and the "future daughter-in-law" who made him both love and jealous was Shen Ling himself.
When the farce of misplaced identities finally comes to an end, two souls who have traveled through books meet on a narrow road in the world of immortality. How will this secret love that started in reality but messed up in the book end?
Intent: to run in both directions across time, space and identity, to bravely pursue true love
