Fang Ling is the senior disciple of the Heavenly Law Sect. On the night after she broke through to the Golden Core realm and accepted disciples on her master's behalf, she had a dream. In it, she and her master were villains in a book, while the hero and heroine were the junior brother and junior sister she had just welcomed into the sect for her master.
In the dream, she discovered that her natural sword bones were damaged and coveted the bones of her new junior sister, who also had natural sword bones. To help her, her master even personally captured the new junior brother to force the new junior sister to give in.
But before the sword bones could be extracted, she died. Her master went mad at the sight of her corpse and fell into the demonic path. He later became a Demon Lord feared by all, constantly causing trouble for the hero and heroine.
Fang Ling woke with a start. She sat at the head of her bed and thought about it for half the night, but could not figure out how her sword bones could possibly be damaged in this cultivation world full of centenarians who had only just reached Foundation Establishment. She was only twenty-five and already at the Golden Core realm.
Recently, You Chenglang noticed that something was off about his eldest disciple. Every day, she did nothing but practice swordsmanship and secretly watch him. She also kept asking strange questions, like whether he loved her and whether he would enter the demonic path for her.
This left You Chenglang terribly flustered, both worried and hopeful.
Damn, did she find the painting I secretly made of her? Should I confess first?
The dream may have been fake, but my love for you is real.
The couple is the senior sister and her master: a seemingly aloof but actually gentle senior sister x a master who flirts with his words but is actually pure-hearted.
The title means that this is not the first time the master has fallen into the demonic path because of his senior sister. The heroine dreamed of just one of those times.
Theme: Face difficulties head-on and do not be afraid.
