Li Yanluo was the cherished darling of the immortal sect, blessed with outstanding talent and a smooth path to immortality.
That was until her master took an ordinary mortal woman named Wen Shuyi as a disciple.
For some reason, from then on, Li Yanluo suddenly lost everyone's favor.
She gradually became deranged and twisted, committing many cruel acts against Wen Shuyi.
On the day her crimes were exposed and she was punished, Li Yanluo discovered that she was living inside a transmigrate-into-a-book story.
Wen Shuyi was the heroine, and would soon follow the tasks laid out by the System to win over everyone and capture their hearts, as well as redeem the demon Rong Qi.
Meanwhile, because she opposed the heroine, Li Yanluo would eventually have her immortal bones stripped away and be married to Rong Qi as Wen Shuyi's replacement.
That wasn't all. After learning that Rong Qi kept her only because he was deeply in love with Wen Shuyi and feared she would continue harming Wen Shuyi if left at large, Li Yanluo became even more deranged. She committed evil deeds while secretly plotting to kill Rong Qi, but in the end, he cut her down with his sword.
In short, she was a vicious supporting female character.
With no other choice, Li Yanluo immediately began trying to save herself.
She couldn't control other people or the plot, but she could be herself.
When Li Yanluo's childhood friend and betrothed, Shen Qianshan, announced in front of all the immortal sect residences, "I want to break off my engagement with Yanluo. The only one I will ever take as my Dao companion is Shuyi!"
Everyone said, "Yanluo, are you jealous?"
Li Yanluo replied, "I'll step aside and give you my blessing. Rong Qi is looking for a new bride among the immortal sects. I'll go in her place!"
What they didn't know was that Li Yanluo had already finished reading every book in the sect's collection, and was only waiting to marry Rong Qi so she could infiltrate the demon realm and keep studying.
She would no longer be the vicious supporting character from the original story, who became violent and gloomy after being sent as a replacement bride and gave up on herself.
She would become a grandmaster of both the immortal and demonic realms, more powerful than anyone.
Rong Qi was born a demon, powerful enough to reach the heavens and earth, unafraid even of the Heavenly Dao.
The only one he was helpless against was his wife, Li Yanluo.
The immortal sect hadn't sent Wen Shuyi, but Li Yanluo instead, which greatly annoyed him.
He was plotting how to torment her, but whenever he got close to her, he was struck with splitting headaches.
It was as if she were his nemesis.
But Rong Qi refused to back down.
The harder it was, the more determined he was to overcome it.
Who knew that in overcoming it, he would end up unable to bear being apart from her?
