Ling Luo'an was an utterly ordinary cannon-fodder specialist at the Transmigration Into a Book Bureau, until a System bug sent her into the wrong book.
Luckily, life was going pretty well.
Despite having a mixed spiritual root, she had miraculously risen straight from an outer sect servant disciple to the inner sect.
And the Immortal Venerable in the hall was generous, gentle, and possessed an air of transcendence.
But Ling Luo'an didn't know that whenever the Immortal Venerable, Fang Buyu, approached, the System was so terrified it felt like its soul was flying all over the sky.
Hosts who have taken memory-erasing pills really are something else.
Even in front of the villainous demon lord she'd tricked out of his demon core, deceived into marriage, and faked her death to escape, she could smile so carefree and oblivious.
And she chatted so merrily with the original body's childhood friend. Behind her, the Host was seething with resentment, while the demon lord's eyes were so bloodshot they looked ready to bleed.
But her Host was still grinning away like a fool.

The thing Fang Buyu regretted most in his life was listening to his wife six hundred years ago and going to the village's eastern end in a thunderstorm to buy her water caltrops to eat.
When he returned, all that remained was blood covering the ground. His wife was dead, and not even her body was left behind.
To bring his mortal wife back to life, Fang Buyu tried every method he could find: the Spirit-Gathering Pagoda that could restore vitality, forbidden arts that sacrificed souls. He even broke through the barrier and fought his way into the Netherworld's Reincarnation Shore.
But there was nothing. Not even a trace of his wife's soul.
It was absurd, as if she had never existed at all.
Fang Buyu finally broke down. If his wife was gone, then the world had no reason to exist either.
Then, suddenly, he caught sight of an outer sect servant disciple and froze completely.
It was his wife!
But could someone tell him why his wife didn't recognize him?
Why didn't she keep her eyes on him?
Why was she smiling at someone else?
Premise: Those who never forget will eventually be answered.
