The Book of Fuxi was modeled after Fuxi with the aid of Nuwa to help accompany Fu Hua after the two's passing.
Appearance[]
Her appearance was based on Fuxi, having long brown hair and blue eyes. As an ELF, she is much smaller than the human Fuxi.
Personality[]
Due to her draining batteries, Little Book is often sleepy and tired, finding ways to best help her conserve energy in order to not leave Fu Hua so soon. She is dedicated solely to the making sure Hua doesn't suffer from loneliness, and despite being an android, developed human attributes, like being compassionate and obsessing over bao (stuffed bun).
Story[]
Springfest[]
Created by Nuwa and Fuxi as a gift for Fu Hua, Little Book was to be her family and keep her company after the twins would eventually die. However, as the technology was not advanced enough back then, Little Book's batteries were draining and would eventually die, making her sleepy and dozing off very frequently. As a precious gift and all that was left from the twins, Hua took care of her and tried not to have her work too much. Before her batteries shut down, she managed to convince Hua to enjoy a Spring festival with her. Hua promised her that when the technology is advanced enough, she will wake her up, and they will be together once more.
Chapter XXXVII[]
The Herrscher of Sentience at one point speculates that Fu Hua is spending her time leisurely drinking tea with the Book of Fuxi, suggesting that Fu Hua does indeed make good on her promise to restore her.
Testing Blade[]
Book of Fuxi proposes to use Herrscher of Sentience's mind space to look for Fu Hua after she couldn't be found when Book woke up due to the special connection between them. However, the Herrscher is unable to locate Fu Hua which worries Book greatly as this likely means something awful has happened. Herrscher of Sentience attempts to ease her worries by reminding her of Fu Hua's strengths and experience. Before long, the two are confronted by a mist of unknown origin that can manipulate monsters conjured by Herrscher of Sentience. Shielded from the mist by the Herrscher, she gets to hear its request—to not venture into bubble universes to look for their missing companion and instead remain in place.
