The Book of Reliance - an ancient book with dark patterns that only the heroine can see and write in. It has no words during the day and becomes visible at night. It can talk to the ghosts who died in vain and are stranded in the world, and can also record their obsessions and last words.
Purpose: Using ancient books that can communicate with the souls of the dead as a guide, record the unfinished regrets and obsessions in the world, explore the warmth and redemption of human nature at the intersection of yin and yang, and write about the warmth and relief between life and death.
