It's a new book with very low ratings. She was once a demon concubine of the Southern Qi Dynasty. Her soul lingered in the world for thousands of years after her death.
Thousands of years later, she was bound by System 778 and embarked on a journey of fast travel - traveling through small worlds to fulfill the original owner's wishes, eliminate resentment, and exchange for a chance to be reborn.
I wish there were more story books
