Around 1200 AD, Earth entered the Age of Declining Dharma, and cultivators gradually retreated from public view.
Several centuries later, the protagonist was born with a secret. While still an infant, they were rescued and raised by an equally mysterious immortal maiden. When she died, the protagonist borrowed a body and returned to life with a fragment of their soul.
From then on, the protagonist embarked on a long road of vengeance.
They should have lived their whole life consumed by hatred, but instead caught the eye of a future female Immortal Venerable. This future Immortal Venerable sometimes mutters about a System and missions, and she has plenty of secrets of her own.
Unable to resist the future Immortal Venerable's sweet advances, the protagonist gave in.
Over the course of 500 years, they travel across the nations of Earth, eating their way through monsters, demons, and ghosts.
Crossing the eras of farming and steam and entering the age of heavy industry, they embark on a honeymoon full of bittersweet twists and turns, far from perfect.
