[Rebirth revenge power fantasy with an exceptionally strong heroine + female-led + unconventional cultivation + heroine with tons of golden fingers + System]

She'd just been used as cannon fodder in the war between humans and demons, literally.

Then she was reborn as a coder on Blue Star, and managed to work herself to death in front of her computer.

She closed her eyes, then opened them again,

and found herself dragged back to her original world, where she'd been dropped ten thousand years into the future.

Everything had changed.

The powerful demons had been completely wiped out, and her comrades-in-arms had long since vanished into the river of time.

Humanity had split into immortals and mortals, while the evil demons were kept firmly under the immortals' control.

Everything was in order.

In this life, she had been born into the noble Imperial Preceptor's household and become the dynasty's beloved Holy Maiden, adored by all.

Just as she thought she could lie flat and enjoy her life,

she was shocked to discover that she was the heroine of a tragic romance novel.

Countless men were vying to become her male lead so they could seize her fortune and destiny.

But this old soul, who'd lived through three lifetimes, had no interest in falling in love all over again!

Afterward, her life was plagued by misfortune. She was bullied wherever she went, struggling to escape and fighting for a chance to survive.

Yet she still fell into the hands of Immortal Lord Xiao Qian, who killed her in the Ten Thousand Demon Cavern!

Reborn once more, before the men could come after her fortune, she activated the demon bloodline hidden inside her.

She would seize opportunities, claim divine powers, cultivate as both an immortal and a demon, and begin her revenge!

In this life, she would make everyone open their damn eyes and see the power of their old ancestor!

(I can't come up with titles or write blurbs, but this really is a story about an exceptionally strong heroine. If you like strong female leads, come on in!)
