Good-for-Nothing Cultivator: I Slacked Off, and Now My Senior Sister Rules the World

She is the good-for-nothing senior sister of the Scarlet Sky Sect, the top cultivation sect in the Boundless Immortal Domain. Out of resentment, she tries to seduce her junior nephew, who cultivates the Merciless Dao.

Her junior nephew is honest and steadfast, and stays true to his Daoist heart. Together, they travel far and wide, slaying demons and monsters and protecting the righteous path...

In the end, he falls helplessly in love with her...

Wait, why is there demonic energy on her nephew? Has he gone mad in his cultivation?

She can use demonic energy too? Could she be a demon cultivator by nature?

What? The Scarlet Sky Sect's leader, her own younger sister, is actually a member of the demon race?

The Scarlet Sky Sect is about to turn upside down!

One was born with immortal bones, but sealed and reduced to a good-for-nothing...

One was a renowned prodigy, but the daughter of the Demon King...

And one was a future chosen of heaven, but the Demon Venerable...

Even the revered Scarlet Sky Sage was nothing more than a despicable villain who coveted another sect's supreme treasure!

The seal shatters. She returns from the dead, making a powerful comeback with her inborn immortal bones. The demonic heart of the person she loves most awakens, and he becomes the new Demon Venerable...
