The Little Demon Lord I Raised Is Turning Evil Again Today

After transmigrating into a cultivation novel as the righteous sect's senior disciple, Cheng Yining is kidnapped by the future Demon Lord.

In the book, the Demon Lord Cang Tong is cold-blooded and murderous, destroying most of the cultivation world single-handedly. Cheng Yining is naturally on her guard.

When the candle goes out at night, the future Demon Lord, still with a bit of a baby face, appears before her. Cheng Yining starts to gather her energy, ready to defend herself, but Cang Tong lies down fully clothed, rubs her cheek against Cheng Yining's sleeve like a little animal, and curls up into a tiny ball to sleep.

Cheng Yining: Hm...?

Only then does she realize that Cang Tong knows nothing of warmth or cold, and cannot tell good from evil. The great villain who can destroy half the cultivation world with a flick of her fingers is clearly still just a clumsy little beast, ignorant and helpless.

With a pair of clear, bewildered blue eyes, she gazes up at Cheng Yining so trustingly, just like the cats she saw as a child.

Remembering the few lines in the book about Cang Tong's background, how she grew up among beasts and knew nothing of human society, Cheng Yining's heart softens completely.

Fortunately, Cang Tong is well-behaved and listens to her, so Cheng Yining resolves to diligently raise her little sister and guide the future Demon Lord onto the righteous path.

But when Cheng Yining opens her eyes again, she has arrived a hundred years in the future, in a strange place.

The little sister who had been sleeping obediently in her arms now stands before her with a sword, covered in blood. Her one remaining beautiful, glasslike blue eye is full of obsession, while the other, blind and dim, is greedy.

Amid the stench of blood, the one-eyed Demon Lord Cang Tong steps over the wreckage. Her cold, soft fingers part Cheng Yining's clothes and draw a long, lingering line of blood across her skin.

"Ningning," she murmurs, "never leave me again. You must never..."

Cheng Yining: ...??

After finally calming the Demon Lord of the future for now with a promise, Cheng Yining is just about to go meet her when a wave of dizziness hits. The obedient, bewildered blue eyes of her little sister are back before her.

A hundred years in the past, Cang Tong is like a little animal, confused and unsure what happened. "...Ningning?"

Cheng Yining: ...???

Cheng Yining: ??!!

To stop her sweet, clumsy little sister from becoming a brutal Demon Lord who tramples the male protagonist's bones, claims the female protagonist's opportunities, and rules without anyone daring to defy her, Cheng Yining leaps between two points in time, determined to save her sister and the entire cultivation world.

She thinks she has succeeded, but Cang Tong, whom she believed sweet and obedient a hundred years ago, pulls her into an obsessive kiss.

"Ningning, Ningning..."

The blue-eyed little beast calls her softly, innocent yet obsessive, biting her lip possessively and making her swear in the taste of blood.

"Don't leave me... Ningning, you mustn't leave me."

"You're mine..."

Only then does the upright senior sister realize:

...Could there really be something wrong with the way she raised her?

*

They say the senior sister offered herself to the demon, moving into the Demon Lord's bedchamber alone and making great sacrifices for peace in the cultivation world.

But no one knows that each night, when moonlight falls into the great hall, the Demon Lord, burdened by countless killings, leans against the senior sister's outspread moon-white sleeve and melts like spring water, weeping all over it.

Naturally, only the upright and kind senior sister knows what she is like.
