The Sexy Demon Lord Is Only Three and a Half

Xie Qingning is the foremost figure of the righteous path in the world of immortal cultivation, a revered senior sister who is as cold as ice and impossible to approach.

Yan Qing is the despised Demon Lord, alluring and unrestrained, with cultivation of the highest order. The righteous sects want nothing to do with him, yet they cannot defeat him.

But one day, upon learning that something had gone wrong with Yan Qing's cultivation, Xie Qingning seized the chance to strike while he was weak and set out under orders from her master to destroy the demon.

She never expected Yan Qing to outwit her. She lost consciousness, and when she awoke, she had transmigrated into the modern world as the six-year-old daughter of the Xie family. Yan Qing, meanwhile, had become a pitiful three-and-a-half-year-old orphan taken in by the Xies.

Xie Qingning had to hypnotize herself countless times: Don't hit the child. Don't hit the child. Hitting children is against the law here. She did her best to get along peacefully with Yan Qing.

But her patience wore away with every time Yan Qing climbed into her bed.

Xie Qingning snarled in exasperation, "Yan Qing, get out!"

Yan Qing's petal-like lips quivered, and tears came at once. "Auntie, Sister doesn't like me..."

The Xie parents said, "Xie Qingning, take good care of your little brother!"

Xie Qingning: ...How am I supposed to live like this!

Bonus scene:

Three-head-tall Yan Qing, as delicate and adorable as a little porcelain doll, tugged down his clothes to reveal a round little shoulder, then flirted at Xie Qingning. "Senior Sister, am I pretty?"

Xie Qingning (slowly clenching her fist): "Believe me, I'll knock your head off!"

Cold, short-tempered, straight-laced senior sister X alluring, flirtatious Demon Lord.

The senior sister stays clueless and doesn't fall in love before adulthood. Mwah~

Theme: Sometimes you can't judge by appearances.
