The Legitimate and Illegitimate System: Sukuna's Brain Is for Sale from the Start

The moment she opened her eyes, Que Li had been reborn in the Heian era in the body of the eldest legitimate daughter of the Kamo family.

Miss Kamo was beautiful and graceful, with a lovely voice and manner. She had inherited her family's traditional technique and was also an exceptionally powerful jujutsu sorcerer.

Yet even a woman with such a perfect background and talent had a hidden pain.

Her younger brother was not actually her biological brother. He was an illegitimate child born to a woman outside the family, registered under Que Li's mother's name and passed off as the legitimate heir.

On the day her stitched-together little brother came to serve tea to the family...

A soft ding suddenly sounded in Que Li's ear.

"Greetings, dear Host. Your 'Legitimate Lineage and the Path to the Pinnacle of Battle-Crazed Offense' System No. 1111 is reporting for duty. Wait! How dare an illegitimate child born to a concubine presume to call the noble legitimate, legitimate, legitimate... legitimate, legitimate, legitimate daughter his sister? Know your place! Sell him off at once!"

All right, all right.

From then on, Que Li's life was like having cheats enabled.

System No. 1111 not only promised to take her to the Myriad Worlds and spread the glorious doctrine of legitimate lineage, but also to help Que Li become the most aggressive of all aggressors and the strongest of all strong people.

What is this? A cursed spirit with no ancestors dares attack the Host? Sell it off!

What is this? Ryomen Sukuna, a mere illegitimate son, dares attack a noble legitimate daughter? Sell him off!

What is this? Some pretty boy from the Ubuyashiki family, without even broad shoulders, dares compete with Lord Que Li for the title of mining champion?

He doesn't know what's good for him. Juan Guo, Su Guo, go! Smash his mouth!
