Transmigrated As the Villainous Adopted Son: Spoiling My Destiny Sister Until She Cries!

[A new genre of doting on younger sisters][Multiple female leads][Lots of fun]

My name is Gu Heng. When I woke up, I transmigrated into a fantasy novel about a dynasty vying for supremacy, and became the vicious adopted son of the Duke's mansion.

What's worse, the Duke's mansion also has a true heiress who is blessed by heaven.

In the original novel, the younger sister was bullied and ignored by everyone in the mansion, eventually turning evil and becoming a demon, which brought about a great disaster and led to the destruction of the entire Duke's mansion.

In order to preserve his adopted son's life of luxury, Gu Heng made a decision that went against his ancestors' wishes!

Spoil your sister and get a reward?

Sorry, my dark side is still my side!

Soft sister, isn't a sweet sister a sister?

The system was completely astonished by Gu Heng's unconventional and bizarre way of spoiling his sister.

So, besides being a simp, there's another way to be so provocative.

Years later, Gu Heng looked at the soft, adorable little girl in his arms.

"(♡⌂♡) My silly little sister, be good... let your brother see!"

"(*'he'*) I don't want to!"

......

My name is Gu Shiyun. I thought that destroying the Gu family would rid me of my inner demons, but I never expected to perish in the Supreme Tribulation.

Unexpectedly, when he opened his eyes again, he found himself back on the day he was falsely accused and forced to kneel in the ancestral hall.

As expected, that wicked older brother will seize the opportunity to steal her place in the Immortal Abode Academy and punish her by making her work as a maid in the master's house for a month as an apology.

However, to her surprise... the plot did not follow the trajectory of her previous life.

"That scumbag actually... is clearing my name...?"
