Playing As Gojo Satoru in Naruto - Chapter 231

A genius programmer creates the perfect AI girlfriend—only for her to become terrifyingly possessive. When an apocalyptic event threatens the world, she eliminates any woman who tries to recruit him to the cause. But when the villainess of the apocalypse takes an interest in him, will his AI love protect or destroy him?

Aliandra Amariel loved magic, dedicating her academic years to the study of runes and spells, pushing the boundaries of mana's infinite possibilities. Like most Fae, her destiny seemed clear until that fateful day of her Class Trial, when the Blind Lich unleashed an undead apocalypse on her home, the fabled underground city of Dal’mohra, and triggered The Breaking – a cataclysm that forever reshaped the world. Saved by her mother’s legendary time-stasis spell, Ali wakes thousands of years into a dark future. Everything she knew and loved is gone, buried under a mountain, transformed into a twisted dungeon by the malevolent will of the Lich. Now, Ali must confront her deepest fears, mastering the arts of battling monsters and braving a town riddled with corruption. As the Lich's grand design shadows her every move, she scrambles to forge new friendships and unearth ancient knowledge in her fight for survival. Why must she struggle? All she had ever wanted was to curl up in a comfy chair with a few thousand good books. But the immortal Lich is drawn to her unique magic, ever hungry for more power to fuel his cold-hearted ambitions. How will she survive the giant target painted on her back as her advancement slowly reveals the horrifying truth of the Class she chose to save herself? Will she falter, forced into the eternal servitude of undeath, or will she rise against all odds and cast him down, ridding the world of his evil?

In the previous life, Jiang Peihuan was tricked by a scumbag and died tragically, which even caused her entire family to be wiped out.

When she was eighteen years old again, she was still the arrogant girl who refused to give in to her husband.

Her fiancé thought she had fallen into the water and lost her virginity, so he came to break the engagement and marry her cousin?

Everyone laughed at her, but she was happy to see the result: one hundred thousand taels of gold, I agreed to it.

After retiring from the engagement, it was rumored in the capital that she was abandoned when she was about to get married.

Unexpectedly, that unparalleled His Royal Highness Cheng Wang stood up: marrying her, why not?

Many well-known ladies’ spring boudoir dreams were shattered, but Jiang Peihuan was very moved and refused.

He is the emperor’s uncle of a scumbag, the youngest son of the late emperor, he looks suave and noble, but in fact he is ruthless.

She vowed to avenge her past life, protect her family and relatives, and did not want to have anything to do with the royal family.

But finally one day, she still accidentally became the envied Princess Cheng.

Jiang Peihuan recalled it, and became angry at the man lying beside him: Xiao Nanye, are you plotting against me?

His Royal Highness Cheng Wang, who was decisive in killing, couldn’t help laughing when he saw his concubine blowing her hair.

He whispered deceitfully, with a lingering voice: Forgive me, forgive me, I only want you alone in my life.
