In My Hero Academia with a Jujutsu Kaisen Gacha System - Chapter 22: NO. - New Roommate

On the night of her coming-of-age ceremony, Nan Zhi is lured into a trap by the people closest to her and falls pregnant.

Four years later, she returns with her son.

A respected and domineering man suddenly barges into her world.

“Speak! Who is the child’s father?”

An adorable child holding a water gun appears out of nowhere, shouting, “Who is this wild man? How dare he snatch Brother Jie’s goddess?!”

From then on, two small domineering brats and a manchild are added to her world.

In the middle of the night, he sneaks into her room, pressing a heated kiss onto her lips.

“Woman, do you know what’s the result of stealing my seed?”

“What?”

“From now on, you have to let me kiss and pamper you everyday.”

Erm… How was her inability to walk the next day, the result of his pampering?

He is a young man without a spirit root. It is believed that this denies him the chance at cultivation. However, a mysterious lady imparts a Supreme Demon Classic to him and from then on, he starts his path of cultivation.
He undergoes a total transformation to emerge as the most fearsome and powerful fiendish demon in his era, that even immortals and fiends are fearful of him, and saints are at his beck and call.
Mastering the Supreme Demon Classic is the turning point in his life. He is able to unleash his immense and divine power from within, illuminating the entire universe!
