In this world where demons, angels, and fallen angels exist, he, having just been promoted to a high-ranking demon, asks his beautiful junior in the Service Club's activity room, "Do you believe in the existence of demons?" This is the story of a half-demon, half-human, who gradually lets loose in this seemingly peaceful yet extraordinary world as he tries to subdue his familiars.

[Apocalypse + Many Children, Many Blessings + Superpowers + Abundant Beautiful Women + Decisive and Ruthless]

A zombie virus outbreak has brought about the apocalypse. Qin Feng obtains the "Many Children, Many Blessings" system, which grants him superpowers by collecting beautiful women and even more super rewards for having children.

Qin Feng, I like you. I only teased you before to get your attention.

A girl wearing a JK uniform, white stockings, and with snow-white skin spoke shyly to Qin Feng.

"Really? Ruoxue, I actually like you too."

Qin Feng felt a surge of excitement. The girl confessing her feelings to him was Bai Ruoxue, the class monitor and the school's most beautiful girl, a woman that countless boys dreamed of having. He never expected that she would confess to him.

"Of course it's fake. You might not have a mirror, but you still need to pee, right? Why don't you take a piss and look at yourself in the mirror?"

Bai Ruoxue suddenly changed her demeanor, her disdain undisguised. (To find out what happens next, please read Chapter One.)

[Ocean survival + multiple female characters + not a saint + later-stage maritime family]

The story begins with me surviving on the ocean, and I'm the only guy in my class!

Thankfully, the "Many Children, Many Blessings" system has been activated!

[Ding! The host has conceived their first child, at which point any item can be converted into an infinite amount!]

When the entire ship was in despair due to lack of water, Jiang Ye silently looked at the school beauty.

School beauty (blushing): "You beast! But for everyone's sake..."

[Congratulations, host! Conversion successful! You have received "Pure Mineral Water + 9,999,999!"]

When the eerie sea monster attacks, the raft is about to break! Jiang Ye then looked at the mature dragon girl who had awakened her S-rank talent.

Dragon Girl (tsundere): "Hmph, you want me to lay dragon eggs for you? Not impossible..."

[Congratulations, host! Conversion successful! You have obtained "Alloy Super Armor +9,999,999"!]

Beautiful teacher Lin Zhixia sighed and said, "Jiang Ye, I think we need to 'plan' the family's future?" (meaningfully)

All the girls on the ship: Class monitor, in order to survive, please be responsible for us!

[Zombies] + [Beauties] + [Supplies] + [Infinite Duplication] + [Decisive Killing]

A global catastrophe, the apocalypse descends.

A piece of beef → replicate → ∞ beef

A bullet → replicate → ∞ bullets

A Gatling gun → replicate → ∞ Gatling guns

...

From priceless treasures to everyday necessities like firewood, rice, oil, and salt—just a single touch from Lin Qin, and he can possess an unlimited amount.

"I've got tons of supplies—it's only reasonable to support a few goddesses, right?"

After traveling through the world of Demon High School and wandering around in it for a thousand years, when Chen Eliog became the fifth demon king of the underworld, he received an invitation from a dimensional chat girl.

Out of boredom, Chen Eliog chose [Accept].

Cang Yue: Welcome newcomer! I am the strongest fighter among all the girls, let me know!
