Monster Girl Development Master.

The centaur tyrant Lisander clashed head-on with the incinerating dragon Celine. Fenrir Piper summoned her loyal dog-girl guards to stop Serafina from descending from the sky, and the two pairs of sisters fought each other. Meanwhile, the fallen morning star Lilith subtly stirred her emotions, attempting to slip into her sister's arms and cast a "curse" on her brother-in-law, Johnson. But the turning pages of a book blocked her way. Missy, wearing a pointed priestess hat, raised her smooth chin, about to make her demands, when silver metal flowed first. The perfect head maid, Zero, intended to claim her reward and fuel, but the icy seawater transformed into a blue wall, repelling the metal's intrusion.

"A bunch of idiots~ small fry~"

The ghostly succubus ignored emotional interference, barriers, shields, and her physical body, preparing to enjoy the pleasure that penetrated to the soul. But a holy light descended first, and the angel queen Ines descended with divine majesty, powerfully interfering with the entire room. However, before she could set up the shackles of her royal authority, Beshi had already rushed in. Her fleshy body swayed, using the powerful force of the earth to resist the majesty of the angel. Then, many tentacles stretched out from the water wall, and octopus girls, Kraken girls, squid girls, and others rushed into the battlefield.

Amidst this chaotic situation, Alice, who had fully taken control of her new body, entered, combining the tender innocence of a newborn with the sacred majesty of a goddess. She possessed both naive purity and a voluptuous, alluring goddess-like figure. However, she was stopped by everyone as soon as she took a step closer to Zhuang Sen.

The gazes of the numerous monster girls inside and outside the house met, and they all saw the determination in each other's eyes.

war?

No! It's a fucking war!!

Amidst the sympathetic and envious gazes of humans, and the yearning and anticipation of the monster girls, a great battle was about to erupt. But the next second, the images spanning the three worlds vanished abruptly, and only those with exceptional eyesight managed to capture, in that instant, the astonishing reversal that erupted from the monster girls' layers of suppression.

Just the thought of having the chance to enjoy that kind of treatment made them hum softly.

……

Seven days later, the re-creation was finally declared complete. The three realms were also fully established and popularized.

Of course, this isn't isolation, so there are connecting paths between the worlds. However, these paths aren't purely physical but rather based on rules; only those that conform to the established rules can pass through. For example, going from the starting world to the battle world is the simplest—it just requires voluntary travel. But to go from the battle world to the starting world, the monster girl must receive an invitation or permission from the other world. In other words, if they are a normal married couple, they won't be separated by distance.

Of course, the monster girls' obsession is incomprehensible. Those "abandoned" monster girls will not give up because of this. In order to prevent these monster girls from becoming extreme, they can choose to communicate with their partners and then meet with their partners with the help of the corresponding civil servant monster girls. As long as they can successfully reconcile, they can go there.

To reach the "Sweet Home," one can either demonstrate absolute power in the world of struggle or make outstanding contributions in the world of origin, as long as one truly desires to become strong... I mean, to like Johnson.

As for whether or not one can do this or that, that depends on whether one can blast away those seniors and juniors who are blocking the way.

This is the world of monster girls, humans, and their gods.

Post-Day Talk: Mother's Kindness and Daughter's Filial Piety

An ordinary day descended upon Zhuang Sen's sweet home.

However, the arrival of dawn did not bring any change. Zhuang Sen's room was still filled with lewd sounds, and the sounds of flesh colliding and entwining rose and fell, making Xiao Lamia, who brought breakfast over, feel very tired.

"Honestly, it's been three days and three nights, and they still won't let Dad rest. A bunch of shameless old women."

Little Lamia spoke loudly, but the voices from the other side of the door not only didn't subside, but grew even louder, making Lamia's fair face flush red with anger. She was the daughter of Zhuang Sen and Dantalian, named Zhuang Dan. She had the same fair skin and pure white scales as her mother, but her figure was more slender and she was much shorter, just a little girl appropriate for her age. However, as a monster girl, and born with a high-ranking fifth-level bloodline, her strength was far greater than her appearance suggested.

"Don't waste your energy, Dan." A girl, slightly shorter than Lamia and with healthy wheat-colored skin, approached. However, unlike the still-developing Lamia, she already had two small mounds on her chest. Judging from her figure, she was a dwarf. She was the daughter of Johnson and Nia, named Joni.

"Xiao Ni, how many times have I told you, you have to call me 'older sister'!" Xiao Dan put her hands on her hips, glaring at her younger sister. She was her father's eldest daughter—not counting the shameless Alice. This old woman, who had lived for countless millennia, dared to compete with her for the eldest daughter's position!

“But we were born at the same time, Dan.” The dwarf woman said lazily, turning towards Zhuang Sen’s door and tiptoeing to reach the doorknob, but always falling just short.

"Don't waste your time. You're too short to reach her. Nia's mother is obviously just fooling you." Zhuang Dan ruthlessly attacked Zhuang Ni's weakness. The dwarf mother's size, like their ragtag sexual skills, was unchangeable, especially compared to the Lamia subspecies.

“But it’ll be soon, right?” Zhuang Ni struggled to stand on tiptoe, her fingertips touching the bottom of the silver handle, and smiled with satisfaction: “At least my mom just wants me to grow up a bit so I can be with my dad. It seems like Dantalian’s mom’s requirement for you is that you have to beat her, right?”

"Goo-"

Zhuang Dan let out a soft, resentful cry, her voice so sweet and endearing it could make anyone willingly choose the smallest bullet. But little Lamia harbored a fierce rage, quickly gritting her teeth: "Just an old woman's jealousy! Once I beat her, I'll make sure she can only see Daddy once a month, no, once a year!"

"Oh? Is that what you think?"

A gentle, mature voice rang out, causing the scales on Zhuang Dan's tail to bristle: "Mom—Zhuang Jie!!!"

"Hehe~" The pink-feathered Happy switched back to its original voice, laughing as it dodged several light bullets in mid-air. "Little Dan, you're so silly. How many times have you fallen for this trick?"

"Call me 'sister'!"

"No way! You only hatched two days earlier than me, why should I call you 'older sister'! Besides, I was fertilized before you!"

"You guys are so noisy... Hmm, can I eat something first, Xiao Dan... Sister?" A lazy voice came from the side. Zhuang Dan skillfully slapped her tail and pushed aside the vines reaching for the plate in front of her: "Xiao Na, how many times have I told you, don't stay up late! You're a Na Wen type! You need to get more sun!"

"But, ha~ the feeling from Mom's side is so comfortable~" The little girl, naked except for a few green leaves covering her three key points, yawned as she spoke. But the next second, she was startled awake by her sisters' wide-eyed stares.

The eldest sister, Zhuang Dan, pressed the question first: "What did you say? Hanna's mother shared feelings with you?"

Zhuang Jie followed up: "It's okay to lie to your sisters, but don't lie to yourself. Anawens don't have empathy, right?"

Zhuang Ni nodded in agreement: "Hana's mom doesn't even show us what she and Dad made, how could she possibly give you empathy training?"

"Exactly, Xiaona, are you hallucinating?"

Although that's what she said, Zhuang Na could tell from her sisters' expressions that if she didn't explain clearly, she might die today. Besides, she wasn't lying!

"The Flower Queen has the ability to unilaterally empathize with the Anawa race, and I'm already fully developed! Look, I've already grown flower buds~"

For the Anaven variety, the appearance of flower buds signifies maturity, and flowering indicates the start of adolescence.

"Ah, it seems real. Let me touch it..."

Snapped!

The snake-tailed creature opened its pale little hand and casually tucked the flower bud that Zhuang Na had flaunted back under her leaves. Only after this series of actions was finished did the other little girls react, glaring at the little vampire who had jumped out from the corner: "Zhuang Xue! How many times have I told you? Before you've mastered [Life Drain], you're not allowed to touch anyone else!"

As the daughter of Johnson and Mira, and a True Ancestor, she can absorb life force even from mere touch, especially during her developmental stage. Therefore, the little one usually wears special gloves. However, she inherited Mira's love of research and often takes off her gloves to touch things with her bare hands, causing some trouble in the process.

Zhuang Xue pouted and put on her gloves: "Nothing will happen, really~ Can't you guys contribute a little to science?"

Zhuang Dan was about to teach this bookworm a lesson when she suddenly sensed something was wrong. She looked around and frowned suspiciously: "Wait a minute, why are you all here?"

Generally, since they're not yet allowed to do anything fun with Zhuang Sen, the little ones won't come looking for trouble. She's the only one responsible for bringing them food every day, and Zhuang Ni will try to open the door. Why are there so many people today?

Zhuang Na, the most honest of them all, blushed and said, "Mom said before that when I bloom, I'll..."

Zhuang Na proudly flapped her wings: "I'm old enough now~ Look, my feathers are all grown in~"

Zhuang Xue rubbed the red marks on the back of her hand and said happily, "Me too. Although it hasn't been long, I can barely control my blood addiction."

???

Zhuang Dan stared at her sisters in disbelief. Before she could angrily rebuke these little liars, more figures appeared. Flying in the sky, the red dragon sisters Zhuang Lin and Zhuang Fei, though of different mothers, looked like twins. The young Behemoth, Zhuang Xi, small in age but the largest and most robust of the sisters. The green-haired centaur, Zhuang Li and Zhuang Po, carrying a golden-haired dog-girl and the tallest in terms of sheer height. There was also Arachne, Zhuang Ya, who always liked to hang upside down from the rooftops on a spiderweb; the fallen angel Zhuang Sheng, with jet-black wings, snow-white skin, a childlike face, and enormous breasts; the headless knight Zhuang Lai, whose skin was bluish and who never seemed to put his head back on; and the book demon Zhuang Mi, who was already wearing glasses and wouldn't let go of a book…

Apart from the robot Zhuang Yi, who is still too young, the mermaid Zhuang Li, the succubus Zhuang Nu, and the angel Zhuang Yi, everyone else came!

Zhuang Dan felt a deep sense of betrayal: "You, all of you!"

"Sorry, Sister Xiaodan," Zhuang Na apologized softly, her tendrils reaching for the doorknob like hands and feet. Some of the others were expressionless, some looked up at the sky, and some deliberately provoked, but in Zhuang Dan's eyes, they all meant the same thing—showing off! Pure showing off!

It's all my awful mom's fault!!!

But thankfully, there's still Xiao Ni, at least she's there too...

Click.

The door was opened by Zhuang Ni, who jumped up.

Before Zhuang Dan could even feel the pain of being struck twice, she smelled a strong scent. Although it had been tainted by the scent of many old women, it was still her father's... The group of fully developed little demon girls blushed, but they all rushed into the room one after another.

Then a golden light flashed, and a golden, holy light barrier blocked their path, the smell, and the spectacular scene.

Zhuang Dan clenched her fists, instantly transforming into a dutiful daughter: Well done, Mom!

Zhuang Ni, the most anxious of all, jumped high: "Mom Dantalian! It's us! Not Zhuang Dan!!"

"Yes, yes, Mama Dantalian~ It's me, Jona~ Mama~ I've blossomed, just like you promised~"

The little one cried out sweetly, but the iron wall of holy light showed no sign of weakening. Instead, several voices came from behind the iron wall: "Little Na, you're still too young. Wait until the results are in before... um... tell the child... ha~"

"Little girl, you jumped up to open the door just now, didn't you? That's cheating, you can't do that. Besides, Mom has a feeling I'll definitely break the seven-minute limit today, so don't bother me... *sniff*"

"Xiaoli, go back and study hard. Mom needs to discuss the design of your new clothes with your brother."

"Xiaolin...Xiaoxi..."

Outside the door, the little ones stood frozen in shock, while Zhuang Dan stood with her hands on her hips, laughing loudly: "Hahaha, serves you right for betraying me!!"

As if their last breath had been taken away, the little ones roared, "What are you talking about, you old women! Hand over my darling!"

"Eating alone will get you judged by the whole clan! Mother! I'm here to save you!"

"Mom! I can no longer tolerate a monster girl like you who doesn't keep her promises existing in this world!"

"kill!"

"Weakness analysis complete, marked!"

"Dragon's Breath!"

"Destroy the Death Ray!"

With the combined efforts of the large group of superior beings, the iron wall formed by holy light was breached. The little ones, heads held high, stepped over the now-nonexistent doorway, and then...

"Mom's Iron Fist!"

The mothers, whose anger had been fully aroused by their unfilial daughters, unleashed a powerful attack, sending the walls of the Holy King's Palace flying into the sky once again.

——This time, I will kill my daughter without any regrets!
