Demonic Witches Harem: Having Descendants Make Me Overpowered!

One year had passed and the world has change a lot.

The land once scorched by disease and corruption now trembled beneath the drums of war.

The Hyparia Kingdom stood in Claude's path—even when Claude did negotiation with them, they won't give up, even when they would lose ultimately and pathetically like this.

Many of their small town and villages were on his hand and they keep marching near to the capital, but for now, they were attacked by Duke Ciel soldiers who were about 50.000 men.

"How the hell they get many people after that damned plague?" it was what Claude asked the first time intel come to him.

He forgot that there were some kingdoms who were specifically working in this line of work. Selling their people service as a soldier ready to war for some gold coins from different continent.

And yet, amidst the distant echo of marching boots and the occasional rumble of siege towers, Claude walked casually along a ridge with his children, as if it were a stroll through the palace garden.

His black cloak rustled in the wind, and behind him trailed four figures—his pride, his legacy, and perhaps the most dangerous minds ever born to this world.

They looked like children, barely seven years old, though none of them had even reached the age of three.

Their growth was unnatural—shaped by bloodlines, sorcery, and Claude's ruthless guidance. But their eyes no longer shimmered with innocence.

"Alright," Claude said, gesturing to the valley below where Hyparia's forces were arranging their formation.

"You see those siege towers? Let's say you're the enemy. What would you do?"

Vega adjusted his gloves, expression cold and calculating. "They've put all their focus on brute force. Weak supply lines. Too confident in their walls. I'd let them stretch thin, then burn their support wagons."

"Good. Now, Lyra?" Claude turned to her.

She tilted her head with a smile, clasping her hands behind her back like a prim little lady. "If I wanted them to scream, I'd steal their captain's stamina with my Plunder and let him collapse in the middle of battle."

"Cruel," Vega muttered, crossing his arms. "And fake. You're the most manipulative one here, yet you act like the cutest."

"And you're just mad I figured out how to steal magic," Lyra grinned, sticking out her tongue.

Claude just shake his head, "You guys really close, huh?"

"NO!" both of them exclaimed in unison and crossed their arms and frowned.

Carina, walking beside Claude in silent steps, raised a finger. "Can I test my confusion spell on their archer squads later, Father? It's stronger now. I can make them aim at their own men."

Claude nodded. "When the signal comes, yes. Controlled chaos only."

Antares, bounding ahead with excitement. "I've named the new beast! He's too big to come here, but he really wants to eat a ballista."

"You talk more than you fight," Vega murmured.

"And you think too much!" Antares beamed. "Anyway, he's a six-legged lizard! Big one! Breathes acid!"

Claude let their chatter go on, smiling faintly.

These weren't ordinary children. They weren't meant to be. He promised he didn't want them to dragged into politic bullshit at younger age.

But hey, this is war and they need to learn how to be a lord and a king.

Claude knelt near the edge of the ridge, brushing the dust from a smooth rock and placing his hand upon it.

"The world isn't won by strength alone," he said, his voice calm but firm. "It's won by understanding where to strike, when to wait… and who to sacrifice."

His children circled around him, each listening intently.

"In Hyparia's case," he continued, pointing to the distant banners, "they still believe this war is about righteousness and honor."

"They pray to gods that never answer and trust in a king who hides behind faith. But you already know the truth—there is no god, no prophecy, no divine fate. Only us."

Lyra blinked slowly. "Then what do we do, Father?"

Claude's smile returned, thin and unreadable. "We make them lose faith."

"Burn the banners first?" Vega asked, his tone dry.

"No," Claude replied. "Burn their food. Then their priests."

Antares whistled softly. "That's mean. I like it!"

Beside him, Carina remained quiet, her gaze steady on the enemy camp below. "If they starve and lose their magic protection, they'll turn on each other before we even attack."

Claude glanced at her with approval. "Exactly."

They were still so small. Carina's hands barely wrapped around the hilt of her ceremonial dagger, and Antares couldn't hold his staff steady without summoning a creature to do it for him. But Claude didn't need them to fight with swords.

He needed them to think like monsters.

"You will inherit a world that fears you," Claude said, standing again.

"Not because of your strength, but because of how you make them feel helpless. That is the power you must understand—dominion over hearts and minds."

Antares tilted his head. "So... does that mean we don't get to fight?"

Claude chuckled faintly. "Not today. This lesson isn't about blood. It's about control."

He stood up slowly and stretched his hand toward the distant enemy formation—Hyparia's army, all fifty thousand men and war beasts gathered proudly under Duke Ciel's banner while his own army was still behind the ridge, waiting for his command.

But it seemed today wasnt their day, since Claude want to show off to his children and also he was itching to use Antares Beast Taming skill since forever.

"And speaking of control... let's begin."

Antares instinctively clutched the staff in his hand, ready to chant some spell. So did all of his children with their own weapon and unique skill, but Claude held out his hand.

"No need," he said, voice calm. "This is your ability, yes... but for now, it's mine to command."

Dark magic circle lit up over Claude's arm in a perfect recreation of Antares' own incantation circle—except larger, more complex, warped by Claude's overwhelming presence.

[Unique Blood Skill Activated: Abyssal Summoning has been chaneled!]

[You can use it now Claude!]

The ground beneath the enemy troops began to tremble.

"W-What's he doing?" Antares whispered, wide-eyed.

"You'll see," Claude murmured.

In the center of the enemy camp, a brilliant crimson sigil bloomed like a flower—one none of them could see. It pulsed once and again like heart beat as they were panicked.

Dozens more sigils joined it, appearing beneath the feet of soldiers, catapults, siege towers.

The mage tried to cancel the spell and chant the protective barrier but for no use. Claude magic, with his three stars evolution and his enormous amount of mana was unstoppable.

And then came the sound—an unnatural thrum, like a heartbeat too loud for the earth to bear.

Claude's voice dropped, low and final.

"Sacrifice: accepted."

In a blink, fifteen thousand men collapsed—instantly. No cries or screams. Just silence as their life force was drained in perfect synchronicity, spiraling into the sky like blood mist.

From that mist, a rift tore open above the battlefield. A hulking creature forced its way through—scaled, six-legged, twice the size it had ever been under Antares' control.

Acidic vapor spilled from its maw, melting everything it touched. Siege towers crumbled. Screams finally began as the soldiers finally know what hell truly was.

Antares stood frozen, eyes wide. "T-That's! How did you do that?! I never summoned something that strong and big!"

"Because you wouldn't dare trade so many lives for one beast," Claude replied, never breaking eye contact with the destruction. "But I would."

The beast thundered across the field, tail swiping formations like children's toys, acid breath reducing units to bubbling sludge.

Fear spread faster than fire. Commanders shouted, orders broke down, soldiers fled and their banner were melted under the devastation the monster bring.

Vega folded his arms. "That's one way to thin the ranks."

Lyra watched with disturbing calm. "They're not even fighting back."

"They can't," Carina murmured. "Not when morale's already dead."

Claude finally turned away, the beast's rampage still echoing in the distance.

"Half is enough," he said coldly. "Let the rest crawl back to their capital. Let them spread the story."

He looked back at his children, all of them quiet now.

"This is your first war. Remember it well. Because next time... Or when you are ready, you will be the one who hold all the command."

When he returned to camp with his children, a wave of applause erupted from the soldiers. Cheers rang through the air, filled with awe and pride.

"That was a majestic creature, Your Majesty!" Samson grinned, clapping with genuine admiration.

"You wiped them out just like that! They didn't even have a chance to fight back. Bravo!"

Claude gave a slight nod, the corners of his lips lifting faintly. "You flatter me, Samson. But I'm not the only one you should be watching."

He placed a hand on Antares' shoulder, then gestured to the other children. "Bring them with you. Let them see more of war—of strategy, command, and consequence."

"Of course, Your Majesty!" Samson bowed deeply.

"It would be my honor to entertain the young lords and ladies! I'll show them the cacodemons we've enlisted and the siege formations we're preparing. A perfect learning experience!"

As Samson guided the children away, already launching into excited explanations, Claude turned and made his way toward his personal tent.

Inside, he was greeted by the soft laughter of a toddler and the warm voice of the woman waiting for him.
