Chapter 3: The Blueprint of Madness

The hours of scolding and words of disappointment from her parents did not shake Mireille’s heart in the slightest.

Letting the grating noise pass through her ears, she was finally released, and upon returning to her room, she quietly closed the door.

The sound of the door shutting was like a dry echo announcing the end of an old world.

The room, surrounded by luxurious furnishings, was nothing more than a “war room” for dismantling and reconstructing the world.

Sitting down on the bed, Mireille closed her eyes.

Inside her mind, a precise and intricate system blueprint began to take shape.

‘Phase one. Complete control of the ducal house.’

Her parents were now nothing more than “unnecessary variables” that needed to be eliminated.

She would not resort to something as crude as direct murder.

Without arousing suspicion from those around them, she would ensure their demise with certainty.

‘And then, I will thoroughly uncover everything—the ducal house’s financial state, the loyalty of its retainers, even its hidden debts.’

Mireille murmured inwardly, as if issuing instructions to subordinates from her previous life.

Her knowledge as a supply chain manager was perfectly suited to taking control of the “management system” known as the ducal house.

She began assembling concrete processes within her mind.

‘Phase two. Strengthening and enriching my territory.’

The ducal lands had failed to realize their potential due to corrupt nobles and incompetent administrators.

She would transform this territory into a solid foundation to support her “path of domination.”

The faces of serfs, left inefficient and neglected, surfaced in her mind.

Methods to maximize their productivity without granting them freedom began to take concrete form.

“If I introduce an incentive system based on output, I can draw out maximum labor efficiency.

That is nothing more than optimization to give each piece greater value.”

At the same time, by applying knowledge from her previous life and introducing firearms and technology, the territory’s economy and military strength would improve dramatically.

‘Phase three. Alliances and division among powerful nobles.’

To overthrow the royal family, allies were essential.

She categorized the nobles of the royal capital as “usable resources.”

Her criteria were not lineage or status, but ability, loyalty, and utility.

‘Those who harbor dissatisfaction toward the royal family.

Those who wish for their abilities to be properly recognized…’

Mireille would find such individuals and win them over with sweet words.

Meanwhile, those deeply loyal to the royal family would be weakened through division and schemes.

In her previous life, she had been nothing more than a powerless office worker.

But in this world, it was different.

By making use of her position as a duke’s daughter, she could obtain power.

This time, she would achieve perfection.

‘Final phase. The overthrow of the monarchy and the construction of a new world.’

Once she had acquired sufficient military strength, economic power, and allies—pieces to be used—she would march on the royal capital.

What she sought was not merely the usurpation of the throne.

She would destroy the very “system” ruled by the incompetent and rebuild an “optimized world” where only the capable could rule.

And at its summit, she herself would reign.

Mireille stood up, feeling the cold stone floor beneath her feet.

Beyond the window stretched the dark and silent garden of the ducal residence.

She muttered to herself.

“Anyone who obstructs my plans—and anyone who is useless—will be purged without mercy.”

From this room, her path of madness and domination quietly, yet surely, took its first step forward.
