The Grand Duke's Son Is A Heretic - Chapter 139:Infiltration[II]

In a fantasy world ruled by kings and queens possessing great magical power, Kant Icurus Maybale is the only prince on the Aceaton Continent who does not possess magic. However, what he does possess, that nobody else does, is his past memories of the time when he was a Mechanical Engineer on Earth. With nothing but knowledge, brains, and wisdom, he dares to bring this medieval-esque fantasy world into the industrial era, and gain unimaginable wealth and power. Along the way, powerful forces that feel threatened by his rise in dominance will do whatever it takes to bring him down! Will he be able to conquer the continent, and potentially the world, to usher in a new age, or will he get crushed by the existing world order?

The world changed the day that cracks appeared in the sky– suddenly monsters named『Demonic Beasts』appeared and began to rampage, attacking people.

Meanwhile, girls called『Magical Girls』began to appear to counter the demonic beasts. As they defeated the demonic beasts, gradually people’s lives gained a semblance of composure.

–but when there is light, there is also darkness.

In the corner of an alleyway, a boy who had been attacked by a demonic beast was dying. His voice begging for help did not reach anyone and his body refused to move.

「Boy. Do you want to be saved?」

Looking into the boy’s face, a black cat began to speak to him.

The boy nodded firmly to the devilishly sweet invitation, in response the black cat mocked him.

「Is that so—then I’ll【Haunt (Save)】you」

—on that day, a『Magical Girl』was born in a place that no-one knew.

『She』never laments, no matter what the future may bring.

When Yohan woke up in the morning, he had a beauty in his lap and in his bedroom. It was like a dream come true for him until reality struck him.

It was then he remembered that he had been cursed by a goddess in the game he had been playing before sleeping. In his sleep-deprived state, he had offended the goddess and as a result, he had been cursed to become a 'no-good' man who could only provide 'support' to the 'heroines' of this world.

Thinking nothing of that curse beforehand, Yohan went to sleep, only to find his world-changing from that day onwards. His normal and mundane life was no longer going to be as such as more and more fantasy creatures began to show up.

And a female voice awoke him with a notification

*Ding dong ding.

Congrats on unlocking the fiction system. From here on, the user will experience the full scope of the logic of the fiction world. May the user use his PP and conquer everyone.*

And it was then Yohan realized - he was no longer in a world governed by science but one that followed the laws of magic. And the only way to survive was to utilize these so-called 'laws of fiction' to his advantage.

And the best and worst part of it all? The more he let his desire go, the stronger he became.

William Valehart was the absolute—supreme god of all existence. He ruled not a world, not a galaxy, but everything. Unbound by time, space, or death, he was omnipotent, eternal… and alone.By his own will, he sealed away his infinite power and chose to reincarnate. Not in defeat, but in search of something more. He boarded a world-sized ship and cast himself into the unknown, embracing mortality.He died—and awoke again.Reborn in a new universe, aboard the same titanic vessel, William finds himself in Urenus, a galaxy far larger and richer than the Milky Way. It’s here that a portion of humanity—just 5 to 8 percent of its population after conquering over half the Milky Way across millennia of war—has arrived through a now-vanished wormhole. Cut off from the rest of their civilization, they’re stranded, under siege, and barely holding out.Urenus is not unclaimed. Native civilizations, empowered by mana and superior numbers, have rallied against the human invaders. Advanced mech pilots are humanity’s last hope—warriors who push past mortal limits—but they are too few to win.That’s when William Valehart intervenes.With fragments of his sealed power awakening and his god-ship still under his control, he saves a human fleet from destruction—and learns of their fragile, desperate stand.He makes a choice.Not as a god who demands worship.Not as a savior bound by duty.But as a force reborn—who will fight beside them, reshape the war, and carve a place in this new universe.Because he can
