Synopsis

Chen Yan travels between worlds, ending up becoming an honorable prince in a medieval fantasy world. Yet this world was not quite as simple as he thought. Witches with magical powers abound, and fearsome wars between churches and kingdoms rage throughout the land.

Roland, a prince regarded as hopeless by his own father and assigned to the worst fief, spends his time developing a poor and backward town into a strong and modern city, while fighting against his siblings for the throne and absolute control over the kingdom. Join Roland as he befriends and allies with witches and, through fighting and even farming, pushes back invaders coming from the realm of evil.

Roland’s success is based on his ability to bypass centuries of trial and error using modern theory.

Editor's Note

💡 The Pioneer of "Industrial Fantasy." If you've ever wondered how a modern engineer would fare in a world of knights and magic, this is the definitive answer. It’s not just about magic; it’s about thermodynamics, chemistry, and mass production. Roland doesn't fight with a sword; he fights with a 152mm Howitzer. It is a massive, completed epic that transitions from a small town's survival to a global war for the fate of species.

"Magic is just a shortcut to the physical laws of the universe. If a witch can create fire, she is a portable furnace. If she can manipulate molecules, she is a high-precision CNC machine."

*1498 chapters of steam engines, sorcery synergies, and solving world hunger with better crop rotation. Complete — and still the gold standard of industrial fantasy.*

Experience Curve

The Border Town Arc (Ch. 1–300): ⭐⭐⭐⭐⭐ – The "Golden Era." Pure town-building, introducing the first witches, and the first taste of modern weaponry (flintlocks) against medieval knights.

The Unification Arc (Ch. 301–800): ⭐⭐⭐⭐ – Roland expands his territory and the industrial revolution accelerates. Steam engines, telegraphs, and early airplanes appear.

The War of Will Arc (Ch. 801–End): ⭐⭐⭐ – The scale shifts to a cosmic/metaphysical level. Some readers find the "Dream World" and the "Divine Battle" sections more confusing than the early industrial parts.

WebNovelDB Review

9 /10

A masterpiece of kingdom-building. It makes learning about the Haber-Bosch process or the internal combustion engine feel like an epic adventure.

World-Building: 10/10. The author creates a deep history involving ancient civilizations and a logical reason for why magic exists.

Kingdom Building: 10/10. Unmatched in the genre. You see the progression from wooden spears to bolt-action rifles and beyond.

The "Science" Gripes: As noted in reviews, Roland is a "walking encyclopedia." His ability to recall complex chemical formulas and mechanical blueprints from memory is unrealistic (Mary Sue territory), but necessary for the plot's pacing.

Cons: The secondary cast of witches becomes so large that many are reduced to "power-up tools" with little personality later on. The ending is polarizing due to its shift away from pure science into metaphysical territory.

The Archetype: The "Tech Geek." If you love Civilization (the game) or Dr. Stone, this is your perfect read.

Not For You If: You hate "overpowered" protagonists who know everything. If you prefer high-stakes martial arts battles where the hero barely survives, the "one-sided" nature of guns vs. swords might bore you.

Archive Note: This series is Complete. It is a rare example of a long-running webnovel that actually provides a definitive ending to its world-spanning mysteries.

Ending Note: The final arc shifts from science to metaphysics. If you're here purely for the industrial revolution, you may find the 'Dream World' and 'Divine Battles' confusing. For those seeking closure, it delivers—but differently than expected.
