Cheng Yan, a modern engineer who died from overwork, awakens in the body of Roland Wimbledon, a disgraced fourth prince in a medieval kingdom where "witches" are feared and executed as spawns of the devil. Also known as *Fangkai Na Ge Nuwu*, this saga begins at the foot of the gallows when Roland defies the fanatical Church to save Anna, a young witch sentenced to death for her supernatural fire. Thrust into a cutthroat war of succession against his ambitious siblings, he must transform a desolate border town into a thriving industrial bastion. Roland faces the daunting challenge of reconciling his twenty-first-century scientific mindset with a world steeped in superstition, all while protecting a growing union of witches from a society that demands their blood.

The gears of fate shift when Roland discovers that magic is not an occult curse, but a potent physical force that can be revolutionized through the laws of physics and chemistry. This realization ignites a breathtaking industrial revolution, arming his subjects with firearms and steam engines just as the terrifying Demonic Beasts and an ancient demonic threat emerge to annihilate humanity. As the stakes escalate from a simple throne room struggle to a grand battle for the survival of the human race, Roland’s resolve never wavers. Driven by the dream of building a modern civilization where science and sorcery coexist, he fights to create a world where no witch has to hide in the shadows and where human progress is the ultimate weapon against extinction.
