Industrial Revolution of the Mage Lord

... He created the Spellcaster Forum for the Magic Net, donning a mysterious administrator persona to fleece legendary casters for all they were worth; Utilizing the peculiar soul characteristics of a transmigrator, he successfully cracked the soul conversion technology that the Alchemical Exploration Society had craved for centuries; He purchased frontier reclamation permits from noble lords to build a vast wasteland territory of his own, quietly accumulating power and developing in low profile; Fully automated assembly-line magic factories, mass-produced magic-tech weapons, and the cultivation of a formidable army that transcended the era. ... The King and nobles coveted the wealth of his territory? How many waves of firing squads could their elite knight orders possibly withstand... The Church branded him with the crime of evil blasphemy? Then he would tie those charlatans to the stakes and execute them in public... Demons and savage orcs wanted to invade and plunder? Let them taste the ground-clearing fire of magic-power cannons... ... Hearing that the Spellcasters' Federation wanted to award him the highest honor in the magical world, Harvey smiled modestly. "I am just an ordinary Necromancer who happens to know a little bit about high-tier alchemy, life transmutation and soul conversion, extra-dimensional mana application, and the manufacturing of magic-power weapons... just some insignificant knowledge of magic technology."
