The Iron Throne: Conquer the Other World from the Flintlock

World background: Solas continent, a typical world of swords and magic, where magicians have a high status, knights are the main force on the battlefield, and the divine power is strong. However, magical power has the characteristics of monopoly, being controlled by the nobles and the Holy See, high cost (rare materials, talent restrictions), and slow development (reliance on ancient books and bloodline). The social structure is similar to that of the late Middle Ages, with multiple kingdoms, principalities, empires, and small lords in between. Protagonist (Lynn): A doctor of modern engineering, a top mechanical engineer, a military expert and a historical military enthusiast, who traveled through time due to an experimental accident. He became the heir to a remote, barren, and on the verge of bankruptcy as a small baron on the border. The territory may face problems such as infestation by monsters, banditry, harsh climate, threats from neighboring countries, exorbitant taxes, etc. The population is sparse and ignorant. Where will Lynn go in this hellish start? … Many years later, Lin En not only became the master of the continent, but also led the entire Solas world into a new era of technological civilization, setting his sights on the stars and the sea. As the empire flourished, Linn stood in a high tower, overlooking the brightly lit industrial city and the railroad tracks being laid, looking at the new order established by the empire.
