From City Lord to Emperor

My name is Ron, I traveled through time and became the lord of a city, but I didn't expect that my subordinates would rebel as soon as the game started. But it doesn't matter, I can recruit heroes and increase the strength of my men tenfold. I can build military camps, and as long as you give me resources, I can have unlimited troops. I can climb the technology tree, and the products I create are snapped up by others at high prices. Artillery and magic, steam and machinery, when the warlock controls the mecha and walks to the battlefield, the war wizard leads the giant beast and rushes to meet the enemy. The dead and the living are in the same city, and the evil dragon Gao Fei has an island to himself! I spread love and peace to the world, but I don't know what happened. The city in my name was named: Holy City, City of Light, Last Stand, City of God. And I am also called: the Supreme City Lord, the Supreme Saint! This novel and its characters are purely fictitious.
