I recommend the novel " Global Overlord: I Can Summon a Billion Races ". It tells the story of how the people of the world transmigrated to another world, and everyone became an overlord and established their own territory and country. The main character, Jia Huai, had a powerful army, established a powerful kingdom, and developed a powerful army to conquer the world on the glacier. Let's see how the protagonist will build a powerful feudal lord empire! I hope you like my recommendation.😗
