Let You Develop Your Territory, Not Build Civilization with Your Bare Hands

Traveled through another world and inherited a noble territory. But before Annan could be happy, a group of robbers came to the door. In an emergency, bind the lord system. Hundreds of horse thieves? With a Mosin Nagant and my god-level shooting skills, I will carry them all away! Someone starts a war? Sorry, your heavy infantry is very strong, but my steel torrent is totally unreasonable and will crush them all! Church? Alien? God? No matter what opponent you are, as long as you dare to take action, you will be carried away. Several years later, Annan looked at the war weapons in the sky and fell into deep thought. I obviously just want to develop my territory, so how can I create a technological civilization? This novel and its characters are purely fictitious.
