What's Wrong with Building a Steel Torrent in a Dungeon?

The industrial development plan of the black-bellied and venomous loli! Because she died suddenly after listening to a crosstalk, Fran traveled to the magic world and became a glorious nun. But she wanted to start a magic journey, but she became a captive of the goblins. Other people's journeys are full of adventures and golden fingers? Why is it that I am targeted by various forces? Since the gods don't love me, the demons don't love me, the human race doesn't care about me, and the elves won't save me, I can only rely on farming! Build a tank! Build a Gundam! Destroy this corrupt and dirty old world!
