Carrying a Gun and Bravely Entering the New World

No money, no house, no money! I suffered a lot of humiliation in my previous life just because I wanted to live a happy life again. When I woke up, I traveled to a new world. According to the novel's formula, would I be given a golden finger? What's not there? Then don't blame me for taking out a high-tech automatic rifle and beating you primitive people with cold weapons. This novel and its characters are purely fictitious.
