New World: If I Were Tielin, I Would Do This

I'm from the Secret Service. I have a gun. I can call a few of my men to work together at any time. I have an elder brother who is not a giant but can speak well in Nancheng. I also have a stupid younger brother. The city was besieged by a large army, and there was an undercurrent inside the city. The old legal system has collapsed. The new world is yet to come. This period of time can be regarded as the darkness before dawn. I think I can do something. Do something you've never thought of doing before. This novel and its characters are purely fictitious.
