Siheyuan: From the Start, I Grabbed a Hunting Rifle and the Whole Courtyard Panicked

I transmigrate into the poor son of a Four-Courtyard House family. My father was a war hero, and my widowed mother has two children. Everyone thinks they can walk all over us. From the start, Second Master tries to take advantage of my mother, so I pull out our ancestral hunting rifle. The whole courtyard is stunned, and I head into the mountains. My Hunter System activates, and from then on, there's meat in abundance. Everyone in the courtyard is green with envy. Silly Zhu asks where I got the meat. I grin. "That's none of your business."
