This Cthulhu Is a Bit Reckless

My name is Wang Mang, and I am a pig butcher. In troubled times, demons are rampant. The Righteous Immortal Sect says that those things are the result of resentment and can only be eliminated by using Taoism. I don't know what Taoism is. I only know that there was a talking black mist that wanted to eat me that day. When I stabbed it in, it dispersed like a fart. Later, an immortal came to me and told me that I had the mark of the "old days" on my body, that I was the chosen one, and that I was more terrifying than any monster. I didn't understand what "old days" meant, but I saw him staring behind me and trembling. I turned around, looked at the meat ball floating in the air and covered with tentacles, and kindly introduced: "Oh, this thing, I raised it, and it's called Ah Huang. Although it's ugly, it doesn't bite, really." The immortal went crazy.
