I Serve as a Pendant for the Boss

I thought I had a system, but it turns out I don't. I thought I had a dog's, but I didn't. I thought I should at least have novice benefits at the beginning, but I still didn't. Until one day I discovered that the boss was by my side. Fortunately, I didn't run out of the safe zone at the beginning. Question: How do you survive in this mysterious, weird, twisted, crazy, and polluted world? Answer: Hold on tight, boss!
