A Strange Legendary World

I was born in Luoxia, which was just a fairyland-like place with birds singing, flowers fragrant, rabbits and deer running all over the ground, and simple farmers. Until I was eight years old, I watched my friend go mining in a distant place because he had no money and never came back. By the time we found him, he had already left. The zombies turned into zombies, and I thought that I should become stronger and kill all the zombies to avenge my friends. When I became stronger, I learned that there is a different world outside, and there are more dangerous killings, and I also inexplicably embarked on that killing path. Do I have a future? What will happen to my future?
