Become a Wolf in the Wilderness

I woke up in a cold laboratory, the air was filled with the smell of blood, and genetic researchers were torn to pieces on the ground... But I couldn't think of anything. I ran out in fear, as if there was something dangerous behind me. Breaking out of the dark basement, what you see is a devastated city and streets. The world has long changed. I tried hard to find the shadow of the past in the ruins, but the only response was ugly monsters screaming and rushing toward me. I was so scared that I kept running. Only my voice calling for help echoed in the empty dead city.
