Ten Years After the End of the World, My Dog ​​Is the Zombie King

At the end of ten years, I went back to pick up my dog. On a snowy day, the dormitory door was opened, and my dog ​​was lying by the window with his back to me, his front legs resting on the window sill. Then it spoke: "Finally..." I thought it was an auditory hallucination. Until it turned around and I saw a human face. Tentacles protruded from its mouth and it said, "I am a zombie." I thought I was going to die. But it didn't eat me. It said: "You are marked." Then I heard a voice in my head - it was from a zombie. Thousands of them. They are waiting for me. Waiting for someone who can become their new king.
