大佬你头又掉了

As we all know, you can level up by killing monsters, and I am... that monster. As the only zombie on earth that can turn around and not die, I concealed my identity and kept a low profile as a zombie in order to protect myself. However, I was worried about my sick ex-girlfriend, so I secretly protected her. I didn't expect that my ex-girlfriend had become a female warrior who killed zombies without blinking an eye, and I was discovered by her? I wanted to escape, she wanted to chase me, we struggled and fell in love, and in the end you told me that the whole world had to die? Okay, I won't pretend anymore, I am actually a vaccine.
