Zombies Broke Out, My Sister and I Fled into Two Buildings

The apocalypse was coming, and my sister and I fled into a community while being pursued by zombies. In the panic, we separated and ran into a building. The building where I live is full of kind old people, but the building where my sister lives is full of burly men. My sister was so frightened that she asked me to rescue her while there was signal on her mobile phone. But after I went out, I was pushed into the zombie den to attract my attention. Before I died, I saw with my peripheral vision that she could not escape and was buried in the mouth of the zombies. When I opened my eyes again, I was back before I entered the community. This time, my sister pushed me away and entered the place where I went in the previous life. I didn't say anything and ran into the building full of strong men. Looking back in the direction of my sister, I couldn't help but sneer. I want to see how long she can last in that building!
