They Ended My Apocalyptic Solitude

(Abbreviation: The End) My name is Xia Mi. In the zombie apocalypse, I died in the hands of the people closest to me. I will live another life. I will not trust anyone! I prepared supplies ten years in advance and built a seventeen-story building in an uninhabited suburb. I only had Golden Retriever Bruce by my side, and there were countless CDs and novels... This time, I won't trust anyone! Wait, what the hell is this system? Let humans who enter their own buildings complete phased tasks and obtain building upgrade cores? I didn't have this in my previous life! The last month, the blood moon is coming, and zombies are rioting... I didn't have this in my previous life! A girl who accidentally entered the living room suddenly appeared... I had this in my previous life. The bullet was loaded with a click, and the Type 54 pistol was pressed against the girl's forehead. The metal body reflected Xia Mi's cold pupils. "In this life, I will not trust anyone!" ———————— "October 7th, cloudy. It has been a month since the zombie crisis broke out. All the food has been eaten. I have to go out to find food!" "October 10th, sunny, so lucky! There is a tall building in the wild, with water, electricity and food inside, but no one is there yet!" "October 10th, Yin, I was caught. He had a gun. It was so scary. What would he do to me?" "On October 10th, Yin, he asked me to dance?" "..." "October 1st, Qing, he said he doesn't have to dance anymore, but if he doesn't dance, he will be very sad for the rest of his life."
