The protagonist Zhao Xiaole lives in a low-income city. He lives by picking up garbage every day. His family environment is relatively poor, but he has a dream of becoming a mechanic. Mechanics produce weapons and mecha units that destroy zombies. It is a very promising profession. Brother Zhao Daxi is a doctor who treats infected people. He is actually responsible for feeding them some cheap and useless medicines and finally getting rid of them. Zhao Xiaole went to the guard school in the city with difficulty. I met my good friend Anshun there. Anshun's sister Yili likes Zhao Daxi, so she treats Zhao Xiaole very well. Zhao Xiaole met Xiaoye, a girl who was as poor as him at school. She had many special qualities and was very kind to Zhao Xiaole.
