I'm Looking for the Truth in the End

The world has changed as soon as I wake up Because the outbreak of an unknown virus has caused the world to become rampant with zombies, Before the zombie outbreak, Xia Jinan went to see his sister for dinner as usual. However, her sister had a serious look on her face and told her to go out less recently and stock up on durable food, and to strengthen the home quickly. Jinan felt weird that she refused to answer even if she asked her questions. The day before the zombie outbreak, Jin'an received a text message from her sister, saying that she would be in seclusion in the near future and could no longer contact her, and asked her to keep their relationship a secret. Jin'an realized that something was wrong, and the other party's phone had been turned off after calling her. The first place where zombies appeared was the Second Hospital, and next to the Second Hospital was the research laboratory where her sister Xia Wen'an worked. Jin'an felt something was wrong and drove to the research institute where her sister worked. However, the research institute and the Second Hospital had been overrun by zombies.
