This is the story of an ordinary doctor who only survived the apocalypse for three months in his previous life. He was reborn twelve hours before the apocalypse and returned to the countryside to fight zombies with humans. Use gas cylinders as bombs, find sulfuric acid from the school's chemistry building, and then get it from the firecracker factory in the town... Although there are no thermal weapons in the countryside, the people have their own unique survival wisdom! ! ! PS: Please collect it, it's so cold that even the cold authors dare not open the backend!
