Apocalypse: I Can Summon a Dinosaur Legion

The author's writing is not very good. After reading for a while, I thought there were too few zombies. There were only five after a long time. The protagonist felt like a retard when he rescued the girl. She was frightened by the protagonist after being pulled out. At least she had seen zombies before. She was so frightened that she couldn't stand up. The protagonist pulled her and she pretended to be cold. When she saw the death of her classmates, she started crying again. When she left, her classmates turned into zombies and she didn't want the protagonist to hurt her classmates. I really cried to death.
