An unknown virus attacks, and the university campus that used to be full of books turns into a zombie-infested prison overnight. There are no heroes from the sky, just a group of ordinary college students trapped in the ivory tower. From huddled in the dormitory, fearing for survival, to holding on to crude weapons and fighting side by side, they pulled human nature between hunger, suspicion and the tide of corpses, and tried their best to protect the people around them in the apocalypse of collapse. The road ahead is dark, there are endless zombies, and the world will never return to its past. But keeping your companions and surviving hard is the most precious hope in a desperate situation.
