Apocalyptic Police

The protagonist was originally a policeman. When the apocalypse came, he gave up after seeing the dangers of human hearts and the ferocity of zombies. Then when he woke up, he found that he was bound to the system, but he was not panicked because... He was still the same policeman! That former policeman!
