The Bloody and Crazy Apocalypse, Will the Abnormal Me Become Normal?

[Blood-like cross + pseudo group portrait + strong woman + growth + decisive killing + apocalypse + no superpowers + zombies] Chu Yunsheng claimed that she was a perfect perverted murderer. When she was about to kill the second person, the end of the world came. At that time, they were on the train. Train to Busan? The people in the carriage have mutated, where should they go? She was not scared, but felt very excited! The world has gone crazy, and it seems that killing them will be more exciting. In this world, it is enough for me to be a pervert. You all go to hell! I'm going to kill you all! Live! Just the thoughts of ordinary people. (The heroine is not a normal person. If you mind, you can view it from the perspective of other characters)
