The End of the World: Killing and Becoming a Hero

[This novel has been eunuch] When the apocalypse comes, others will get nothing by killing monsters, but Chen Yang can become stronger by killing monsters... The law of the apocalypse: The strong are not guilty, the weak are, the world is intertwined with darkness and despair, this period, humans call it the "dark period" PS: The introduction is weak, [lots of poison, sorry! ] This book is also called "Killing to Become Stronger in the End of the World". The protagonist is not a good person. I didn't say there are zombie works in the parallel universe. Also, the zombies I compiled are different from what everyone knows. If you don't like them, don't bother me. Note: Zombies are just a type of monster.
