Zombie Apocalypse Chen Qiang

This is a story about the outbreak of a zombie virus. There is no system and in the apocalypse, how do civil engineers build a doomsday fortress? How do the surviving humans survive and reproduce? How to strengthen the shelter? How to make nitrifying explosives? How to fight threats? New works are released. Welcome everyone to read my works. I hope you will like them. Your attention and comments are the motivation for my writing.
