Apocalypse isn't a RPG

Hello dear readers, this is my first book and this book will be about a Badass-Mc that destroys everything in his path. The MC Johny Chaos will be the most time alone. He will not be OP as fu*k but he will walk the dark path. When the apocalypse finally arrived everyone will get a System (Game like Interface) No Harem No senseless family searching or something of that. If you have ideas for this novel, please leave a comment. Thank you for reading.
