The Apocalypse Survivor

Well one day, zombies appeared everywhere on Earth. Everywhere. And it's not only zombies but countless bunch of mutated beings. Here our MC, a sword enthusiast, was suddenly plunged into a world of monsters, killing, bloodshed, betrayals and all that classic stuff. The MC even has a book, which for my convenience, has unlimited pages, in which he will apprantly write his daily life and what all happened around him. Ps:- As the title says, this book will be written in the form of log/diary entry. Enjoy :)
