After Passing Through the Book, the End of the World Has Come

The book that this book travels through is not an apocalyptic novel. The apocalypse comes after the protagonist travels through the book. The protagonist in this book does not like to communicate with others but there is a loli heroine. This book is decisive in killing and not the Holy Mother. There are not many plots about the protagonist after traveling through the book (almost none). Most of them are about Chen Xiao, the person who travels through the book. Chen Xiao had two systems at the beginning, one for killing monsters in the apocalypse and getting treasure chests, and one for the villain system that is necessary for book wearers (this is not very useful, Chen Xiao will scold it and unbind it at the beginning) PS: I don't know what to say. I hope the readers will forgive me if the newcomer's new writing is not good, hehehe.
