God Of Monsters System

A 24-year-old man woke up in a void when he went to sleep. Arc one-Long live summons. All the characters or World background and character dialogues goes to (Xia Fei Shuang Jia) I only put my own twist on so please check out the original source(Xia Fei Shuang Jia). Arc two-??? I am a beginner writer, so, please don't mind if there are some basic mistakes especially some grammar and sentence structure. Ps: I do not own anime, manga, and novels mentioned in this novel I only own my OC or OC's. This is just a fanfiction:) I don't own the book cover, so if anyone has issues about it let me know :)
