πI recommend to you the book,'National Familiar: All My Pet Skills Are at the Divine Level'. The main character's talent in this novel was super funny. Moreover, everyone could awaken their own pet and awaken their talent. The talent that the main character awakened was the ultimate talent beyond SSS-rank, which could upgrade all the skills of the pet to divine-rank. The length of this novel also meets your requirements. It has more than one million words, and the writing style is very simple and easy to understand. It is suitable for readers at the junior high school level. I hope you will like this book.π
