Jiang Xiaofeng, inheriting Kiryu Sento's knowledge and intelligence, arrives in the world of Douluo Continent 3 carrying Pandora's Box due to the will of the author, Jing Dagon. Can he become the Kamen Rider Build he envisions? Humans and soul beasts have a fundamental conflict, fueled by a hatred that has lasted for tens of thousands of years. Can Jiang Xiaofeng reverse this situation? "I don't know if I can change anything, but I can't ignore it. I want to try, to change it." PS: I'm a complete newbie, so there might be many flaws. Please point them out if you have any questions. This book's setting does not follow Douluo Continent 4; I couldn't stand Douluo Continent 4, and the later settings are too contradictory, and... ridiculous. This is a Douluo Continent knight story; if you don't like that, please don't read.
