An ordinary person, an unknown system, and a god-slaying weapon powered by thoughts descend upon the world of Douluo Continent, a world of martial souls. What kind of waves will this cause? Douluo 1 (dodging the plot) - DXD - Douluo 2... PS: This book is slow-paced, doesn't rely on the system, and isn't a dragon-overlord type story. Please feel free to comment if you have any ideas.
