I Transmigrate into a World of Dungeons and Create Five Major Dungeons

(War scenarios + World War I + World War II + the Five Permanent Members scenarios + putting the Japanese in their place) Ye Chen transmigrates to the Fourth Planet, a world where anyone can create war scenarios. To his amazement, the people here have a shockingly poor understanding of warfare and an outdated level of military technology. So he decides to create Earth Online maps and give the world a little taste of the five great forces from Earth... no, the five great benefactors. For his first trial scenario, The Battle of Jutland, he shows everyone what a real naval battle looks like. What true battleship-and-big-gun doctrine really means! In his second trial scenario, The Meat Grinder of Verdun, Ye Chen gives the people of this world their first glimpse of million-man battles and warfare as brutal as a meat grinder. The third one… As Ye Chen continues to refine the Earth Online maps, everyone gets to experience one insanely difficult scenario after another. Just as they think Ye Chen has run out of ideas, they discover that the previous scenarios were merely appetizers. The truly hellish, super-hard scenarios have only just begun…
