The first trial copy of "The Battle of Jutland" allowed everyone to see what a real naval battle was for the first time. What is the real giant ship and cannon doctrine! In the second test copy "Verdun Meat Grinder", Ye Chen allowed people in this world to see for the first time what it means to be a million-person battle and a war as cruel as a meat grinder. The third one...... As Ye Chen continued to improve the map of "Earth Online", everyone saw one extremely difficult dungeon after another. Just when everyone thought that Ye Chen had exhausted his talents, everyone discovered that the previous dungeons were just appetizers, and the real super hell level difficulty dungeon had just begun...
