After the gamers experienced the opening Plot at the Ogre Fortress, they followed the Plot notice and returned back to their outposts.
The gamers of Eternal Kingdom received the subsequent mission:
[Mission Title: Start of the Ogre War
Mission Description: The Ogres rallied under the banner of Polio and had the dark power of the Void army. Our all-out attack on the Ogres was thwarted, but we will not give up. There is hope in the world. Be strong, warriors!
Mission Objectives:
Excavate in the Dungeon: 0/60 minutes
Submit organic materials: 0/10
Additional Objectives:
Submit war materials, Magic Stones: 0/10 (Can submit repeatedly)]
The gamers didn't know and dared not ask why they had to submit Magic Stones for the mission.
Fortunately, it was only an additional objective and not a compulsory objective. Only extremely rich gamers could perform this objective, like Arthur.
