The information about the fanatic's base as well as the raid was made public.
And its instantly got attention of a lot people.
Almost all people that are current in the demonic kingdom will participate in the raid if not all people.
Why?
Well… It's a literally kingdom underground.
Not only that, the fanatics were pushed to the defense and many of their hidden entrances were "Discovered by the demon lord army personally." ….
Anyway.
Even if you don't participate in the main attack on their city fortress, you can still attack some key locations in their base and get contribution points. Not only that, you can attack that place from many different locations, so you don't need to worry about traveling.
Even people that are currently staying the Umil kingdom are even willing to go to the demonic kingdom to just join the raid.
Not only that.
