A few hours ago,
The Warrior Association has already evacuated people from the danger zone. Unexpected situations appeared inside the danger zone. Except for people who can solve those all the other people need to evacuate.
Almost all the parts of the danger zone are facing this kind of problem. Suddenly the amount of dark energy somehow increases in that part of the danger zone and a strange Monster appears in that part of the danger zone.
Those Monsters are not powerful enough to put the life of every warrior in danger. But those Monsters are related to dark energy.
This is the reason the Warrior Association did not waste a single second to act. The good thing is that they have already taken care of almost all of those ghoul monsters.
It looks like the Warrior Association has overlooked the situation where normal Monsters from the danger zone are getting affected by dark liquid.
But some time ago, they received a report about this and this made the situation difficult.
