Graveyard
The secret realm was in chaos after the words were heard, everyone began to run desperately to avoid the most powerful enemies and attacking the weak.
As there were billions of people within the secret realm, the number of skeletons that came back to life was eighty percent of the number of people in the place. That was an absurd amount.
The most unlucky group was the one who was next to the three skeletons that were level 999, the moment these skeletons came to life, it killed all those around. For the killing to be diverse, the skeletons were far from each other.
Those who were at the highest levels such as 800 and 900, they asked the younger generation to search the door as they fought the strongest skeletons, leaving the weak to others.
The younger generation began to separate while using flying equipment such as flying swords or carriages, but the problem was to look in such a gigantic location would be extremely difficult, even with billions of people in the place.
