Changing (II)

A few months after the ones with abilities came out and defeated the monsters, everyone started to talk about the dungeons. 

Dungeons would come down as the shape of them reminded Neban of a cave. The ones who entered the dungeons with no problems reported that the insides were either like caves or the building they took over. 

Not only did people mention the shape and insides of the dungeons, but they also talked about the entrance colors. Each dungeon's entrances consist of three different colors: green, blue, and red. 

It did not take long for the government to figure out what those colors meant. 

After that, the government started to set out more and more people into the dungeons to learn more while fighting the monsters because the people realized that those creatures would come out if the dungeon were left alone for a while.
