The areas near the holes were already barren. When the underground creatures came out, they brought out all kinds of mysterious mists that killed all the plants nearby. Currently, those areas were entirely lifeless, with no animals or plants. All that could be seen was the devastated lands.
However, the mists had stopped coming out of the holes soon after the underground creatures left. Therefore, the environment didn't continue worsening. The area hundreds of meters in radius around each hole had been turned lifeless, but outside that range, everything had been staying the same as usual.
This time, however, the sparkling red-purple mist spread along with the wind. It soon covered about a thousand meters in radius and was still spreading to farther areas.
