Beneath the sinkhole, a golden fire spread through the entire underground river. As the fire spread, the temperature rose gradually. The water in the underground river began boiling as if there were vile beasts fighting inside.
Eventually, the water in the underground river evaporated entirely, revealing the bumpy bottom. White mist rose into the air. Combined with the fire, it looked like the fire was burning clouds. Even the air became a little distorted.
Fire gathered from all directions as if they were worshipping something. If not for the thick walls and the layers of soil that were extra tough, the entire sinkhole might have collapsed.
There was an empty space in the middle of the sea of fire. There were no flames there at all as if the fire had entered a vacuum.
