In the well, there was a flickering bolt of lightning. It was different from normal lightning, and the end of the bolt seemed to be stemming from something solid. It was a blue stone.
The blue stone was like crystal, and he could see lightning inside and out of it.
The lightning was strange, though. Each flash only illuminated a small portion of the area around the stone. Outside of its immediate proximity was darkness and nothing more. If Han Sen had not been led as close as he was now, he wouldn't have been able to make it out in that stifling darkness.
Water Fairy had generated a bubble for Han Sen to sit within, so he could breathe and talk underwater.
"What is this thing?" Han Sen asked as he pointed towards the lightning stone.
The lightning stone was very large, around the size of a house. Curiously, there were many holes in its exterior that could provide Han Sen access.
