With earth runes circling around him, the leader, Goku, continued forward. Langrum and Almin descended slowly into the abyss along with Ruri, who was sulking and refused to climb onto the whale's shoulders.
The edge of the abyss was occasionally a steep cliff and sometimes a steep slope. To avoid making noise, everyone descended very slowly, and the laws of the Earth used by Alm and Bruno helped keep the ground firm and reduce the noise.
When they were already a hundred kilometers down, the whale stopped as he sensed something on the ground nearby. Then he called Ruri, who approached slowly, and asked her to cover him with her mental energy. She sighed and reluctantly obeyed, and then they dug a bit, and soon, the air around them changed.
'Dragon Glass! Excellent,' Bruno exclaimed mentally.
