The Earth Element Bodies typically possess magic-like abilities, allowing them to walk through walls and burrow, but their nests also include many tunnels and passages.
Because walking through walls and burrowing require effort, using magic-like abilities consumes the power within Demon Crystals.
As Element Bodies, they should try to accumulate power and store it in Demon Crystals. Not only can it be used to handle emergencies, but more importantly, the power of the Demon Crystals can help them break through to a higher Life Level.
Da Dou drilled into the tunnel; the experience of fighting his way here was not pleasant.
He was a giant, extremely large in size, unable to stretch freely in the tunnel.
Actually, the tunnels and passages dug by the Earth Element Bodies were still decent, compared to the Dwarves' underground passages which were too narrow, stopping giants from stepping forward.
