Leon was 'swimming' three meters underground, like a fish in the water.
His Spirit energy went through the dense fog of Earth Elementium surrounding him, showing him the surrounding earth. Twisting roots of old trees; coarse sand and rocks; wriggling insects; gophers hiding in their nests; rotten tree branches, and some other unidentifiable things...
It was only a short journey, but it allowed Leon to glimpse a completely different world that had always been right under his feet. In this secret world, Leon was like an untouchable king overlooking his kingdom, not caring about anything. If he really wanted to do something, with just a command, Demon Alligator Hunter would be able to wreak havoc in this place.
Although he wished he could spend a little longer traveling underground, but after merely seven to eight minutes, he could no longer stand it anymore.
It was not because he had depleted his Spirit, but because he was out of breath.
