Ren remained agitated as he merged with the earth, moving through the soil as if it were water. But instead of heading toward the established routes that led to the safe tunnels, he decided to go directly downward, entering unregulated zones where the risks were greater.
It made sense if he didn't want to be followed. While his two guards could track him, at least they never got too close unless he called them.
He didn't want to be near people right now. So he wasn't going to follow the "safe" routes he himself had helped establish.
The tunnels covered by living minerals that most students and miners now used were an innovation that had emerged after several tamers developed living tunnels using Ren's published methods.
The material covering the walls of these tunnels was mobile and resistant and formed effective barriers against Deep Assassins, the most dangerous creatures that inhabited the bronze-rank mana density zones underground.
