Third Person's POV
A moment later, three thin blue lines suddenly appeared upon the wall before them. The glowing lines spread outward and connected together, and gradually outlined the shape of a door.
Seeing this scene, Ethan's eyes narrowed slightly.
The entire mechanism had been activated without using mana.
This was clearly a hidden passage built upon mechanical engineering rather than magical principles.
Such a thing was exceedingly rare among mages who preferred solving everything through magic.
More importantly, it meant that detecting this hidden entrance would be incredibly difficult for anyone relying solely upon soul sense or mana perception.
Elis raised her hand once more and used her mana to draw a glowing six-pointed emerald star at the center of the outlined door.
The moment the final line was completed, the hidden door slid silently aside, and a brightly illuminated tunnel appeared beyond it.
