*WOO*
Angele heard some vibrating noises in his ears and noticed that he was standing in a dark tunnel seconds later.
He turned his head around, but the only thing he saw was a dark wall.
"A spell that took me through the physical barrier… It doesn't seem like an illusion," he muttered as he looked at the tunnel ahead.
It was an arched tunnel with glowing blue crystals on the top. The blue crystals lined up and released gentle blue light.
Angele started moving forward and reached the end several minutes later. It was a dark-brown cave.
In the center of the cave, there was a humongous silver ball around two meters tall.
Strangely, the metal ball was rotating slowly and there were several openings on it. Inside the ball, there were countless silver gears; the structure was quite complicated.
The mechanical parts were moving and reconstructing. Angele could see the glowing blue runes on each of the mechanical parts.
