Xu Xin and the other two followed behind Keke.
At the same time, they were observing these machines around them.
"What do you think these machines are for?"
Li Wenxi asked, puzzled.
"They look so strange..."
These machines were much smaller compared to the huge machines Xu Xin and the others had seen before, which were used to process scarlet crystals.
Each machine was two meters tall, standing upright.
It was like a series of tall tombstones.
But they weren't made of stone, they were made of metal.
Moreover, each machine had different patterns on it.
These patterns weren't engraved but were composed of densely packed dark red spikes.
The spikes were at least five to six centimeters long, and looked extremely sharp.
The areas without patterns were composed of relatively shorter and thicker black spikes.
Every machine looked like a porcupine, covered entirely with spikes from top to bottom.
