Abel was stunned as soon as he entered the door.
He was in a huge cave, but all the walls were smooth like a room.
The area was 40 meters tall and covered thousands of square meters. There were also countless magic circles around to support it from collapsing.
However, what stunned Abel the most was what stood within 20 twenty meters tall iron puppets.
Abel saw many puppets in the past. Frankenstein's body, for example, was a human-size puppet.
He also encountered some 10 meters tall puppets, but they were all nothing compared to what stood in front of him.
Not because of the height, but the material.
As a grandmaster Blacksmith, no one in the world knew more about materials than him. He could clearly tell they were the materials of his battle forts, an ancient wall machine.
Those 20 giant puppets were the remains of ancient wars, and they were most likely used in the front line considering their heights.
