This cube was much bigger than the one that brought Xue An here, and its structure was evidently more intricate and complex.
When it floated there, it seemed as if everything paused.
Xue An slightly raised his eyebrow, "What is this?"
"The key!" Wan Han looked at the cube with a complex expression and said softly.
"The key?"
"That's right, it's the key to this world. It's the same type of tool as the cube that brought you here, the difference is that the cube that brought you here has much lower authority than this one!"
Xue An showed a thoughtful expression.
