At this moment, only one question lingered in Emperor Di Xuan's mind—though all had refined their Grotto Heaven to achieve the status of a great emperor, why was the disparity between them as vast as the clouds and the mud on the ground?
Especially Su Jie's Grotto Heaven—it was something he had neither seen nor heard of before. His own knowledge did not include such an enormous Grotto Heaven in the Tianyuan World that could be refined.
An image of a towering giant, eight thousand miles tall, was simply astonishing.
The typical emperor's Grotto Heaven was usually only a few hundred miles in size. For instance, Emperor Di Xuan's was just over a thousand miles at its strongest. But eight thousand miles? Not only had he never seen it, he had never even heard of it!
"What kind of Grotto Heaven is this?"
Emperor Di Xuan knew there was a significant gap between him and Su Jie, but he hadn't expected it to be this immense.
