They were sparring on the open ground.
Gradually, as time passed, Duan Gujin found that he had a strong sense of the distance within ten meters around him.
"How do I feel like I've touched the edge of the Spatial Domain?"
Duan Gujin's eyes flickered, finding this too incredible.
He was not unfamiliar with the Spatial Domain, but he knew that at his current level of Cultivation, it was impossible for him to touch the edge of the Spatial Domain.
At first, he thought he had made a mistake in his judgment.
However, as he continued to spar with Seventh Imperial Uncle, forcing out his own potential, he felt more and more that he had indeed touched the edge of the Spatial Domain.
His mind raced, trying to apply the knowledge he had learned to his previous insights.
But very soon, he discovered that he couldn't apply his previous knowledge to his insights.
"Dizzy! What's going on?"
Duan Gujin took a deep breath; he tried many methods, but all ended in failure.
