I'll Accept Your Challenge!

At Saint 8-dan Dimension Sundering realm, cultivators would gain the ability of Dimension Sundering, allowing them to temporarily isolate spaces from the world and establish dominance over it. This ability would usually be manifested in their Dominion, and it would completely sever any telepathy links, making it impossible for other cultivators to even communicate remotely with their weapons within their sphere of control. At the same time, any attacks that were launched into the Dominion would simply run out of control, like a boulder being thrown into the sea.

To draw a comparison, if one could be said to have gained a primary control over the space around them at Grand Dominion realm and Phantasm Space realm, at Dimension Sundering realm, their strength would have already fully matured, granting them the strength to create their own personal space!

As long as they willed it, they could steal a space from the world and establish their dominance over it!
