Small Communication Teleportation Arrays came in matching pairs and could communicate over great distances, but their communication was still realized through teleportation.
They could teleport letters and jade slips back and forth, achieving the purpose of communication.
Now that Ye Zhen's Small Communication Teleportation Array could not contact North Sea Commandery, there was only one possibility—space had been sealed off.
That was because the Small Teleportation Array on the North Sea Commandery side was guarded around the clock by dedicated personnel. They might not be able to contact Ye Zhen immediately, but Ye Zhen could absolutely contact them anytime, anywhere.

Even with a Xiantian Spiritual Treasure, they could not accomplish that.
And if they truly did that, it would be a heaven-shaking upheaval.
As long as they sealed off the space within tens of millions of li around the Yizhi Sand Sea, they could achieve this effect.
Outside the Yizhi Sand Sea, everything remained normal.
