Small Communication Transfer Formations always come in paired sets; they can be used to communicate over long distances, but the communication still relies on the Transfer function to work.
You can transfer letters and Jade Scrolls back and forth to achieve the purpose of keeping in touch.
Now, however, Ye Zhen's Small Communication Transfer Formation can't connect to the one over in North Sea County, which leaves only one possibility—space has been locked.
Because the Small Transfer Formation on the North Sea County side is under constant watch by dedicated personnel; they might not be able to contact Ye Zhen immediately, but Ye Zhen can absolutely reach them anytime, anywhere.
At the same time, to carry out this kind of spatial lockdown doesn't mean that Xuan Sheng and the others are sealing the space of the entire Primordial Continent.
On that point, even if they possess an Innate Spiritual Treasure, they still couldn't pull it off.
