Miniature Communication Magic Cubes had been installed between every oasis outpost on the desert side.
Through the communication links provided by the Miniature Communication Magic Cubes, news from the front lines soon reached Zhou Xu's ears.
At this stage, the two confirmed potential threats to Great Zhou were the Sea Race led by the North Sea Dragon Palace and that unknown desert faction.
Whenever something happened, there was a high probability that one of those factions had made a move.
As far as that was concerned, Zhou Xu had already braced himself in advance.
But the fact that the desert faction was made up of the Undead still delivered an unexpected shock.
It had also been mentioned that the enemy had two top Undead experts, one in the Vertical and Horizontal Realm and the other guaranteed to be in the Out-of-Body Realm.
As for that Undead expert guaranteed to be in the Out-of-Body Realm, Zhou Xu could basically confirm that the opponent was, at most, at the peak of the Out-of-Body Realm. Their strength could not be any higher.
Yalveth had caught a glimpse of the opponent using a possession technique to reach the front lines.
Through Inherited Wisdom, Zhou Xu had long since confirmed that the realm after the Out-of-Body Realm was the Clone Realm.
Once one reached that realm, they could directly condense a clone and station it somewhere else. Then, with a mere thought, their soul could rapidly transfer to wherever the clone was.
If the opponent had reached the Clone Realm, why would they need to resort to possession?
Even if their clone happened not to be there, forcing them to use possession and consequently weakening their strength, the gap of an entire major realm still remained. It would not be realistic for them to retreat
