"Cao Bing!"
Within Chaos City, Cao Bing was meditating with his eyes closed. Around him, the Level 8 Formation he had named "Primordial" was continuously operating.
It was clear that this Primordial Formation had become far more refined than when Cao Bing had first set it up. With a single thought from him, everything within the formation would be under his control.
Moreover, as Cao Bing gradually perfected the Primordial Formation, he could even use the spatial abilities of the Profound Yellow Realm to form a formation with a single thought.
Of course, the prerequisite was that Cao Bing had to prepare some formation foundations in advance. Otherwise, he could not create a grand formation out of thin air.
Even so, Cao Bing was already extraordinarily impressive. Once this grand formation was activated, unless his opponent was a super expert like the Chaos City Lord, not even a Universe Master could hope to keep him behind.
Once the formation was deployed, even a Universe Master would be trapped within it and unable to break free in a short time.
Furthermore, this kind of formation possessed extremely strong concealment abilities. As long as Cao Bing remained within it, ordinary Universe Masters would be completely unable to detect him.
Even the Chaos City Lord would be unable to find Cao Bing within the formation unless he searched every inch with painstaking care.
If the Chaos City Lord had not been exceedingly familiar with Chaos City and absolutely certain that Cao Bing was in his courtyard, even he would have found it difficult to locate Cao Bing.
In truth, the Chaos City Lord was deeply shocked by Cao Bing's current state. He had not expected that after such a short time apart, Cao Bing would display yet another power that left him astonished.
