It wasn't that Lu Xiaotian planned to face the grand formation head-on. With his current strength, he still couldn't afford that. Rather, using the Void Sky Sub-Cauldrons as his support allowed him to avoid a considerable portion of the impact from the formation's power.
With the Void Sky Sub-Cauldrons, Lu Xiaotian moved much faster. He no longer traveled in a straight line in one direction as he had before.
What they had thought was a straight line wasn't straight at all. It was merely an illusion created by the grand formation, one that Lu Xiaotian and the others had been unable to detect.
Venerable Shengyang's calculations had indeed been formidable. But no matter how meticulous his plans, he could only base them on the information available to him, such as the strength of the seven experts in Lu Xiaotian's group. In that regard, he had them completely figured out.
But he couldn't have foreseen that Lu Xiaotian had gained considerable insight into the attacks generated by the Sacred Soul Sword Stele through his Lotus Avatar, or that he possessed a treasure as rare and precious as the Void Sky Sub-Cauldrons.
Lu Xiaotian's true body had already refined two of the Void Sky Sub-Cauldrons. He had considerable experience using them, and mastered them far faster than anyone expected.
With Lu Xiaotian's current cultivation and such a treasure in hand, finding the edge of the formation was no longer difficult. The hard part was that the formation's defenses were extremely powerful. Even if Lu Xiaotian discovered the boundary on his own, he would have no way to break out.
But there were still six other old monsters behind him, weren't there? If there was one thing Venerable Shengyang had overlooked, it was that he had bitten off more than he could chew.
