Ever since Venerable Sword Saint had seen Ling Tian use Intent Power to influence and control the Circulatory Universe, he had coveted it and wanted to make it his own. He believed it would greatly increase his strength, especially when he eventually tried to break free of the Lord of the Universe's constraints. He was determined to obtain this secret technique, and the only way to do so was to capture Ling Tian alive and search his soul.
In Venerable Sword Saint's mind, the reason his two attempts to attack Ling Tian and the others had failed was naturally the Myriad Sword Demon Extermination Grand Formation. Without it, he was confident he could easily kill Ling Tian and every cultivator around him. But he believed Ling Tian would never leave the Fengyun Realm and give him such an opportunity, so he could only wait until he had fused with more golden cores before attacking Ling Tian again. After all, he was quite confident that fusing with golden cores would make him far stronger than Ling Tian and the others.
But Venerable Sword Saint suddenly sensed that Ling Tian had left the Fengyun Realm. At first, he thought Ling Tian was deliberately toying with him. Though he was excited, he did not act rashly, instead deliberately waiting for several centuries. All that time, Ling Tian never returned to the Fengyun Realm, and he kept moving farther away from it. This left no doubt in Venerable Sword Saint's mind that Ling Tian wasn't toying with him. In particular, he sensed Ling Tian attack several times during that period. Venerable Sword Saint could sense Ling Tian's aura, and thus could sense other people's auras as well. He also knew quite a bit about the relationships among the major powers in the God Realm,
