Ling Tian had successively defeated the Jade Devouring Sky Python, Chi Xue, and Po Tian, and had done so almost without a hint of suspense. This made the cultivators of the God Realm realize just how powerful he was. For a time, his fame in the God Realm was unmatched, and the title of "the strongest below the sixth tribulation level of the Quasi-Sage Realm" rang louder than ever.
They had also seen just how strong Ling Tian was. Most importantly, they had seen that he still had strength to spare. So most of the cultivators who had been preparing to capture him alive gave up on that plan. They had no idea whether Ling Tian was still holding back a trump card, and if they couldn't capture him, challenging him would be pointless.
For this reason, although Ling Tian took his turn guarding the arena, no cultivators came forward to challenge him. That included even ordinary Quasi-Sage experts, since most of them had already challenged Wu Ling while he guarded the arena, and all had ended in defeat. This also showed the benefit of having Ling Tian let Wu Ling fight in his place: at the very least, it saved Ling Tian a lot of trouble.
Even if a few Quasi-Sage experts did step up to fight Ling Tian, they wouldn't cause him much trouble. He could use his control over the energy of the surrounding void to suppress them, then combine it with his Phenomenal Domain to easily immobilize cultivators of the first or second tribulation level of the Quasi-Sage Realm. Defeating them would naturally be a breeze, often taking just one move to decide the victor. Even against cultivators of the third or fourth tribulation level, he wouldn't need to exert much effort.
