With one Heavenly Slave killed, another appeared to take its place. This left Chi Xue and the others deeply frustrated. Although they didn't believe the Heavenly Slaves were infinite in number, the more that appeared each time, the harder it became to kill even one. At this rate, wiping them all out would take a very long time.
It made sense. Chi Xue and the others had spent hundreds, even thousands of years and lost five or six groups of more than ten temporary strongholds just to kill one Heavenly Slave. And that one had only been at the peak of Quasi-Saint Rank Seven. Killing a Rank Eight Heavenly Slave would be even harder. In other words, it would take them a very, very long time to kill them all—and by then, Ling Tian and the others might have reversed their golden cores once again.
Every time Ling Tian and the others reversed their golden cores, their strength made a qualitative leap. Ling Tian was already at the peak of Quasi-Saint Rank Six. After reversing his golden core six times, he would easily break through to Rank Seven, perhaps even the middle or upper levels of Rank Seven. At that level, he wouldn't even fear Rank Eight experts—a fact Chi Xue and the others had already witnessed. If things dragged on until then, killing Ling Tian would become more difficult than ever, perhaps even outright impossible.
Although Fairy Meng Shang and the others wouldn't improve as much as Ling Tian even if they reversed their golden cores again, some among them were sure to break through to Quasi-Saint Rank Seven. At worst, they would reach the peak of Rank Six. At that level, they wouldn't fear Rank Seven cultivators either.
In short, if Ling Tian and Fairy Meng Shang's group
