Perhaps only Shi Lin and the others believed that Ling Tian's group had nothing to fear from experts nearing the Sage level. Their friends and family might not be so fearless. Everyone knew that Ling Tian cared deeply about his loved ones and would never let his people take such risks. In that case, if members of a major faction approached, Ling Tian's group would likely have a large number of cultivators abandon their temporary bases and flee. They wouldn't be able to inflict many casualties on those factions.
Those major factions each had tens of thousands of ninth-level cultivators. The number killed would be only a tiny fraction of their forces, no more than a drop in the bucket. They wouldn't care and would keep hunting Ling Tian's group—especially the factions that hadn't been intercepted. The many factions could then easily force Ling Tian's group back to the Fengyun Realm and destroy them along with the Myriad Sword Demon Extermination Grand Formation, just as Shi Lin and the others had expected.
