Although Chi Xue and the others abandoning their mission meant they no longer had to worry about the Myriad Sword Demon Extermination Grand Formation being destroyed—at least not for a long time—Ling Tian didn't want them to give up so soon. It wasn't just because such intense fighting could rapidly increase his strength while letting him absorb an immense amount of Outer Realm Power. More importantly, he could kill many cultivators from Chi Xue's two factions and make them fall apart.
Once Chi Xue's alliance fell apart, its strength would naturally be greatly diminished, and re-forming the alliance would be almost impossible. That meant they would pose little threat to Ling Tian and the others. If Chi Xue's two alliances disintegrated, they might not get another chance to join forces with Venerable Sword Saint. Ling Tian and the others were confident they could deal with Venerable Sword Saint alone.
It made sense. Although Chi Xue and the others had abandoned this operation, their two factions hadn't fallen apart. They had even retained ninety percent of their strength, which meant they still had a chance to join forces with Venerable Sword Saint in the future. That remained a serious threat to Ling Tian and the others. Once Venerable Sword Saint fused with more golden cores, he could resume attacking them, and if he joined forces with Chi Xue's people, they would have a much better chance of destroying the Myriad Sword Demon Extermination Grand Formation.
In other words, if Ling Tian could make Chi Xue's two factions fall apart, he could resolve the threat for good. But the threat remained, and that was why he felt such regret.
Poqiong understood Ling Tian better than anyone and knew what he regretted. Still, he thought of something to console him: what was done
