Chi Xue and the others had rebuilt two sect headquarters, and they still needed to leave some people behind at their previous headquarters. That meant they couldn't station all their forces at a single rebuilt headquarters, giving Ling Tian and his companions an opportunity. They could bring everyone into the Small World, conceal their auras, change their appearances, and sneak up on their target. Then they could release everyone and launch a thunderous surprise attack.
As mentioned before, Chi Xue and the others had spread out their forces, so it would take time to gather their troops. Even the cultivators stationed at the rebuilt headquarters would need time to reach the outer protective formation and take up positions. That would be more than enough for Ling Tian and his companions to destroy the formation, since the protective formations around Chi Xue and the others' rebuilt bases were only of average strength.
Of course, Ling Tian and his companions could only destroy the outer protective formation. They couldn't threaten the headquarters behind it, because numerous Satellite Flying Saucers guarded the formation, and many super main cannons were stationed there as well. Even Ling Tian and his companions would suffer heavy losses if they charged toward the headquarters under fire from all those weapons, and that was the last thing they wanted.
In other words, unless they destroyed the Satellite Flying Saucers, they couldn't threaten the headquarters behind the protective formation. But destroying the Satellite Flying Saucers and super main cannons would take a long time—and that would be plenty of time for Chi Xue and the others' forces to arrive. Once they did, Ling Tian and his companions would have no choice but to retreat.
Still, destroying the rebuilt headquarters wasn't their goal. They only wanted to destroy as many Satellite
