"How exactly should we escape?"
When Fang Xing asked this question, his mind was truly foggy. Half of it was due to Wu Sang'er, and half because he couldn't figure it out. Back when he kidnapped the black-robed Buddhist Child Hui Neng from the Other Shore Temple at Annihilation Valley, he set up an ambush with a fake treasure reveal. He had observed the valley then, with only one entrance and no exit. Furthermore, the Pure Land cultivators reacted quickly and there were many of them. When they entered the valley, they had already surrounded it completely.
If there is no way to leave, it's as if being trapped, just a slight relief.
Moreover, the defending side is not the same as being outside. Even if the Fengshan Cauldron's power is strong and Wu Sang'er's array skills are superior, if they don't find a way to escape, the Pure Land can eventually figure out how to break the grand formation. At that time, they would be even more dangerous.
