When Lin Wan'er, along with Zhou Jiasheng who had come to deliver a message, found Zhou Chun and his group, they had just followed Taoist Mingjing in capturing the second stronghold for less than half a day.
On the day they split into four groups, they quickly captured the first stronghold guarded by only one Protector of the Dragon Transformation Sect, then after a short rest, they attacked this second stronghold.
This second stronghold, however, had as many as three Purple Mansion Phase Cultivators and sixteen Foundation Establishment Stage Cultivators stationed, and it took them a day and a half to break the protective array.
In the end, they still allowed one of the three Purple Mansion Phase Cultivators to escape, failing to completely annihilate the enemy.
