Zhang Family sent a considerable number of cultivators whose strength far surpassed the Li Clan, yet the problem lies in their attacking the Li Clan grounds!
This is the most solidly defended place of the Li Clan.
It's not that the Zhang Family couldn't take down Mount Wanxian, but with the strength of just this group of cultivators, breaking through the Li Clan's defenses would undoubtedly come at a great cost!
Keep in mind, the Li Clan's Mountain Protection Array is not a mere Sixth Rank Formation, but a Seventh Rank!
Moreover, the person who set up the Formation, Jiang Fengwu, has returned to the clan and personally presides over it, ensuring the Formation can unleash its full power.
The Zhang Family couldn't possibly be unaware of the grade of the Li Clan's Guardian Mountain, yet they still only sent these cultivators. Besides having to guard against the three major forces of Qingzhu Sect, their main reason was underestimating the Li Clan.
