The Mountain Protection Array of Luofeng Mountain reaches Tier Four Top Grade, slightly surpassing the Mountain Protection Array on the Chen Family's White Camel Peak.
Normally, even if the Yellow Sand Sect held an absolute advantage in numbers, breaking this array in a short time would be extremely difficult.
However, since Luofeng Mountain originally belonged to the Yellow Sand Sect, the information about the Mountain Protection Array here is recorded within the Sect, accessible only to the Sect Leader as classified materials.
Zhang Yunpeng unlocked the information on the Mountain Protection Array at Luofeng Mountain seven or eight years ago and handed it over to several array masters within the Sect for research and to find the array's weaknesses.
And Jiang Yuyan has repeatedly attacked the array over the years to test and confirm whether the research by the sect's array masters is reliable.
