Since Yan Wugui had shown the way before, Lu Mingshu knew the location of the Snow Winged Cloud-treading Horse's nest.
From where they had exited the underground tunnel, there was an extremely steep precipice. The nest of the Snow Winged Cloud-treading Horse was right at its apex.
The only problem was that precipice was arduous to climb. Not only did it have lots of thorny vines hanging off it, but there were also lots of ferocious birds resting on it. If one wanted to climb up, they had to be careful of both the thorny vines as well as the ferocious birds.
