简介：Qingfeng Valley is not like other forces where hemispherical defensive walls dominate! Instead, the world-famous Superior Immortal Forbidden City 'Yin and Yang Two Heavens' is uniquely set up on the top of the valley. Two superior Immortal Forbidden Formation walls are superimposed high in the sky, with the man-made peaks in the valley as the center of the formation! One layer of black and one layer of white, imitating the day and night of the outside world! It's completely in a league of its own.
