The rest of Xuanwu's story goes that, as he continued his cultivation on Bai Ma Shan, his body gained so much weight that the mountain could no longer support it - and crashed down. The falling rocks from the mountain formed Luan Shi Jiao (Chaos Stone Cellar), while the cracked and crooked 'saddle' of the mountain remains. At this point, Xuanwu moved to Jin Ding (Golden Summit); a higher mountain in Wu Dang. It was at Jin Ding that he eventually attained immortality.
