Five hundred years ago, the Golden-Winged Great Peng, the Blue Lion, and the White Elephant seized Lion Camel Ridge, massacred the people of Lion Camel Kingdom, and established a demon realm. When Tang Sanzang and his disciples traveled westward and reached this place, the three demons plotted to kidnap Tang Sanzang. Sun Wukong launched multiple rescue attempts and engaged in fierce battles with the three demons. He was once swallowed whole by the Blue Lion and trapped in the Yin-Yang Dual-Qi Vase, but escaped using his divine powers and the life-saving hairs given by Guanyin, rescuing Zhu Bajie, Sha Wujing, and the White Dragon Horse. Outmatched, the three demons retreated to Lion Camel City, using Tang Sanzang as bait to lure Sun Wukong into a final showdown.
