During the Northern and Southern Dynasties, the powerful Northern Wei marched south, launching a massive invasion by lamas and stirring up the martial world of the Central Plains. Their martial skills were formidable, and soon the Central Plains martial world stood on the brink of collapse. The Persian Zoroastrian sect was especially powerful. They occupied Mount Shaoshi, Mount Shaohua, and other places, working with the Northern Wei court to destroy Central Plains culture and kill those who resisted. They sought to bring all the Central Plains under the rule of their barbarian people, slaughtering Han women at will and forcing the Central Plains court and prominent Han clans to migrate south again and again. This brings to the fore Yan Qinghui, the first beauty of Jiangnan and an immortal maiden of the Penglai Sect; Qiang Muyun of the Wushan Hundred Herbs Sect; Chen Lijun of the Chaoyin Pavilion; Ximen Wuyan of the Swordplay Society in Wuyi Alley; the Six-Fingered Daoist of Mount Luofu; the greatest swordsman of the Central Plains; and many other prestigious sects. Xiao Zhuyin, once a frail scholar, is forced into the dangers of the martial world. From a weakling, he gradually hones himself into a pillar of the Central Plains martial world. The many tribulations of love, the many affections of his beloved, the ruthlessness of the red-robed lamas, and the treachery of the martial world all put him to the test.
