The rivers and lakes are in dispute, the Frost God Sword reappears in the rivers and lakes, there are many sects, and the Beiyuan Dynasty guards the Central Plains. There are thousands of snow-capped mountains to the north, which hide ancient martial arts. It is said that a hundred years ago, someone broke through the void and climbed the ladder to heaven to become an immortal. The world is divided into five kingdoms: the Yanzhou Fire Sect governs thirty-six caves in the south, the desert Jinlun Temple governs various tribes in the west, the sea country Penglai in the east, floating islands in the sky, and the Youshuang Realm in the north, where ghost cultivators loom in the ice fields. Martial arts are prosperous, ordinary people can use external strength, and masters can open mountains and cut off rivers at the ninth level. In the Jue Valley of Shu, the Tang Sect is good at trap poison. In order to seize the Frost Divine Sword, the five elders of the Tang Sect hid the truth from the old master Tang Aoning and wiped out Qingxi Village with blood. Only a young boy named Su Wen, nicknamed A Nuo, was rescued by Wu Yanfeng, Si Tianjian's national master. There are no immortal traces in this world, but there are legends of ascension to the sky everywhere. The Weapons Manual, the List of Secrets of Heaven, and the Footnotes of Journey to Nine Provinces are known as the three great books, attracting countless heroes to compete with each other. Warriors do not worship gods and Buddhas, but only respect the sword bones of sages. The mountains and rivers are vast, and when the winter plum blossoms bloom, there are always people crossing the bridge with swords in their hands and snow on their skirts.
