The story of "World of Misty Rain" takes place in an overhead ancient world. In the depths of the Kunlun Snow Mountain, there are legends about the Temple of War: it contains everything that can make the world crazy—sword soldiers, cheats, wealth and immortality. For hundreds of years, everyone who embarked on a treasure hunt has been buried in endless snow. It was not until decades ago that the Jianghu decent teamed up to form the Yitian League and successfully defeated the demon. Afterwards, a mysterious "White Tiger Jade Ju" was reproduced in a river and lake accompanied by a secret that had been kept for many years... Our game protagonist embarked on his own journey under this background.
