Returning to the Great Dream of Traveling to Mountains and Seas

I went far away to have a feast in the human world, and the mountains and seas were roaring, and I never came back. … My name is Li Guiyun, Gui from the dream, Yun from nowhere in the depths of the clouds, come to keep the appointment, hold the sword in hand, and go to the mountains and seas together! —— PS: Wen's martial arts world view fan, please give it a try.
