As the master of the Sword-Forging Sect, one of the three great powers, Duan Chenxing possesses extraordinary strength. Alongside Duan Jiu, a modified human, he presses forward, carrying the unfulfilled wish of Duan Yi, whom he never took on as a disciple. Danger lies ahead at every turn. How will they face it? Who can grasp a sword and command the mountains and rivers? Life is short: for whom do we live, and for whom do we die? The wild goose flies over the mud, leaving no trace; how many autumns have passed as I toss and turn by the window? When we meet again, our heads will be covered in snow, yet your beauty will still shine in those clear eyes.
