In the Blue River Region, a thick layer of dark clouds obscured the sky and put the vast land in the shadow. The thick darkness permeated the ground, turning it into a mass of erosive soft mud. This caused the soil to tumble and everything on the ground was swallowed in, replaced by more filthy silt pouring up from the bottom.
Like a pitch-black ocean, the beautiful mountains, rivers, trees, and flowers have disappeared. And in the middle of the black ocean, there was a towering sword-like mountain. Like a lonely boat hit by a storm but remained indomitable. From time to time, a dazzling sword light shot from the mountain, splitting the black ocean, setting off a storm. However, in the endless darkness, the sword light quickly dissipated, and the black waves that besieged the mountain came back.
