The Rules Become Chains, and the Ego Wields Two Swords to Chop and Chop.

I don't know where I got it from. I don't know what that world was like. I don't know who I was in the original world. These memories are all gone, clean, with "White Light" written on the cover. I looked at that thing in the sky - that huge sphere with its left half white and the right half black, its surface covered with chains, hanging in the air and covering half of the sky - I had only one judgment in my mind: this kind of thing does not belong to any world within the scope of my knowledge. I've traveled through time. A man wearing a bamboo hat stood in the distance. The green robe, with its back to me, facing the city. The wind blew from over there, causing the hem of the blue robe to sway slightly. I looked at him. I watched it for a few seconds. Then speak. "Where is this?" He didn't look back. The sound of wind. A distant buzzing sound. "The homework is not finished." "It's not waste." He didn't answer. The giant ball is still there. The chain net is still there. The fog is still there. The shell man is still there. The sound is still there. He looked at the city. I also looked at the city. Two people. One is standing and one is sitting. One knows everything, the other remembers nothing. One is outside the fog, and the other has just woken up from the fog. The setting sun spread out between us, casting two shadows on the rooftop, one long and one short, both pointing in the same direction. I looked at the city covered in black and white fog. A voice came from the front. "My name is Cang Yu."
