At the ceremony to worship the heaven, all the civil and military officials knelt down and pressed their foreheads against the floor tiles. The middle-aged emcee shouted the word "sacrifice to the heaven" in a long voice, and Luo Tian took the first step. Wearing a twelve-pointed crown on his head, his black background and gold-patterned dragon robe fluttered slightly in the wind. At his feet were ninety-nine bluestone steps. He walked up step by step, not fast, but each step was as heavy as nails driven into the stone. Every step he took, a scene from the past appeared in his mind. Thirty years passed from a commoner to an entire troubled world. At this moment, he is the only protagonist in this world.
