Under the calm surface of the ordinary world, an undercurrent is quietly surging.
Li Ming, a young archivist buried in old papers, leads a calm life. Until one day, he suffered a strange "echo" without warning. It was an indescribable experience, as if a sandstorm hundreds of millions of years ago had forcefully poured into his mind the broken images, unfamiliar language symbols, and dizzyingly complex structural diagrams. What followed was that he was able to understand an ancient hieroglyphics that had long since disappeared without any obstacles, and in a trance, he drew precise mechanical drawings that surpassed the understanding of the times.
He's not the only one experiencing "reverberations." All over the world, different people have begun to awaken to their own "echoes": some have mastered the legendary lost building craftsmanship, some can sing ancient songs they have never heard before, some have sensed energy fluctuations that ordinary people cannot detect, and some have even mastered knowledge about the unknown laws of the universe.
