A modern history student/enthusiast fell asleep while studying an unnamed ancient scroll, and his consciousness traveled to a key "classic event" node in Chinese history, and he was reborn as a newborn baby. He has the memories of an adult and the foreknowledge of the direction of history, but is trapped in the body of a baby. Under the constraints of being unable to speak or walk, he must use his cries, eyes, and body movements to influence the big people around him, thereby changing or witnessing the direction of history in the butterfly effect.
