On November 11, 1918, the First World War ended. Su Cheng woke up in an attic in Shanghai, with the next hundred years of world history in his mind.
He knew that Versailles and the date planted the seeds of World War II, knew the battle plan for the September 18th Incident, and knew the course of the fleet at Pearl Harbor - but he couldn't say. To speak out is to die.
He can only do one thing: stuff intelligence into the gears of history, and make the gears turn one degree at every critical node.
From Shanghai to the Paris Peace Conference, from the Kwantung Army Intelligence Section to Tokyo's underground radio station, he traveled among the intelligence agencies of six countries. The Japanese were looking for him, the British were looking for him, and the Soviets also wanted to find him.
But no one knows who he is.
He knows too much. And he is using this knowledge to rewrite a world war. !
