At the end of the Tang Dynasty, Tongguan fell. Chen Wu, a soldier of the Shence Army, woke up from the pile of corpses and forgot everything except his name. He only remembered the sound of an iron staff falling to the ground in his dream.
Over the next hundred years, nine dead people were resurrected one after another. They were insignificant people like defeated soldiers and scribes, but they experienced Huang Chao's entry into the capital, Zhu Wen's replacement of the Tang Dynasty, Liang and Jin's struggle for hegemony, Yanyun's cession, the change of the Five Dynasties, the Chenqiao Mutiny and the Chanyuan Alliance.
