Lu Chen, a cultural relic restorer who was burdened with a huge debt of three million, accidentally broke into the mysterious Tomb No. 8 Of King Qin. After touching an ancient bronze mirror, he traveled through the Qin Dynasty and possessed Chen Xu, a dying Qin soldier. Living in the harsh military camp of the Qin Army, he not only had to deal with the secret surveillance of Zhao Gao's forces, but also relied on modern knowledge and cultural relic restoration skills to survive. In order to find a way home, he offered advice to defeat the Xiongnu and formed an alliance with the mysterious assassin Yue'er. He also tried to change the tragic fate of the young master Fusu, stirring up troubles in the iron-blooded Qin Dynasty, and gradually uncovering the shocking secrets of the ancient bronze mirror and the "historical corridor".
