Chen Yu, a student from the Department of Geology, accidentally traveled to the Western Zhou Dynasty and discovered that he had immortality and the power of lightness. From slave to general, he experienced thousands of reincarnations and witnessed the decline of the Zhou royal family, the disputes of the Warring States period and the rise of the Qin Dynasty. He married wives and took concubines, formed the Shadowless Guards, and built a government city, but he watched his lover grow old one by one under the curse of immortality. When he met Ying Zheng, the cruel and suspicious King of Qin, the wheels of history began to shift. In order to end the troubled times, Chen Yu had to raise the flag of rebellion, rose from general to emperor, and finally revealed the mystery of his own immortality - he was actually the "space-time observer" chosen by an alien civilization. This is an epic that spans thousands of years, blending history, fantasy and intrigue, telling the story of the struggle, rise and redemption of the undead in the long river of time.
