In 1923, Li Jinyan, a librarian in Peking, accidentally tore up ancient books and activated the incomplete "divine sign" system, which could summon projections of historical figures - but they were all defective products lacking memories and arms. It was a time of chaos in Beiyang, with purple seams cracking in the sky, fairy mountains hanging upside down, and warlords beginning to snatch spiritual energy resources. Facing Guan Gong, who only had his upper body left, and Zhuge Liang, who believed that cars were monsters, Li Jinyan just wanted to survive, but was forced to deal with various forces. And he gradually discovered that this world was actually the experimental ground of advanced civilization, and his own bloodline contained choices that could subvert both worlds.
