In order to find writing materials, the down-and-out writer visited an antique shop owner named Wu Xie (played by Lu Han), who was about to leave the city. Before leaving, Wu Xie told him about his strange family history of tomb robbers and the strange events he experienced during his first family adventure: that time, their family accidentally obtained a special bronze ware, and traced the source and found the ancient country of Queen Mother of the West buried in the northwest basin of China. They recruited a group of tomb robbers to explore the ruins of the ancient city together, entered the Queen Mother of the West's tomb located underground in the ancient city, and discovered the truth that King Mu of Zhou asked Queen Mother of the West for the art of immortality. After listening to Wu Xie's story, the writer found many doubts in it. Was Wu Xie talking about his own imagination, or was the truth more terrifying and complicated, because Wu Xie's departure became an eternal mystery.
