A broken jade pendant with the flying sky pattern of Xixia connects three time and space: in 1941, Zhou Chengyuan took the jade to search for his father and uncovered the secret history of his father's "Guardian"; in 1998, laid-off female worker Zhou Xiaomei used the jade to pursue and decipher the truth about the family guardian; in 2023, programmer Lin Xiaoman used AI decoding to let digital light and shadow communicate with the Millennium Scripture. From the war in the Republic of China to the digital age, three generations used jade pendants as keys to write stories about ordinary people and the land of Hexi among the gravels of Hexi. "Above the sand sea, under the starlight, the guardian's soul will return to eternity forever."
