Chinese cultural relics were plundered, lost in wars, and scattered throughout history. Overseas, they survived by disguising themselves as humans. Over the long years, their pain and isolation gradually made them lose their memories and sense of self as cultural relics. The protagonist, Chang Xin, leads Yue Jian, Qin Yong, and Zeng Zhong in a four-person team searching for their lost relics. With clues from Dr. Su, an ordinary historian, they set out to find the missing cultural treasures.
