What is even stranger is that only a pair of funerary objects were missing from the numerous national cultural relics in the tomb. Why did grave robbers die in ancient tombs? What is the purpose of taking away the funerary objects?

Who is the old man? Why are all the dead people stripped of their bones by strange methods? Can Zhang Yicheng uncover the truth with his father?
