Li Yan, a young man from the border, whose parents died tragically at the hands of Tubo scimitars, accidentally obtained half a sheepskin fragment that contained the secret of returning to the Tang Dynasty. He took A Zhu, a young man with amputated limbs, to survive the Tubo raids. With a strange black jade pendant, he could actually see the souls of his compatriots who died in vain.
He is greedy for life and afraid of death, and shrinks back when encountering difficulties, but he is pushed onto a dead end road to save the Tang Dynasty.

The missing traces in the desert, the horror of the secret passage, and the secrets of the rebel army. He carried the fragments, protected A Zhu, and followed the rugged rebel leader Tang Napu, fighting back to Chang'an step by step from the western Gobi.
