Tang Xiaoyu and his friends came to Lop Nur with the scientific expedition team and stayed at the 'Desert Hotel'.
But isn't this 'Desert Hotel' too strange? Tang Xiaoyu ignored the ban and opened the door in the middle of the night and saw a horrific scene.
Leave? But the entire scientific expedition team disappeared!
Tang Xiaoyu received a call from his father.
"The forbidden land of death... The treasure of the patron saint..."
Xia Zizhe's luck played a role... The mysterious totem in the secret passage seemed familiar...
At the exit of the secret passage, Tang Xiaoyu and his party were all discovered. Was there an ambush or was it just their luck?
In the dark room and the familiar boy, Tang Xiaoyu had a headache.
Escape, Shiyue tells Tang Xiaoyu the truth.
Is the legend of the patron saint's treasure real?
... Perhaps, everything has already been decided...
