Li Wei, a modern historian, discovers an ancient edition of The Back-Reading Diagram that differs from the commonly circulated version. The image in its first section is not Pangu, but an incomprehensible geometric structure. Li Wei seeks help from Yuan Cong, a mysterious professor of Chinese studies, to interpret the second section. It seems to foretell the founding of the Tang Dynasty...
As they work through their interpretations, they accidentally see what they were never meant to see, and enter a realm they were never meant to enter!
The truth behind The Back-Reading Diagram gradually comes to light...
