Shen Yuan is the most disliked graduate student in the Department of Archeology because he insists that the Classic of Mountains and Seas records not mythology but real geography.
On the day his mentor disappeared, he discovered a living spinner turtle at an archaeological site.
The Spin Turtle called his name.
Then, he saw the world that ordinary people couldn't see: the nine-tailed fox shadow wandering around the campus, the curled-up snake with a human face in the subway station, and the three six-eyed birds entrenched on the roof of the office building.
The handwritten fragments of the Classic of Mountains and Seas left by his mentor came to life and became his "navigation to other worlds".
But every time he uses it, he forgets a memory.
He must find his mentor and find the truth before he forgets everything.
What is recorded on the last page of the Classic of Mountains and Seas?
