At the end of the takeout order is the hidden world.
Chen Mo, a history student, spends his days researching the Caobang code of the Northern Song Dynasty among old papers and running around delivering food for a living at night. An unusually well-paid midnight order led him to the never-open "Ancient Book Restoration Center" deep in the campus.
The pottery jar of wine delivered on time, the mysterious bookmark in the reference room, the cryptic warning from Su Jianxue, a senior student in the dance department... Under the calm daily life of the university, a corner of a modern urban world maintained by the "three meetings and nine streams" and following ancient rules was revealed to him.
From curiosity to involvement, Chen Mo discovered that the market insight and historical expertise he learned while delivering food had become his only weapon for survival in this hidden world where old and new rules collided. And that ignorant pursuit that started on campus will eventually push him into the center of the whirlpool that stirs up the entire world.
