The Long Night I: the Unknown Book

Yuandian College only admitted seven new students. But there is a fourth bed in the dormitory, and there is always a fifth dinner plate in the cafeteria. Everyone also remembers that they once had a "fourth friend." Only no one remembers who she is. Until Gu Linshu saw the name of the girl Mia in the missing roster - and her graduation date twenty years later. In order to prove the existence of a person denied by the world, Gu Linshu and his companions began to trace the traces of life she left behind. But as the investigation deepens, non-existent courses start quietly, the missing professor leaves a warning, and the sleeping ancient city beneath the college gradually wakes up. And the book dedicated to recording "unknown people" was silently turning to the last page: **The first page has been stolen. ** When history can be modified and names can be deleted, who can prove that you have been in this world?
