The Long Night I: the Unknown Book

The world is not created, but modified over and over again. On the first day after entering Yuandian College, Gu Linshu discovered something strange: there were only seven freshmen on the train list, but an eighth person was sitting in the carriage. The girl Mia has no identity, no origin, and is not remembered by anyone. What's even more frightening is that the seats, tableware, rooms and even memories related to her are disappearing one after another. When Gu Linshu tried to prove her existence, the academy judged him as a "person without origin" and began to delete his name. On the verge of disappearing, he unexpectedly gained the ability to see "deletion marks" in the world - those deleted people and things did not completely disappear, but left traces on the back of reality. He can even temporarily borrow the abilities from the remnant. The price is that every time he borrows it, he will lose a piece of his own memory. In order to keep his name and find his sister who has been missing for many years, Gu Linshu must find out the person who deleted the manuscript hidden in the college before he forgets himself. However, when the clues pointed to the "Unknown Book" that never existed, he discovered: Perhaps more than one person has been deleted. But the first page of the whole world.
