Under the South China Sea, there is an invisible university.
Students here can hear the cultural relics speak, can make history repeat themselves, and can make the words in ancient books come alive.
Some of the teachers here have lived for thousands of years, and some are not human at all.
Their job is to protect "history from being tampered with."
——Until four new students who were covered in injuries entered the school.
A man who was sold to the organization by his parents as a guinea pig. He has white hair, social fear, and a taboo power that can destroy the memory of civilization.
A person who has been treated as a slave since childhood, but wants to be some kind of "guardian", following others around to clean up messes all day long.
A sixteen-year-old loses everything and uses "forgetfulness" to protect himself. Every time he uses his ability, he has to exchange his memory for it.
A woman who lost her parents at a young age uses her smile as armor and the sea of data as her only weapon.
They are the people chosen by history, and they are also the people abandoned by history.
Carrying the covenant made a thousand years ago, I must protect this school under the sea before completely going crazy.
And the people who live in the school - those "weapon spirits" who have awakened from the depths of civilization.
And, each other.
Concept: History is the long river of time, and cultural relics are like streams, bringing new life to the sea of civilization. Human beings create history, history creates civilization, and civilization creates human beings.
