During the Republic of China, supernatural powers first appeared.
When Liu Lao was looking for a way to control the ghosts, Chen Tianyi chose another path - studying the rules of the ghosts and recording the future.
In an accident, he obtained a supernatural item [Ghost Diary].
It can peek into the future, but every observation requires a price - taking away a part of his life from a certain time in the future.
Chen Tianyi discovered that the evil ghost was not unsolvable.
They just follow fixed rules.
When the rules of different ghosts conflict, collide, or even form a logical closed loop, the ghosts will also fall into a "crash" state where they are unable to act.
So, he tried to find a way to modify the supernatural rules.
However, the rules of ghosts cannot be changed.
In the end, in order to leave a way for the future, Chen Tianyi gave up his identity as a human and let the ghost diary integrate into his body and consciousness.
He lost his human identity, but left behind a supernatural object that spanned a hundred years.
Later, it was called: human skin paper.
He wanted to change the future, but ended up recording the future.
