After midnight, there will be an extra layer of non-existent world in the city.
There are subways that will never stop, house numbers that will replace residents, floors that appear out of thin air, and foreign objects born from human oblivion.
Ordinary people can't see it and won't remember it.
Until Gu Linchuan, an eighteen-year-old delivery boy, pushed open a door with 4044 written on it while delivering an order at midnight.

Rules can be modified.
The space can be modified.
Death can be modified.

Later, his name could not be found in the files.
Later, all traces of him disappeared little by little...
When Gu Linchuan pursued the truth, he discovered that the world in which humans live is just a huge curtain that covers the reality.
But what really needs to be modified is never the rules.
But the whole world.
