Su Yan, an intangible cultural heritage restorer, just wants to repair wood quietly and live a small life.
Until one day, she opened the mortise and tenon wooden box left by her grandfather——
"Welcome to the rules space."
"Rule No. 1: Don't touch the black lines."
She was just about to complain: Who wrote this second grade reminder?
The next second, he was drawn into a maze of mortise and tenon that could eat people.
It turns out that there is a kind of "space with strange rules" in the world, and each space is bound to an endangered intangible cultural heritage skill.
Want to live? Follow the rules.
Want to die? Feel free to step on thunder.
And the only people who can break the rules are those who master these skills.
In order to find her missing grandfather, Su Yan joined the mysterious organization-Intangible Cultural Heritage Protection Bureau.
Here, she met the poisonous and powerful ace Lu Jin.
He is responsible for fighting monsters, and she is responsible for solving puzzles. The two are forced to become a "life and death partner."
"Hey, can you stop touching things?"
"... I just wanted to see how it broke."
"What do you mean by looking for clues? What do you mean by dismantling the house?"
From the mortise and tenon labyrinth, to the illusion of shadow play, to the forbidden place of batik...
Every rule is a fatal trap, and every crack relies on intangible cultural heritage skills.
But as the exploration deepened, Su Yan discovered:
Grandpa's disappearance, the emergence of regulated space, capital's coveting of intangible cultural heritage...
There seems to be a huge conspiracy hidden behind it that can subvert the world.
Rules are not shackles, they are protection.
Intangible cultural heritage is not the past, it is the future.
When something strange comes, they must use traditional skills to fight against the unknown.
Keep the roots of human civilization in ghost stories.
