Unlucky since childhood, Jiang Yao is scraping by in the big city, until life collapses all at once: he’s laid off, his rented room mysteriously burns down, and after paying the damages with his life savings, he’s left penniless.
With nowhere else to go, he returns to the ramshackle, dangerous house his grandfather left behind.

While cleaning, he’s driven off by the house’s guardian: a female ghost named Shen You.
In a frantic dash to escape, Jiang Yao opens the bedroom wardrobe, only to be pulled, along with the pursuing ghost, into the strange world hidden behind it.

Thus begins his wild, episodic “infinite-flow” adventure: one portal after another, one deadly trial after the next.
