Since childhood, the unlucky Jiang Yao had been struggling alone in the big city. After just being laid off from his company job, his rented apartment mysteriously caught fire. Forced to use all his savings to compensate for the damages, he was left penniless once again. With no money to rent a place, Jiang Yao moved back into his outdated and dilapidated house left behind by his late grandfather. While tidying up the old place, he was startled by Shen You — a female ghost guarding the house — who tried to scare him away. In his panic, he accidentally opened the wardrobe in the bedroom, only to be sucked into the world behind it along with Shen You, the ghost “chasing” him. And so began his endless adventure into the infinite realms.
