Cheng Siping, a laid-back otaku, instinctively gives his life to save a strange little girl and dies a tragic death. But after he dies, he is told that, despite being a nobody in the world of the living and a complete failure, he somehow accumulated immense merit and earned the special respect of the Underworld. He receives glory in death. He thinks that from now on, he can enjoy a secure job and rise to the peak of ghostly life. Unexpectedly, however, Black and White Impermanence scheme against him, and he is reincarnated in another world, becoming a so-called Plane Lord burdened with a System and liable to bite the dust at any moment... Since he's already here, he might as well make the best of it. Cheng Siping had wanted to quietly work as a ghost official, but can only accept reality, all the while imagining that one day he'll achieve greatness and unite the world. Who could have guessed that from the start, he'd be worse off than a dog...
