Shadow Keeper

On a rainy night in Wujiang City, Shen Mian, a night shift delivery rider, received an order that didn't exist—— No. 147, Linjiang Road, pickup code: **·**. After delivering the order, he found that the whole city had turned upside down: the shadows of all the buildings floated off the ground, like a thin layer of water. The sky was gray, the people were gray, and there was only a glass lamp burning deep in the alley. The man holding the lamp told him three rules to save his life—— **Don't be seen. Don't leave any light. Don't trust the shadow. ** Including your own. Shen Mian's sister disappeared three years ago, and all clues point to the depths of the shadow layer. And if he wants to go in to find her, he has to pay a price: every time he sneaks in, the shadow in reality becomes lighter - until it fades to the end, the whole world will forget him. To make matters more troubling, his shadow has a mind of its own. It can move, it can see, it can pick up things that only it can see. One day, it spoke.
