After four years of delivering food, Chen Li never picks an order. Until that night, the system sent him an order - No. 37 Huaishu Lane, two bowls of wontons, with extra coriander. The note read: Knock gently, the child is asleep.
But Huaishu Lane was demolished nine years ago.
He pressed the navigation button, rode into a non-existent alley, and bumped into a wonton stall that was open. The boss lady said: After eating this bowl of wontons, you will forget the things you want to remember most. He didn't eat. Because what he wants to remember most is a little girl who disappeared under the streetlight nine years ago - his sister.
An old man who had been keeping the lamp for nine years put half a lamp into his hand: the lamp recognizes people. If there is something you want to protect in your heart, it will shine.
From then on, Chen Li had an extra pair of eyes: he could see the rules under the street lights, the strange stories told by the lights-out department, and the organization hidden behind the city - the long night.
But the price of this road is: every time the light turns on, a piece of his memory is burned away.
He is looking for his sister and forgetting her day by day.
Before he burns himself into a stranger, he must find out why the street lights went out one after another on that rainy night nine years ago.
