Three years ago, the person closest to me disappeared out of thin air in this city, leaving only a number that was always switched off.
Jiang Chen, a delivery boy, has been looking for him for three years but found nothing.
Until that rainy night, he was involved in a shady matter. When he was about to die, a sign-in system that only came in late at night found him.
Sign in at night and become stronger at night. During the day, he was still the ordinary delivery boy who couldn't even climb six floors until he was out of breath.
The rusty iron box in the secret room of the old building, the mysterious supernatural being with a copper plate hanging from his waist, the thin red thread in the crack of the door - there is a world behind this city that he has never seen before.
Opponents range from street gangsters to local families, city councils, and an invisible alliance above them all.
They can drive those who know the information underground and use them as bargaining chips.
But they didn't expect that the most inconspicuous delivery boy would be the one they couldn't afford to mess with once it got dark.
During the day, I deliver food.
After dark—it's my turn to lift the table.
