Li Ming, the core technical backbone who was ruthlessly laid off by "Qihang Technology", put on a helmet to make a living and became a delivery boy traveling through the city streets. The fingertips that once tapped codes are now holding on to the handlebars to deliver meals. The old technical dreams were dusted while running around, until a strange order broke the calm - he received an "unmanned order" sent to an abandoned office building. The recipient information was blank, but the food was old-fashioned pastries that had been discontinued. The pickup address actually coincided with the floor where he worked overtime when he first joined the company five years ago.
What's even more bizarre is that every night since then, he will always receive orders from the same anonymous number. The delivery address connects the key nodes of the "Sky Dome" project: the server room where the core code was once stored, the old site of Wang Lei's office, and the downstairs of Zhang Tao's current residence. There are fragmented numbers and symbols hidden in the order notes, which are very similar to the encryption algorithm he wrote back then. During the food delivery, there are always people following him in the dark, but he is the only figure in the surveillance video.
When he tried to decipher the truth of these strange orders, he found that he was step by step involved in a huge conspiracy surrounding the "Sky Dome" project - his dismissal was no accident. The bugs in the project after Zhang Tao took over were caused by human manipulation, and those anonymous orders may be someone using his technical ability to find key evidence that was covered up. The former technical backbone, now as a deliveryman, plays a suspenseful game about the truth and survival in the city's surveillance blind spots and time gaps, and every meal he delivers may be the key to unlocking the conspiracy.
