Takeaway boy Su Mo picked up a silver-gray metal box on a rainy night. Inside the box is a pair of odd-looking glasses. After putting it on, a translucent data stream floated in his field of vision - this was a brain-computer interface prototype from the future, number 36. It can connect to the Internet, scan, pay, and even project navigation arrows on his retinas. Su Mo used it to take orders and deliver food, doubling his efficiency. Until the early morning of the third day, when he was waiting at the red light, a line of small words flashed on the edge of the lens: "Recording: Day 1. Remaining time until the data packet is sent: 71 days, 23 hours and 59 minutes."
