Ma Shi, a delivery rider, has been delivering meals for two years. Late one night, he saw a line of words floating in the air in the corridor: "No running in the corridor after twenty-three o'clock." A man who was running at night rushed in after midnight and never came out. The next day the news said contact was lost, and a week later the news was gone, and even the search records were gone. Only Ma Shi remembers.
There are these words hidden throughout the city, white, yellow and red, with red being the most deadly - those who violate it will not be killed, but will be erased from reality. People who can see these words are called "seeers", one in 100,000. Ma Shi is one of them. Then he looked up at the sky. There was a line of blood-red words across the sky: "Those who see must not exist."
His very existence is the biggest violation.
