In the Huachen Federation in 2147, if you say a wrong word, your memory will be erased, and writing down a Chinese character is a death penalty. Shen Yan, a ninth-class citizen, could only survive with 100 simple code words every day, until he picked up half a Spring Festival couplet with the word "" written in the garbage. The moment you touch it, memories that have been buried for hundreds of years come flooding back - it turns out that the words are alive, but the people have long been speechless. He joined the underground "word keepers" and secretly wrote the first "I" behind the iron curtain of the algorithm with his nails, blood and silence. This is not a violent revolution, but a silent echo: when the world prohibits naming, those who dare to write are the last fire.
