City ​​Proofreader

In a world where reality is built with words, a typo is a disaster. The last subway train in Linjiang City entered the bottom of the river, not because of a malfunction, but because the "running" on the line sign changed to "stopped". Xu Zhou, an intern editor, accidentally got a red pen. He can see and correct "typos" in reality, so as to rewrite the tragedy that is about to happen. But proofreading came at a price: every time he changed a word, he permanently lost a piece of his memory. From deleted passengers to disappeared streets, from abandoned draft areas to high-dimensional review schools. When the entire city turns into a useless manuscript waiting to be destroyed, how should the only proofreader put his pen to paper?
