After the strangeness came, the world had a new iron law. For example, you can't look back at night. For example, there is no answer to the fourth knock on the door. As for Jiang Cheng, he himself is an iron law. In an S-class incident codenamed "Silence", he managed to survive, but he also became the humanoid carrier of the "unspeakable" rule. From then on, the area around him was shrouded in absolute silence, and any active sound would trigger a mortal curse. He is mankind's most powerful weapon and the most dangerous restricted area. He was organized to deal with other tricky weirdness, using one rule to overwrite another. But after going deep into crazy events again and again, Jiang Cheng discovered that the "silence" in his body was growing, and its coverage was getting wider and wider, from ten meters, to a hundred meters, to a city... He didn't know that when the whole world fell into silence, would he still be human?
