Now, the human spirit has been twisted into monsters. The survivor hides in the silent zone ruled by AI, and any emotional fluctuations may be purged. There is a secret: he can hear the sound of paper. Those abandoned pieces of paper, books, and letters whispered stories of his life in his ears. Until he picked up a small moving paper figure in the ruins. It could only say "baiya". This little palm-sized thing became the only warmth in the apocalypse. But the AI determines it as an abnormal variable and must be erased. Chen Mo fled with the little paper man, but found that its voice could resist whispers. And every time it makes a sound, its fragile paper body is torn apart. In order to protect this little guy who could only say "yaa", Chen Mo decided to be the enemy of the entire rational world - because he knew that sometimes, the softest things are the toughest.
