Quantum Tunneling

A person who checks someone else's identity finds out at the end that he has no identity. In a perfect world, the only imperfect thing is yourself. Los Angeles. Quantum state era. Your consciousness can be quantized away from the body and go anywhere in the most perfect image. There is no distance, no discrimination, no disease, no aging. The system will adjust the temperature, light, and mood for you, allowing you to live in a "just right" state. This is a utopia - no war, no hunger, no suffering. But some people start to forget what they look like. Lu Yuan is a quantum identity investigator. His job is to check for "signature anomalies" - people living with an identity that is not their own. He thought he was checking someone else. At the end of the investigation, he found that all the clues pointed to a gray building with no house number in the old city. Behind the door sat a man with his own face. The man said, "I just want you to remember." Lu Yuan spent an entire book trying to find out who the other person was. In the end, he discovered that what he was looking for was how he lost it. This is not a book about "system confrontation." It's not even a book about "whether utopia is good or not." It was just a person sitting in an empty room, looking at the half-eaten bread on the table - and then he remembered: the holes in the bread are small, the burnt edges are curved, and the core is soft. These are all true. And this is enough.
