Me Behind the Wall

"I can't forget anything." This is Ge Ming's biggest curse. Hyperamnesia allows him to remember every second of his life - down to the number of beats of his left eyelid, and the brand of slippers worn by the residents upstairs when they moved out. At two in the morning, two officers knocked on his door. They showed him a picture: a wasteland, a huge circular depression. "Everyone has forgotten this place." Said the female officer, "including yourself." Ge Ming closed his eyes. The memory came flooding back - he had actually been there, wearing a military uniform and holding a glowing device in his hand. But he never joined the military. What's even weirder is that the memory is in the third person. It's like watching someone else's video. As his memories deepened, he discovered that there were seven locks sealed by his own hands in his brain. Every time one is opened, a personality wakes up. They call themselves "different Ge Weiguo" - his father, the father who made different choices in seven different timelines. The seventh personality tells the truth: the earth will disappear in 2087. Not because of nuclear war, not because of asteroids, but a physical phenomenon that lives in memory. It exists as long as anyone remembers it. And Ge Ming was the last person to remember.
