Infinite Forgetfulness

Li Yuepeng woke up in the garbage mountain on Gray Reef Star and lost all his memory. He soon discovered a strange thing: people who had spoken to him would forget about him when they turned around; the origins of things he had touched would soon be lost; even the surveillance camera could not capture his face. He thought it was a minor problem that no one cared about, until that day, he saw the powerful people on the entire planet frantically looking for a "non-existent person".
