Hollow Echo

——When the universe starts to tamper with memories, can you still believe in your own existence? In 2187, humans conquered the solar system, but were trapped in the cage of time. During a deep space salvage mission, former quantum physicist Cheng Ye received an impossible signal - from the colonial ship "Ark" that disappeared in 2147. What's even weirder is that the signal contains future technological information from 2173. When he set foot on the ice of Europa and drilled into the darkness three thousand meters below, what awaited him was a wreckage that was exactly the same as his spaceship. The serial number on the ship had long been erased, leaving only a line of words engraved on the metal wall: "Welcome back, Dr. Cheng Ye." At the same time, his mechanical prosthesis began to operate autonomously and decoded memories that did not belong to him; his partner Lena Voss had a fifth injection mark inexplicably on her neck - although she insisted that she only received four injections; a warning from the future emerged in the core code of AI Noah: "Don't answer. They're changing history." As the investigation deepened, Cheng Ye discovered that twelve giant structures were emerging at the edge of the solar system. They were arranged in precise geometric patterns, like some kind of cosmic-level instrument. And the "Echo Network" that the deep space fleet is about to launch may be the key to opening the door to disaster... ◆Time is collapsing and reality is constantly being covered ◆How many of your memories are true? ◆What did humans see on September 14, 2173?
