Age of Echoes: Protocol of the Silent

I woke up in the isolation room, number 07. They say that I am the "Silent One" and the only one who can hear the "ringing" in the last days. But I know that what I hear is not only the ringing of the bell - but also the heartbeat of the underground, the pulse of the deep space, and the breathing of another myself. The identity tag brought back from the red wasteland was engraved with the same name as mine: Chen Mingyuan. PLA-2044-11703. The photo on the card is of me four years ago. If I am Sample 07, then who is ST-7 kneeling on the ground? If I were Chen Mingyuan, what was Dr. Li Wei, who was counting my heartbeats, hiding? When the signal from the Kunlun Station penetrated the rock formations, and when the nodes in the depths of the Pacific Ocean began to "breathe," I finally understood: This is not survival in the apocalypse, but an "examination" that spans time and space. Humans, on the other hand, are just candidates who have just received their exam papers.
