Seven years after the Great Silence, the Earth is still an electromagnetic desert. Plane wreckage rusts on the runway, cities are engulfed by vines, and humans return to the age of torches and sailing ships.
Shen Yuan, a former deep-sea sonar engineer, now makes a living by scrapping scraps from the ruins on the beach. He has a secret: Just touch an object and you can hear all the sounds it has "heard" in the past 30 days.
By chance, he touched a stone washed up from the Mariana Trench - and there was a recording inside that shouldn't exist. That was deep-sea sonar data from the day the "Great Silence" occurred. The frequency did not belong to any known natural phenomenon or human technology.
There is also a woman's voice in the recording: "Shen Yuan, don't come up. Something is awake down there."
That was the voice of his late mentor Fang Lan. She died seven years ago.
In order to pursue the truth, Shen Yuan embarked on a journey across the ruins. Cults hunted him, warlords exploited him, and even the people he saved betrayed him. And the only thing he could trust were the voices in his ears that came from the past, were long dead, but were still speaking.
When he finally dived into the dark trench, he discovered that the "thing" had been waiting for him. And his golden finger was never a talent, but a signal receiver.
