Whispers from the Deep: Investigating the History of the Forbidden Era

Lu Shen, formerly a geological researcher at China's State Oceanic Administration, awakened the power of Echoes of the Old Ones after a deep-sea accident: by touching objects connected to the abyss, he could revisit fragments of their history. Recruited as a special investigator by the Abyss Council and the International Marine Anomaly Investigation Bureau (IMO-A), he must piece together the truth behind three civilizational collapses before mental corruption devours his sanity. What was the Primordial Spirit Sea? Why did every civilization fall after hearing the whispers? And who is the entity that taps out three short knocks and one long one in his dreams, waiting for someone to open the door?
