Buried beneath China's Ancient Caves lies a secret older than humanity... and it just woke up.

AI expert Luke Taylor thinks he's joining a routine expedition into the caverns of Xianyang. Alongside a billionaire thrill-seeker, a corporate survivalist, a snarky influencer, and a retired soldier, he expects rough terrain -- not revelations that could rewrite Earth's history.

As they descend into a vast subterranean world, what begins as a high-tech cave tour spirals into a desperate struggle for survival. Ancient ruins fused with impossible technologies hint at a lost intelligence -- one not entirely extinct. Their guide warns of the "Echoing Halls," a place where sound moves through time and stone remembers.

When seismic tremors grow more frequent and the walls themselves begin to pulse with unnatural energy, Luke realizes they haven't just found something. They've activated it.

Beneath is a gripping sci-fi thriller packed with pulse-pounding action, layered mystery, and a creeping sense of awe and dread.
