Hu Bayi assembles a crew of seasoned adventurers to hunt for one of history's most coveted artifacts: the Qin Emperor's Bone Mirror. Their expedition launches from Coral Temple Island in the South China Sea aboard the Trident, guided by the enigmatic captain Ruan Hei and his protégé. What begins as a straightforward treasure hunt fractures when the ship crashes into Guixu, a legendary realm where ancient secrets refuse to stay buried. Inside the shipwreck's depths, the team uncovers far more than a forgotten mirror. They stumble onto a conspiracy that binds Ruan Hei to a mysterious figure from his past, one who may have every reason to see them dead. As night falls on their temporary camp, a hooded stranger emerges from the shadows wielding a weapon, setting off a chain of events that threatens to unravel everything they thought they understood. This is adventure laced with paranoia and supernatural dread. Betrayal lurks in plain sight, and every companion might conceal a secret agenda.
