Something below the Sea Hard version

A team of scientists discovered a massive stretch of ocean choked with garbage, a growing danger to marine life and the balance of the ecosystem. Determined to act, they designed advanced drones to sweep away the waste and restore the sea. As the machines began their mission, however, they uncovered something far more unsettling beneath the debris—something hidden from the world for years. What started as an environmental rescue soon turned into a mystery that could change everything they thought they knew about the planet and the dark secret buried beneath its polluted waters.
