Time Underworld

During the deep-sea exploration in the 21st century, Chinese scientists discovered the mysterious "sea within a sea" deep in the ocean - a brine pool with extremely high salinity and full of unknowns. Limited by technology, humans cannot explore in depth and can only set up observation equipment around it to silently record every detail of this secret realm. However, as Japan continues to discharge nuclear wastewater, the tranquility of the sea within the sea has been completely broken. Strange crystals began to appear around it, which were initially identified as salt crystals precipitated from salt brine. Until a sea creature touched the crystal, its body crystallized instantly, and then floated still in the sea above the sea. Time seemed to freeze at this moment. Over the past decade, Chinese scientists have secretly established a deep-sea research base on nearby offshore oil drilling platforms. They were horrified to find that under the continuous erosion of nuclear sewage, crystals were spreading to all directions, and the liquid level of the sea was also rising quietly. The crystalline creature remained suspended, like an eternal mark. When the deep-sea submarine sailed into this mutated sea area again, more strange scenes beyond imagination appeared one after another: lines hidden in the crystal body that resembled biological blood vessels, unknown regular radiation pulses, and even the "dead" crystalline creature showed signs of recovery... The truth of the sea within the sea gradually emerged. It was by no means a simple brine pond, and the discharge of nuclear sewage seemed to be awakening some kind of sleeping existence that could subvert human cognition. Human exploration, faced with the unknown deep sea and self-inflicted disasters, is gradually heading towards unpredictable situations.
