During a deep-sea rescue mission, the deep-sea rescue submarine "Deep Diver-07" encountered a sudden change in the geology of the seafloor, and all crew members were forced to surface urgently. However, when the submarine rushed out of the sea, there was no rescue ship above the sea. The sky was an abnormally dark purple, and tens of thousands of dead bodies of prehistoric creatures that had long been extinct were floating on the sea.
What's even more terrifying is that the logs disappeared, the personnel lists did not match, unknown foreign objects appeared in the divers' bodies, and the submarine radar could not detect anything, but the sonar heard something "knocking on the door."
Captain Ling Feng discovered that they were trapped in a "ghost trench" that did not exist in time. With each dive, they lost one of their senses—first hearing, then vision, then touch. The lights inside the submarine began to flicker with strange frequencies, cold water seeped out of the bulkhead, and the mysterious object without a number was slowly squeezing into their physical space.
This is not a ghost story, this is a physical obliteration from the deepest reaches of the ocean.
