In the near future fictional world (2077), the "Abyss Echo" deep-sea scientific research station. The station is located on the edge of the Challenger Deep in the Mariana Trench. It was originally built to study crustal movements and unknown biological communities. It has been out of contact with the outside world for 73 days. The high pressure, eternal darkness, and isolation of the deep sea naturally breed despair. However, due to the erosion of unknown forces inside the scientific research station, the physical rules and biological logic are undergoing strange distortions.
