This body of water exceeds a depth of one hundred meters, which is generally the limit for ordinary divers due to ocean pressure. Further deepening by over ten or twenty meters could potentially cause decompression sickness, and in more severe cases, the blood vessels throughout the body might burst.
However, for Huo Sining, these issues are non-existent. Even if she were to dive into trenches two or three hundred meters deep, she could handle it. Yet, the underwater environment is mysterious and unpredictable, with too many unknowns, making her hesitant to venture alone.
It was nighttime, and the sea bottom was complex and changeable. The water was murky and dark, with low visibility, and there were many reefs and hard rock hills. Divers dared not move freely after diving but could only rely on overhead searchlights to slowly descend and cautiously advance.
