Bi Fang took a deep breath and plunged into the water.
The moment he entered the water, Bi Fang's heart rate dropped from 60-70 beats per minute to 30-40, and his blood vessels contracted in response to the shock.
He could distinctly feel his blood leaving his limbs and flowing towards his heart, lungs, and brain.
This sensation was like being lost in a certain space where the direction of the water's surface was indistinguishable, as if he himself were Armstrong stepping onto the moon.
Without the glow of a flashlight or the companionship of fellow divers, the ocean depths seemed even more pitch-black and silent.
Dark waters surrounded him on all sides, with no knowledge of what unknowns lurked within, as if wrapped in the solitude that comes with being on an alien planet.
This is why most underwater operations are conducted in pairs.
Solitude can drive a person mad.
