Chapter 323
Haruto Saito continued diving deeper into the ocean.
The further he went, the darker it became. Eventually, he could no longer see his own hand in front of him. Even in the clearest waters, sunlight could only penetrate up to two hundred meters below the surface. Beyond that, there was nothing but total darkness.
The pressure increased with every meter he descended.
Haruto felt his lungs being compressed.
It was said that when a human dove deeper than a hundred meters on a single breath, their lungs would shrink to the size of a fist. Conversely, if they ascended too quickly from that depth, their lungs could expand and even burst.
This was due to the immense underwater pressure.
A balloon released at a hundred meters below the surface would rise rapidly, and as it ascended, the decreasing external pressure would cause it to expand until it exploded.
For an ordinary person, rapidly surfacing from just fifteen meters below could result in a fatal lung rupture. If they controlled their exhalation, they might avoid death, but the damage to their lungs would still be severe.
Of course, none of this was a concern for Haruto.
He was no ordinary person—he was a shinobi, and one with enhanced physical endurance from rigorous taijutsu training. His lungs would not rupture, though he still had to endure the increasing pressure.
He soon reached two hundred meters.
