Ziyang's headlamp illuminated a fan-shaped area of about 60 degrees ahead.
The candela (light intensity) and lumens of this headlamp were exceptionally high.
It could illuminate hundreds of meters away in the pitch-black sea.
Although there were many impurities in the sea making it impossible to clearly see the shapes of things,
it was still no problem to discern the outline of distant objects.
Besides, Ziyang had a thumb-thick rope tied around his waist, ensuring he could be pulled back onto the fishing boat by the crew quickly if he encountered shark attacks or other dangers.
After entering the water, his body couldn't help but shiver slightly.
The icy cold sea made his skin start to tingle.
Ziyang didn't carry complete diving gear, possessing only a few simple necessary tools.
Thus the heat loss from his body in the water would be very fast.
"Seems I can only stay underwater for about ten minutes at most."
