When the first participant reached the second obstacle, he walked to its edge and looked down to see if he could spot anything in the water.
After several moments, the man sighed in relief when he saw nothing and, after taking a deep breath, jumped into it and began swimming.
The pool was even longer than the first obstacle. In fact, it was ten times as long.
As the participants continued to swim, they grew increasingly anxious, fearing that something might attack them from below.
Sure enough, once they reached the middle, they encountered a trap, but it was not what they had expected. Rather than arrows or attacks from beneath the water, whirlpools appeared on the surface, disrupting their rhythm and making it difficult to swim.
These whirlpools were weak at first, but they grew stronger and more violent the farther the participants progressed. Eventually, they became powerful enough to drag anyone who was not careful into the depths.
