With only six hours left on the timer, Leon didn't have as much time as it might seem at first glance because the clock speedsters were incredibly difficult to catch even when you had all the time in the world.
Because although he could theoretically kill all of the clock speedsters in a matter of minutes if he could actually get to them, doing that was by far the hardest part of this entire challenge.
After six hours of constant effort and no success whatsoever, the situation seemed to truly be impossible for any normal player to complete.
Killing them was impossible because they were simply too fast to hit with any attack, and even trying to overwhelm them with sheer strength was too difficult due to how strong they were physically when they decided to fight back.
Leon couldn't use [Abyssal Slash] to hide in the darkness either, since he couldn't jump from island to island in that form and would just fall into the void.
"Kikiki!" the monsters continued to laugh at him.
