Song Lan deeply felt the malice of the "pit" world.
He had initially thought that those who were forcibly sent into the "pit" all died under the fangs and claws of mutant constructs, but the real danger of the "pit" lay in the fact that it was an endless cycle.
Even if you were as brave and skilled in combat as the Commander of the First Army Corp, you could still potentially lose yourself amidst the endless cycles and the relentless slaughter.
In fact, if it weren't for the mind link of Yeying, they would probably have a hard time noticing the strange aspects of the "pit"'s space, for the environment inside was all too similar, coupled with the occasional attacks from mutant constructs and malevolent consciousness entities, making it difficult for those who ventured in to realize they were caught in an incessant loop.
By the time they became aware of this, they might already be in a state of utter depletion and at a dead end.
