The group moved forward at slow steps. Colen was already showing an ugly face with each meter moved. Gomat was also suffering, but not as much as Colen. Ao, Mirrer, and Ula were more or less at the same condition as Colen too. As for Krune, well, he was following Ao and the others at his own pace. He could have gone ahead, but he didn't want to catch attention.
Between 10500 and 11000 meters mark, Colen, Ula, and another two guys that Krune didn't know the name finally reached their limits. There was no such thing as sitting and get used to the pressure anymore. Once they stopped, that would be because they can't resist. Just like that, those four lost their consciousness, and only their energy flags were left behind.
