They are mountaineers. On their days off, they all go climbing together and reach summits without much trouble. This time, they decided to set their sights higher, taking a long break to climb one of the world's top three peaks, standing at 8,586 meters. Midway through the ascent, everyone began to notice something was wrong. The path had vanished, and they had strayed from the route. However, with poor visibility and unstable footing, turning back was not an option. As they continued to climb, they eventually realized they were completely lost, with no path ahead and no way back.
