After ending the call, Klaus remained seated at the mountain peak, showing no sign that he was aware of the people sneaking toward him. Ever since he had transformed his spiritual Qi into Star Qi, his senses had sharpened dramatically. Now, he could sense anything within a 50-kilometer radius—a feat typically only possible for those at the Saint stage.
At the Saint level, one's senses evolve into Divine sense, allowing for perfect awareness even with closed eyes. Though even Divine sense has its limits, Klaus, who hadn't yet reached the Master stage, could already detect the slightest disturbance within his 50-kilometer range.
As soon as Klaus sensed the approaching group, he knew they had bad intentions. While he couldn't see them directly, his heightened awareness allowed him to track their movement patterns. It became clear to him that they were coming for him—and they weren't coming in peace.
