As Nian Bing sensed everything within Green Mountain, he had already reached the midpoint of the mountain's slope at a speed difficult to discern with the naked eye. The closer he got to the mountain summit, the stronger the evil aura became. Although this dark, sinister energy filled Nian Bing with a feeling of power, it simultaneously stirred the desires inherent in his zombie origins, filling him with a bloodthirsty sensation. If not for Nian Bing suppressing that dark longing with his formidable spiritual power, he might have already let out a furious roar. Nevertheless, the surging death energy within him escalated his caution. Dark energy was a double-edged sword; as it enhanced his strength, it also posed a constant risk of backlash. Nian Bing understood that his first priority was to ensure his own mental clarity.
