Duan Muxiao's eyes gleamed with a hint of brilliance, and within his pupils, Chen Fei's figure was reflected.
At this moment, Duan Muxiao was less than twenty miles away from Chen Fei, and he had been following Chen Fei for a full hour.
And from half an hour ago, Duan Muxiao had maintained this distance, continuously observing Chen Fei.
Eye techniques and concealing one's aura, these were all essential techniques for the assassins of the Death Shadow Sect. A killer of the Combined Aperture Tempering realm level, like Duan Muxiao, sometimes, by observing the target's aura and movements, one could gather a lot of information.
Just like Duan Muxiao at this moment, even though he was twenty miles away from Chen Fei, he had already begun to integrate a lot of information about Chen Fei and correspond it with the data from his sources, confirming his own information about the target.
