Lu Zhou knew the 'rat' could hear him. He was not in a rush. He hovered in the air and recited the mantra for the power of hearing.
Lu Zhou could smell the intruder's aura clearly. He could even smell changes in the density of the aura that was slight as a strand of hair. The cold aura lingered in all four directions. Nevertheless, he knew it would be rather difficult to find this rat that was rather good at hiding even if he knew the general area where the rat was hiding just by relying on the power of smell alone.
The sound of the wind and grass in the surroundings entered Lu Zhou's ears as he searched for the sound of breathing and heartbeat.
Only a true expert could suppress his breathing and heartbeat, appearing dead, in this kind of situation.
