About two hundred meters away, beyond two hundred meters, Lu Yu could only hear the sound of disputes in the air; the spirit markers transmitted no sound.
Knowing the limit of the spirit markers' sensory range inside the Sand King Hall, Lu Yu's objective became clearer: he only needed to get within two hundred meters of the Shura demons to overhear their conversations and eavesdrop on their secrets.
Lu Yu revealed a satisfied smile and headed toward the direction of the fourth spirit marker, which was placed on a member of the Sand King Hall who held the sand soil.
Currently, Lu Yu could use 20 spirit markers—one on Xue Ming, one on the Shura demons, another on a guard of the sand storehouse, and the last one on a member of the Sand King Hall.
He followed the spirit marker and walked towards the place where he had previously dealt with that sand envoy; that place was probably an important area within the Sand King Hall.
