In the long tunnel, Zhang Yuan endowed himself with the special vision of the Red-eyed Crow.
Although he could see in the dark, he couldn't maintain normal vision in extreme conditions.
Therefore, only by relying on the special ability of the Red-eyed Crow could he move freely without being blinded in pitch-black places.
The giant sandworm Zhang Yuan just killed had burrowed a tunnel that was extremely long and deep, winding like a maze, seemingly endless.
The unnerving thing was that walking in this wormhole, one could faintly perceive that massive creatures were moving through the sand nearby, their frictional sounds constant.
Zhang Yuan speculated that more sandworms were lurking beneath this ancient desert city.
Or perhaps he was heading towards a worm nest!
This forced Zhang Yuan to use the Body Technique of 'Carefree Travel', allowing himself to move as silently as a feather.
At the same time, he also concealed all his aura.
