Both of them were his bodies. When his main body was talking to Ming Long, his Heaven Devouring Avatar was completely immersed in devouring. That was the primitive instinct of that body. 

He had transformed into a ball of black mist and was ripping the body of that demon bit by bit. After which, the more frightening part was his ability to convert energy. The flesh of the demon and even his Primordial Spirit, Violet Kingdom Primordial Energy, and other parts that ordinary people couldn't control were also devoured and converted to his own strength. 

The entire Heaven Devouring Avatar only cares about one thing: devouring.  

This existence could be classified as energy or Primordial Spirit. Regardless, everything was fused together. He could think, he could transform, he could attack, and he could devour. 

For him, the body of the octopus demon was just like a huge mountain. 

His current fragile body would likely take a few days to completely devour it.
