Sui Xiong was moving at a very high speed, and the speed at which he fought against the demons was also very fast.
This was determined by the way he fought. He did not want to fight a slow battle against the demons at all. He simply gathered all his strength and burst out all his might in one breath. With his strong tentacles, he wrapped the demons firmly in his grasp and dragged them to him. Then he spread out his body and devoured them all.
This was a very crude method and caused him many injuries that he could have avoided in the first place. But it proved to be very effective.
The demons were powerful, but this was never because of their strength. Speaking purely in terms of brute force, there were not many among the demons who were truly herculean. And there was only one who could fight Sui Xiong, who was only such a big and unreasonable monster by virtue of its brute force.
This was one of the veteran demons, and its name was "Herculean Hagrid."
