How could the soul+devouring creature understand that the shitter that was destroying its mentality was treading in a path far greater than all the paths? A path so great that even Night the ruler of all the Ruler of all's will praise it.
The path wasn't boosted solely by Feng but also by all the being he had decided to protect. He had decided to protect the mortal and the mortals had decided to protect their lives. Two sides combined and godly energy was created. The energy that could feed the number one physique in the universe without a problem. Half of the dragon power could be seen being drawn out of Feng while the other heart was golden like the burning will to survive of the mortals.
