If Di Tou was an ice cream machine, at the Nascent Soul Stage he would only have the 'vanilla' flavor. At the Resonance Stage, he was then a machine with both 'vanilla' and 'chocolate.' As for the Void Returning Stage, even if the ice cream machine could still only pump out the same amount of ice cream, there were now dozens more flavors, ranging from 'chocolate' to 'strawberry!' F*ck, he could even pull out sprinkles and toppings if that was what you wanted. Not to mention that he could combine them to create all sorts of new and wonderful effects.
And yet, Di Tou only knew how to pump out 'vanilla'. With such capability, although Di Tou was still using 'all of his strength', it was clear he was lacking in many areas. Even if he practiced some and learned about 'chocolate' or any other flavor, at most, he could pump them out individually like he had once pumped out 'vanilla.'
