The Light-and-Dark Prison Dragon, Starting at Super God Academy

Note: Be sure to read the entire blurb An all-powerful being that brought together the supreme power of countless planes forged it into the Great Wish System, then tossed it to a lucky person to help him fulfill every dream. But there was one condition: he had to obtain the energy needed to run the System himself... However, in an accident, he, who had originally merged with the Holy Dragon, instead devoured the power of darkness! If you want to read the dragon story, start from Chapter 22. Honestly, the first few chapters are a bit messy and have too much filler (that’s what the readers said). After Chapter 22, it’s the Armor World, and the story will return to the Super God World.
