The super high score of the demon tail, the dance performance of the big demon fight and the plot after that

This is my personal plot guess (please don't spray). Ten thousand dragons attack together. Naz and others resisted, but there were too many dragons and they didn't win in the end. Just when Naz was desperate, a man in strange clothes appeared in front of everyone. Strange clothes can be imagined as protective clothes in death, but the color is changed to red. ) He calls himself Brad, and is known as the god who manipulates fate, becoming a millennium demon. Without waiting for everyone's reaction, he gave Naz two things without saying anything, one is a necklace embedded with golden magic crystals, and the other is a golden pocket watch, saying that Naz was originally the president of a guild 400 years ago and one of the heirs of the Dragon King in human form. The trade union is a trade union dedicated to helping mankind resist the dragon attack, but once, a member of the trade union was manipulated by Akron Noah, a demon made in jelf. Don't turn union members into black dragons. Naz was defeated by the black dragon because he couldn't do it. Brad had no choice but to take Naz. Naz recalled everything, lit a special flame that only belonged to him-the golden inflammation of the dragon king, and repelled the dragon. Then Brad left a bloody book, which read: "I want to reply to other people's memories 400 years ago." When everyone arrives, I will appear again. " Naz then met with people from his own trade union and his brother's trade union (I forgot to mention, the trade union people are all people who destroy the dragon magic religion), and then he launched a conspiracy to crusade against the Black Dragon and jelf.
