[Mythology Crossover] The Dragon's Treasure

A dragon that will destroy the world x a rainbow-haired young man Midgard Private Academy is a school for nonhumans hidden within human society. Its students include vampires, werewolves, other nonhumans, and humans with special talents. At the entrance exam for the academy's 300th class, Ye Yi looked at the test grounds, which resembled a primeval forest, and fell into deep thought. Ye Yi: Why is it so hard just to go to school? Nidhogg yawned. His little gem was troubled, so he had to do something about it... Achoo! His dragon breath set the whole forest ablaze, reminding the exam proctors of the terror they felt as the World Tree was constantly gnawed upon and Ragnarok drew near. Ye Yi: You burned our meal ticket. Nidhogg: I swear I only meant to sneeze. "Odin, we found the Rainbow Bridge!" "Where? Hurry and bring it back!" "It's in Nidhogg's hands." "..." "Let's go, let's go. Our lives matter more." "I think Midgard is pretty nice. Why go back to Asgard?" This story could also be called The Rainbow-Haired Heartthrob and His World-Destroying Dragon or The Dragon Who Lives with a Rainbow-Haired Heartthrob Can't Get Enough of Shiny Things. The mythology has been heavily adapted. Don't ask why the gods are so scared of Nidhogg. The author just wants to write about a dragon that destroys the world. In the eyes of the Norse gods, the Rainbow Bridge is the only way to reach the realm of the gods. In Nidhogg's eyes, the Rainbow Bridge is a walking, talking rainbow gemstone. If it's a gemstone, it's his! In the Rainbow Bridge's eyes: I'm a pretty little fairy boy. The author's new story: High Danger Behind the Door [Infinite] Blurb: Shou: If you open this door, you'll die. Gong, unfazed, pushes the door open. A monster behind the door gets killed the moment it appears. The world is divided into what's behind the doors and what's outside them. People have to open doors to gain more time to survive. The world behind real doors is safe, while fake doors lead to a dangerous world full of monsters. Everyone has an innate talent. The shou's talent is: seeing real doors. Every door he sees is real. Opening one easily grants him more time, like he's cheating. But opening real doors attracts the monsters that have escaped from behind them, so the shou, who's terrible at fighting, uses an item to bind himself to a gong with overwhelming combat prowess. And yet... "Who knows why he wants to open the fake door!?" "Stop! Don't touch that door!" Recommended ongoing story by my author friend: I Want Your Pheromones by Huangchuan Dai (It's super sweet.
